In the space below, summarize the process of sexual reproduction in unicorns to explain how offspring are produced. Include and highlight the following terms in your summary: Diploid, Fertilization, Gametes, Haploid, Interphase, Meiosis
Answer:Sexual reproduction allows some of the genetic information from each parent to mix, producing offspring that resemble their parents but are not identical to them. In this way, sexual reproduction leads to variety in the offspring. Animals and plants can reproduce using sexual reproduction.
Why do the chromosomes line up in the middle of the cell
Answer:
QUESTION:
Why do the chromosomes line up in the middle of the cell?
ANSWER:
Chromosomes line up at the metaphase plate, under tension from the mitotic spindle. The two sister chromatids of each chromosome are captured by microtubules from opposite spindle poles. In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
Explanation:
Hope that this helps you out! :)

Explanation:
If a myostatin protein is not the right shape, it cannot fit correctly into a cells receptor true or false
Explanation: Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a myokine, a protein produced and released by myocytes that acts on muscle cells to inhibit muscle cell growth. In humans it is encoded by the MSTN gene.[6] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family.[7][8]
Therefore, if the myostatin protein is smaller than a microorganism it would be able to fit into the receptor.

Mitosis and meiosis are important parts of cellular reproduction. Select all the correct statements
about MEIOSIS.
Creates genetic variation
Produces gametes
Produces two daughter cells
Creates four, haploid daughter cells
Answer:
A is correct
B is correct
C is INcorrect
D is correct
Explanation:
Since there are two parents with different genes that produce new cells, and the fact that chromeosomal crossover accures very commonly in meiosis, there is genetic variation. So A is correct.
B is correct since gamates are haploid cells.
As I said above, gametes are haploid cells, not diploid. MITOSIS produces two identical daughter cells, known as diploid cells. This is not meisosis, which produces four haploid cells. So, C is incorrect since that is talking about MITOSIS. But knowing this, D must be correct since that is about meisois.

Answer:
D. Agricultural runoff
Explanation:
explain why aerobic respiration occurs before lactic acid fermentation in most muscles.
Aerobic respiration occurs when there is insufficient oxygen is present in respiration. If the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration.
Aerobic respiration:Aerobic respiration occurs in the cell of the body.It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food.Water and carbon dioxide are produced as end products.Thus, we can conclude that aerobic respiration occurs when there is insufficient oxygen present for respiration. if the body does not respire enough, the cells respire anaerobically. During vigorous exercise, muscle cramp occurs due to the production of lactic acid by anaerobic respiration. The acid wears away muscles and causes cramps.

Explain how cellular respiration is important for the production of ATP build on aerobic vs anaerobic
Answer and Explanation:
ATP is the energy molecule of the organism, being necessary for all cellular processes. It is produced in both aerobic and anaerobic respiration, but the processes are different.
Aerobic respiration, ATP is produced by breaking down the glucose molecule found in the food we consume. This process occurs in all organisms that need the presence of oxygen to survive. However, this is a complex process that occurs with the help of several enzymes and co-enzymes that perform various oxidation reactions on the glucose molecule, transforming it into carbon dioxide, water and ATP.
Anaerobic respiration is also known as fermentation and occurs in all organisms that cannot survive in the presence of oxygen. This process also occurs with the help of enzymes and coezimas, where the glucose molecule is degraded until it becomes two molecules of pyruvate. During the pyruvate degradation reactions, an ADP molecule is released, which will later be added to a phosphate molecule that is free in the cytosol, becoming ATP.
