The velocity of a helicase that moves one base in each cycle and hydrolyzes 50 ATP per second is 416.7 μm/s.

To solve this problem, we need to use the equation:

velocity = (number of ATP hydrolyzed per second) x (energy released per ATP) / (force required to move one base pair)

The force required to move one base pair is typically around 6 pN (piconewtons). The energy released per ATP hydrolysis is around 50 kJ/mol. Using these values, we can calculate the velocity:

velocity = (50 ATP/s) x (50 kJ/mol) / (6 pN x 1 base) = 416.7 μm/s

However, we are looking for the velocity of the helicase when it moves one base in each cycle. We can assume that each cycle of helicase activity involves the hydrolysis of one ATP molecule. Therefore, we need to divide the above velocity by the number of bases moved per ATP hydrolysis:

velocity = 416.7 μm/s / 1 base = 416.7 μm/s

Therefore, the correct answer is not one of the options given. The actual velocity of the helicase would be 416.7 μm/s, which is much faster than any of the options provided.

Answer:

Enzymes speedup the chemical reaction.

Explanation:

Enzymes are the molecules which are responsible for speedup of the chemical reaction. In this picture, we can see substrate attached to the active site of the enzyme. This enzyme speedup the chemical reaction and products are formed after completion of chemical reaction. When the chemical reaction is over, the products detached from the enzyme and no decrease occurs in the size of enzyme.

On the surface of cells, viruses, fungi, and bacteria are molecules (often proteins) known as antigens. Antigens can also include non-living things including , chemicals, medications, and foreign objects.

For the purpose of binding to a particular protein, B cells have B cell receptors (BCRs) on their surface. The B cells then release antibodies that adhere to the antigen and stop it from doing any harm to the body after they have bound to this protein, which is known as an antigen.

Any chemical that triggers your immune system to make antibodies against it is referred to as an antigen. Your immune system is attempting to combat the chemical because it is not recognized by it, according to this.

Answer:

Decomposition

Explanation:

Took the test

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.

Rocks are made up of minerals, which are naturally occurring, inorganic solids that have a definite chemical composition and a crystalline structure. The properties of a mineral are determined by its chemical composition and its crystal structure.

When minerals are mixed together to form a rock, the properties of the individual minerals may change because the minerals interact with each other and form new bonds. The new bonds may change the properties of the individual minerals, such as their hardness, density, and electrical conductivity.

A hypothesis is a conjecture the researcher makes to predict what is going on or what is expected to occur. It is a relationship between two variables. It is not a fact, and it needs corroboration.

--------------------------

First, let us review what the hypothesis is.

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

It explains the relation between the involved variables.

A hypothesis must

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.

Now, since I do not have the options, I am going to state two hypotheses for you to understand the concept. Then you will have to choose among your options, which do you think is the best hypothesis.

Option 1:

The grass in the yard is dying because of the high solar radiation.

Variables in this hypothesis are the grass dying and solar radiation.

The grass death/survivorship depends on the radiation. So here is the relationship between variables, the higher the radiation is, the more affected the grass is.

Since it is summer, we are assuming that high radiation is affecting the grass. So this is our conjecture. Hence, as we are not sure about it, we need to prove it.

Option 2:

The grass in the yard is dying because insects are feeding on the roots.

By previous knowledge, we know that there is a certain species of insects that increases its reproductive rate during summer, and they feed on the roots. This is a very common species, and we always see it in the grass.

So we can make this conjecture. We are not sure, but we think this might be the reason for the grass dying.

The variables are the grass dying and the insects feeding on the roots. The relationship between variables is that Because the insects feed on the roots, the grass is dying.

Note that in both cases, the hypotheses are in the present time, and the relationship between variables is very clear and explicit.

By utilizing communication strategies like Vocalizations, Visual displays and Pheromones, animals can enhance their chances of successful reproduction by attracting suitable mates and ensuring reproductive success.

Animals communicate with other members of their species for reproductive purposes through the following means:

Vocalizations and Calls: Many animals produce specific vocalizations or calls to attract potential mates. These vocalizations can serve as signals to indicate the presence of an individual ready to mate, advertise their fitness or quality as a mate, or establish territory to attract potential partners.

Visual Displays: Visual displays, such as elaborate courtship dances, colorful plumage, or displays of physical strength, are often used by animals to attract mates. These displays can be specific to a particular species or gender and serve as signals of reproductive fitness and attractiveness.

Chemical Signals and Pheromones: Animals may use chemical signals, including pheromones, to communicate their reproductive availability and attract potential mates. Pheromones are chemical substances released by an individual to elicit specific behavioral responses from others of the same species, particularly in relation to mating behaviors.

In Griffith's experiment, the result that demonstrates transformation is when the mouse dies after being injected with a mixture of heat-killed S and living R cells. The correct option is D.

The result from Griffith's experiment that is an example of transformation is option D - Mouse dies after being injected with a mixture of heat-killed S and living R cells. This is because Griffith observed that when heat-killed S-strain pneumococcal bacteria were mixed with live R-strain bacteria, the mouse injected with the mixture died. This indicated that the heat-killed S strain had transferred some genetic material to the R strain bacteria, transforming them into virulent S strain bacteria.

This transformation was the first direct evidence of bacterial genetic material being transferred from one strain to another, leading to the discovery of genetic transformation. In the blood samples from the mouse in D, living S cells were found, indicating that the genetic material from the heat-killed S strain had been taken up by the R-strain bacteria and transformed into S-strain bacteria. This result provided a basis for the study of genetic transformation and played a significant role in the discovery of DNA as the genetic material.
