Answer:
20 molecules of ATP
Explanation:
Krebs cycle or also known as Tricarboxylic acid cycle (TCA) is the second stage of aerobic cellular respiration which occurs in the mitochondria. In the kreb cycle, pyruvate, which was synthesized in the first stage of cellular respiration (glycolysis) is broken down into carbon dioxide (CO2).
However, in the krebs cycle, two (2) ATP molecules is produced per glucose molecule that enters cellular respiration. Hence, according to this question, If 10 glucose molecules enter the Krebs cycle, (2 × 10) = 20ATP molecules will be possibly produced.
Answer:
Force of repulsion.
By decreasing distance and increasing charge on both objects.
Explanation:
Force of repulsion is present between two negatively charged objects due to their same charge. if both charges are opposite to one another so it exerts force of attraction on one another. If we decrease the distance between two negatively charged objects so they exerts more force of repulsion on one another or by increasing power of charge on both objects also increases force on one another.
The correct answer is: B. A person spends one hour each day under the ultraviolet rays of a tanning bed.
The relationships between ultraviolet (UV) light and skin cancer are highly positive because it has been shown that indoor tanning bed use represents an avoidable risk factor for melanoma and non-melanoma skin cancer. UV light is a form of radiation that causes mutations in DNA by causing the chemical changes that alter the shape of the DNA. So, UV light is a potent mutagen and thus, tanning bed (source of UV light) can cause damage to the DNA in the surface layer of your skin after repeated or prolonged exposure. This might increase the risk for skin cancer.
Answer:
Nitrate
Explanation:
is the form of nitrogen most used by plants for growth and development. Nitrate is the form that can most easily be lost to groundwater. Ammonium taken in by plants is used directly in proteins. This form is not lost as easily from the soil.
False both the sun and the stars change and move around.
