Answer:

> Consumers convert glucose from producers into ATP.

Explanation:

Consumers do NOT provide oxygen or glucose for producers.

The statement, consumers convert the glucose from producers into ATP. So the correct option is D.

In feeding chains, organisms are categorized into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.

Autotrophs, another name for producers, grow their own food. Every food chain's first level is comprised of these. Plants or single-celled creatures represent the majority of autotrophs. The majority of autotrophs produce their "food" (a nutrient called glucose) from sunlight, carbon dioxide, and water through a process known as photosynthesis.

The most well-known form of autotroph is a plant, but there are numerous others as well. Algae are autotrophic, and their bigger forms are known as seaweed. Autotrophs include the small sea life known as phytoplankton. Autotrophic bacteria include certain varieties. For instance, microorganisms that live in volcanoes that are still active utilize sulfur compounds to make their own food. Chemosynthesis is the name of this process.

Therefore the correct option is D.

The plant will swell and possibly burst if the cell walls are weak. So, the correct option is A.

A cell wall is an external structural layer that surrounds some types of cells. It may be hard, flexible, or occasionally rigid. It serves as a filtration system as well as structural protection and support for the cell. The cell wall composition varies according to the organism which is permeable in nature

The cell wall isolates the inner elements from the surrounding environment. The cell as well as its organelles are also development in the context, support, and protection by it. But only eukaryotic plants, fungi, and a few prokaryotic creatures have this cellular component. If the plant's cell walls are insufficient in the case above, it will enlarge and possibly burst.

Therefore,  the correct option is A.

Equation

Explanation:

the last word is Equation

Considering the definition of chemical reaction and chemical equation, A chemical reaction can be mathematically represented by showing the required amount of products and resulting reaction components using a chemical​ equation.

A chemical reaction consists of the formation of new substances (products) from others (reagents). In this process bonds of the reactants are broken and new ones are formed in the products.

In other words, a chemical reaction occurs when the substances participating in it are transformed into different ones. The mass of the participating substances is the same before and after the reaction, that is, it is conserved because only a rearrangement takes place between the atoms of the reactants, which break and form new bonds.

Chemical reactions are represented by chemical equations. In them, the reactants are determined, the products are predicted, and the proportions of the substances that participate in the reaction are indicated.

Answer:okay so I did it it was very fun so here are my results EXPERIMENTAL DATA  Before After 24 hours

Explanation: Conclusion

The conclusion to this test is that the plastic bag is permeable to iodine. The result

of this experiment clearly answers the "Problem" as stated above. This is~ by

the fact that the starch solution (dependent variable) in the baggie turned purple,

indicating the presence of iodine (independent variable) in the mixture. The starch

solution is the dependent variable because its color is affected by the iodine

solution. M.y hypothesis was that the iodine will get into the bag of starch because

the baggie is permeable to iodine. If the iodine solution penetrates the bag, it will

turn the starch solution inside the baggie, purple. The control data chart above

shows that if the starch had not been immersed in the iodine solution, but rather a

water solution, it would have remained the same color, white. Obviously, in order

for the iodine to enter the starch solution, the baggie must be permeable to the

iodine. The baggie represents a cell membrane. This lab is meant to demonstrate

whether or not a cell membrane is permeable to substances. Cell membranes of

living organisms may be permeable to some substances, but not permeable to other

substances. In this experiment,'1..charted that the iodine solution in the beaker did

not turn purple. This means that the starch solution did not penetrate the baggie

and therefore did not mix with the iodine outside the baggie. Because of this data, it

is clear that the plastic baggie is not permeable to starch, but is permeable to iodine.

In a cell membrane, this is called selective permeability. In other words, the iodine

can go through the baggie, but the starch cannot. The purpose of this experiment is

to show that a cell membrane is a type of barrier, and is permeable to some

substances, but may not be permeable to all substances. Therefore, a cell membrane

is selectively permeable.

Answer and Explanation

Explain why populations tend not to continue to increase exponentially in an environment: The exponential growth model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size. A population that exhibits exponential growth model increases in proportion to its size. In the Logistic growth model, the population growth depends on density, the natality and mortality rate depends on the population size, which means that there is no independence between population growth and population density.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

Explain what is meant by environmental resistance: It refers to the limiting factors. There are factors and conditions that regulate the population growth, that might be biotic or abiotic, and that avoid the over-growth of a population in a certain space. It results in a natural equilibrium of its biotic potential.  

Explain what is meant by carrying capacity: The carrying capacity K is the maximum point delimited by available resources, such as food or space.

K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.

Explain the importance of carrying capacity to the growth and maintenance of population numbers: If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.  

Explain why a newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth: The example of the rabbit is a case of invasion. Biologic Invasions refer to new species that disperse and establish in a new area far or out of their original distribution range. Once established, these species expand their distribution from the first invaded spot and overgrows. Once stablished, they expand. In the new area, they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their overgrowth and consequently uncontrolled expansion. At this point, the population is exhibiting exponential growth. They have enough food available, they might not have predators, they do not have enough competitors for food or space, and if they do they are adapted to live under harder conditions so they are able to compete. The new species is not suffering from the effects of limiting factors yet.  

Describe a likely outcome for a rabbit population after the initial rapid increase had slowed: There are some typical steps in an invasion process:

1) Introduction or dispersion to the new area,

2) Naturalization. The new species establishes in the new area. It can grow, reproduce and make use of resources.

3) Overgrowth and uncontrolled expansion.  Exponential growth

4) Interaction with other species.  At this point, they compete for limiting factors such as food or space. Their population is big enough to be affected by resource availability and by other species that interact with them. The invasive species reach the point in the curve where they stabilize.

