What is chromosomes?Write in brief about the structure of a chromosome.must include all points with explanations

Answers

Answer 1

Answer:

Please find the detailed explanation below

Explanation:

A chromosome is thread-like material that carries the long strands of the genetic material (DNA), which in turn carries the gene. The chromosome is the found form of nuclear material in the nucleus.

Due to the long nature of the DNA molecule, they cannot fit into the cell. Hence, to ensure they fit, the cell wraps the DNA molecule around a set of protein called HISTONE proteins to form a NUCLEOSOME. Each nucleosome is made up of DNA coiled around a set of 8 proteins called HISTONE OCTAMER. The nucleosome structure becomes more compacted and further wound around the histone to form a CHROMATIN. This chromatin then undergoes condensation to form the visible CHROMOSOME structure.

A. This enzyme works equally well at all temperatures.

B. This enzyme works best at 10 degrees Celsius.

C. This enzyme works best at 45 degrees Celsius.


D. This enzyme works best at 60 degrees Celsius.​

Answers

The answer is C, because the rate of enzyme activity is at its highest when the temperature is 45°C. I hope this helps!

The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.

What are the factors affecting enzyme activity ?

The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes

The rate also increases with increased enzyme concentration up to the saturation point

Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.

The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by  forming a loose complex and inhibits the activity of enzymes.

Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.

water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

Sebastian wants to make ball-and-stick models of the four macromolecules. He has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen Which molecule could he make that consists of long chains of red and black colored balls? carbohydrates lipids nucleic acids proteins

Answers

Answer:

lipids

Explanation:

There are four major biological macromolecules in living systems viz: carbohydrate, proteins, lipids and nucleic acids. These macromolecules play a significant role in the optimal functioning of every living organism. Like every other polymer, these macromolecules are made up of simpler units called monomers that defines their chemical structure. In turn, the monomers consists of chains of chemical elements held together.

According to the question, Sebastian has colored balls that represents the elements contained by each of these macromolecules. The colored balls and the elements they represent are as follows: Red: hydrogen, Black: carbon, Purple: oxygen, and Green: nitrogen.

Lipids are structurally made up of fatty acids and glycerol, which are long chains of carbon and hydrogen elements with a relatively small percentage of oxygen in the structure. An example is palmitic acid, which has a structural formula: CH3(CH2)14COOH

Hence, Sebastian could make a LIPID macromolecule, which consists of long chains of red (hydrogen) and black (carbon) balls since lipids are mostly made up of carbon and hydrogen elements in their structure.

Carbohydrates are composed of more percentage of oxygen in their structure. Hence, a long chain of only red (hydrogen) and black (carbon) balls cannot make them. Proteins and nucleic acids are made up of additional nitrogen and phosphorus elements in their structure.

Answer:

B. Lipids

Explanation:

Lipids contain carbon and hydrogen.

Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?​

Answers

Answer:

"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule. "

How are the proteins inside your body affected by the presence of water and other molecules?

Answers

Answer:

Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.

Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:

Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.

If the study on the relationship between W. bancrofti and Wolbachia is correct, then combined with the results of the trials, significant numbers of microfilariae do not survive in circulation beyond what time period

Answers

Answer:

6 months

Explanation:

First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.

When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. glycolysis; dihydroxyacetone phosphate the electron transport system; coenzyme Q glycolysis; fructose-6-phosphate the citric acid cycle; pyruvate the citric acid cycle; acetyl CoA

Answers

Answer:

 glycolysis; dihydroxyacetone phosphate

When fats are used as an energy source, the glycerol portion enters the glycolysis when it has been converted to dihydroxyacetone phosphate. Thus, the correct option is A.

What is the Glycolysis?

Glycolysis may be defined as the process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.

In order to obtain energy from fats, triglycerides must be broken down into fatty acids and glycerol through hydrolysis. The fatty acids enter to Krebs cycle and are converted into acetyl CoA.

While the glycerol portion enters into glycolysis and is converted into dihydroxyacetone phosphate.

Therefore, the correct option for this question is A.

The immune response of a host against an invading bacterium is often triggered by surface components on the bacterium that are recognized as "non-self" or "foreign" by the host. These non-self components, often protein or polysaccharide in nature, are referred to as antigens. The host responds to these antigens by making antibodies that will react with invading bacteria and mark them or tag them for destruction by phagocytes.

Indicate the bacterial structures that are likely to be antigens, to which host antibodies bind, marking the invader for phagocytosis

a. fimbriae
b. ribosomes
c. cell wall
d. plasmids
e. flagella
f. capsule
g. nucleoid

Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?

Answers

Answer:

Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.

In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.

Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.

Explanation:

Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.

How is genetic information preserved during the copying of DNA? View Available Hint(s) Hint 1.opened hint How is genetic information preserved during the copying of DNA? The information is preserved because DNA codes for RNA, which codes for protein. Genetic information is preserved in the linear sequence of the building blocks A, T, G, and C. Genetic information is preserved by base pairing between A and T and between G and C across the two strands of the double helix. The information in DNA is copied into RNA, which is used as a template to copy back to DNA.
