Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?

Answers

Answer:

3/16

Explanation:

This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).

In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:

9/16 of Round, yellow offsprings (R_Y_)

3/16 of Round, green offsprings (R_yy)

3/16 of Wrinkled, yellow offsprings (rrY_)

1/16 of wrinkled, yellow offsprings (rryy)

Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

Which of the following statements describes the structure of the plasma membrane?
a It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.
b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.

Answers

Answer:

A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.

Explanation:

The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.

Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.  

This is why option A is the correct one.

You can see an image of the cell membrane's structure to help you visualize this below:

What is the first step of DNA replication?

A. Free nucleotides bond together in the correct sequence.

B. A single-stranded RNA molecule forms.

C. The DNA transfers its information to RNA through an amino acid.

D. The DNA molecule unzips along weak hydrogen bonds.

Answers

Answer:

D

Explanation:

The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule. This is carried out by an enzyme, called helicase which breaks the hydrogen bonds? holding the complementary bases of DNA together

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. The option (D) is correct.


What is DNA replication?

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.

Moreover, DNA must replicate (copy) itself so that each resulting cell after mitosis and cell division has the same DNA as the parent cell. All these cells, the parent cell and the two new daughter cells, are genetically identical.

Therefore, DNA replication is the process of creating two identical daughter strands of DNA. DNA replication occurs in the nucleus in eukaryotic cells and in the nucleoid region in prokaryotic cells. DNA replication occurs in S phase during the cell cycle prior to cell division.

What happens during the first two stages of cellular respiration?

Answers

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
