Why are silent mutations possible for some of the amino acids?

Answers

Answer:

That's possible because proteins are encoded by "triplets" of nucleotides, each responsible for adding a particular amino acid to the protein chain. A change in one nucleotide, however, doesn't always change the triplet's meaning; the mutated triplet may still add the same amino acid.

Cory states the following argument about the evolution of aardvarks and anteaters.

"Aardvarks and anteaters both use long, sticky tongues to capture and eat ants or termites. Aardvarks are native to Africa, while anteaters are native to the Americas. However, their similarities provide evidence that both groups of species evolved from a common ancestor that used its tongue to eat ant-like insects."

Which claim, if supported by evidence, would provide the strongest counter-argument AGAINST Cory's argument?
A. The tongues and diet of aardvarks and anteaters are an example of convergent evolution.
B. The tongues and diet of aardvarks and anteaters are an example of adaptive radiation.
C. The Americas and Africa were once joined together, and animals roamed freely between the two lands.
D. A long, sticky tongue evolved in response to the tunneling behavior of ants, an example of coevolution.

Describe an experiment used to prove that amino acids and sucrose go up and down the phloem.​

Answers

Answer:

By using carbon-14 in the experiment in order to prove the statement.

Explanation:

Translocation occurs in the plant body in order to transport amino acids and sucrose from one part to another by the phloem tissues. In order to prove this, we have to incorporate radioactive element in the amino acid or sucrose which shows us that through which layer the amino acids and sucrose move in the plant body. For this purpose, carbon-14 can be used to trace the path of the translocation of amino acids and sucrose. Through this experiment we will find out that phloem layer is the path used by the plant to move amino acids and sucrose from one part to another.

If data for the growth of this bacterial population continued to be recorded, would the data point at 60 hours be above or below 37 million? Support your answer.

Answers

Answer:

Above 37 million

Explanation:

Explanation in picture below

Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

Thus, Bacterial population growth occurs geometrically or exponentially: in  each division cycle (generation), one cell produces 2 cells, then 4 cells, then 8 cells, then 16, then 32, etc.

The relationship shows that the average generation time is constant and  the growth rate of the bacterial population is proportional to the number of bacteria at any given time.

This relationship is valid only during the period when the population grows exponentially, ie. in  the logarithmic phase of growth. Therefore, graphs showing the growth of bacterial cultures are plotted as the logarithm of the number of cells.

Thus, Growth of bacterial cultures is defined as an increase in the number of bacteria in a population rather than an increase in the size of individual cells.

What is Mating?

For the goal of sexual reproduction, opposite-sex or hermaphrodite organisms team together during mating. Two gametes join together during fertilisation. When two sexually reproducing creatures join their sex organs, internal fertilizations and insemination take place.

Punnett Square situations with two hybrid parents marrying are frequent. The heterozygous hybrid parents possess a single allele (A and a, Dominant and Recessive). There are four genotype outcomes that can happen if two hybrid parents mate.

Thus, when two-hybrid Ff rabbits mate, then the offspring look like

A) nuclear

B) coal

C) natural gas

D) biofuels

Answers

Answer:

The correct answer is - A) nuclear.

Explanation:

Most of the non-renewable sources of energy are fossil fuels that are formed by the thermal decomposition of dead organic matter for million years and are converted to lighter hydrocarbons that contain high electrostatic potential energy.

Burning is the process that breaks the hydrocarbons into water vapor and CO2 with high amount of energy. Coal, natural gas and biofuels all three are fossil fuels and nuclear products are not fossil fuel but radioactive elements.

Answer:

No.

Explanation:

Turns out they have yellow peas because the yellow version, Y, is dominant over the recessive green version, y. Y always wins out over y: When a pea plant makes seeds, only one of its two copies of the color gene goes into the seed. So if you have two green pea plants, each can only pass a green version.
