Answer:
Cell Membranes
Phospholipids are amphiphilic, meaning they are both attracted to water in one region of the molecule, and repel water in other regions. The head of the phospholipid molecule is the hydrophilic region. The tails are the hydrophobic region, and point inward, toward each other.
Explanation:
Answer:
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. As shown in the diagram below, each phospholipid molecule has a head and two tails. The head “loves” water (hydrophilic) and the tails “fear” water (hydrophobic).

Question 17 : Describe the features on this map. Where is it steepest? Explain how you can tell that it is the steepest. Which way is the river flowing and how do you know?
Answer:
It is steepest at point B and the river is flowing to the bottom right or southeast of the map.
Explanation:
We can tell that the map is steepest at point B because the lines that display altitude are closest together. Each line indicates 100 miles gained or lost to the overall altitude of the mountain. With the lines closest together, altitude is gained at the most rapid rate, and is therefore the steepest.
Additionally, we can conclude that the river is flowing southeast also because of altitude. The river runs from 1000 altitude to 500 altitude. Since rivers always run downhill, the river will run from the higher northwest point on this map to the much lower southeast point, and is therefore flowing southeast.

What would require more land to grow food crops? If all humans ate only vegetables
or ate only meat. Explain.
Answer:
If all humans ate only meat, will require more land to grow food crops
Explanation:
1) Currently, over 60% of the world food crops are eaten by animals. Given that food crops are generally consumed more than meat in a proportion of 8:1, if all humans ate only meat, the amount of land required to grow food crops will have to be increased by at least 400%
2) Presently, animal agriculture makes use of 70% of lands allocated to agriculture, such that increasing the livestock by an extra 400% will lead to mass deforestation in order to produce livestock feeds
3) It is more costlier to produce livestock than to produce crops, which will make the availability and allocation of land essential for the raising of livestock in order to reduce costs, thereby taking more land.

In cattle, codominance of the allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW); that is, a coat with both red and white hairs.
Cross a roan cow and a roan bull. What are the genotype and phenotype ratios of their offspring?
Answer:
Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)
Phenotype ratio: 1 Red : 2 Roan : 1 White
Explanation:
Codominance is a kind of inheritance pattern in which both alleles are equally dominant in a gene. This means that both alleles when in a heterozygous state will be simultaneously expressed. According to this question, allele for a red coat (R) and the allele for a white coat (W) results in offspring with a roan coat (RW) in cattle.
Hence, in a cross between a a roan cow (RW) and a roan bull (RW), the following gametes will be produced: R and W.
Using these gametes in a punnet square (see attached image), the offsprings with the following genotypes will be produced: RR, RW, RW, WW.
Therefore, based on the results of the cross;
Genotype ratio: 1 (RR) : 2 (RW) : 1 (WW)
Phenotype ratio: 1 Red : 2 Roan : 1 White

how is mitosis related to the cell cycle ?
Answer:
Mitosis is the the point in the cell cycle associated with division or distribution of replicated genetic material to two daughter cells. During mitosis the cell nucleus breaks down and two new, fully functional, nuclei are formed.
Explanation:
Answer:
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.

Athletes training at high altitudes adapt to air with lower oxygen levels than air at sea level. Which cells are most
likely to increase in number as a result of this adaptation?
neurons
red blood cells
white blood cells
muscle cells
Answer:
Red blood cells
Explanation:
Red blood cells are the type of cells that is responsible for carrying oxygen to the cells from lungs and dispose off carbondioxide gas from cells to the lungs. At higher altitudes, the oxygen is present in low concentration so for that purpose more red blood cells are required in order to helps in the delivery of oxygen to the muscles because the athletes needs more oxygen so for fulfill the need for oxygen red blood cells are increases.
