If a corn plant has a genotype of Ttyy, what are the possible genetic combinations that could be present in a single grain of pollen from this plant

Answers

Answer 1

Answer:

Ty and ty

Explanation:

This corn plant is being observed based on two traits controlled by two different genes (t and y). According to Mendel's law of independent assortment, the alleles of each gene of this corn plant will undergo segregation into gametes independently of one another. Hence, four possible combinations of gametes (present in the pollen) will be produced by this corn plant since it involves two traits/characters i.e. 2^n which n is the number of traits 2^2=4.

Hence, the four possible combinations of gametes that can be produced by a corn plant with Ttyy genotype is Ty, Ty, ty and ty.

Ty and ty are the only two distinct combinations

Answer 2

Answer: The two combinations possible are Ty and ty. The allele Y doesn't exist in it's genotype, it cannot pass on the dominant allele Y, because it can't pass on what it doesn't have.

Explanation:

Which of the following is a result of a change in pressure?a. Frost wedging
b. Oxidation
c. Exfoliation
d. Chemical feathering

Answers

The answer is C. The type of weathering that occurs due to changes in pressure drop is a mechanical type. Exfoliation is one type of mechanical weathering where rocks weather by peeling off in sheets. Rocks underneath are under high pressure from underlying rocks. Also, these rocks are experiencing progressively lower pressure from overlying rocks. This creates tension due to unbalance force. Crack formation relieved this tension which will eventually result to exfoliation.

What happens after genetically modified plasmids are inserted into bacteria?

Answers

The answer to the question is: Once a new DNA is inserted, the modified plasmid can be grown in bacteria for self-replication to make endless copies.
>The plasmid is genetically modified to produce 1 or 2 specific proteins from a pathogen and then purified for immunization.

>A plasmids are small double-stranded unit of DNA.They are usually circular but sometimes linear, that exists independent of the chromosome and is capable of self-replication. Each plasmid carries only a few genes.

Why is purity important in crime investigations?

4.Of the controlled substances, which schedule of drugs is the average person most likely to have in their homes? How are the controlled substances in this group different from those in the other schedule levels?

Answers

If I am working as a forensic scientist and I am given an unknown powder, I would analyze this and hope to find out where did this belong.

You find that the unknown powder contains the illegal drug cocaine. If someone were to ask you to determine the purity of the substance.

Is Purity important in criminal investigations-

The purity of the substance would mean what proportion of the most component of cocaine is present during this powder.

Purity is vital in criminal investigations because it'll assist you to determine what proportion of the most component is present therein substance, the most component is that the active ingredient of that substance.

The schedule of medicine that's mostly present reception is antibiotics.

Therefore, those are the answers to these questions.

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?A.) The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.

B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.

D.) The new compounds that are formed must be more complex than the food molecules that were broken down.

Answers

#1) In order for this to occur, which of the following statements must be true?

Answer: During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken. Therefore the correct answer is choice (A).
