Answer: The type of reproductive barrier represented above is MECHANICAL ISOLATION. The correct option is 1.

Explanation:

Isolation in biology is described as a process by which two species are prevented from copulating( interbreeding) which could lead to production of a hybrid offspring. There are five types of isolation which includes:

- ecological

- temporal

- behavioural

- geographical and

- mechanical isolation.

In mechanical isolation, it occurs due to structural carried that keep species isolated from one another. From the example given in the question, the flowering plant species in which one has a deep flower tube and the other has a short narrow flower tube. The plant with a deep flower doesn't have a correct shape (structural barrier) for the pollinator ( honey bee( therefore won't receive a pollen transfer by it. Likewise the short narrow flower tube plant, doesn't have a correct shape for the pollinator( bumblebee) and therefore won't receive a pollen transfer. I hope this helps, thanks.

What is true of carbon atoms? (2 points)
Rudiy27
By process of elimination you can find the right answer. We know for a fact that carbon is found in all living organisms. That is why we talk about carbon based life forms. So the first statement cannot be true. You can figure out how many Valence electrons an element has by looking at the group number. The group number of carbon is 4 so the 2nd statement cannot be true. We know that carbon does bond with other elements because it is not a noble gas and therefore must be able to form compounds.
This means the answer must be they can form up to four covalent bonds

The ________ division of the autonomic nervous system is often called the "rest-and-digest" division.
Ad libitum [116K]

Answer:

Parasympathetic nervous division

Explanation:

The parasympathetic division of nerves is a part of the autonomic nervous system which gets activated during the relax conditions.

The parasympathetic nervous system is the opposite of the sympathetic nervous system which gets activated during the stress condition.

The parasympathetic division gets activated when the level of cortisol and adrenaline gets decreased and the body responds by detoxifying, digesting and building immunity.

Thus, Parasympathetic nervous division is the correct answer.
