If a natural disaster caused all warbles to go extinct, why would the natural disaster not kill all living organisms?
likoan [24]

Answer:

Living organisms that are able to adapt to the environment (natural disaster) will increase in number while the ones such as warbles who can't adapt will die and go into extinction.

Explanation:

Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.

Simply stated, natural selection entails the survival of the fittest. Therefore, the species that are able to adapt to the environment will increase in number while the ones who can't adapt will die and go into extinction.

Additionally, due to genetic variation within populations, some living organisms have a better chance of possessing good or beneficial traits being passed from the parent organism to her offsprings which enables them to survive a natural disaster.

Hence, if a natural disaster caused all warbles to go extinct, the natural disaster may not kill all living organisms due to natural selection.

Tumors of the parathyroid gland often result in secretion of excess parathyroid hormone. Considering the function of this hormon
Luda [366]

Answer:

Parathyroid hormone increases the level of calcium while calcitonin hormone  decreases the level of calcium in the blood.

Explanation:

Parathyroid hormone is a type of harmone which is responsible for balancing calcium in our body. When the calcium level lowers in our body, parathyroid hormone is secreted and calcium is absorbed from the bones and fullfilled the requirement of the body. If the tumor secreted calcitonin hormone instead of parathyroid hormone, the calcium level in the blood is lowered because it acts to the opposite of parathyroid hormone.
