Contrast the significance of the cone of increasing diversity

Answer:

The history of human cultures is frequently marked by a distinctive pattern of evolution that paleobiologists term diversification and decimation. Under this process, fundamentally new socioeconomic systems appear during periods of dramatic cultural diversification,typically through cultural cladogenesis. Significant diversification episodes come about under conditions that favor group economic success under effective or geographic isolation.Typically short-lived, they are often followed by abrupt decimation under more competitive economic conditions. Regional archaeological sequences, viewed from this perspective, suggest that cultural evolutionary trends are strongly conditioned by historical contingency, though general evolutionary processes are continuously active; the emergence of new systems may be contingent on economic opportunities associated with niche reorganization; and severe competition such as that associated with demographic stress will generally favor decimation.

The wild-type color of horned beetles is black, although other colors are known. A black horned beetle from a pure-breeding stra
Kisachek [45]

One hypothesis that explains the result is : A) Two genes are involved with  12:3:1  epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.

Explanation:

  • This is a case of Dominant Epistasis.
  • When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
  • In the given case black :brown: green ratio is approximately equal to  12:3:1.
  • Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
  • Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
  • When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.

Packages proteins made by the ribosomes​
stealth61 [152]
It is sub-classified as a rough, or granular ER, and a smooth or agranular ER. The rough Endoplasmic reticulum is lined with ribosomes and modifies and packages proteins that have been produced by the ribosome. In skeletal and cardiac muscle it is known as the sarcoplasmic reticulum.

Answer:

It contains Uracil (U) instead of Thymine (T).

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Explanation:

Primers:

Primers are a short sequence of RNA. These sequences attached to the 5' end are the requirement of DNA polymerase to start the process of replication.

Primer removal:

After replication, these short fragments of RNA are removed to replaced with DNA from the newly synthesized DNA strand.

Reason for primer removal:

This is because of their uracil nucleotide which is absent in DNA. Instead of Uracil DNA contains Thymine nucleotide.

Best Answer:

Because It contains Uracil (U) instead of Thymine (T).
