Answer:
Option D, The chance that you share an allele with either a parent or a sibling is one half.
Explanation:
All individuals receive 50 percent of their genes from each parent, Thus, it can be said that each sibling will share nearly half of their genetic material with each parent. In case of full siblings (when both the parents are same), 50 percent of their genetic material matches.
For instance,
There are two parents each with genotype AA and aa
Cross between AA and aa will produce following offspring
AA * aa
Aa, Aa, Aa, Aa
Thus, each offspring will have one gene from each parent and hence they share 50% of their genetic material with their parents
Two siblings get the same gene from their two parents. Hence, 50 percent of their genetic material matches.
Hence, option D is correct
The answer is b - high diversity and food.
Having a high starting diversity is an absolute prerequisite for a certain area to even start having a lot of different organisms living in the same spot. The other prerequisite is having a lot of food. This enables the nourishment of big numbers of different species which enable high biodiversity.
A becuz that is the only answer where it is solid
Triglycerides are Energy-storage molecules. They are formed by connecting three fatty acids to Glycerol.
Answer:
<u>Red blood cell in humans -</u> it has no nucleus. Hence it offers the cell to carry more haemoglobin.
- they are disc shaped allowing them to pass through narrow capillaries.
<u>Root hair cells in plants-</u> they have a large cytoplasm which enables them to take water from the soil.
<u>White Blood Cells in humans -</u> they have lobed nucleus and so can change their shape to pass through narrow capillaries.
