Answer:
Reproductive cells are called: Gametes.
Female Reproductive cells: Egg.
Male reproductive cells: Sperm.
Explanation:
In sexual reproduction each sex has 2 reproductive cells, the egg and the sperm. Sperm fertilizes the egg and the egg will now grow into an embryo. As a whole those two cells are called gametes but depending on gender they have different names.
Hi, In my opinion, <u>bat</u> will be the most closely related to hawk.
<h2>
Why?</h2>
This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-
• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.
• Presence of small snouted beak-like structure and presence of less or more similar color.
• Both live in trees and are normally not companiable with humans.
• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.
• They have the sense of locating prey miles away, enabling easier locating of food.
Hope this helps...

The endosymbiotic theory states that eukaryotic cells might have evolved from prokaryotic cells through a close realtionship.
Answer:
Hydrophilic heads facing exterior
Hydrophobic tails facing interior
Explanation:
In 1972, the fluid mosaic model was proposed to describe the structure of the plasma membrane. This model describes the plasma membrane to possess components including phospholipids, cholesterol and proteins. The phospholipid component is composed of glycerol, two fatty acids and a phosphate-containing head, which are arranged in two adjacent layers forming the phospholipid bilayer in the membrane of biological organisms.
Phospholipids have both the hydrophilic and hydrophobic region. Hence they are said to be AMPHIPATHIC.
The head of the phospholipid is negatively charged due to its phosphate content, making it polar and hydrophilic i.e. water-loving. This hydrophilic head faces the exterior of the cell in order to interact with fluids.
The tails of the phospholipid are long fatty acids that keep away from water i.e. hydrophobic. Due to their water-fearing nature, they avoid water and face the interior of the cell, where each tail face each other.
