Answer:
The correct answer is - 2 ATP and 2 pyruvic acids.
Explanation:
The given model represents the glycolysis pathway which is the first of the key metabolic step of cellular respiration. It helps in producing the energy in form of ATP through breaking down a glucose molecule into 2 molecules of pyruvic acid and with a series of enzymatic reactions.
This process also releases energy in the form of 2 molecules of ATP and NADH. The pyruvate or pyruvic acid molecules then moves to the link reaction, where acetyl-CoA is produced.
Thus, the correct answer is - 2 ATP and 2 pyruvic acids.

Answer:
Answer:C) The patient may have internal bleeding and cuts may not stop bleeding.
Explanation:
Platelets are cells that form scabs to help stop the bleeding of wounds. When you have low platelets, you can have fewer scabs at a time, so wounds will bleed more. If you have dangerously low platelets, any wound you have will not close and you will not stop bleeding without outside help.
Areas on the moon called maria Select one: a. are seas of water. b. consist of basaltic lava. c. formed a million years ago. Clear my choice
Areas on the moon called maria consists of basaltic lava. Option B is correct.
The areas on the moon called maria are not actually seas of water, as option a suggests. Instead, they are large, dark, flat areas on the moon's surface. These areas were formed by ancient volcanic activity.
Maria are made up of basaltic lava, which is a type of lava that is low in viscosity and can flow easily. When volcanic eruptions occurred on the moon in the past, this lava flowed out onto the surface and covered large areas, creating the maria.
These volcanic eruptions and the formation of the maria took place billions of years ago, not just a million years ago as option c suggests. They are remnants of the moon's early history when volcanic activity was more prevalent.

Describe how Stella’s view of these plant cells and their parts changed as she transitioned through the three levels of magnification. Be sure to identify at least one cell structure or part of the leaf cells in your description.
Answer:
The three different views show different level of magnification.
Explanation:
At the first level the structure of plant cell is not clear however upon more magification the view is clarified and the upper epidermis and the lower epidermis are both visible in the third view which is the most magnified. The parts of leaf cell are visible the most evident of them is the epidermis which protects the outside of the cell and also Palisade Mesophyll is visible which helps in photosynthesis.
Answer:
At the first level, the structure of the plant cell is not as clear, but when the image is at 100x, the plant cell is magnified and a lot of detail can be seen. At 400x, which is the most magnified, the details are more and the image is larger, allowing Stella to take note of it. Palisade Mesophyll is part of the cells of the leaves and helps in photosynthesis.
The Grey Cat.
Each day you take a walk at a different time following the same route. Along your path there is a bus stop with a bench located at the bottom of a hill. Upon this bench sits a grey cat. Each day, as you pass this grey cat, you say “hello cat”. You’ve recognized that each day, as you do this, a bus consistently comes over the hill. The consistency of this events sparks your interest, it seems to go beyond the possibility of coincidence. In order to satiate your curiousity you have decided to design an experiment to investigate the anomoly.
Working with just the information provided, create a GOOD Hypothesis about the above scenario. Generate an experiment to test your hypothesis, and write an experimental design. Your experimental design writeup must clearly define all essential aspects of the experiment.
Note: Avoid suppositions at all cost! Work with only the information provided. This is science.
Hypothesis: There is a synchrony between the time the bus passes over the hill, the time the cat is positioned on the bench and the time I talk to the cat.
An experiment will be established to prove or deny this hypothesis. This experiment will try to answer if there is a synchrony between the bus, the cat and me.
First, I will write down the time I usually leave the house for the bus stop and then I will look for a schedule of the buses in my city, to evaluate the times when each one passes above the hill to which I refer.
It is necessary that I clock the time spent between my home and the bus stop to which I am going, so that I can relate to the bus schedule.
I must also install a camera system at the bus stop to observe the times the cat arrives at that location.
Every day, for a month, I will write down the time I left home, the time I arrived at the bus stop, the time the cat arrived at the bus stop and the time the bus passed. At the end of this period, I will do average calculations to find out how many times our schedules have been synchronized. Through these data I will conclude whether the hypothesis is false or true.
what is the term that describes what occurs when genetic drift results in the formation of a new population that has less variation than the original population had A. Speciation B.Founder effect C.Mutation D. Sexual selection .
Answer:
A. Speciation
Explanation:
Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
When the genetic drift occurs due to various factors and results in the formation of a new species it is called speciation. Thus, option A is correct.
What is speciation?Speciation is the formation of a distinct species from the original population because of the genetic drift that caused evolutionary changes essential for survival.
The species are separated from their original population leading to variation in the gene pool resulting in reproductive isolation and finally, the new species is formed.
Therefore, option A. speciation results in distinct species.

Explanation:
Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados Genes.

Modern domesticated pigs are descendants of the wild boar(Susscrofa). Through the domestication process, human have artificially selected for certain traits. Identify two of these traits, and briefly explain how they benefit modern society. Be sure to identify the trait, explain why it was artificially selected and how it benefits modern society.
Answer:
Meat for food and small size for pets
Explanation:
Artificial selection is the process by which humans control desirable phenotypic characteristics in plants and animals by applying selective breeding techniques to perpetuate these traits in the population. A example of artificial selection includes the process of domestication of modern pigs (Sus domesticus). It has been shown that the modern pigs derived from the wild boar (Sus scrofa), which were domesticated separately 9,000 years ago in China and Western Asia. For example, by artificial selection, humans have domesticated moderns pigs to use them as livestock for direct consumption (i.e., for their meat). Moreover, there are pig populations that have been artificially selected as pets (e.g., miniature Vietnamese Pot-Bellied pigs).

