I think the answer is sexual reproduction to carry out selective breeding.
Answer:
Sex-linked trait
Explanation:
When a gene is present on the X chromosome, but not on the Y chromosome, it is said to be X-linked. X-linked genes have different inheritance patterns than genes on non-sex chromosomes (autosomes). That's because these genes are present in different copy numbers in males and females.

*-*-*-*-**-*-*-*-*-*-*
When the sun gets hot, water from any lakes, oceans, rivers, or any part with a large body of water evaporates.
This means that water turns into a gas form called "water vapor" that rises into the atmosphere.

Answer:
shells 1, 2 and 3 are full and shell 4 has one electron
Explanation:
The distribution fo the electrons possessed by an atom in the shells surrounding it is termed as its electronic configuration.
According to the rules of writing the electronic configuration:
1. The first shell can be occupied by a maximum of two electrons.
2. the subsequent shells can be occupied by a maximum of 8 electrons.
3. the subsequent shells are filled only once the lower shells have been filled.
Based on these rules, the electronic configuration of potassium should be 2, 8, 8, 1. (2+8+8+1 = 19).
Thus, we can see that the first three shells are filled, and the last one has one electron left.
