Biology
1 answer:
mel-nik [20]3 years ago
8 0

Answer:

Sequence a DNA fragment.

Explanation:

Dideoxyribonucleotides may be defined as the DNA molecule that lacks hydroxyl group at 2 and 3 position of the pentose sugar. These molecule are important in the molecular biology.

The sequencing of a DNA fragment means to determine the sequence of the nucleotides in a DNA molecule. The  dideoxyribonucleotides is used to tag the target DNA fragment and known the sequence of the target DNA molecule.

Thus, the correct answer is option (C).

This means that each dominant allele "adds" to the expression of the next dominant allele. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles.

In a food chain 200 kg of wheat is fed on by 18 kg of mice which in turn are eaten by 1kg of hawk. What is the percentage energy
Nikolay [14]

Answer:

0.1% of energy

Explanation:

Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.

From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.  

At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.

If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.

10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)

<em>TL = Trophic level           </em>

The intermediate disturbance hypothesis predicts that species diversity will be ______when the frequency and/or intensity of dis
alukav5142 [94]

The intermediate disturbance hypothesis predicts that species diversity will be highest  when the frequency and/or intensity of disturbances are intermediate

Explanation:

The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
