Answer:

Punnett square is a square diagram which is used to predict the genotype of the offspring produced by particular cross.

Let P and p be the alleles of the gene responsible for the flower colors in a plant.

The genotype of both the parents is given as heterozygous that is, Pp.

Two types of gametes would be formed P and p.

The cross is shown in the image below.

The cross would be result in offspring with three types of genotypes PP, Pp and pp in 1:2:1.

The diagram below represents levels of organization in living things. Which term would best represent X?
Nutka1998 [239]

The correct answer is C. Tissue

Explanation:

In the diagram, x is between organ and cell level. This implies this level of organization is smaller than an organ but no as small as one cell. In this context, the most suitable term to add to this level is a tissue because these are structures composed of specialized cells, which shows this level encloses cells. Also, a group of tissues forms an organ; this implies the organ is the level that follows the tissue. Examples of this include muscle tissue composed of muscle cells and that is part of organs including the heart.

Assume that there are 8 rats in the cage: 6 trained and 2 untrained. A rat is removed from the cage and it is noted whether or n
mojhsa [17]

Answer:

1. Option A

2. 56

Explanation:

1.

Option A

Option A is not a valid answer for this question as it is given that out of eight rats only two rats are untrained. Thus, an output which shows more that two untrained rats i.s UUTTU is a wrong answer

2.

8C_5 = \frac{8!}{5!(8-5)!} \\8C_5 = \frac{8*7*6*5!}{5! * 3!} \\8C_5 = \frac{8*7*6}{3*2*1} \\8C_5 = 56

Thus , there are 56 outcomes possible for this experiment

Glycolysis Shortcut Suppose you discovered a mutant yeast whose glycolytic pathway was shorter because of the presence of a new
zubka84 [21]

Answer:

No.

Explanation:

As you may already know, glycolysis is an anaerobic metabolic pathway, that is, without the presence of oxygen, which is able to break down glycolysis into smaller molecules that are capable of providing energy (ATP) to living beings after a series coordinated and indispensable reactions.

In the question above, we can see that a cinetist discovered a mutant yeast that was able to perform glycolysis more quickly due to the presence of a certain enzyme. If we analyze the reaction that this enzyme is capable of generating, we can conclude that the shortening of glycolysis is not beneficial to the cell. This is because the amount of ATP produced anaerobically, by glycolysis, would be non-existent. Aerobic ATP production would also be affected, but on a small scale.

When two plants, both tall, were crossed, they produced some offspring that were dwarves. Assuming that the height of the plant
Strike441 [17]
T- tall allele
t- dwarf allele

This cross needs to be between 2 plants with the same genotype, like Tt xTt

In this cross it would result in:
 1/4 of the plants being tall homozygote- TT
2/4 of the plants being tall heterozygote- Tt
1/4 of the plants being dwarfs homozygote- tt
