Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a cresc

ent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?

Answer:

please give me brainlist and follow

Explanation:

Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.

ss7ja [257]

1. Answer;

-secondary structure;

Explanation;

Protein secondary structure refers to regular, repeated patterns of folding of the protein backbone. The two most common folding patterns are the alpha helix and the beta sheet. In an alpha helix, the polypeptide backbone coils around an imaginary helix axis in clockwise direction. In the beta sheet secondary structure, the polypeptide backbone is nearly fully extended. The R-groups are alternately pointed above and then below the extended backbone.

2. Answer;

- Quaternary structure

Explanation;

-Many proteins are formed from more than one polypeptide chain. The Quaternary structure describes the way in which the different subunits are packed together to form the overall structure of the protein. For example, the human hemoglobin molecule shown below is made of four subunits.

3. Answer;

-Tertiary structure

Explanation;

Tertiary structure refers to the overall folding of the entire polypeptide chain into a specific 3D shape. The tertiary structure of enzymes is often a compact, globular shape.

The tertiary structure is the structure at which polypeptide chains become functional. At this level, every protein has a specific three-dimensional shape and presents functional groups on its outer surface, allowing it to interact with other molecules, and giving it its unique function.

4. Answer;

Primary structure

Explanation;

-It is the simplest level of protein structure and is simply a sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide chains, A and B. Each chain has its own set of amino acids, assembled in a particular order. For instance, the sequence of the A chain starts with glycine at the N-terminus and ends with asparagine at the C-terminus, and is different from the sequence of the B chain.

hammer [34]

Botulism can easily be prevented by boiling food prior to consumption.

<h3>What is Botulism?</h3>

Botulism may be defined as an imperative food poisoning that is provoked by botulinum toxin delivered in food by a bacterial species clostridium botulinum.

Clostridium botulinum inhibits the release of acetylcholine in the neuromuscular junction and causes defects in sensory perception through the central nervous system.

It can only be prevented by taking the proper boiled food prior to consumption.

The complete question is as follows:

  • boiling food prior to consumption.
  • administering antibiotics to patients.
  • not eating canned food.
  • filtering food.
  • preventing fecal contamination of food.

Therefore, the correct option for this question is A, i.e. boiling food prior to consumption.
