Answer: Weak.
Explanation:
The complete question is:
Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?
Well, here we have beta decay.
Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)
Then the correct option is the second one, weak.
Answer:
B) harvest photons and transfer light energy to the reaction-center chlorophyll
Explanation:
The antenna pigment molecules form a complex which is known as the light-harvesting complex.
There are three antenna pigment molecules present in plants :
1. chlorophyll b
2. xanthophylls
3. carotenes
In one complex there can be 250 - 400 pigment molecules present which acts collectively to absorb energy and transfer it to the reaction center which consists of the chlorophyll.
This reaction center is responsible for capturing light energy in the form of chemical bonds.
Answer: glucose molecules.
Explanation: cellular respiration is a process by which glucose molecules are broken down in the presence of oxygen into carbon dioxide and water with the concomitant release of energy in form of ATP. The equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2 + 6H2O + Energy.
Cellular respiration is divided into four stages:
1). The breakdown of glucose into two molecules of pyruvate.
2). The conversion of pyruvate to Acetyl CoA.
3). The oxidation of acetyl CoA in the Krebs cycle to produce ATP, FADH2 and NADPH and;
4). The oxidation of FADH2 and NADPH in the electron transport chain to generate more ATP.

If the resulting daughter cells are too damaged to undertake further cell divisions, the mutation would not be propagated and no harm comes to the organism
