What is an ephemeral stream? A)one that flows only after rainfall B) one that flows only in flat lands C) one that is formed onl
kupik [55]

Answer: Option (a) is the correct answer.

Explanation:

The stream that flows during or after the rainfall is called an ephemeral stream. This stream occurs in areas where there is less rainfall or deficiency of moisture.

The stream that flows only in flat lands is called as river.

Mechanical weathering results in the breaking of rocks causes ice wedging.

Chemical weathering results in the change in molecular structure of rocks and soil.

Thus, it can be concluded that option (a) is the correct answer.

Researchers tested a meteorite for organic molecules containing 13C and 15N, which are carbon and nitrogen atoms with one extra
Hoochie [10]

Answer:

The correct option is  2.No, because only electrons are involved in bonding.

Explanation:

The type of bond formed by carbon and nitrogen (carbon-nitrogen bond) is covalent bond

Also known as molecular bond, a covalent bond involves the sharing of pairs of electrons (known as bonding pairs or shared pairs) between the carbon and nitrogen atoms forming stable, balanced forces in attraction and repulsion as they share common electrons in their compounds.

This electron sharing covalent bond is what enables the formation of the several compounds between carbon and nitrogen for example, in an amine, nitrogen which has five electrons, has two remaining electrons that forms a lone pair whereby it can combine further with other elements.

Hence the factor that influences the bonds to make the numerous organic molecules is the available electrons which constitutes the shared electron pairs in covalent bonds while the neutrons which function is to keep the repulsive forces of positively charged protons from ripping the nucleus apart.
