The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen

Naddik [55]

Answer:

The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of temporal isolation.

Explanation:

Temporal isolation is a form of reproductive isolation in which two or more species reproduce at two separate times.

For example: Northern america leapord frog mates in April and North America Bullfrog mates in july.

As in the given scenario, reproductive isolation is occuring in which two species (Monterey pine and Bishop's pine) are reproducing (producing pollens) at two separate times(February and April). Hence it is an example of temporal isolation.

Describe how the folded structure of a peptide chain and the stereochemistry of an l-amino acid illustrate the difference betwee

snow_tiger [21]

The configuration is a concept that is related to the order (poition) by which different substituents linked to the same central atom, in the case of amino acids, around the central carbon atom. So, amino acids can be divided in two groups, L- and D- forms, analogous to left-handed and right-handed configurations.

On the other hand, protein folding (folded structure of peptides) is the physical process by which a protein chain acquires its conformation (3D structure) that is usually biologically functional.

Suppose an alkane had 8 carbon atoms. How many hydrogen atoms would it have? a. 18 atoms c. 10 atoms b. 16 atoms d. 12 atoms

Delvig [45]

<h3>Answer;</h3>

A. 18 hydrogen atoms 

<h3>Explanation;</h3>

Alkanes are group of hydrocarbon that are saturated. They are saturated in the sense that each carbon atom has maximum number of hydrogen atoms.
The homologous series of alkanes has a general formula of CₓH₂ₓ₊₂.
Therefore, an alkane with 8 carbons will have; (2×8) +2 = 18 hydrogen atoms. Thus, the formula of the hyrocarbon will be; C₈H₁₈.
