<span>Birds and dinosaurs show homology because they are closely related, such as pigeon and tendon. They have different types of wings, but birds have evolved from dinosaurs. Unlike other species such as insects, which can be a homoplasy or a homology. This is due to its world and complexity.</span>

A high fever causes an enzyme to lose its three dimensional structure and function. which bonds are broken when a protein denatu
marta [7]
The appropriate response is hydrogen bonds. Fever is an adjust of gainful and destructive impacts. High fevers can have a tendency to skew the adjust toward the destructive. 
The reality of the matter is that protein optional structure (generally hydrogen bonds) start to denature when moving toward 41 degC (106 degF), however energy likewise change. Energy is a quite major ordeal, even a little temperature move can altogether affect the speed of a response or connection.

A hybrid allotetraploid species (2n1 + 2n2 = 60) was backcrossed to one of the suspected parents (2n1 = 30). What is the ploidy
leonid [27]

Answer:

45 chromosomes (2n1 + n2)

Explanation:

The allotetraploid 2n1+2n2=60 has 60 chromosomes total, two sets of them of type 1 and two sets of chromosomes from the other type (2).

If the suspected type 1 parent is diploid with 30 chromosomes, then the allotetraploid has 30 type 1 chromosomes and 30 type 2 chromosomes.

<u>During meiosis, the germ cells reduce the total chromosome number by half.</u>

  • The gametes produced by the allotetraploid will have 15 type 1 chromosomes and 15 type 2 chromosomes.
  • The gametes produced by the suspected parent will have 15 type 1 chromosomes.

When these gametes combine during the backcross, the F1 zygote will have a diploid number of 30 type 1 chromosomes (15 coming from the allotetraploid and 15 coming from the suspected parent) and 15 type 2 chromosomes (which will be haploid because they all came from the allotetraploid).
