Answer:
The correct answer would be active transport by proteins.
When a molecule is transported against the concentration gradient it requires cellular energy and the process is termed as active transport.
The energy is either provided by the hydrolysis of the ATP (adenosine triphosphate) in primary active transport or by the electrochemical gradient in secondary active transport
Active transport takes place with the help of integral membrane proteins or transport proteins which form carriers or channels across the membrane.
Examples may include a sodium-potassium pump, uptake of glucose in small intestine et cetera.
An approach to systematics in which organisms are placed into groups called clades based primarily on common descent. A group of species that includes an ancestral species and all its descendants. Pertaining to a group of taxa that consists of a common ancestor and all of its descendants. It is equivalent to a clade.

<h3><u>Answer</u>;</h3>
- It can form polymers like carbohydrates, lipids, proteins, and nucleic acids.
- It can regulate temperature.
- Decomposition of molecules can occur readily, releasing needed energy.
<h3><u>Explanation</u>; </h3><h3 />
- Carbon has an exceptional ability to bind with a wide variety of other elements.
- C<u>arbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen.</u>
- Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms.
Answer:
Vanilla
Explanation:
Sometimes that manual labor shows up in the price of the food; sometimes it doesn't ... We thought there would be an easy answer to that, but there isn't. ... This spice is among the most expensive in the world; the biggest producers are Italy, Iran and Spain ... Those forces combine to lead to the labor issues.
