The correct answers are:
• Liver cells are abundant in SER.
This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.
• The testes and ovaries are tissue types whose cells are abundant in SER.
This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).
• Cholesterol is made in the SER.
ER is the organelle at which all membrane lipids are synthesized.
• Phospholipids are synthesized from cytosolic water soluble precursor molecules.
Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
Answer: Estivation
Explanation:
Non-mammalian animals that cannot maintain their body temperature by its own. They need to adapt certain phenomenon to survive in the existing conditions.
The animals in the desert like snakes, reptiles, North American tortoise, also maintain their body temperature and maintain an adequate amount of water inside the body.
The animals in the desert do not move out during the daytime in order to conserve water and energy.
This phenomenon is season and is known as estivation.
The geological conditions.
The Structural Organization of
Cells. The cell is the smallest matter that still absorbs the characteristics
of life. All cells have three basic parts, a plasma membrane splits each cell
from the environment, permits the flow of molecules across the membrane, and
consist receptors that can affect the cell’s activities. A DNA-containing
region occupies a portion of the interior. The cytoplasm contains
membrane-bound compartments (except bacteria), particles, and filaments & end
ash; all bathed in a semifluid substance. Eukaryotic cells are defined by their
possession of a membrane-bound nucleus. Prokaryotic cells have no defined
nucleus; the only representatives are bacteria.
