The hormone calcitonin, which is produced by the parafollicular or C cells of the thyroid, has the opposite effect on blood calcium levels as does PTH. I hope this helps! : )
Forests would be able to survive a disease better.
<h3><u>
Explanation:</u></h3>
Many studies have taken place for many years to determine what type of ecosystem can best survive diseases effectively. A recent study has concluded that the forests are the viable ecosystem which can survive a disease better then any other ecosystem; followed by grasslands as the second best.
The study states that the chances of forests are better as the ecosystem contains many different species of trees and plants. The mix of several species in an ecosystem helps in surviving climate changes, pests and severe diseases. According to the study, the diversity of different biological species have a better rate of production than an environment which has only one species in it. The biodiversity will help produce the amount of energy that would best suit the needs of population.
I'm pretty sure that it's C. I'm not quite sure though.
Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).
