The answer is: B - Mitochondria
Explanation:
The mitochondria is the powerhouse of the cell.
The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration. In this process, glucose is broken down in the cell's cytoplasm to form pyruvic acid, which is transported into the mitochondrion.
Answer:
The high specific heat of water caused by hydrogen bonding
Explanation:
Specific heat capacity of a substance is the quantity of heat required to raise the temperature of a unit mass of that substance by one degree Celsius (1° C).
Due to the hydrogen bonding present in water, water has a high specific heat capacity of 4184 Joules per kilogram. This means that, water has to absorb 4,184 Joules of heat for the temperature of one kilogram of water to increase 1°C. When compared to other substances such as metals, this is very high. For example, the specific heat capacity of copper is 385 Joules per kilogram which means that it only takes 385 Joules of heat to raise 1 kilogram of copper 1°C.
Therefore water, can absorb a large quantity of heat with very little changes in its temperature. This property of water helps the oceans and seas to serve as heat reservoirs by absorbing a large quantity of heat in hotter seasons and releasing these heat in colder seasons.
Well say the father had the genotype BB (dominant brown) and his mom had the genotype bb (recessive blonde).
If the boy got only one allele of brown hair and his phenotype is brown hair, then his genetic type is Bb
He is heterozygous (has two different alleles). But since brown hair is dominant, his phenotype is brown hair. But he does have the blonde recessive allele.
Hope this helps!
