Ans.
Lipids are a class of biomolecules, made up of fatty acids and fatty acid derivatives. Lipids are non-polar, water insoluble organic compounds, which include fats (triglycerides), steroids, phospholipids, and natural oils. Lipids play role in different functions, such as in membrane synthesis (phospholipids), energy storage (fats), and signalling (steroids).
Thus, the correct answer is option) 'lipids.'

the Threshold potential
Explanation:
The true statement about the mother of this family tree is that she is a carrier for color blindness.
The correct option is (B).
Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.
It is a condition in which a person is unable to distinguish between different colors.
The most common colors are greens and reds, but it can also happen with blues.
This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.
Thus, option (B) she is a carrier for color blindness is correct.

B,
since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.
Answer:
As you move from an animal's class to its order, it becomes part of a smaller group that is more closely related.
Explanation:
There are seven levels of classification for animals. The highest level of classification is Kingdom which is Animalia that include all the animals present on earth.
So the seven-level of classification are Kingdom, Phylum, Class, Order, Family, Genus, and Species. When we move down in the classification level the similarities increases between animals and when we move up from species to kingdom the similarities decrease between animals.
So by moving from higher-level like class to lower level like order the number of animal groups will become less and they become more closely related due to increase in the genetic similarities between them.
