Answer:
Active transport
Explanation:
The process of transport of substances that uses energy and carrier proteins of the membrane is called active transport. Amino acids can not cross the hydrophobic core of the membrane and therefore, are transported through carrier proteins. The carrier proteins transport the amino acids using energy and the process is called active transport.
Answer:
Analogous structures
Explanation:
These structures are similar but not derived from the common ancestor like homologous structures. Analogous structures are formed as a result of convergent evolution-type of evolution in which organisms develop on similar way but independently. An example of analogous structures are wings. Birds, insects and bats all have wings, with the same purpose (flight) but they evolved in their own way.
One is wider because it is colder on the moon than earth and is harder to warm up due to it. Two is never because in order to have a thunderstorm you need to have water evaporated and condensed into cumulonimbus clouds, which cannot happen somewhere with no water.
It is d, a substance that participates in a chemical reaction. You can also tell it just by looking at the stem of the term :)
