Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.

The sucrose move in source to sieve by active transport.
<h3>What is active transport?</h3>
Active transport is a type of transport in which the cell expends energy to move solutes against their concentration gradients. The sodium-potassium pump is an example of active transport. Active transport differs from passive transport in that the cell does not expend energy.
In this case, the sucrose moves from companion cells into source to sieve elements by active transport. This reduces the water potential of the source to sieve element by osmosis, which increases the hydrostatic pressure.

Answer:
The answer to your question is: D. Binary fission
Explanation:
A. Mitosis This is the process by which somatic cell divide, from 1 cell the result is 2 cells.
B. Meiosis This is process by which reproductive cells divide, the product of this process is 4 daughter cells.
C. Conjugation is a process by which bacteria transfer DNA to another cell but is not a process of division.
D. Binary fission , this is the process by which Bacteria reproduce, the result of the mechanism is 2 identical daughter cells.
Answer:
These are needed to mimic the blood vessels which these organs will use for the supply or drainage of fluids e.g blood.
In addition the empty tunnels serve as the routes for nutrients and oxygen supply for the organ.
In summary the tunnels provided a vascular structure to support the organ
