1.What is meant by Plasma therapy ? Is it a remedial treatment for Coronavirus? Express your answer with valid points

Answers

Answer 1

Answer:

It is a therapy that involves the use of plasma from recovered patients (which is composed of antibodies against the virus)

Explanation:

The immune system of patients already recovered from viral diseases naturally generates defensive molecules that circulate in the blood. These molecules are known as 'antibodies', and they are localized in the plasma of the blood, which is composed of coagulation factors, albumin, fibrinogen and, of course, antibodies. These antibodies bind to specific viral antigens in order to promote their neutralization and destruction. In consequence, the plasma from recovered patients contains particular antibodies that may be used to treat specific diseases.

Which of the following descries a solution that contain a buffer? A. Sodium hydroxide, a base, is added to the solution, and the pH of the solution becomes higher. B. Citric acid is added to the solution, but the pH of the solution does not change. C. Acetic acid is added to the solution, and the pH of the solution becomes lower. D. Distilled water is added to the solution, and the pH of the solution does not change.

Answers

Answer:

B. Citric acid is added to the solution, but the pH of the solution does not change.

Explanation:

In chemistry, buffer solutions or simply called Buffer are solutions that resist a change in pH when an acid or base is added to them i.e they maintain a constant pH. This is as a result of the content of the solution. A buffer may contain a weak acid and its conjugate base (salt) or a weak base and its conjugate acid.

Hence, when a strong base or acid is added to them, they still restore the original pH of the solution due to the reaction that removes or neutralizes the hydrogen or hydroxide ions from the acid and base added to them respectively. This is what happens when Citric acid is added to the solution, but the pH of the solution does not change.

Citric acid, which is an acid, does not practically increase or decrease the pH of the solution. Hence, the solution is called a buffer.

Answer:

Citric acid is added to the solution, but the pH of the solution does not change.

What molecule is required each time the myosin head detaaches from one site and reattaches to another

Answers

Answer:

The adenosine triphosphate (ATP) molecule

Explanation:

The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

(05.05 MC) Exposing human subjects to experimental manipulations such as high levels of toxins is unethical. We often use model organisms for this reason. What attributes would you look for in selecting a good model organism for investigating the impact of toxins in humans? A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible. Cost is the only consideration in selecting a model organism, since all living things are made of cells anything found will apply to humans. The best choice will must be the very closely related to humans, such as chimps, since anything found in other species will not apply to humans. The most important consideration in selecting a model organism is how the public will feel about doing experiments on that species, so the best choice would generally be a very simple organism like bacteria that people don't care very much about.

Answers

Answer:

A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.

Explanation:

The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:

Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.

Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists

B. could destroy the hypothesis of continental drift

C. could not provide a mechanism for moving continents

D. could explain how the seafloor was being destroyed

Answers

Answer:

C. could not provide a mechanism for moving continents

Explanation:

Without the discovery of magnetic reversals recorded on the ocean floor, scientists  could not provide a mechanism for moving continents.

Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents  and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.

Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.

The study of a living being is called biology.

The correct answer is C.

Without the discovery of magnetic reversals recorded on the ocean floor, scientists could not provide a mechanism for moving continents because magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents and the degree of asymmetry varies with the same rhythm of the magnetic reversal rate.  Therefore the discovery of magnetic reversals is important to identify the mechanism for moving continents.

Hence, the correct answer is C that it could not provide a mechanism for moving continents.

A. Bb, bb
B. BB, bb
C. BB,BB
D. Bb,BB

Answers

I think its Bb, bb because if julie has blonde hair then it's most likely to be Bb, bb

If Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

What do you mean by Genotypes?

Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for specific studies in order to express some genetic characteristics.

According to the context of this question, if the trait of Blonde hair is recessive in nature. This means that both the alleles of this gene are recessive, i.e. bb.

Now, if Julie has blonde hair, which means both alleles are recessive. So, the genotypes of parents of Julie are either homozygous recessive or heterozygous in nature. This characteristic is well determined by option 1.

Therefore, if Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.
