A mother carries one allele of a recessive gene for a disease on an autosome, and the father carries no recessivealleles of the gene for that disease. What is the likelihood of their child having the disease?
0%
100%
75%
50%

Answers

Answer 1

Answer:

Answer:0

Explanation:

Answer 2

Answer: because the gene is recessive that means both parents need to carry it for any likelihood so since the father does not carry the gene that means the answer is 0%.

Student measures the mass of a paper clip. The students data table is shown below. The acceptable value for the paper clips is 1.14g.Trial # Mass
1 2.45 g
2 2.40 g
3 2.42 g

which of the following best describes the students measurements

the students measurements were accurate, but not precise

the students measurements were precise, but not accurate

the measurements are neither accurate nor precise

the measurements are both accurate and precise

Answers

Answer:

Option , B, the students measurements were precise, but not accurate

Explanation:

It is given that the acceptable value for the paper clips is 1.14 grams.

An accurate value is the one which is close enough to the accurate answer and in case when the number of readings taken with in an experiment are close to each other then they are said to be precise.

Here the value obtained through three reading are close to each other hence, they are precise but none of these values is close to the acceptable value for the paper clips.

Hence, option B is correct.

I believe the correct response is that the student measurements were precise but not accurate.

Which of the following monomers would be used to make the double helix of a DNA molecule?

Answers

The monomers that would be used to make the double helix of a DNA molecule are the phosphorus+ sugar+ base. The correct option is A.

What is DNA?

DNA is a genetic material that is present in the nucleus of the cell. It is present in all plants and animals. This is the important material in the body that makes every individual unique.

DNA is made up of three substances. They are phosphorus sugar, which makes the backbone of the helix. The bases are present in between the helices, they are joined by hydrogen bonds.

There are two hydrogen bonds present between adenine and thymine. There are three hydrogen bonds present between guanine and cytosine. The bases keep the two helices together.

Thus, the correct option is A, phosphorus+ sugar+ base.

a female impala has one or two calves and then spends months feeding and protecting them. a female salmon lays thousands of eggs and then returns to the ocean. what are some advantages from each type of life cycle?

Answers

If said animal has given birth and nurses the calve that species has the advantage of the mother being able to protect and care for the calves.The down side is that you can only have a few amount of children.While if you are the salmon and laid thousands of eggs you would have that advantage of a lot of offspring so if one of them dies the others will still live to continue on the species or survie the next day.The con is that without either of the parents protecting the children it increases the risk of them dying.

Compare mitosis and meiosis: please list 3 things that are unique to mitosis, 3 things thatare unique to meiosis, and 1 thing that they have in common. *

Answers

Mitosis occurs in the somatic cell, it is an equational division, mitosis is required for the repair and growth of the cell and organism consequently.

While meiosis occurs in gametes or germ cell, it is a reductional division, meiosis is responsible for the formation of sex cells as sperm and eggs in the organism.

Both mitosis and meiosis are responsible for splitting the nucleus and DNA and these are passed on to the two daughter cells formed.

Explanation:

Mitosis is the process of cell division in which the cell divides and each cell is identical to the parent cell in the context of DNA and its nature There are four phases of DNA as Prophase, metaphase, anaphase and telophase. The daughter cells formed, have diploid (2n) number of chromosomes.

While meiosis is the process of cell division in germ cells which start with one cell and ends in 4 haploid cells. Meiosis is completed in two steps as meiosis 1 and meiosis 2.
