What can be said about the diversity of life in the high tide zone compared to that of the low tide zone?
Airida [17]

Answer:

B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.

Explanation:

The high tide and low tide zones are located on the seashore as the ocean water merges with land.

High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.

There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.

Volgvan

Answer:

The human gene for your muscle protein is different from monkey muscle protein in 4 places and different from a chicken's gene in  25 places.

This is molecular biology, and this shows a little bit about evolution because it shows human, monkey and chickens share a common ancestor.

Explanation:

The example shows some features about biology. Molecular biology is focused on all the components and elements of molecular cells. In this case, analysing muscle protein and genes is considering this type biology.

DNA is the origin of every living cell on earth and is unique for every species. The analysis of protein's DNA is a determination of how distant or close species are.

There are many other ways to relate evolution to the different animals, species or cells. You can use fossil record, anatomy, reproductive isolation, embriology, among many others.

Positive and Negative feedback

Explanation:

In positive feedback, the released product in the process allows the increase in the product. For example- during the time of child birth, crevix due to more pressure allows contractions  and release of oxytocin. The hormone oxytocin causes more contraction.

In negative feedback, the released product causes decline in the level. For example, the temperature regulation mechanism, high temperature cause start sweating when there is temperature drop then low temperatures causes vasoconstriction and temperature increased again.
