QveST [7]

I think that they will gain water in the distilled water and lose water in salty water. I think water will be lost because salt is used as an drying agent, it is why when it snow they will put salt on ice to keep the ice from being slippery because it dries things up.

Of the answers below, what is the smallest nucleotide sequence that could code for a protein with 300 amino acids?

ololo11 [35]

The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.

Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.

When a plant grows toward or away from a stimulus, it’s called a tropism.

harina [27]

Explanation:

Phototropism- a response to light stimulus that directs the stem to grow toward the light and roots to grow away from it.

ii. Gravitropism- Stems and leaves grow away from the force of gravity while roots grow toward it.

iii.Thigmotropism - growth in response to touch stimulus. The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.
