3 0

Answer:

Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.

Explanation:

hope this helps :)

The shape of a protein molecule is influenced by
Rus_ich [418]

Answer:

The answer is C. its sequence of amino acids.

The protein's shape is influenced by its sequence of amino acids or primary structure.

Explanation:

The primary structure of a protein molecule is dependent on the amino acid chain sequence it has. The amino acid chain's <u>linear</u> structure is composed of <u>covalently bonded</u> amino acids via peptide bonds. This serves as the <u>overall backbone </u>of the protein.

<h3>Additional notes: </h3>

Secondary structure of protein

It defines the 3-dimensional shape of the<u> locally folded polypeptide</u>. They come in two forms, the alpha helices and beta sheets. During the formation of the primary structure, acidic and basic amino residues may cause kinks and turns, re-configuring the 3-D shape of the local polypeptide.

Tertiary structure of protein

This determines the overall 3-dimensional structure of the protein. The structure is due to the <u>linking of the R groups</u> of the related amino acids, <u>hydrophobic bonds</u>, and <u>disulfide bonds</u>. These bonds are <u>highly stable</u> and are not easily changed or destroyed.

Quaternary structure of protein

It is a structure that consists of multiple folded polypeptide chains or subunits. This allows the protein to have m<u>ultiple functions</u>. <u>Non-covalent forces</u> keep these structures together, making it <u>prone to rapid conformational changes.</u>

The 4th one down, then the 2nd, then the 1st.
So that would make:

Carbon from carbon dioxide is used to make G3P, a three-carbon molecule.

The molecule G3P is combined with nitrogen to make amino acids.

The plant assembles synthesized amino acids into proteins.

Answer:

Hypothesis, the amount of light must be enough to provide for the plant but not too much where it'll die and vice versa.

The amount of water should be enough that the plant can absorb it to sustain itself but too much or too little

Plant food in small quantities will help but too little or too much won't
