Answer:
The tendency of water molecules to stick to other molecules also allows water to dissolve substances that are important to life, such as ions, DNA, and many proteins. This is necessary for life because molecules that have been dissolved in water or another polar solvent interact with each other more readily.

(a) deletion(b) inversion (c) duplication(d) insertion
Answer: (d) insertion
This mutation occurs when (an) additional nucleotide base pair/s attach themselves into an existing DNA strand. This can possibly result to diseases such as cystic fibrosis and myotonic dystrophy.
Answer:
Time taken by space shuttle = 714.28 m/s
Explanation:
Given:
Distance cover by space shuttle = 500,000 meter
Speed of space shuttle = 700 m/s
Find:
Time taken by space shuttle
Computation:
Time taken = Distance / Speed
Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle
Time taken by space shuttle = 500,000 / 700
Time taken by space shuttle = 714.28 m/s
Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
