how does sexual reproduction increase variation within a species
Explanation:
The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. ... A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.
Answer:
because it increases the gene pool
Explanation:
So sexual reproduction requires two organisms, a male and a female, and their offspring has a combination of both of the parents, this varies the gene pool. Then the offspring creates more offspring, further varying the gene pool.

A.Channel/Transport proteins
B.Salt
C.Water
D.Fats
Answer:
[tex]\boxed {\boxed {\sf A. \ Channel/Transport \ proteins}}[/tex]
Explanation:
The phospholipid bilayer is also known as the cell membrane. It covers cells and regulates the transport of substances. Certain ones can pass and others cannot, depending on certain factors like size and polarity.
Smaller substances tend to diffuse or move across the membrane quite easily. However, larger molecules have a much harder time. Many depend on special proteins embedded in the membrane. These are called transport proteins and they form a channel so large molecules can still move in or out of the cell.
So, salt, water, and fats do not contribute to the movement of larger molecules, but channel or transport proteins do and choice A is correct.
Where does the light and thermal energy given off when burns food come from?
A Light and thermal energy given off from burning food comes from the lighter used to light the food.
B. Light and thermal energy given off from burning food is converted from the chemical energy stored in
the food.
C. Light and thermal energy given off from burning food comes from oxygen.
D. Light and thermal energy given off from burning is created when food burns.
3. Why do two grams of fat provide a different amount of energy than two grams of carbohydrate?
Answer: B
Explanation: Because Light and thermal are two different things of heat and if one of the cores of heat gets any cooler than it is than it may burn out and there wwill no longer be heat so the food brin come in at the middle (Core) of the heat and just like a microwave it had different heats but its core of the heat stays the excact same
