Four haploid gametes are formed

You are asked to culture an unidentified sample of animal tissue. You notice that the cells seem to fail to exhibit density-depe

Step2247 [10]

Answer:

The correct answer is a cancerous tumor.

Explanation:

Density-dependent inhibition refers to the phenomenon in which the crowded cells stop proliferating. In the process, the group of cells present in a region force competition for space, nourishment, and growth factors. Thus, when the cells are clumped together, they receive the signals to stop dividing further. Thus, in density-dependent inhibition, when the density is high no division of cells takes place.

Density-dependent inhibition is a process in which the growth of the cells is restrained to a specific limit of density, after that the growth gets prevented, probably due to cell-cell contacts. On the other hand, the tumor cells generally do not possess density-dependent inhibition, due to this, the cancer cells show unlimited growth without getting ceased. Therefore, in the given case, the source of the tissue sample is primarily a cancerous tumor.

algol [13]

Answer: Option B.

Homeostasis.

Explanation:

Homeostasis is the ability of an individual to maintain it's internal state despite changes in the outside environment.

Homeostasis is a process to stop bleeding and keep blood in a damaged vessels. Homeostasis is the first stage of wound healing, which is a process that transform liquid blood to gel like. It is also called coagulation.

The CFTR protein is made up of 1,480 amino acids linked together in a chain. Some

weqwewe [10]

Answer:

The answer is D) It will affect the primary, secondary, and tertiary structures of the CFTR protein.

Explanation:

The deletion of phenylalanine (F) in position 508 or F508, disrupts the sequence of amino acids and polypeptides, as seen in the primary structure.

It also affects the secondary structure since it can alter the folding or kinks of the alpha-helices or beta-sheets of the local polypeptide chain.

For the tertiary structures, it will affect the overall shape of the CFTR protein, and ultimately, alter its function in the body which is to produce thin, free-flowing mucus in the respiratory, digestive, and reproductive system, etc.

<h3>What is the CFTR Protein?</h3>

Normally, the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein functions as a membrane channel protein that transports negatively-charged ions, such as chloride ions, in and out of the cell. It also transports water which is used to form thin, free-flowing mucus seen in the respiratory, digestive, and reproductive systems. It can also influence other channels to regulate the entry of sodium ions across plasma membranes seen in the pancreas and lungs.

The CFTR protein mutation found in Cystic Fibrosis (CF) is present in almost 70% of CF patients. The mutation alters the structure of the chloride ion channel and movement of chloride ions and water in and out of the cell. Thus, impairing the production of mucus, which is characteristically sticky and thick seen in Cystic Fibrosis.

15 POINTS Two puppies are born in the same litter.One has blue eyes and the other has brown eyes.Develop a hypothesis as to why

Svetlanka [38]

They have different colored eyes because their parents do. Their parents could also have mixed genetics. This means that their parents could have dominant AND recessive traits (heterozygous), leading to one of the puppies to having full recessive traits.
