1.Identify the role of endocrine glands in growth/development, and in regulation of metabolism.
2. Compare hormonal and nervous control of homeostasis

3. Classify the mechanisms through which hormones affect target cells, the major chemical classifications of hormones, and the principles of positive and negative feedback

Answers

In this question we are going to answer a series of questions about the human endocrine system, hormone release and homeostasis.

What is human endocrine system, hormone release and homeostasis?

1. Endocrine glands produce hormones and release them directly into the bloodstream.

Hormones are the products of secretion from the endocrine glands. They control various activities in the human body, hence the importance of these glands.

2. It is through the feedback mechanism that, for example, the regulation of hormone secretion and the control of temperature and blood pressure occur.

Thanks to this control, it is possible to guarantee the harmony of the systems and, consequently, the homeostasis (balance of the internal environment).

3. Hormones can be divided into four groups, based on their chemical structure,form of synthesis and storage, solubility, half-life, form of transport, receptors on cell and mechanism of action:

PeptidesSteroidsAmines and Eicosanoids.

Both positive and negative feedback are extremely important for our body to function properly. However, these two mechanisms have differences. In negative feedback, the body produces a response that reduces the initial stimulus, while in positive feedback, the response reinforces the stimulus.

RNA Polymerase utilizes a strand of DNA to create a new complementary strand of RNA.
True or False?

Answers

True hopefully this helps

RNA Polymerase utilizes a strand of DNA to create a new complementary strand of RNA. This statement is True.

What is Transcription?

Transcription is defined as the process of copying a segment of DNA into RNA. These segments of DNA are transcribed into RNA molecules that can encode proteins which is called as messenger RNAs are produced. Other segments of DNA are copied into RNA molecules called non-coding RNA while mRNA comprises only 1–3% of the total RNA sample.

The main steps of transcription are as follows:

1. Initiation

2. Promoter clearance

3. Elongation

4. Termination

RNA polymerase is the type of enzyme used in transcription which is a multi-unit enzyme responsible for creating a complimentary strand of nucleic acid called RNA from a single stranded DNA template through the incorporation of adenosine, cytosine, guanine and uracil nucleotides.

Thus, RNA Polymerase utilizes a strand of DNA to create a new complementary strand of RNA. This statement is True.

A table showing the observations in an experiment investigating how plants respond to gravity. The top row shows observations from a plant grown upright in a pot. The observations are as follows: the stem grew straight upward on day one, straight upward on day two, straight upward on day three, straight upward on day four, and straight upward on day five. The bottom row shows observations from the plant grown in a pot on its side. The observations are as follows: the stem grew straight outward on day one, it started to bend on day two, more bent on day three, bent like the letter L on day four, and continued to grow in a bent fashion on day five. Gravity does not affect the growth of a plant. Gravity has no effect on the plant grown on its side. The stem of a plant will grow downward with gravity. The stem of a plant will grow upward against gravity.

Answers

Answer:

X-linked recessive inheritance

Explanation:

Since the disease is primarily present in males vs females, it is a s.ex linked disease.

In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.

Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. A parakeet that is heterozygous for blue feathers (dominant) is crossed with a parakeet that is homozygous for white feathers (recessive).

A parakeet with white feathers. A parakeet with blue feathers.

According to the Punnett square for this cross, what percentage of offspring is predicted to have blue feathers?
25 percent
50 percent
75 percent
100 percent

Answers

Answer: 50% of the offspring are predicted to have blue feathers.

Explanation:

Simple Dominance

I'm going to assume since the problem didn't say otherwise that we're working with simple dominance. This is usually the first kind of inheritance that we learn about in school.

For every gene, there are two alleles, a dominant allele (B), and a recessive allele (b). We represent these as a capital letter and a lower case letter. For this problem, let's use a 'B' for blue. There are three combinations that these can come in:

BB - homozygous dominantBb - heterozygousbb - homozygous recessive

If the alleles are the same, we say the organism is homozygous for the gene. If it has one of each, then the organism is heterozygous.

In simple dominance, if there's a dominant allele present (B), the organism will always show the dominant phenotype (in this case, blue feathers). So, the only offspring that can have white feathers are the ones with a bb genotype.

Punnett Square

A punnet square is a tool used by biologists to determine the probability of two organisms' offspring having certain genotypes. For this simple cross, where we have one gene with two alleles, we just need a 2x2 square. On either side of the square, we're going to put the two alleles of each parent. Then, we'll take each allele on top and add it to the boxes beneath it. Finally, take the alleles on the side and place them in the boxes to their right. I'll attach the completed square to my answer.

Interpreting the Results

Once the entire square is filled in, we'll see the following results:

Bb x2bb x2

2/4 offspring will have a heterozygous genotype (Bb) and therefore have blue feathers.

2/4 offspring will have a homozygous recessive genotype (bb) and have white feathers.

So, one-half, or 50%, of the parakeets' offspring will have blue feathers.

If we dig deep enough we can dig them up and see what the skeletons of older organisms were like. A similar thing happens with footprints and organisms trapped in Amber.

Scientists said the lab experiments would help them understand what might already be happening naturally. . . .But other people thought such research was a terrible idea. What if these viruses escaped the lab by mistake? What if a government or terrorist organization wanted to use the viruses against their enemies?In 2013, two research groups outside the United States went ahead and conducted their own experiments. One group, led by Ron Fouchier of Erasmus University in the Netherlands, showed that the highly lethal mixed up flu virus could infect and kill ferrets. A few months later, a Chinese group led by Chen Hualan at Chinas Harbin Veterinary Research Institute showed the recombined virus could infect and kill guinea pigs. Both groups ran their studies before a worldwide ban on this type of research was put into place in 2012.One of the main ideas presented in this passage is the controversy over whether or not flu research is safe. What do these paragraphs suggest about the safety of such research? A. A worldwide ban on dangerous flu research was put into place in 2012, so the threat of people using flu viruses to attack others no longer exists.B. Since all of the information that could be learned from such research has already been discovered, scientists no longer need to create new flu viruses, and therefore the controversy is over.C. Although none of the deadly flu viruses made for research have been used by dangerous people, since that possibility still exists, the ban on the research might be important.D.
