Answer:
It is important for scientists to study other planets because <u>it helps them learn more about Earth's history.</u>
<u></u>
Explanation:
In the expanse of the space-time continuum of the universe there are many celestial bodies from stars to planets that all formed at different times hence have different ages and are at different stages of formation.
Studying other planets helps reveal alot about our own planet, its history and its formation. By observing younger earth-like planets, scientists could understand how the earth looked like in its younger years and how it was formed.

Answer:
proteins called expansins
Explanation:
The complete question is :
<em>According to the acid-growth hypothesis, auxin causes increased acidity in cell walls, which then activates ____ that disrupt(s) bonds between cellulose microfibrils, allowing cell expansion.</em>
<em>a. a membrane potential </em>
<em>b. an mRNA </em>
<em>c. AUX1 transporters </em>
<em>d. K+ ions </em>
<em>e. proteins called expansins</em>
<em></em>
- The acid growth hypothesis explains the growth of cells and organs in the plants.
- According to this hypothesis, the plant hormone auxin causes induction of the H+ proton extrusion into the apoplast which leads to the activation of expansin which a pH-sensitive protein.
- Expansin is responsible for wall stretching and relaxation and causes hydrolysis of hydrogen bonds and thus helps in cell expansion.
