Most scientists describe biodiversity in terms of the number of species that have been discovered and described in scientific jo

urnals. Roughly 1.8 million species have been described, although most scientists think there could be as many as 50 million species or more currently living on Earth. However, in the video, Craig Venter seems more interested in the total number of discovered genes (he gives a total number of 20 million genes in the video) than the total number of discovered species. Why is that?
a. For recombinant DNA technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene.
b. Identifying species takes too much time, and the rules state that new species must be identified and described in a scientific journal before their genes can be studied.
c. He is not interested in entire organisms, since the entire genome of each one must be sequenced in order to find anything useful.
d.The microbes that the team is collecting are actually all the same species, but they each carry a unique set of genes.

Answer:

The correct answer is option a. "For recombinant DNA technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene".

Explanation:

Genetic biodiversity and population genetics are modern concepts related to the total number of discovered genes, which in the video Craig Venter explains that are around 20 million. The number of discovered genes are very important for scientific development because for recombinant DNA technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene. Therefore, each new gene that is discovered or available, has the potential to be used in recombinant DNA technology developments.

If decomposers are removed from ecosystem,there would be no organic nutrients and all the dead plants would destroy the animals habitat. The ecosystem will be fill by plants and animal wastes as there will be no decomposition of waste material.

ANSWER ASAP PLEASE <br><br> What impact do trees have on the food web?
kati45 [8]

Answer:

Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.

what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency
Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
