The nucleus of a cell contains ____ which is the physical carrier of inheritance

horrorfan [7]

A cell's nucleus contains the DNA of the organism. The DNA is the same throughout the organism, but is expressed differently to create different cells (muscles, optic cells, bone, etc.)

Sorry for the delay, hope this helps :D

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.

What are the two ways that organisms on the bottom of deep sea food chains acquire energy? a. photosynthesis and chemosynthesis

aliina [53]

The correct answer is (B) chemosynthesis and marine snow are the two ways that organisms on the bottom of deep sea food chains acquire energy.

What is the meaning of chemosynthesis and marine show?

Chemosynthesis is the utilization of energy supplied by inorganic chemical processes to make food in bacteria and other organisms. To generate a sugar, all chemosynthetic organisms require energy provided by chemical processes, although various species employ different methods.

Marine snow is a shower of biological particles that falls from the upper ocean to the deep sea. Marine snow refers to biological material that descends from higher in the water column. Some flakes fall for several weeks before reaching the ocean floor.

Why are viruses considered nonliving but bacteria are considered living? Give to reasons.

Andreyy89

Viruses aren't made up of living cells, like plants and animals are, they either consist of DNA or RNA surrounded by coating of protein. Versus also like the properties of living things. They have no energy, they do not produce waste, and they do not respond to stimuli. they do not reproduce independently but must rely on invading living cells and feeding off a them.

Therefore, there are many reasons my viruses are considered non living but the biggest reason is because they cannot survive on their on and have to feed and get their nutrients off of living things

And bacteria is considered living because it can do all these things that viruses cannot do.
