Answer:
The correct option is e. tissue composed of several layers of flat cells resting on a basement membrane
Explanation:
When you look in the miscorscope the structure of a stratified squamous epitellium, you can see several layers of flat cells resting on a basement membrane. In this kind of epitellium not all cells are flat, some have a different shape. As you can imagine, only one of the layers are in touch with the basement membrane.
Another feature of the stratified squamous epitellium is that it can have keratin or not. Examples of this epitellium are found in skin or esophagus.
The thing that makes a thing living is that they are made of cells, use and obtain energy, grow and develop, and living things respond to their enviroment.
Options for the question are not given. They are as follows:
a. arg or lys
b. ala
c. thr
d. leu or ser
e. Only termination codons
Answer:
d. leu or ser
Explanation:
Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.
If first position is changed in each codon:
CCT = TCT (UCU)
CCC = TCC (UCC)
CCA = TCA (UCA)
CCG = TCG (UCG)
These codons produce Serine amino acid.
If second position is changed in each codon:
CCT = CTT (CUU)
CCC = CTC (CUC)
CCA = CTA (CUA)
CCG = CTG (CUG)
These codons produce Leucine amino acid.
Hence, out of the given options, option d. leu or ser is correct.
The best answer would be:
A membrane bound nucleus
<u>Here is more about the question:</u>
There are three domains in the classification of organisms and they are Eubacteria, Archaea, and Eukarya. What makes Eukarya different from the other two is the presence of a nucleus in the cells. Among the remaining two, Archaea is more closely related to Eukarya than Eubacteria.
