Scientists have found that extracellular matrix component may induce specific gene expression in the embryonic tissues such as the liver and testes. For this to happen, there must be a direct communication between the extracellular matrix and the developing cells. The Integrins of transmembrane protein would most likely be involved in this kind of induction.
Integrins are the main principal receptors used by the cells of animal to bind to the matrix of extracellular. They are heterodimers and they function as transmembrane linkers between the actin cytoskeleton and the extracellular matrix. A cell can regulate the sticky activity of its integrins from within.

The theory of evolution proposed that a series of catastrophes or mass extinctions followed by repopulation could explain why species change over time
Answer:
When an offspring's trait is identical to the parent and it's siblings, we say that it is a
n inherited trait.
Explanation:
Inherited traits are when you get features from your parents which are passed on to your genes.
Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
- A) ATP is used to lower the activation energy in enzymatic reactions.
<h3>How does ATP affect enzyme activity?</h3>
Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP. When cells convert glucose and oxygen into carbon dioxide and water, they use 2 molecules of ATP as activation energy and gain 36 to 38 molecules of ATP in return. Without enzymes, this would not be possible.

Answer:
Archaea
Explanation:
Most extremophiles are microorganisms (and a high proportion of these are archaea), but this group also includes eukaryotes such as protists (e.g., algae, fungi and protozoa) and multicellular organisms. Archaea is the main group to thrive in extreme environments.
