Answer:
The correct answer is "The nervous system transmits pain, while the endocrine system elicits the fight or flight response".
Explanation:
One of the roles of the nervous system is to transmit pain to alarm the body that something is going on and that it acts accordingly. The nerve pathway is the one that carries the message of pain from the affected area to the spinal cord and up to the brain. On the other hand, the endocrine system is the one that elicits the fight or flight response. During stressful conditions, the adrenal glands of the endocrine system release epinephrine and norepinephrine that acts during the fight or flight response.
Answer:
b. average heterozygosity
Explanation:
From the available options:
a. nucleotide variability
b. average heterozygosity
c. average number of loci
d. geographic variability
Nucleotide variability represents a form of genetic variation that occur as a result of difference in nucleotide sequence of deoxy ribonucleic acid.
The locus is a region on the chromosome where genes are located. Average number of locus thus refers to total number of loci per total number of individuals in a population.
Geographic variability refers to difference in genetic traits across the various geographical distribution of a population.
Average heterozygosity is the percentage or proportion of heterozygous individuals for a trait within a population. It is a common measure of genetic variation in a population.
When a mutation occur within a population and this leads to the introduction of a new allele at a locus for which some individuals within the population are homozygous, it will directly affect the average heterozygosity of the population because more individuals will lose their homozygosity and become heterozygous.
<em>The correct option is b.</em>
Food handlers who does different cutting surfaces base on cutting raw vegetables and raw poultry, is trying to prevent contamination as doing this prevents food from being mixed and from being contaminated. It is also a way of having the food to be prepared properly and in a more sanitized way for people to eat.
Fairly sure that would be secondary succession.
