Duplication of a segment of a chromosome would result in _______. see section 16.4 (page 344) .
Svetlanka [38]
Duplications are repeated segments of genetic materials that result from unequal crossing over during meiosis or through a replication error prior to meiosis. They usually occur when homologous pairs do not line up correctly or in chromosomes with a lot of repeat sequences. Duplication of a segment of a chromosome would result in Genetic variability during evolution due to gene duplication.

The amount of energy at trophic levels one and four in an ecosystem is indicated by the numbers.
nexus9112 [7]

Answer:

1100

Explanation:

There is 10% of total energy in each increasing trophic level.                    10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.

1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.

1,000 + 100 units of combined energy would be 1,100 units of energy.

Hope this helps!

Which of the following statements correctly describes the difference between the leading and the lagging strands of DNA during D
Mrrafil [7]

The answer is; A & C

The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.

What are the differences between aggregate fruit and multiple fruit ​
Dmitry_Shevchenko [17]

Answer:

Aggregate fruit is a fruit that develops from several ovaries forming one flower. An example of an aggregate fruit is a raspberry. Multiple fruit is fruit that develops from a cluster of flowers, and each flower produces a fruit, which turns into a mass of a singular fruit. An example of multiple fruit is a pineapple. Each "cube" of a pineapple is a separate fruit formed from a single flower, yet the pineapple as a whole is one mass of pineapple.
