4. What genotypes of parents will have only white-fur offspring? Parent 1 genotype = Parent 2 genotype = What genotypes of paren

AnnZ [28]

Answer:

All white offspring: Parent 1 genotype = homozygous dominant

Parent 2 genotype = homozygous/heterozygous dominant

For all black offspring: Parent 1 genotype = homozygous recessive

Parent 2 genotype = homozygous recessive

Explanation:

The cross was between a white mouse and a black mouse and the phenotypic ratio of the resulting offspring is 50% white and 50% black.

Assuming that fur color in the mouse is represented by the allele A (a), In order to give 1:1 phenotypic ratio of the offspring, it means the white mouse is heterozygous with Aa genotype and the black mouse is homozygous with aa genotype. Also, it means that the allele A is dominant over the allele a.

Aa x aa

Aa Aa aa aa

Aa = white

aa = black

Ratio of white to black = 50/50 or 1:1

Hence, in order for a cross to yield only white offspring, the parents can either be homozygous AA and AA or one will be homozygous AA and the other will be heterozygous Aa.

1. AA x AA

AA AA AA AA (all white offspring)

2. AA x Aa

AA Aa AA Aa (all white offspring).

In order to produce only black offspring, both parents must be homozygous aa.

aa x aa

aa aa aa aa (all black offspring)

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach

RUDIKE [14]

Answer:

The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.

It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.

If the problem lies in the stomach it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.

Explain sources of error.

LekaFEV [45]

Answer:

Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig

The gaps of unjoined membrane through which small molecules exit and enter capillaries are called __________.

Dafna1 [17]

Answer:

Explanation:

1. A channel between two adjacent cells in known as an intercellular cleft.

2. And through these channels many molecules can easily pass between cells.

3. Importance of Intercellular clefts:

i) It is very important in transportation of fluids and small solutes.

ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
