Answer 1

Answer:

In nature, populations are usually evolving. The grass in an open meadow, the wolves in a forest, and even the bacteria in a person's body are all natural populations. And all of these populations are likely to be evolving for at least some of their genes. Evolution is happening right here, right now!

To be clear, that doesn't mean these populations are marching towards some final state of perfection. All evolution means is that a population is changing in its genetic makeup over generations. And the changes may be subtle—for instance, in a wolf population, there might be a shift in the frequency of a gene variant for black rather than gray fur. Sometimes, this type of change is due to natural selection. Other times, it comes from migration of new organisms into the population, or from random events—the evolutionary "luck of the draw."

I hope this helps a little bit.

Why is it difficult to fossilize large animals?

Answers

Answer:

The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

43. What are the elements found in nucleic acids?___________________________________
44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________

Answers

Answer:

42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine

Explanation:

43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

44.polymer of nucleic acid

33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.

what are 5 functions of carbohydrates ​

Answers

☁️ Answer ☁️

PROVIDES INSTANT ENERGY TO THE BODY:

This appears to be the primary function of carbohydrates in the body.

Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.

RESERVE FOOD:

Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.

CARBOHYDRATES FORM OTHER BIOMOLECULES:

Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.

DETOXIFICATION OF THE BODY BY METABOLISM:

Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.

SPARING PROTEIN

In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

Suppose you have the same mass of water and air. If you want to raise the temperature of water and air from 20°C to 30°C, which substance will require more energy, Q, to do so?

Answers

Water need more energy because the heat capacity c of the water is the greatest =4186

Answer:

Water has a higher specific heat than air. So, it will require more energy to raise the temperature of water from 20°C to 30°C compared to what is needed to raise the temperature of the same mass of air.

Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?

Answers

Answer:

DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell.

Explanation:

Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important
