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.

In liver cells, the inner mitochondrial membranes are about five times the area of the outer mitochondrial membranes. What purpo
m_a_m_a [10]

Answer:

Option (C).

Explanation:

Oxidative phosphorylation may be defined as the process of the production of ATP molecule by the use of enzyme and transfer of electrons from one complex to the other complex.

The liver cells has five times large surface area of inner mitochondrial membrane than the outer membrane. This increases the surface area of the inner mitochondrial membrane that increase the rate of the oxidative phosphorylation. The complexes of the electron transport chain is located in the inner mitochondrial membrane.

Thus, the correct answer is option (C).

Describe what happens to organisms who optimum temperature zone is between 21°C and 32°C when the temperature rises from 21°C to
stiv31 [10]

Answer and Explanation:

The hypothalamus contains the central thermoreceptors which detect blood temperature as well as the thermoregulatory centre. The skin of organism contains peripheral thermoreceptors which detect the environmental temperature.

Increase in body temperature above the normal initiates the appropriate corrective mechanisms that include sweating, lowering of hair for mammals, vasodilation of superficial blood vessels and decrease in metabolic rates. This has an overall effect of causing the body temperature to fall and the normal body temperature is restored.

Sweat is secreted by sweat glands that evaporates from the surface of the body cooling the body as it absorbs latent heat of vaporization. Superficial blood vessels vasodilate so that more blood flows near the surface to encourage heat loss. Hair is lowered so that it lies against the body surface. This encourages heat loss from the body to the external environment.

In the laboratory, you have a beaker containing 100 milliliters (mL) of NaOH solution at pH = 13. Into this beaker, you carefull
romanna [79]

Answer:

d. The pH of the beaker`s contents will decrease.

Explanation:

Since the new substance is an acid and has a very low pH, that is 1. it will reduce a little bit the pH of the original base (NaOH). Some ions of hydrogen of the acid are going to react with the hydroxyl group of the sodium hydroxide to form water.

Since the differences of the volume is big, only a small part of the base is going to be neutralize, but at the end, the final pH of the solution is still going to be  a base.

Hope this information is useful.
