Answer:
Protein is the important biomolecule that acts as building block of the protein. Proteins are inserted into the biological membrane and consists of transmembrane and integral membrane proteins.
The alpha helices and beta sheets are present in the bio membrane. The organism living at low temperature has high alpha helices and low beta sheets because alpha helices has high mobility, less rigidity and makes enzyme active at low temperature.
Answer:
C
Explanation:
Extremophile live in "extreme environments" under high pressure and temperatures.
The centromere is <span>the region that joins the two sister chromatids, or each half of the chromosome. In prophase of mitosis, specialized regions on </span>centromeres<span> called kinetochores attach chromosomes to spindle fibers.</span>
Answer:
The most appropriate answer would be option B.
The flaw in their reasoning is that they compared different molecules in a different set of organisms.
For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.
In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.
Answer:
DD or Dd
Explanation:
Dimples is the dominant trait (D). Your friend has dimples so that means he or she should have at least one allele of the dominant trait to express that trait. So your friend would either be homozygous dominant (DD) or heterozygous dominant (Dd). Notice that there is a recessive allele in the second. Even with that present, dimples would be still expressed.
