Explanation:
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.

The diagram below represents two flies.They look similar but they can not sexually reproduce with each other and produce offspring. This means that the two flies most likely belong to
(1) the same kingdom and same species
(2) the same kingdom, but different species
3) different kingdoms, but same species
(4) different kingdoms and different species (I can't put the picture my bad)
Answer:
(2) the same kingdom, but different species
Explanation:
I believe that they are from the same kingdom (Animalia) but are different species, which causes them to not be able to breed with one another.

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

What is embedded in the phospholipid bilayer that helps in the movement of larger molecules ?
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.
1. Why does the immune system make memory cells?
Answer:
The reason the immune system makes memory cells is to help the body recognize a sickness they have experienced before and react to it.
Explanation:
Which the following takes the most time?
Meiotic prophase II
Mitotic prophase II
Meiotic prophase I
Mitotic prophase I
Option D.
The time required then for the complete process of mitotic cell division would lie within the following limits: Prophase, 30 to 60 minutes; metaphase, 2 to 10 minutes; anaphase 2 to 3 minutes; telophase 3 to 12 minutes and the reconstruction period from 30 t'o 120 minutes: total 70 to 180 minutes.
Meiotic prophase I takes more time than other processes of mitosis or meiosis.
What are the phases of meiosis?Meiosis is a type of reductional division as the chromosome number reduces to half in this type of division. It results in the formation of haploid cells. The process of meiosis takes place in germ cells and gives rise to gametes for sexual reproduction. Each process of meiosis produces four haploid cells.
Meiosis is categorized as meiosis I and meiosis II. Meiosis I gives rise to haploid cells. The prophase I of meiosis I have 5 further stages. These are leptotene, zygotene, pachytene, diplotene and diakinesis.
Meiosis II is comparatively simple and is very much like Mitotic division, except the cells undergoing division are the haploid cells produced by meiosis I. Hence, Meiotic prophase II also takes less time than Meiotic prophase I.
Therefore, the process that takes the most amount of time is the Meiotic prophase I.
