In rats, gene B produces black coat color if the genotype is B–, but black pigment is not produced if the genotype is bb. At an independent locus, gene D produces yellow pigment if the genotype is D–, but no pigment is produced when the genotype is dd. Production of both pigments results in brown coat color. If neither pigment is produced, coat color is cream. Determine the genotypes of parents of litters with the following phenotype distributions. Part A 4 brown, 4 black, 4 yellow, 4 cream
Answers
Answer:
Bbdd and bbDd
Explanation:
From the illustration:
B_dd - black color
bbD_ - yellow color
B_D_ - brown color
bbdd - cream color
In order to produce litters in the ratio 4 brown, 4 black, 4 yellow, and 4 cream; the genotypes of the parents must be Bbdd and bbDd. The cross between the two parents would be such that:
Bbdd x bbDd
4 BbDd - brown color
4 bbDd - yellow color
4 Bbdd - black color
4 bbdd - cream color
See the attached image for the Punnet's square analysis of the cross.

What are some methods scientists have discovered that can stop a virus from spreading in its host? (Choose all that apply)
destroy the RNA polymerase altogether
prohibit the RNA polymerase from starting initiation
stop the RNA polymerase from moving along the DNA strand.
use antibiotics to destroy the RNA polymerase before initiation
Answers
Answer:
destroy the RNA polymerase altogether
prohibit the RNA polymerase from starting initiation
stop the RNA polymerase from moving along the DNA strand.
These are the correct answers
Explanation:
A virus can be stopped from spreading in its host by destroying the RNA polymerase altogether, Prohibition so the RNA polymerase from the starting initiation, and by stopping the RNA polymerase from moving along the DNA strand. Thus, the correct options are A, B, and C.
What is a Virus?A virus is a sub-microscopic organism, which is an infectious agent that replicates only when present inside the living cells of an organism by using its replication machinery. Viruses infect all the life forms, from animals and plants to the microorganisms, such as bacteria and archaea.
Viruses can be stopped from spreading in the host body by destroying the RNA polymerase, this RNA polymerase is responsible for the multiplication of RNA from host DNA in an organism. By prohibiting the activity of RNA polymerase from initiating the replication the multiplication of viruses can be stopped. This RNA polymerase moves along the host DNA and forms new strands for the replication purpose.
Therefore, A, B, and C all are correct options.

Which planet is most similar in temperature to Earth?
Answers
Answer:
It depends; If you're asking for very temporary moments on the planet, it would be mercury, because its temperature ranges from 427 degrees to -180 degrees Celcius. If you were to stand just in the right spot at just the right time, its temperature would be the same as the earth's temperature.
But if you are asking about longer periods of time, it would be Mars. Its average temperature is around -60 degrees celcius, but its summer can get up to 20 degrees celcius.

This monarch butterfly has orange wings. Is orange
the genotype or the phenotype? Explain
Answers
Answer:
Phenotype
Explanation:
It's phenotype because a genotype is not a physical trait; a genotype means genes. It's phenotype because it a physical trait you can see. Lets say twins look the same on the outside but on the inside they have completely DNA. This is like how some butterflies look the same with orange wings but one might have a mutation in its genes.

Which best describes the nucleus of an atom?
a. It is thee negatively charged part of the atom
b. It contains no mass.
c. it is made of neutrons and electrons.
d. It is the most massive part of the atom
Answers
Answer:
The answer is D.
I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!
Explanation:
So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.

Which of the following happens when a phosphate-phosphate bond in an ATP molecule
is broken?
Lysosome contents are released in a cell.
Energy is released in a cell.
Water is transported into an animal cell
Light energy is absorbed in a plant cell.
Answers
Answer:
An event that occurs when a phosphate-phosphate bond is broken in ATP is that energy is released in a cell.
Explanation:
Adenosine triphosphate or ATP is the molecule in charge of providing energy to the cell, which is necessary to perform its functions.
The energy contained in ATP depends on the high-energy bonds that bind the phosphate groups to the energetic nucleotide molecule. Through the hydrolysis of ATP, phosphate is separated from ATP, obtaining ADP, and a large amount of energy is released. This energy serves for the cell to perform its metabolic functions.
The other options are not correct because:
Lysosomes act on cellular digestion. Transport of water into the cell occurs by osmosis, through aquaporins. Light energy is absorbed in a plant cell, through photosynthesis.
