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
<span>It can be aerobic respiration in the presence of oxygen or anaerobic respiration. Prokaryotic cells carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on eukaryotic cells where the mitochondria are the site of most of the reactions.</span>

Climate change is the greatest global threat to coral reef ecosystems. Scientific evidence now clearly indicates that the Earth's atmosphere and ocean are warming, and that these changes are primarily due to greenhouse gases derived from human activities.
</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent. Additionally, carbon dioxide absorbed into the ocean from the atmosphere has already begun to reduce calcification rates in reef-building and reef-associated organisms by altering seawater chemistry through decreases in pH. This process is called ocean acidification.

Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns. When combined, all of these impacts dramatically alter ecosystem function, as well as the goods and services coral reef ecosystems provide to people around the globe.

Answer:
3 yellow : 1 green
Explanation:
Yellow seed allele (Y) is dominant over the green seed allele (y).
A cross between two true breeding parents is done: YY x yy
The F1 offspring would be heterozygous Yy.
<u>If the F1 is selfed (Yy x Yy) the expected ratios for the F2 generation according to Mendel's law of segregation would be:</u>
- 1/4 YY (yellow)
- 2/4 Yy (yellow)
- 1/4 yy (green)
So 3/4 seeds of the F2 would be yellow because they have a dominant Y allele, and 1/4 would be green.
The phenotypic ratio will be 3 yellow : 1 green
