It would be B. the mixture became warm, as a change in temperature is certain evidence that a chemical reaction has taken place.
Answer:
The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.
Explanation:
Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.
Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:
- <em>The outermost lamina is called the </em><em>ectoderm</em><em>, which can give rise to nerve tissue and part of the skin tissue.
</em>
- <em>The </em><em>mesoderm</em><em> is the middle lamina, and from it vascular, bone, muscle, and joint tissue can develop, as well as tissues of excretory and reproductive organs. </em>
- <em>Endoderm</em><em> corresponds to the internal lamina, forming in great part the mucous membrane of the organs of the digestive system.
</em>
It is true, then, that <u>In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body</u>.
I think its called a peer view
hope this answer is right
The answer is that It would die out
Punctuated equilibrium occur when the environment is rapidly changing eliminate.
Answer: Option B
<u>Explanation:</u>
Punctuated equilibrium generally occurs when a sudden massive change occurs in the regular stream. The organisms are forced to adapt themselves to the new environment at the earliest and this process is induced to maintain the equilibrium.
This is the reason why you find an abrupt change in the species without undergoing slow morphological changes. Hence no intermediate forms can be found if you would examine the fossils. Hence to conclude when a species under rapid change to evolve itself to suit the environment it is punctuated equilibrium.
