Scientists found that the first living things were likely prokaryotic because eukaryotic are evolved from the prokaryotic only.
<h3>What do you mean by Natural selection?</h3>
Natural selection may be defined as favorable variations that assist the organisms to survive and reproduce in a particular habitat.
Individuals that are better suited to their environment are likely to have more offspring and pass their genetic material on to future generations. This theory is referred to as Natural selection.
Scientists hypothesize that oxygen began to accumulate in the Earth's atmosphere after the appearance of living things with the ability to Photosynthesize.

Answer: (c) It generates ATP, which cells can use to do work.
(d) It generates chemical gradients, which have potential energy.
Explanation:
The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.
Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)
In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.
Answer:
storage of sugar is no a typical function of a cell membrane
Explanation:
Answer:
Muscles cells
Explanation:
Energy is required by all the cells but muscle cells more energy. As muscle cells help in body movement so they continuously contract and expand which requires a large amount of energy and this energy is provided by ATP.
Mitochondria are responsible for making ATP in the cells and the evidence that muscle cells require most ATP is the presence of more mitochondria in muscle cells than other body cells which helps muscle cells to provide more amount of ATP or energy.
Liver cells also contain a large number of mitochondria because they need energy for regeneration.
