Answer:
Genetic variation is the difference in DNA among individuals or the differences between populations. There are multiple sources of genetic variation, including mutation and genetic recombination.
Explanation:
Answer:
Eukaryotes are alive, but Prokaryotes aren't.
But both contain a <em>plasma membrane</em>, <em>cytoplasm</em> and <em>ribosomes</em>. Hope this helps!
Answer:
Energy is stored in <u>glucose</u> molecules <u>C6H12O6</u>
<u />
Explanation:
Producers make sugars stored as monomers bonded together to form polysaccharides, long chain hydrocarbon molecules as a result of the process of <u>photosynthesis</u>. These molecules, like the monosaccharide glucose, store converted solar energy as stable chemical energy in covalent bonds. In covalent bonding, the elements share electrons with each other.
These high-energy bonds are stable and not easily destabilized or broken. The energy is retrieved the the process of respiration in the mitochondria.
Glucose is broken down, while energy is transferred to bonds between ADP and inorganic phosphate, to produce ATP (adenosine triphosphate).
Eg. for aerobic respiration...
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy
One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.
Normal cells are characterized by their ability to regulate cell division during the cell cycle.
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.
