Answer:
Aquaporins
Explanation:
Aquaporins are the channel proteins that is present in the membrane of the cell which allow water to cross the membrane very quickly. This aquaporins play an important roles in plant cells, red blood cells, and certain parts of the kidney where this protein minimize the amount of water lost as urine. Without this protein, the diffusion of water across the cell membrane is not possible very quickly.
This is a product of meiosis

Logically, the cell would have two nuclei because karyokinesis (the division of the nucleus) occurs before cytokinesis (division of the cytoplasm).
Living things differences are important because it helps classify and signify one from another
<h3><u>Comparison between Galapagos penguin and cold adapted Emperor penguin of Antarctica:</u></h3>
<u>Galapagos penguin:</u>
- Galapagos penguins are the only species of penguins that live north of the Equator.
- The Galapagos penguins breed all-round the year.
- The Galapagos penguins are smaller compared to the cold-adapted emperor penguins of Antarctica.
- The breeding and nesting place of the Galapagos penguins lie on the shoreline.
<u>Emperor penguin:</u>
- The emperor penguins live and adapt to the cold Antarctic environment.
- The Emperor penguins breed only during the Antarctic winters.
- The nesting of emperor penguins is on ice cliffs and icebergs where the eggs are protected from the strong and cold Antarctic winds.
- However, both of these species of penguins are at risk of extinction due to the rise in temperature and shortage of foods.
