Explanation:
There are eight major terrestrial biomes: tropical rainforests, savannas, subtropical deserts, chaparral, temperate grasslands, temperate forests, boreal forests, and Arctic tundra. Biomes are large-scale environments that are distinguished by characteristic temperature ranges and amounts of precipitation. These two variables affect the types of vegetation and animal life that can exist in those areas. Because each biome is defined by climate, the same biome can occur in geographically distinct areas with similar climates .
Answer:
D) Endocrine system
Explanation:
In some cases, the nervous system directly stimulates endocrine glands to release hormones, which is referred to as neural stimuli.

According to Mendel's experiment if we construct a punnet square the expected ratios should be 9:3:3:1. From our experimental results,
purple smooth = 75 ( 0.56) the expected is 0.56
white smooth = 28 ( 0.21) expected is 0.19
purple wrinkled= 24 (0.18) expected is 0.19
white wrinkled = 8 (0.06) expected is 0.06
From this results we plug the observable and expected values in a chi-square which is used to account for the differences between the expected and observable values. Then we conclude that the deviation of the observable value from the expected value is probably due to random sampling error and therefore we accept the hypothesis, such that the results are in consistent with the law of assortment.
A nerve is a bundle of fibers that receives and sends messages between the body and the brain. The messages are sent by chemical and electrical changes in the cells, technically called neurons, that make up the nerves.
