Skin remains red after a bad sun burn because:

inflammation causes increased blood flow.

Explanation:

When our skin is exposed to sun rays , the epidermal layer starts getting damaged. The damage to the cell caused by  sun rays triggers the  melanin secretion. Increased secretion of melanin results in darkening of the exposed region .

However, the damage and inflammation to the skin increases blood flow to the skin, this causes reddening of the skin.

The part of plants that contains structures needed to absorb sunlight and carbon dioxide is the ________?
Eduardwww [97]

Answer:

The part of plants that contains structures needed to absorb sunlight and carbon dioxide is the chlorophyll.

Explanation:

Photosynthesis is the process by which plants produce glucose.

The process of photosynthesis requires light energy which plants get from trapping the sunlight. The area of the plant which contains structures to absorb sunlight and for photosynthesis is the chlorophyll. Chlorophyll contains a green coloured substance termed chloroplast. Chloroplast is the site where photosynthesis takes place. Chloroplast is also the structure which is responsible for giving green colour to the leaves.

Resethelp 1. Structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms lo
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.
