Critical thinking : Do magnets need to touch a piece of iron or another magnet to exert a magnetic force on the iron or other magnet?

Answers

Answer 1

Answer:

I wouldn't think so because it is the magnetic field that Attracts and repels. When iron is magnetised to something don't the molecules lineup in the North the South pattern or something like that to create a magnetic field and stick together.

I might be wrong because this is my personal opinion on the matter.

Answer 2

Answer:

no because the magnetic force attracts the magnet or the iron to it

In a strand of DNA, if the percentage of thymine is 30%, what would the percentage of cytosine in the same DNA strand be?

Answers

Answer: 20%

Explanation:

I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.

1. Identify one environmental factor that could cause a base sequence in DNA to be changed to a different base sequence.

2. Explain why, in a mammal, a mutation in a gamete may contribute to change in the population of the organism while a mutation a body cell will not.

Answers

Answer:

Explanation:

1     Long term exposure to harmful genotoxic chemicals or ionizing radiation can cause changes in the base sequence of DNA.Chemicals might induce DNA mutations, such as polycyclic hydrocarbons (fumes found in oil stations, or smoke from a tobacco cigarette), intercalating agents such as Ethidium Bromide (carcinogen), but also radiations such as UV-radiation (C and T bases are most vulnerable and would bind to identical bases unstead of their

2    Genetic changes that are described as de novo (new) mutations can be either hereditary or somatic. In some cases, the mutation occurs in a person’s egg or sperm cell but is not present in any of the person’s other cells. In other cases, the mutation occurs in the fertilized egg shortly after the egg and sperm cells unite. (It is often impossible to tell exactly when a de novo mutation happened.) As the fertilized egg divides, each resulting cell in the growing embryo will have the mutation. De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder.

Somatic mutations that happen in a single cell early in embryonic development can lead to a situation called mosaicism. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells. As all the cells divide during growth and development, cells that arise from the cell with the altered gene will have the mutation, while other cells will not. Depending on the mutation and how many cells are affected, mosaicism may or may not cause health problems.

Certain hormones , such as follicle stimulating hormone (FSH) and luteinsing hormone (LH) affect the reproductive organs of both males and females . Other hormones, known as _______, have significantly higher concentrations in one gender rather than the other. ______ and ______ are the most critical of these, playing a key role in the development of reproductive systems and gender-specific traits. High concentrations of these hormones in the opposite gender offten result in significant complications. _______ stimulates cells to produce testosterone in males, while in females, this hormone signals an increase in ovulation hormones to prepare for pregnancy. ______ stimulates the production of sperm in males, but signals growth of the ovum in females.

Amino acids

Explanation:

Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein. Figure 2: The amino acids specified by each mRNA codon.

Describe your diagnosis for the patient. How did the chlorine gas affect concentration difference, diffusion distance, and surface area in the patient’s lungs? Explain how these affected the diffusion rate.

Answers

The concentration difference and surface area lead to decrease but the diffusion distance increases due to application of chlorine.

The difference in the concentration of a substance between two regions is known as the concentration gradient.

Surface area is the total area that the surface of the object occupies.

Diffusion rate is defined as the change in the quantity of diffusing molecules inside the cell in a specific period of time.

The chlorine gas greatly affected the concentration difference because it lowers the value. The gas increases the diffusion distance but decreases the surface area of the patient's lungs. The decrease in the concentration difference leads to slower the diffusion rate.

It is because there is less difference in the concentration of both regions i.e. lungs and the surrounding atmosphere and when there is equal amount on both sides the diffusion of gas molecules stopped so we can say that decrease occur in the concentration difference and surface area but increase occur in the diffusion distance