5) Stabilization. They reach an equilibrium point.  

Describe the effect that introduced grazing species might have on the carrying capacity. The introduced species expand fast and consume too many resources. Available resources, such as food or space, decrease.

The populations tend not to continue to increase exponentially in an environment due to various environmental factors which restricts or limits its growth.

Environmental resistance refers to environmental factors that restrict the biotic potential of an organism or limit the increase in population. Carrying capacity refers to average population of specie's size in a particular habitat. The importance of carrying capacity to the growth and maintenance of population number because carrying capacity provides resources to a specific population of organisms.

Newly introduced consumer (e.g. rabbit) would initially exhibit a period of exponential population growth because of no predator present in the environment. The introduction of predators which feeds on rabbit is the outcome for a rabbit population after the initial rapid increase had slowed

There is a great effect of introduced grazing species might have on the carrying capacity because more introduced grazing species removes all the vegetation present in that environment which leads to imbalance of ecosystem.

Answer:

The complete explanation of the  immune response to a pathogen through the oral (oral-anus) and respiratory route is given below in explanation part .

Explanation:

In order to provide host protection against pathogens wherever they can enter or spread, the immune system can be seen as an organ distributed throughout the body. A collection of anatomically distinct compartments can be distinguished within the immune system, each of which is specifically adapted to produce a response to pathogens present in a specific set of body tissues. The basic concepts underlying the initiation in the compartment of the peripheral lymph nodes and spleen of an adaptive immune response. This is the compartment that responds to antigens that have dispersed through the blood or penetrated the tissues. The mucosal immune system (commonly represented by the MALT) is a second compartment of the adaptive immune system of equal size to this, and situated near the surfaces where most pathogens enter. Body cavities (peritoneum and pleura) and skin are two other distinct compartments. These compartments are characterized by two main characteristics. The first is that immune responses induced within one compartment are generally restricted to that specific compartment in terms of speech. The second is that by expressing homing receptors that are bound by ligands, known as addressins, which are specifically expressed within the tissues of the compartment, lymphocytes are limited to particular compartments. The body's mucosal surfaces are particularly susceptible to infection. Because of their physiological roles in gas exchange (the lungs), food absorption (the gut), sensory roles (eyes , nose , mouth, and throat), and reproduction (uterus and vagina), they are thin and permeable barriers to the interior of the body. Obvious susceptibility to infection is provided by the need for permeability of the surface lining of these sites and it is not surprising that the vast majority of infectious agents via these routes enter the human body.

When contemplating the immunobiology of mucosal surfaces, a second essential aspect to bear in mind is that the gut serves as a conduit of entry in the form of food to a large array of foreign antigens. The immune system has developed mechanisms to prevent, on the one hand, a robust immune response to food antigens and, on the other, to detect and destroy the entry of pathogenic organisms via the gut. The majority of the gut is heavily colonized by commensal microorganisms, which live in symbiosis with their host, to further complicate matters. In certain ways, these bacteria are beneficial to their hosts. They provide protection by occupying the ecological niches for bacteria in the gut against pathogenic bacteria. By synthesizing vitamin K and some of the components of the vitamin B complex, they also serve a nutritional role in their host.

Peyer's patches of the small intestine, the appendix, and solitary lymphoid follicles of the large intestine and rectum are the other major sites inside the gut mucosal immune system for the activation of immune responses. The patches of Peyer are an extremely important location in the small intestine for the activation of immune responses and have a distinctive shape, forming domelike structures that reach into the intestinal lumen. Specialized epithelial cells reside in the overlying layer of follicle-associated epithelium of the Peyer's patches. Instead of the microvilli present on the absorptive epithelial cells of the intestine, they have microfolds on their luminal surface and are known as microfold cells or M cells. By endocytosis or phagocytosis, M cells pick up molecules and particles from the gut lumen. This material is then transported to the basal cell membrane, where it is released into the extracellular space, via the interior of the cell in vesicles. This mechanism is referred to as transcytosis. The cell membrane of M cells is extensively folded at their basal surface around underlying lymphocytes and antigen-presenting cells that take up the transported material released from the M cells and process it for the presentation of antigen.

Metabolism is the process by which your body converts what you eat and drink into energy. During this complex biochemical process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.There are three basic metabolism types: ectomorph, mesomorph, and endomorph – definitely words you probably don't use in your normal, day-to-day conversations.If your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Cells use a molecule called ATP  to store and release energy like a battery. The energy is stored in chemical bonds between phosphate  groups of the molecule, and the energy is released when the chemical bonds are broken.

Explanation:

ATP (adenosine triphosphate) can be though of as a battery. It is also sometimes desribed as the energy currency of the cell. DNA and RNA are nucleic acids - the genetic information of the cell, and does not store and release energy. CMP is a nucleotide.

The energy found in ATP is found stored between phosphate groups of the molecule. When a phosphate group is released, it forms ADP (adenosine diphosphate)

Cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.

ATP is the energy coin of the cell whose hydrolysis is used to carry out many different metabolic functions (e.g., reproduction, differentiation, growth, etc).

ATP hydrolysis is a catabolic reaction, which provides releasable energy stored in the bonds between the second and third phosphate groups.

The molecule of ATP can transfer its energy to different molecules during many cellular processes such as, for example, DNA replication, active transport, muscle contraction, etc.

In conclusion, cells use a molecule called ATP to store and release energy. The energy is stored in chemical bonds between PHOSPHATE groups, and the energy is released when the chemical bonds are broken.
