Following the Hardy-Weinberg equilibrium theory, in a population of six million people, 1,080,000 individuals are healthy and carriers (heterozygous) for the trait.

The Hardy-Weinberg equilibrium is a theory that states that populations in equilibrium get the same allelic and genotypic frequencies generation after generation.

These populations do not evolve. No evolutive forces are acting on them.

Assuming a diallelic gene, frequencies are

Allelic frequencies

Genotypic frequencies

In a population in equilibrium,

We will consider these equations to solve the problem.

Because we have the frequency of the homozygous recessive genotype, we can get the allelic frequency.

Now, by clearing the equation p + q = 1, we can get the dominant allele frequency. And then, the frequency of the homozygous dominant genotype.

Finally, we can get the frequency of the heterozygous genotype

Wildebeests live in great numbers on East Africa's vast plains, where dramatic wet and dry seasons cause a bounty of grass at sometimes, and a dearth of good grazing at others. To survive, the wildebeest must migrate to find food.

The wildebeest migrate around the Serengeti, and into the Masai Mara for the sole purpose of following the rainfall. For their calving from December - March they always begin their cycle in the Southern Serengeti area of Ndutu and follow wherever the grass is green. Wildebeest migrate on a loop path through Tanzania and Kenya following the seasonal rains even when that involves passing through dangerous territory. This is a modal window. Wildebeest, also called gnus, are members of the antelope family.

The given statement, "Most digestion and absorption of food occurs in the" is incomplete and doesn't provide any clue about the required answer. Therefore, it is essential to know the full statement to provide a valid answer to this question.

The process of breaking down food into smaller components (nutrients) in our digestive system so that the body can absorb them for energy production and other metabolic processes is called digestion. The digestive process can be divided into two types: mechanical digestion and chemical digestion.

Mechanical digestion involves the physical breakdown of food into smaller particles through chewing and grinding. On the other hand, chemical digestion refers to the breakdown of food into smaller nutrients with the help of digestive enzymes and other secretions from the gastrointestinal tract.

After the breakdown of food, the process of absorption takes place. Absorption is the process in which the nutrients, minerals, and other components of food are absorbed by the small intestine and transported to other parts of the body. The small intestine is a critical part of the digestive system responsible for nutrient absorption, while the large intestine absorbs water and minerals.

Nutrients from food are absorbed by the small intestine into the bloodstream and then transported to cells throughout the body for energy production, tissue repair, and other metabolic processes.

In conclusion, the process of digestion and absorption of food is crucial for the proper functioning of the body. The majority of digestion and absorption of food occurs in the small intestine.

The study of biogeography examines how living entities are distributed geographically and how abiotic causes may have an impact on that distribution.

Latitude and elevation play a major role in the variation of abiotic elements like temperature and rainfall.

The make-up of plant and animal communities changes as these abiotic elements do. For instance, you would see progressive changes in plant communities if you started your tour in the equator and walked north.

You would observe broad-leaved evergreen trees in tropical wet forests at the start of your journey, which are typical of plant communities found close to the equator.  These broad-leaved evergreens would eventually give place to seasonally dry woodlands with scattered trees as you traveled north.

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

A mutualism occurs when two species have a long-term relationship that benefits both of them (+/+ interaction). Some fungi, for example, create mutualistic relationships with plant roots. The plant may photosynthesize and gives fixed carbon to the fungus in the form of sugars and other organic compounds.

The presence of several species in an ecosystem balances it. The species in an ecosystem interact with one another in some way. For example, the existence of a plant species will offer food for the numerous herbivores found in an ecosystem. A predator may consume a variety of prey. As a result, the existence of diverse prey reduces the likelihood of a species becoming extinct in the ecosystem. As a result, all creatures in an ecosystem are dependent on one another in some way.

Answer:

Explanation:

The new Velocity_max is 0.5 mM per minute, which corresponds to option A.

To calculate the new Vmax, we can use the Michaelis-Menten equation, which relates the reaction rate (Vo) to the substrate concentration ([S]) and the maximum reaction rate (Vmax). The equation is given as:

Vo = (Vmax × [S]) / (Km + [S])

We have two sets of data points:

[S] = 5.0 mM, Vo = 0.25 mM/min

[S] = 2.0 mM, Vo = 0.333333333333 mM/min (approximately 1/3 mM/min)

From the first set of data, we can calculate the Km value by rearranging the Michaelis-Menten equation as:

Km = ([S] × Vmax) / (Vo - Vmax)

Substituting the values, we get:

Km = (5.0 mM × Vmax) / (0.25 mM/min - Vmax)

Similarly, from the second set of data, we get:

Km = (2.0 mM × Vmax) / (0.333333333333 mM/min - Vmax)

Since Km should be constant, we can set the two equations equal to each other:

(5.0 mM × Vmax) / (0.25 mM/min - Vmax) = (2.0 mM × Vmax) / (0.333333333333 mM/min - Vmax)

By solving this equation, we find Vmax = 0.5 mM/min.

Therefore, the new Vmax is 0.5 mM per minute, which corresponds to option A.

Mitosis is the division of a parent cell into two daughter cells which contain the genetic material which is exactly similar to parents. The daughter cells are often called as clones.

Mitosis is also known as Equational division. Mitosis is the process of cell division, in which the nucleus undergoes division in eukaryotic cells that occurs when a parent cell undergoes division to produce two identical daughter cells.

During the process of cell division, the karyokinesis is followed by the cytokinesis. Karyokinesis is the division of nucleus and it is divided into four phases: Prophase, Metaphase, Anaphase, and Telophase. In the prophase of mitosis, the spindle fibers starts attaching to the chromatids of chromosomes and the chromatids becomes distinct which are then arranged on the equatorial plane and later divides into two daughter cells.
