Since living organisms require energy and both survival and reproduction... the sun provides the energy for photosynthesis. Cells need sugar as a sources of energy. The cellular respiration is the synthesis of ATP using energy that is being released by the breakdown of sugar to carbon dioxide and water.
<u>Answer:</u>
<em>Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk.
</em>
<u>Explanation:</u>
<em>The leaves of touch me not plant stay upright due to turgor pressure. </em>It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.
When there is an external disturbance , parts of the plant releases certain chemicals including potassium ions that causes water to diffuse out of cells. <em>This releases the turgor pressure and causes the leaves to shrink. </em>
Answer:
C. They can grow to larger populations more quickly
Explanation:
Bacteria are the <u>key entities</u> of <u>biogeochemical cycle</u>s (Nitrogen, Carbon, Oxygen, etc.) on Earth. The strength of these cycles is typically achieved when they can multiply faster in a relatively <u>short time period</u>. If all bacteria on Earth start reproducing via sexual means only, then many of the biogeochemical cycles would take forever, thus <u>generating nutrients at a slower rate</u>. Since higher organisms (e.g. eukaryotes) depend on the abundant supply of nutrients, the overall life on Earth would be compromised to a larger extent in the absence of sufficient nutrients supply. Thus, it is <u>beneficial for all forms of life that bacteria reproduce mainly via asexual means</u>.
PS: A simple bacterium can produce millions of copies in 24 hours period.
This cycle is called the carbon cycle.
