Very simply, when using metagenomics, distinctions between bacterial species are based upon what?
Alexeev081 [22]
Metagenomics is the study of genetic material recovered directly from environmental sample. Its field has been responsible for substantial advances in microbial ecology, evolution, and diversity over the past 5 to 10 years and many research laboratories are actively engaged in it now. Using metagenomics, the distinctions between bacterial species are based upon the comparison of DNA nucleotide sequences of different bacterial species.

A summer squash plant that produces disc‑shaped fruit is crossed with a summer squash plant that produces long fruit. All of the
ivanzaharov [21]

Explanation:

In the given question,

suppose allele A and a determines the color of the fruit whereas allele B and b determines the shape of the fruit.

The genotype for white, disc shape fruits is- AABB

the genotype for yellow, long fruits is- aabb

F1 progeny will be- AABB x aabb

                                 AaBb

F2 cross-    AaBb    x    AaBb

                      AB          Ab          aB           ab

      AB        <em>AABB       AABb    AaBB       AaBb</em>

      Ab       <em>AABb       AAbb     AaBb       Aabb</em>

      aB      <em>  AaBB      AaBb      aaBB       aaBb</em>

      ab        <em>AaBb       Aabb      aaBb      aabb</em>

          The genotype of F2 cross are-

1.  9/16 A- B- disc-shaped (like F1)

2. 3/16 A- bb spherical

3. 3/16 aa B- spherical

4. 1/16 aa bb long.

vfiekz [6]

Answer: 62.9%

Explanation:

Figure one is not available so I cannot answer the first part of the question.

The second part however, has the relevant information required.

The percentage of large animals eaten by lions from the total amount of biomass eaten by lions is:

= Weight of large animals / Total weight of animals eaten by lions * 100%

= 110,000 / 175,000 * 100%

= 62.9%
