The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS

Answers

Answer:

C. BbSs

Explanation:

The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.

This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.

So, the genotype must be C, BbSs

The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.

The parent's genotype will then be BbSs.

The genotype of both parents have to be heterozygous as a result of the

presence of its forms in the B and S traits. There is the presence of the

dominant (B,S) and recessive traits (bs).

The genotypes of the parent will however have both traits in them which

translates to the option C) BbSs being the most appropriate.

Answers

Answer:

According to the image that represents a cell in the human body, the true statement is that structure 4 is the cell membrane that provides exchange of O₂ & CO₂.

Explanation:

In cells, the cell membrane acts as a semi-permeable barrier to the passage of substances, including nutrients and oxygen (O₂).

One of the functions of the cell membrane is to allow the exchange of O₂ —necessary for the cell— and carbon dioxide (CO₂), a product of cell metabolism that must be removed.

In the image, the structure identified with the number 4 corresponds to a cell membrane of human cells that provides this gas exchange.

The other options are not correct because:

Structure 1 is a ribosome, not a chloroplast. Structure 2 is the nucleus, not a vacuole containing DNA. Structure 3 is a mitochondria, but protein synthesis does not occur there.

Which statement is true about mutations?
W
A. Mutations are always beneficial.
В.
Mutations are always harmful in plants.
C.
Mutations only affect humans.
D.
Mutations can be caused by high-energy radiation.

Answers

Answer:D.

Mutations can be caused by high-energy radiation.

Explanation:

"Mutations can be caused by high-energy radiation". This statement is true. Therefore option D is correct.

Mutations are changes in the DNA sequence of an organism's genome. They can occur naturally as a result of errors during DNA replication or recombination, or they can be induced by various factors including radiation, chemicals, or environmental factors.

High-energy radiation, such as X-rays or ultraviolet (UV) radiation, has the potential to cause mutations in the DNA. This radiation carries sufficient energy to disrupt the normal structure and functioning of DNA molecules, leading to changes in the genetic code.

Exposure to high-energy radiation can result in different types of mutations, including point mutations (changes in a single nucleotide base), deletions, insertions, or rearrangements of DNA segments.

It is important to note that not all mutations are harmful or beneficial. Some mutations may have no significant effect, while others can be detrimental or even provide advantages in certain circumstances, such as adaptations to new environments or resistance to specific diseases.
