Infer why base substitutions in the third position are least likely to cause a change in the amino acid for which it coded.

Answers

Answer:

Because of the codon oscillation.

Explanation:

The formation of codons is susceptible to the occurrence of oscillation, which is the term that corresponds to the fact that many codons have synonyms in the third position, that is, in the third letter. For example, the codon CUA, which represents leucine, will also represent leucine if it is presented in CUU, CUC and CUG forms, due to the oscillation in the third position. This allows the tRNA to recognize any of these codons and pair with the anticodon smoothly and without errors.

Which statement describes only biotic factors in a forest ecosystem?

Answers

Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks and water.

Answer:

A bird and a squirrel are living in a tree.

Explanation:

Competition for food is an example of a biotic factor in an ecosystem. A red squirrel and a grey squirrel living in the same habitat will compete for the same food source. 2. Predator-prey relationships are examples of biotic factors.


What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m

Answers

Answer:

length of base(l) = 14m

slant height (s)=25m

we know,

slant height(s)=√(l/2)^2 + h^2

or, 25= √(14/2)^2+ h^2

or, 25 = √49+h^2

or, 25^2 = 49+h^2

or, 625 = 49 + h^2

or, 625-49=h^2

or, √576 =h

h=24

Therefore vertical height (h)= 24m

Again,

Volume of square pyramid (v) = 1/3 L^2h

or, v =( 1/3) 14^2×24

or, v= 4704 / 3

Therefore, V= 1568 cubic meter.

(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.

Answers

Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.

A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.

Answers

Answer:

Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.

The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

Answer:

1. Tissues

2. Heterotrophic

3. Body cavity

4. Eukaryotes

5. Radial symmetry; bilateral symmetry.

Explanation:

1. All animals except sponges have tissues, groups of cells that work together to perform a specific function.

Sponges are sea animals which are found attached to surfaces. They are multicellular and heterotrophic like other animals, but they lack true tissues and organs.

2. All animals eat other organisms in order to gain building materials for the body. This makes them heterotrophic, since they obtain necessary energy and chemical building blocks from the environment.

Heterotrophs are organisms that cannot manufacture their own food, but obtain it from their environment instead.

3. One key adaptation of animals was the evolution of a body cavity, a fluid-filled gap between the outer wall of the body and the outer wall of the digestive system.

A body cavity is a space found inside the body that is filled with fluid and which holds and protects internal organs. There are several cavities found in the human body and they are separated by membranes as well as many other structures.

4. All animals are eukaryotes, organisms with cells that are relatively large, complex, and contain membrane-enclosed organelles such as the nucleus.

5. Cnidarians are the only animal phylum to display radial symmetry, meaning that their bodies can be divided any way through the center point to yield two even halves.All other adult animals display bilateral symmetry, meaning that their bodies can only be sliced lengthwise through the midline to produce two even halves.

⦁ Arrange these statements in the right order to describe process of inhalation.

____ Air is drawn into the lungs
____ Air pressure in the chest cavity decreases
____ Lungs expand
____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out

Answers

Answer:

air is drawn into the lungs

lungs expand

the muscles between the ribs contract to move the ribs up and down

air pressure in the chest cavity decreases

the diaphragm contracts and flattens

Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.

What is inhalation?

Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.

This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.

Therefore, the air is drawn inside the lungs in inhalation.

A. irregular
B. stable
C. irruptive
D. cyclical

Answers

B. because irruptive is when the growth goes up and cyclical is when the growth continuously keeps changing

When there is no pattern to a population's growth, it is known as stable. The correct option is B.

What is population growth?

The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.

The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.

When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.

Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.

Thus, the correct option is B.
