Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?
Answer:
The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.
Explanation:
Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.
Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.
Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.

If mother has type AB Blood and father has A blood type what percentage of their children are likely to have Type A blood?
Answer:
blood with certain proteins clump together when exposed to certain antibodies. A patient has type AB blood. If they received a transfusion of type B blood, predict and explain what would happen. Agglutination would occur because a person with type B blood cannot receive AB blood because they have A antibodies.

5. How is this different from Darwin's idea of fitness?
Answer:
Darwinian fitness differs from the “physical fitness”, which is more associated with health, muscle tissues, oxygen, and physical effort. Darwinian fitness is more concerned about reproductive success. Darwinian fitness describes how successful an organism has been at passing on its genes.
consider the cell labeled x in figure 10-9 containing 4 chromosomes. which of the four cells below it represents a healthy gamete that could be produced from this cell
Answer:
A) A
Explanation:
The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.

A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
There is no mother cell after a paramecium divides because it is divided by binary fission and the paramecium is divided into two identical cells, called daughter cells, there is no mother cell left.
What is paramecium?Paramecium is a protist. It is oval-shaped with cilia all over the body, and it is minute and can be seen only under a microscope. It engulfs its food through the body cavity, which is its mouth.
Binary fission means when the cell is divided into two daughter cells. The division is asexual reproduction. The cell divided DNA into two copies and then each cell gets the DNA.
Thus, there is no mother cell after a paramecium divides since binary fission is used and the paramecium is split into two identical cells, known as daughter cells.

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.
Answer:
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
