The resurrection fern (Pleopeltis polypodioides) grows on the bark of southern live oak trees (Quercus virginiana). Resurrection

ferns that grow on the underside of branches receive less water than those growing on the topside and, therefore, have a fitness of only 0.28. How many of these ferns will be non-reproducing?
Select one:

a. 52%

b. 72%

c. 80%

d. 28%

Answer:

Option B

Explanation:

In biology, fitness refers to the ability of an organism to survive, reproduce, mate and support evolution through gene transfer. A fitness of 0.28 signifies that only 28 percent of a given population are fit physically and able to reproduce while the remaining 72 % are unable to mate and hence cannot reproduce  and contribute towards gene flow and evolution.

Hence, option B is correct

Describe the role of the carrier molecule nadp in photosynthesis
Eduardwww [97]

Answer:

The high energy electrons from chlorophyll to other molecules are transferred by this molecule.

Explanation:

NADP is an important molecule which is used in the production of energy in the form of ATP. During the process of photosynthesis it acts as a universal electron carrier. It accepts electrons and hydrogen atoms to form NADPH. NADPH then moves to the other location of reactions and there it donates the energy stored in bonds along with hydrogen and electrons to other molecules and again becomes NADP.

Paul [167]

Cladistics is a way of grouping the related branches based on sharing derived characters within the group. However these characters are not found in other species except by convergence. Phylogeny is a way of tracking evolutionary relationships based on shared characters based on artificially defined levels of taxonomy.

Which statement best describes the role of gene expression in cells?
maw [93]
The answer is <span>To become specialized, cells need to control the production of proteins coded for in their DNA.

All genetic information in a cell's DNA is not fully expressed at all times. On the contrary, in different cell lines, different DNA segments are expressed at different times. Some genes are active in unspecialized cells and later deactivate, some are activated only in specialized cells, for example. These are facultative genes which are active when needed, unlike constitutive genes which are expressed continually. Therefore, <u>t</u></span><span><u>o become specialized, cells need to control the production of proteins coded for in their DNA. </u>DNA segments, however, remain in cell and are not destroyed. Also, during the mitosis, all genes are passed, not only required genes.</span>
