Which of the following statements is not a characteristic of the prokaryotes.

Prokaryotes don't have a nucleus.
Prokaryotes have a cell wall.
All of the chemical processes take place in membrane bound organelles in the cytoplasm.

Answers

Answer:

All the chemical processes take place in membrane bound organelles in the cytoplasm.

Explanation:

Use the process of elimination:

One of the main things that make a prokaryote is not having a nucleus, so that can be eliminated.

Looking at the structure of bacteria, they can have a cell wall, so this is eliminated.

Therefore, “all the chemical processes take place in membrane bound organelles in the cytoplasm” is incorrect.

Also, prokaryotes DO NOT have membrane bound organelles like mitochondria, chloroplasts, or a nucleus, so this statement would also be incorrect because of this.

What helps weaken atp bonds so energy can be released and then later help reform them?

Answers

Enzymes help weaken these bonds so energy can be released and then later help reform them.

that's the answer

ADP (adenosine diphosphate) is formed when these high-energy connections between the phosphate groups at the end are broken, releasing energy for the cells to utilize.

How is energy stored in ATP?

One phosphate group is left on its own, these powerful associations may be broken and rebuilt with the aid of enzymes.

When a third phosphate is added to the ADP molecule, reforming ATP, water that was broken down into its hydrogen atom and hydroxyl group during ATP hydrolysis is recovered.

Energy must be introduced into the system to regenerate ATP, ADP develops and energy is released for the cells to utilize when these connections are broken.

Therefore, ATP has the capacity to store and transmit chemical energy, high-energy bonds are used to link the final two phosphate groups.

Discuss the unique properties of water. (Polar, Hydrogen bonds, Cohesion, Adhesion)

Answers

Answer:

Water has cohesive and adhesive properties.

Water molecules have strong cohesive forces due to their ability to form hydrogen bonds with one another. Cohesive forces are responsible for surface tension, the tendency of a liquid's surface to resist rupture when placed under tension or stress.

Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. ... Cohesion: Water is attracted to water, and Adhesion: Water is attracted to other substances.

Answer & Explanation:

The difference in electronegativity between oxygen and hydrogen atoms creates partial negative and positive charges, respectively, on the atoms.

Water molecules attract or are attracted to other polar molecules.

Molecules that do not dissolve in water are known as hydrophobic (water fearing) molecules.

Because of its extensive hydrogen bonding, water (H2O) is liquid over a far greater range of temperatures that would be expected for a molecule of its size. Water is also a good solvent for ionic compounds and many others because it readily forms hydrogen bonds with the solute.  

Cohesion holds hydrogen bonds together to create surface tension on water.

Since water is attracted to other molecules, adhesive forces pull the water toward other molecules.

Water is transported in plants through both cohesive and adhesive forces; these forces pull water and the dissolved minerals from the roots to the leaves and other parts of the plant.

Key Terms:

hydrogen bonds: A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

adhesion: The ability of a substance to stick to an unlike substance; attraction between unlike molecules

cohesion: Various intermolecular forces that hold solids and liquids together; attraction between like molecules

hydrophilic: having an affinity for water; able to absorb, or be wetted by water

hydrophobic: lacking an affinity for water; unable to absorb, or be wetted by water

polarity: The intermolecular forces between the slightly positively-charged end of one molecule to the negative end of another or the same molecule.

Previous genetic analysis has shown that fur color in this species is controlled by a single gene that has two alleles: a dominant allele (FF) that is associated with dark fur, and a recessive allele (ff) that is associated with light fur. The scientists collected data about a population of these mice to help determine the population's fur color allele frequencies. They found that out of 952 mice in the population, 238 mice had light fur. Assuming that the population is in Hardy-Weinberg equilibrium, which of the following is the number of mice in the population that have the genotype FfF, f?

Tại sao con người chúng ta lại sốt nhiều lần như vậy?

Answers

Answer:

Fever is an elevated temperature of the human body that is substantially beyond the normal range. Normal body temperature fluctuates daily from about one degree below 98.6 degrees Fahrenheit to one degree above that number. Lower body temperatures usually occur before dawn; higher temperatures in the afternoon.

Body temperature also varies slightly depending on where on the human body it is measured. Rectal (internal) temperature tends normally to be higher than skin (surface) temperature. Oral and armpit temperatures can approximate actual body temperature and are more convenient to measure.

One of the most common plants in Atlantic salt marshes is cordgrass. periwinkle snails cling to the top of tall cord grass is during high tide. The tall cord grass is provide protection from the snails predators such as blue crab. well the snails do not be directly on cordgrass the snails can damage the cord grass when they grays and algae and fungi that grow on the grasses. if the snail populations grow too large they can decrease cord grass growth.

Answers

Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails. Hence option B is correct.

Biotic factors - The living components or the living things that are present in the ecosystem that shapes the environment are known as biotic factors. Examples are plants, bacteria, algae, birds, fishes etc.

A ecosystem runs through the interaction of biotic and abiotic component.  Biotic supplements acts as a fuel that supports the bacterial growth.

Periwinkle snails graze on the top of the cordgrasses to escape from their predators blue crab. They graze on the fungi and algae that is inhabitant on top of the grass, they do not feed directly on the cordgrass

While grazing they actually damage the cordgrass by spreading the fungal infection.

Hence, option B is Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails is correct.

The correct question is :

One of the most common plants in Atlantic salt marshes is cordgrass. Periwinkle snails cling to the top of tall cordgrasses during high tide. The tall cordgrasses provide protection from the snails’ predators, such as the blue crab. While the snails do not feed directly on the cordgrass, the snails can damage the cordgrass when they graze on algae and fungi that grow on the grasses. If the snail population grows too large, it can decrease cordgrass growth.

Question

Based on the passage, which of the following describes the ecological role that cordgrass serves for the snails?

Responses

A. Cordgrass is a biotic factor for the snails because it is the snails’ main food source.

B. Cordgrass is a biotic factor for the snails because it is a living source of protection in the Atlantic salt marshes for the snails.

C. Cordgrass is an abiotic factor for the snails because it provides habitat for the snails and crabs.

D. Cordgrass is an abiotic factor for the snails because it produces algae and fungi for the snails.
