Answer:

Helium is considered as noble gas or inert gas because it belongs to noble family in the periodic table.

Explanation:

What do the amino acids tyr, asn, and thr have in common?

grandymaker [24]

Answer:

The given three amino acids are polar in nature.

Explanation:

The structure of amino acid is generally composed of four parts:

1. Carboxylic group

2. Amino group

3. Hydrogen atom

5. Alkyl or Aryl group

The central carbon atom also known as alpha carbon which is surrounded by amino group on one side, H atom on top, Amino group on right side and Alkyl or Aryl group on down side.

The R group given amino acids are as,

Tyr = -CH₂-Ph-OH

Asn = -CH₂-COO-NH₂

Thr = -CH(OH)-CH₃

Hence, due to presence of Hydroxyl groups and Amine groups on Alkyl or Ary l chain the given three amino acids get polar in nature.

Some bacteria live in the roots of plants like soybeans and peas. What is the role of these bacteria in the nitrogen cycle.

love history [14]

Answer:The nitrogen present in the soil is not directly used by the bacteria. It can be used only when the nitrogen is converted into usable form. These bacteria convert atmospheric nitrogen into ammonia, then nitrite which is then converted into nitrate. This nitrate is used by the roots of the plants like soybeans and peas. This is the role of bacteria present in the roots of the plant to convert atmospheric nitrogen into usable form that can be used by plants.
