Epithelial cells are the cells that arise from the upper layer of the body such and form the surface of the body for example skin, organs, blood vessels and other. They serve as a barrier in the outer environment and the inner side of the body. It helps to protect the body from microbes like viruses.
The three main characteristics of these cells are; specialized cell-cell junctions
, innervated
, highly cellular with little extracellular matrix but these cells are not vascular.
I think the answer is <span>epithelial and connective tissue
Muscle cells need much energy to moves its fiber, so it must be on a highly vascularized area. The nervous system also needs a blood supply to works. In fact, the brain cells use the highest amount of energy. Epithelial and connective tissue doesn't need much energy because its main function is to protect other tissue. It also has densely packed cells to make it sturdy.</span>
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p

P | PP | Pp |

p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
Allele. An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. ... An organism in which the two copies of the gene are identical — that is, have the same allele — is called homozygous for that gene.
<em><u>With your group, use a complete sentence to write a rule for how the bases are arranged in the ladder model of DNA. ... The complementary base-pair rule states that adenine and thymine form pairs across two strands, and guanine and cytosine form pairs across two strands.</u></em>
