What other traits are highly variable like human skin color ?

Answers

Answer 1
Our lack of body hair and our variable skin color are some of the traits that set us apart from our closest primate relatives. Wavelengths of light are reflected or absorbed by pigment in the skin called melanin. Melanin is synthesized in structures called melanosomes that are produced by cells called melanocytes.

What do you think would happen to the population of rabbits, if the population of foxes decreased?

Answers

Answer:

the population of rabbits might increase

Explanation:

With less predators to eat them, the rabbit population will likely go up if the fox population decreases; assuming there are favorable factors such as plenty of food and habitat for the rabbits. At some point, there is a maximum limit to the number of rabbits that a certain location can hold. Once this limit is reached, (some of) the rabbits will migrate elsewhere or unfortunately die off.

As the rabbit population increases, the fox population may rebound and start increasing again. This is due to more food being available to the smaller amount of foxes, and there is less competition for food. So the rebounding fox population will likely bring down the rabbit population to a point where food will get more scarce for the foxes. This cycle repeats itself where one population increases while the other decreases, and vice versa. They are very strongly linked together. It's also possible that both will increase together if environmental factors are favorable, but they could easily decrease together if a habitat is being destroyed for instance. It will depend on the circumstance.

Why the Chimpanzee's diploid number is 24 instead of 48.

I am not sure if the following table supposes me to write 2 (N) on here...

Thank you very much

Answers

Answer:

It has 24 pairs and 48 number of chromosomes.

Explanation:

The Chimpanzee's diploid number of chromosome is 24 pairs instead of 48 because of the resemblance with the human cell that have 23 pairs of chromosome. The Chimpanzee has 24 pairs of chromosome or another words we can say that chimpanzee has 48 number of chromosomes not pairs. Humans have 23 pairs whereas apes have 24 pairs of chromosome. The theory suggested about this close number of chromosomes is that at some point two ape chromosomes fused to make a single human one.

How is it possible for a mutation not to produce any visible effect in an

Answers

Answer:

Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.

The answer is nucleic acids

Nucleic acid is a substance in which the monomer is a nucleotide. Therefore, option B is correct.

What are nucleic acids?

Biopolymers and macromolecules called nucleic acids are important for all known forms of life. They are constructed of monomers called nucleotides, which are composed of a nitrogenous base (adenine, guanine, thymine, uracil, and cytosine), a phosphate group, and a 5-carbon sugar.

The components that make up an individual's genetic code are nucleic acids. Deoxyribonucleic acid (DNA) and ribonucleic acid are the principal two examples of nucleic acids (RNA). They have an important role in heredity and protein synthesis.

Thus, A nucleotide serves as the monomer of a material known as nucleic acid. Therefore, option B is correct.

Natural selection is the process in which the species are adapted to their environment.

Natural selection leads to evolution  when the people having certain characteristics posses the greater chance of survival than the others that are not adapted to the changes, these adapted characteristics are passed to the next generations.

(a) Describe why monitoring the growth rate of the E. Coli-M bacteria is a useful indicator of the effect of the glycolytic enzyme mutation on the bacteria.

Answers

Answer:

The monitoring the growth rate of E.Coli bacteria is a useful indicator of the effect of glycotic enzyme mutation on the bacteria as the flow of intracellular metabolic components depends on the availability of carbon. Hence the change in carbon source can change the glyclyotic enzyme mutation up or down.

Explanation:

Continuous culture is a method that can be used by the researchers for determining whether mutation affects the growth rate of E.Colin-M bacteria

If the growth medium contains higher concentration of acetate,then the growth of the bacteria will be inhibited without inhibiting its central metabolism.

When E.Coli grows ,it secrets acetate. This mechanism is called overflow mechanism. Regulatory interactions mediated by acetyl-phosphate plays a major role in inhibiting growth by acetate. The uncoupling effect of organic acids or perturbation of the anion composition of the cell is a major reason for growth inhibition.

What is Infrared radiation?

All objects, living or non-living, emit some amount of infrared radiation, which is a type of electromagnetic radiation with wavelengths longer than those of visible light. The amount and wavelength of the infrared radiation emitted by an object depends on its temperature, with hotter objects emitting more and shorter-wavelength infrared radiation.

What is mutation ?

Mutation is the change in which there is slight change in the genome sequence of a DNA or RNA along with the gene. The mutation lead to various types to adaptations along with the diseases.        

Resistance is the condition when the species on the multiple exposures develop certain kind of adaptations to it and these traits are sometime inherited sometimes not inherited.

Mutations are friendly as well where sometimes a disease causing mutation can be altered with the further mutation in it.
