Answer:

The correct answer is option b. "The genes share a specific combination of control elements".

Explanation:

Human eye color is an example of a trait that is controlled under the influence of multiple genes (polygenic). Human eye color is mainly determined by the amount of melanin that is present in the front part of the iris, which it is controlled by up to 16 genes. Among the different genes, the ones that mainly influence eye color are: OCA2 and HERC2. These two genes share a specific combination of control elements, for instance, a regulatory element of HERC2 gene inhibits OCA2 expression as well.

How would a muscle injury surrounding a broken vessel effect hemostasis?
8_murik_8 [283]
Hemostasis is the process by which bleeding is stopped, that is, a process by which the blood is kept back in the broken blood vessel. It is the first stage in the wound healing process. 
During hemostasis, three rapid steps occur simultaneously. In the first step, the blood vessel constrict in order to reduce the quantity of blood that is flowing out, secondly, platelets stick together in order to form a temporary seal which covers the break and thirdly blood clottings formed by adding fibrin threads which serves as molecular glue on the surface of the wound.

Some organelles, such as the endoplasmic reticulum and Golgi bodies, have a large and folded structure. What is an advantage of
bekas [8.4K]

Answer:

Explanation:

In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.

mitochondria has two membrane,

It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.

The folds also enables a large surface area that makes chemical process to occur in an efficient way.

SashulF [63]

Answer:

Organelles

Explanation:

Living cells of organisms contain structures within them that perform specific functions for the cell. These structures are called ORGANELLES. Organelles are organ-like structures that are specific about their function in a cell.

Both the cells of prokaryotes and eukaryotes possess organelles, however, the organelles in eukaryotes are bounded by a membrane e.g mitochondrion, chloroplast etc. while those of prokaryotic cells are not bounded by a membrane.

The organelles inside a cell can be seen with the aid of an electron microscope. Examples of organelles are chloroplast (functions in photosynthesis), mitochondria (functions in production and storage of cellular energy), ribosome (functions in protein synthesis) etc.

kow [346]

Silt, clay, and Sand would be more likely to find the sediment near location A, while cobble and boulder would be more likely to find the sediment near location B in the diagram of the stream.

<h3>What are Sediments?</h3>

Sediments may be defined as naturally occurring elements or materials that are broken down into small pieces of fragments due to weathering and erosion.

The sediments of silt are found in soil along with other types of sediments such as clay, gravel, and sand. While cobble and boulders are those sediments that are found in the mountainous part of the geographical locations.

Thus, it is well described above.
