Suppose two people are exposed to equal doses of radiation (equal number of rads) inside their bodies. Suppose that the first pe

rson is exposed to alpha radiation, while the second person is exposed to protons. How many times worse is the biological risk for the first person than the second as a result of radiation weighting?

Answer:

10 times

Explanation:

Radiation weighing factor is a measure of the effectiveness of per unit dose of the given radiation that how much harmful it is for a biological tissue. In other terms it can also be defined as it is the ability of radiations to transfer the energy to the body.

For different particles it has different value. Some of the values are listed below -

Photons  = 1

Electrons  = 1

Protons  = 2

Alpha particles, fission fragments, and heavy ions  = 20

Neutrons = 2-20

Thus we can see that the value for alpha particles is 20 and for protons it is 2. Thus for alpha particles it is 10 times more than the protons.

Answer: C) the genes of this phage were made of DNA.

Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.

Can someone please help on these two question Please I don't get this at all I'm really confused
marissa [1.9K]
Alleles are letters that represent dominant and recessive traits.

A capital letter represents a dominant trait
A lowercase letter represents a recessive trait.

Dominant traits over shadow the recessive ones. This is known as complete dominance.

Referring to your questions let's us the alleles HH, Hh, and hh for the height of the pea plants.

But what do those letters mean?

HH = homozygous dominant (Tall)
Homo means same.

hh = homozygous recessive (Short)

Now this is different: here's Hh.
There's a capital AND lowercase letter.
This means that the plant carries the gene for tall and short plants, and can pass on either trait to the offspring.

BUT the dominant always over shadows the recessive. So Hh is a tall plant.

Hh = heterozygous (hybrid) (Tall)
You can interpret hetero meaning different.

Now I hope you're with me!

For question two it asks if a short plant can ever be a hybrid.
Referring to what I just said, that answer would be no.
Because there is no dominant trait to over shadow the recessive.

And short plants have the hh alleles, and they are homozygous NOT heterozygous (hybrid).

I hope this helps, and makes sense! If you have any questions please let me know. Genetics can be confusing.
