The two species of snakes, the Emerald Tree Boa and the Boa Constrictor, belong to the same genus; however, the former is tree dwelling and needs high humidity whereas the latter is terrestrial and requires a dry environment. What kind of the evolutionary mechanism was responsible for this?. A. Allopatric evolution. B. Sympatric evolution. C. Convergent evolution

Answers

Answer 1

Answer: B. Sympatric evolution. is responsible to this. It's the process of evolving species from one shared ancestor in the same geographic region.

Answer 2

Answer:

Answer:

The kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.

Explanation:

We need to study two species of snakes, the Emerald Tree Bow and the Boa Constrictor, they belong to the same genus. However, the former is tree-dwelling and needs high humidity whereas the latter is terrestrial and requires a dry environment.

To explain this phenomenon we present a similar example: Imagine that your family has lived in the same house for many years. After that, imagine that your sister moves out of that house and into a house in a nearby neighborhood. She begins a new family there and, through the years, her family continues to grow and live in this new house. When your family separated, you became different groups of people from the same common ancestor. Eventually, you might even evolve enough to feel that there are more differences between you than similarities. When this happens in nature, it's called sympatric speciation. This process allows new species to evolve from a common ancestor, while the new and old species are still living in the same geographic region.

This example is almost the same as both snakes. Sympatric Evolution was responsible for this phenomenon.

Finally, we can conclude that the kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.

Veins contain a network of valves to insure a one-way flow of blood but arteries do not. This is because veins must counteract the force of _______ on blood flow

Answers

The answer is Gravity. To ensure the one-way flow of blood the veins contain a network of valves which arteries do not have. The reason is for the veins to counteract the force of gravity on flow of blood. For example, to increase the pressure of the blood back to the heart the veins must counteract the force of the gravity.

Answer: A) gravity

the answer to the question is genetic science

If a plant has a mutation and cannot produce Casparian strips, what process won't it be able to do?

Answers

If a plant has no Casparian strips, it will not be able to control the amount of water it absorbs and solutes. Casparian strips regulate the amount of water that gets to the xylem. Without it, a plant won’t be able to control the amount of water going to the xylem.

If a plant has a mutation and cannot produce casparian strips, the process that it will not be able to do is to control the amounts of water and solutes it absorbs. These casparian strips are found in the roots of plants.

The following are 1.0 M acid solution, which has the largest concentration of hydronium [H3O+]?A. HNO2

B. H2CO3

C. H2SO4

D. H3BO3

Answers

H2SO4 has the largest concentration of hydronium [H3O+] because H2SO4 is a strong acid.

Answer: Option (C) is the correct answer.

Explanation:

An acid which is able to dissociate completely into ions in water is known as a strong acid.

For example, $H_(2)SO_(4) \rightleftharpoons 2H^(+) + SO^(2-)_(4)$

Therefore, sulfuric acid is a strong acid as it dissociates completely into ions in water.

Whereas $HNO_(2)$ , $H_(2)CO_(3)$ , and $H_(3)BO_(3)$ are all weak acids as they dissociates slightly in water as follows.

$H_(3)BO_(3) \rightleftharpoons H^(+) + H_(2)BO^(-)_(3)$

$HNO_(2) \rightleftharpoons H^(+) + NO^(-)_(2)$

$H_(2)CO_(3) \rightleftharpoons H^(+) + H_(2)CO^(2-)_(3)$

Morover, sufuric acid upon dissociation is giving 2 hydrogen ions and rest all are giving one hydrogen ion.

Thus, we can conclude that out of the given options $H_(2)SO_(4)$ has the largest concentration of hydronium [H3O+].
