<span>Beneficial traits are inherited traits (they may be phyical, biochemical, or behavioral) which increase an organism's fitness. Fitness is the technical term in biology for an organism's ability to reproduce itself, compared to other organisms. A beneficial trait, then, may either (1) increase the number of times which an organism reproduces, (2) increase the number of offspring which an organism has per reproductive act, or (3) increase the fitness of individual offspring. These three are not, of course, mutually exclusive. </span>

That are beneficial traits you ask?
<span>Beneficial traits are inherited traits (they may be phyical, biochemical, or behavioral) which increase an organism's fitness.

These three are not, of course, mutually exclusive.

It should be noted that no trait is intrinsically beneficial; the benefit of a trait can only be determined by first looking at (1) the other traits which an organism has and how they might react with the trait under discussion, (2) the other organisms in the environment, and (3) the other non-living aspects of an organism's environment.

Thus, having one copy of the sickle cell anemia gene from each parent gives you a deadly disease, which is NOT beneficial; however, having a copy of this gene from just one parent provides increased resistance to malaria. In most parts of the US, this is not useful at all; in many parts of southern India and Africa, however, it is extremely useful. Thus, a trait can only be called beneficial or not with regard to its context.</span>

Which of the following statements about telomerase is false? Which of the following statements about telomerase is false? Telome

zmey [24]

Answer:

Telomerase acts to elongate the 3' end of linear DNAs.

Explanation:

The 5' ends of the linear DNA can not be replicated by DNA polymerase due to the absence of free 3' end to be elongated. This is prevented by the action of telomerase enzyme which contains both RNA and protein components. The RNA component of the telomerase is 150 nucleotides long.

The telomerase enzyme elongates the 3' end of the template strand by using its inbuilt RNA template. Since it uses an RNA template to make the DNA copies, it is a reverse transcriptase. Repeated translocation and repositioning of the enzyme elongates the 3' end of the template DNA.

The RNA primase makes the RNA primer at the end of the new telomere strand which is then elongated by DNA polymerase. DNA ligase seals the nick. In this way, telomerase serves to prevent the loss of 5' ends of linear DNA in successive rounds of DNA replication.

Prokaryotic cells generally have a higher surface area to volume ration than eukaryotic cells.

charle [14.2K]

Answer:

True.

Explanation:

Prokaryotes and eukaryotes shows various similarities as well as differences among themselves. The eukaryotes have well defined nucleus whereas such nucleus is absent in prokaryotes.

Prokaryotes are much smaller in size than eukaryotic cells. The small area has large surface area to volume ratio. This ration helps in the process of diffusion and metabolism in prokaryotes. Due to their small size, prokaryotes have large surface area to volume ratio than eukaryotic cells.

Thus, the correct answer is option (a).

Once inside muscle cells, the oxygen can either bind to myoglobin (a protein like hemoglobin that enables muscle cells to store a small amount of oxygen) or enter the mitochondria to be used in the elec- tron transport chain to accept the H+ ions produced by the oxidation of carbohydrate and fat.
