Their would be alot of mutations in genes. Also, we wouldn't be able to function properly.
Answer:
The correct answer is D) Infundibulum
Explanation:
The Infundibulum, also regarded as the Pituitary Stalk is an area of the brain that appears like a v-shaped stem which connects the hypothalamus and the posterior pituitary gland.
It functions as a medium by which hormones are conveyed from the hypothalamus into the pituitary gland, and on to the veins.

Answer:
Three major hormones (PTH, vitamin D, and calcitonin) interact to maintain a constant concentration of calcium, despite variations in intake and excretion.
Explanation:
The second major hormone involved in the regulation of calcium metabolism and skeletal remodeling is vitamin D, which includes cholecalciferol (vitamin D3) of animal origin, as well as ergocalciferol (vitamin D2) of plant origin.
Answer:
I believe the options are:
1) Present day species developed from earlier species
.
2) Some species die out when environmental changes occur
.
3) Complex organism develop from simple organisms over time
.
4) Change occurs according to the needs of an individual.
The answer is 4) Change occurs according to the needs of an individual.
Explanation:
Theory of Evolution:
- By definition, evolution is the process of change in an individual's/organism's characteristics over time. Evolution occurs through mutations in the genetic information or DNA of an individual.
- The theory of evolution states that all organisms change over time and are descendants of a single common ancestor. Species adapt to the changing environment by introducing variations in their DNA over millions of years. Harsh environment conditions eliminate organisms that cannot adapt to the changing environment and only the fittest survive. This is called natural selection.
- This process, occurring over millions of years, results in the formation of an entirely new species.
- The theory of evolution is contrary to the concept of Lamarckism or inheritance of acquired characters which states that characters that an organism acquires during its lifetime can be passed on to its offspring.
