A. ANL/ANL, YGR/YGR for parent 1, and anl/anl, ygr/ygr for parent 2.
B. ANL/anl, YGR/ygr for parent 1, and ANL/anl, YGR/ygr for parent 2.
C. ANL/anl, YGR/ygr for parent 1, and anl/anl, ygr/ygr for parent 2.

Answers
Answer:
C
Explanation:
The data shows that each phenotype occurs about one-fourth of the time. That means that there are about equal numbers of purple-stemmed and green-stemmed plants, and about equal numbers of green-leaf and yellow-leaf plants. Of the four choices, answer A can be eliminated because all of the offspring of an ANL/ANL plant will have purple stems. Answer D can be eliminated because all of the offspring of two anl/anl parents will have green stems.

pls help how do i compare the aspect of an autograft to that of an allograft
Answers
Answer:
The correct answer is - A patient's own tissue - an autograft and tissue from another person - an Allograft.
Explanation:
If the bone or the tissue is transferred from one point of the body to another point of the same person's body, this is called an autograft and is also thought of as "gold standard". It has a low level of risk in comparison to other grafts. It is used for surgical reconstruction.
An allograft is the transfer of the tissues or bone of an individual to the body of another individual of the same species during the surgical process. This type of graft has some risk of compatiblity.

What are the genotypes of the parents?
Question 5 options:
bb and bb
BB and bb
Bb and Bb
BB and BB
Answers
Answer:
BB and BB
Explanation:
BB is a homo-zygous allele and both of the parent guinea pigs are homo-zygous.
A black coat is dominant over a white coat in guinea pigs. The genotypes of the parents are BB and BB. The correct option is d.
What is a genotype?The terms genotype and phenotype relate to the individual's alleles and the observable traits that are generated from the genotype and determined by the dominance of the alleles, respectively.
For black coat = B
For White coat = b
A homozygous black pig is mated with another homozygous black pig. Homozygous means only one character will be shown in the genotype, that is the dominant and the dominant trait is black, B so, the genotype will be BB and BB. Recessive traits are hidden that do not show, and that is also black.
Therefore, the correct option is d. BB and BB.

Describe how the process of apoptosis occurs?
Answers
Answer:
Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
What is apoptosis ?It is a natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.
There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.
Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.
Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated Bax, and Bcl-2 molecules.
Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

A. Wires made of conductors have high
resistance.
B. Wires made of conductors have greater
resistance.
C. Wires made of conductors have low
resistance.
Answers
Wires made of conductors have low resistance. The correct option is C.
What is a conductor?Conductors are materials that allow the flow of through them. Insulators are those materials that prevent electricity from passing through them.
Copper, aluminum, gold, and silver are a few examples of common conductors. Wood, rubber, plastic, and glass are a few typical insulators.
A conductor is an object or kind of material that permits the movement of charge (electric current) in one or more directions.
This term is used in both physics and electrical engineering. Metal-based materials are frequently used as electrical conductors.
Low resistance to the flow of electricity is provided by good conductors like copper, aluminum, etc. They do so because they have a lot of free electrons.
There are no free electrons in insulators. As a result, despite applying voltage across them, essentially no electric current flows through them.
Thus, the correct option is C.

lipid production; increases in liver cells as a response to regular alcohol or barbiturate consumption
Answers
Answer: Lipid production occurs at slower rate.
Explanation:
The ethanol or ethyl alcohol is a hepatotoxic which involves the redox changes in the NADH that results due to the oxidation of the alcohol dehydrogenase enzyme. It affects the metabolism of the lipids, amino acids, carbohydrates and proteins in the body. As the liver cells get engaged in metabolism of regular alcohol or barbiturate. The liver cells get damaged in this process. The ethanol is metabolized into acetaldehyde. So, the lipid production as a metabolite occurs at a slower rate.
