List and describe three ways that bacteria can acquire new genetic material

OLga [1]

Answer:

The three most common ways that bacteria diversify their DNA are transformation, conjugation, and transduction. Genetic Material: the material in our cells that makes us who we are inside and out.

Deoxyribonucelic Acid (DNA): hereditary material found in the nucleus.

Ribonucleic Acid (RNA): genetic material that differs from DNA through its chemical bases.

DNA contains all the secrets that make you so awesome! So, it is super important that the cell keeps the DNA safe. DNA has so much information that it could stretch from the earth to the sun four times! No seriously, four times! I'm sure you're thinking, how does all that information get into something so small? Well, DNA is highly organized in order to keep all information safe, yet accessible to the cell. This is a great thing because you don't want to lose your awesomeness! DNA is comprised of four chemical bases also known as nucleotides: adenine (A), guanine (G), cytosine (C), and thymine (T). These bases pair with one another, A with T and C with G. Each base is attached to a sugar (ribose) and a phosphate molecule: hence the name deoxyribonucleic acid.

Now that we have the basic building blocks of DNA, let's get into the structure. DNA is double stranded, and each strand is held together by the pairing of the nucleotides. Remember what we mentioned above: A loves T and C loves G. These bases never cheat on one another; they only pair with the partner they love! The double stranded DNA is spirally coiled to form a helix. You will find many textbooks refer to DNA as a double helix. This double helix looks much like a ladder with the nucleotides representing the rungs on the ladder and the sugar and phosphate are the sides. The double helixes are then wrapped around proteins called histones and packaged into chromosomes.

The other type of genetic material called ribonucleic acid (RNA) is structurally similar to DNA, but there are a few differences--primarily in their chemical bases. Before we get more into the differences, let's examine the similarities. Both have a sugar, phosphate group, and four chemical bases. Unlike DNA which is double stranded, RNA is single stranded. The other major difference is the bases that are found in RNA. RNA contains adenine (A), guanine (G), cytosine (C), and uracil (U). So, in RNA the base thymine is replaced with uracil. In RNA the base pairs are A loves U and C loves G.

a krabby blind whale has married pearl who has normal vision. oneof their two sons is also colorblind. what arr the genotypes of

Alik [6]

Answer:

Heterozygous dominant (Bb) and homozygous recessive (bb)

Explanation:

This cross involves the gene that codes for color blindness in whales. The allele for no color blindness/normal vision (B) is dominant over the allele for color blindness (b). This means that B will mask the phenotypic expression of b in a heterozygous state (Bb).

According to the question, one of the parents is color blind meaning it possesses the homozygous recessive genotype (bb) while the other parent (pearl) has a normal vision which can either be homozygous dominant or heterozygous dominant since the normal vision allele (B) is dominant.

However, since one of the two offsprings (sons) is also color blind, this implies that the parent with normal vision is heterozygous i.e. contains both dominant and recessive alleles, for the trait. What happens is that, when a bb and Bb parent are crossed, they produce gametes with either a recessive or dominant allele.

The Bb produces gametes with B and b alleles while the bb produces gametes with b and b alleles. When this are crossed using a punnet square, four possible offsprings will be produced with two distinct genotypes: Bb and bb. Hence, this means that there is a 1/2 chance of producing an offspring with the recessive trait from this cross as the case is in the whales.

Which factors affect hormone levels in your blood

guajiro [1.7K]

Answer:

The endocrine system regulates how much of each hormone is released. This can depend on levels of hormones already in the blood, or on levels of other substances in the blood, like calcium. Many things affect hormone levels, such as stress, infection, and changes in the balance of fluid and minerals in blood. hope it helped
