Answer:
Cell phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a person is exposed to depends on the frequency of the signal and the amount of time they spend on the phone. The Federal Communications Commission (FCC), the International Agency for Research on Cancer (IARC), and the American Cancer Society (ACS) all agree that more research is needed to determine the possible health effects of cell phone use. So far, there is no scientific evidence that proves that cell phone use causes cancer. Some studies have suggested a possible link between cell phone use and cancer, but more research is needed to confirm these results. The ACS does not recommend limiting cell phone use because the risk of cancer is still unknown.
Hope this helps!
Explanation:
First, we will elaborate the terms that are being used.
Heterozygous:
This means that the organism has a set of alleles which are different from one another. One copy may be for the dominant trait and the other for the recessive one.
Homozygous:
The organism has two copies of the same allele
Dominant:
An allele that will express itself even if only one copy of it is present. These are usually represented by capital letters.
Recessive:
An allele that requires both copies to be expressed. These are usually represented by lower-case letters.
A: Heterozygous
B: homozygous recessive
C: Homozygous dominant
D: Homozygous recessive
E: Homozygous dominant
Answer:
it depends on changes in gene expression
A group of tissue that work together is a organ
The movement in phloem is bidirectional, whereas, in xylem cells, it is unidirectional (upward).
