Answer:
Chloroplasts and Mitochondria both evolved in primitive microorganisms as
<u>they were able to make more use of available energy.</u>
Explanation:
Endosymbiosis involved the engulfing of smaller microorganisms by a larger one. These engulfed organisms and their hosts both had distinct genetic lineages. Mitochondria and Chloroplasts generate large amounts of energy in the form of high-energy ATP or adenosine triphosphate through several steps, the electron transport chains, Krebs and Calvin cycles.
On average, the net gain of ATP from mitochondrial respiration surpasses the energetic gain from the ATP made via glycolysis.
Still waters allow for sediments to settle down on fossils without disturbance. This gives the minerals in the sediments time to perfuse in the fossils and petrify the fossil. The sediments also settle on the fossils without disturbance, take the form of the fossil and get cemented forming molds.
Answer:the semipermeable membrane surrounding the cytoplasm of a cell.
Explanation:
Answer:
c) There will be a net movement of salt from side B to side A
Explanation:
According to the given information, the solution at side A is hypotonic to the solution at side B. The separating membrane is permeable to salt and would allow the movement of salt from the hypertonic side B to the hypotonic side A. Transport of substances down their concentration gradient is a passive movement and occurs from the region of higher concentration of the substance to that of its lower concentration.
Answer:
B. Light
Explanation:
Light is electromagnetic wave. Electromagnetic wave is a type of wave which does not requires medium for its propagation so that's why light travel through space from sun and sound can't because sound is longitudinal wave which requires medium for its propagation. Electromagnetic wave is also called transverse waves. In transverse or electromagnetic wave, movement of oscillation is perpendicular to the direction of the wave.