In this project, you will analyze claims about the causes of inherited genetic variation. You will then make your own claim based on prior knowledge. Next, you will defend your claim by conducting research to gather information that supports it. Finally, you will present your claim and defense in a typewritten paper.
Answer:
The two major causes of the inherited genetic variation are 1-mutations during DNA replication and 2-crossing over during meiosis
Explanation:
The mutations are changes in the genetic information that may be inherited when they occur in germline cells (i.e. sperms and ova). Mutations include single nucleotide polymorphisms (SNPs), insertions and deletions (collectively named indels), and major chromosome arrangements such as, for example, aneuploidy, centric fusion, duplications, etc. On the other hand, the crossing over or recombination is the exchange of genetic material between non-sister chromatids of homologous chromosomes during Prophase I of Meiosis. Recombination is a phenomenon that generates new genetic combinations in the gametes and thus increase genetic diversity. Both germline mutations and crossing over events increase genetic variation in the offspring of the next generation, thereby these phenomena represent sources of inherited variation.
During labor, certain hormones are released that cause the contraction of the uterus in order to push the baby out. When those hormones are sensed by the glands of the endocrine system, they secrete more of that hormone which keeps labor going until the baby is born.
Answer:
The endocrine system assists in maintaining and regulating different functions of the body by producing and discharging hormones. It comprises glands situated throughout the body, which produce chemicals known as hormones directly into the blood. The levels of hormones in the blood are monitored by a highly unique homeostatic mechanism known as feedback.
The two kinds of feedback are common, that is, negative and positive feedback, of this positive feedback, is the rare mechanism. It augments the changes done rather than opposing them. For example, the discharging of oxytocin from the posterior pituitary gland at the time of labor is an illustration of a positive feedback mechanism.
The stimulation of the muscle contractions, which pushes the baby via the birth canal is done by oxytocin. This discharging of oxytocin leads to an augmented or stronger contraction at the time of labor. This contraction is enhanced and intensify until the baby comes out of the birth canal. However, when the stimulus to the pressure receptor terminates, the generation of oxytocin ceases, which eventually results in the stopping of labor contractions.

Describe under what conditions you might expect your cells to undergo anaerobic respiration. Be specific as to why these conditions would prevent normal cellular respiration to proceed. What product is produced under anaerobic conditions and is it harmful?
Answer:
Explanation:
Cells start undergoing anaerobic respiration when energy requirement is high and there is not sufficient availability of oxygen to produce required energy .
For example , when we we run fast , energy requirement by muscle cell is high but available oxygen level is not sufficient so cells start anaerobic respiration which produces lactic acid and this product creates tire-ness.
For normal respiration , oxygen is required . If there is lack of oxygen , aerobic respiration is not possible .
In yeast cells , alcohol is produced by anaerobic respiration. Alcohol is not harmful . In muscle cells , lactic acid is produced which is harmful .
Two examples of how plants move include changing location as part of reproductive strategies and their growth in response to different environmental factors. Explain the impact one of these examples may have on secondary succession in an area after a significant disaster.
Answer:
Secondary succession occurs when the severity of disturbance is insufficient to remove all the existing vegetation and soil from a site. Many different kinds of disturbances, such as fire, flooding, windstorms, and human activities (e.g., logging of forests) can initiate secondary succession. Pioneers of secondary successions face quite different conditions from those that accompany primary succession. Secondary successions often start with resource-rich conditions associated with high light availability and reduced competition for nutrients and moisture. Disturbances may also be short-lived; for example, gaps created in forest canopies close as the crowns of surrounding trees expand and as seedlings and saplings in the understory grow up in response to increased light. Pioneers rely on recruitment from propagules present in the soil, or that disperse into the site after disturbance occurs. Pioneers are able to outcompete established vegetation that survived the disturbance by maintaining high juvenile growth rates. Some of the fastest growing trees are pioneers in tropical rain forests. Individuals of the balsa tree Ochroma pyramidale, for example, can grow from seedlings to adults with >30 cm trunk diameter in <10 years.
The difference between pioneer and nonpioneer species is difficult to delineate (Table 1). Attempts to define distinct life-history strategies (implying coordinated evolution of life-history traits) are confounded because key traits such as propagule size and juvenile growth rate can vary over several orders of magnitude within a community and show broad overlap among species with contrasting habitat requirements. Nonetheless, interactions among traits can be used to describe some life-history tradeoffs that largely constrain the habitat requirements of pioneers. For vascular plants, paramount among these is a tradeoff between growth in the sun and survival in the shade (Figure 3). The high growth rates of pioneers are maintained by allocating a large fraction of the plant’s resources to new leaf area production, and by investing in nutrient-rich leaf tissue that can attain high-maximum photosynthetic rates. A consequence of preferential allocation to leaf production is that few resources remain that can be used to defend the plant against herbivores and pathogens, or to recover from physical damage. This results in high mortality, particularly in the shade, where resources needed for tissue replacement are most limiting.
