The solution would be D. Pyruvic acid is produced during glycolysis and travels from the cytoplasm and enters the mitochondrion.
The answer is D. This is referred to as reflex reaction. Reflex is the instantaneous and involuntary reactions to a stimuli. Reflex arc does not pass through the brain so the reaction time is shorter than normal. This is a adaptation to increase survival.
<span>Increasing rates of work will increase the energy demand of the body. To fulfill the energy needs, the heart needs to pump more blood.
The rate of blood pumped by heart is known as cardiac output while stroke volume is the amount of blood pumped each contraction. It is calculated by: heart rate x stroke volume
The easiest variable to changed to increase the cardiac output would be heart rate. When a person increases his </span><span>rates of work, the heart rate will be increased to increases the cardiac output so the heart can supply the energy needed.</span><span>

Answer:
<em>The correct option is 'this guinea pig could be homozygous dominant (HH) or heterozygous (Hh).'</em>
Explanation:
When both the alleles of a gene are the same then they are termed to be homozygous. If a gene possesses two different types of alleles then it is termed as heterozygous.
A dominant allele is the one which can suppress the effect of a recessive allele. A recessive allele is the one which gets masked by the dominant allele.
For a dominant trait to occur, an organism can either be homozygous dominant for that trait or it can be heterozygous for the trait.
Answer:
The correct answer is - homologous chromosome exchange genetic information during prophase I.
Explanation:
Genetic variation or diversity in the offspring of an organism comes from the process of crossing over which takes place in gametes formation during meiosis.
In prophase I of meiosis I, the recombination or crossing over takes place in which the homologous chromosomes pair joins with a structure called synapsis, and segments or the arms of the non-sister chromatids are exchanged during the production of the gamets.
