Answer:

Ionizing radiation

Explanation:

Ionizing radiation is a method of sterilization that can be used to sterilze material that can not withstand some higher temperature and cannot be exposed to water for sterilization.

It is form of energy that is released when atoms is released to move in the form of electromagnetic waves or particles. such as; X-rays or Gamma rays particles,neutrons, alpha or beta.

It could be dangerous if atoms inliving cells is exposed to it because the cell will be ionized, and it can lead to death of cell , or the mutatation of cell and can lead to cancer. Although not all cells are affected by ionizing radiation.

1)X-Rays, X-rays move in the form of photons energy .

2)Alpha Particles. Alpha particles have less penetration than gamma ray they don't penetrate skin as x-rays

3)Beta Particles, they are particles of electrons which are faster than alpha particles.

Which of the following statements is false?
Vilka [71]

Answer:

A Carbon can be stored in the body fat of a salmon.

Explanation:

Salmon can be seen as food which are a classified as an oily fish in which they tend to have rich content of protein as well as omega-3 fatty acids.

Therefore this statement about carbon "A Carbon can be stored in the body fat of a salmon" is FALSE because CARBON can move within the cells of an organism, they are degraded by amino acids and Carbon can remain in soil bacteria for a long time.

1.CARBON can move within the cells of an organism:Carbon is found in all living things because they tend to constantly move  through  living  organisms such as the oceans, the atmosphere as well as the Earth's crust.

2.Carbon are degraded by amino acids because they can help to give rise to ketone bodies or fatty acids.

3.Carbon can remain in soil bacteria for a long time because Living organisms always contain a fair proportion of the element carbon which is why  soil organic matter can be 50 to 58% carbon by dry weight in which  some of it can remain  in the soil for a long period of time.

Thus CARBON can as well be found in an environment where living organisms breathe and they are also in organic matter in the soil and rocks.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
galina1969 [7]
The answer is C) 3/4

Let's analyze separately each of the traits:

Parental generation: AA x Aa
F1 generation:       AA AA Aa Aa
So, all progeny will <span>phenotypically resemble the first parent.

</span>Parental generation: BB x bb
F1 generation:       Bb Bb Bb Bb
So, all progeny will <span>phenotypically resemble the first parent.
</span>
Parental generation: Cc x Cc
<span>F1 generation:       CC Cc Cc cc
</span>Only 3 (CC, Cc, Cc) out of 4 progeny will <span>phenotypically resemble the first parent.

The genotypes for first two traits will not affect </span>phenotypical resemblance to the first parent. So, it only counts the third trait, for which the chance to have progeny that <span>phenotypically resemble the first parent is 3/4.</span>
