Answer:

please give me brainlist and follow

Explanation:

This would cause mantle material to rise in its place, pushing up the crust and forming isolated mountain ranges and associated basins. This activity would cause minor earthquakes and maybe even additional pockets of volcanism.

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.

In a diploid species of plant, the genes for plant height and fruit shape are syntenic and separated by 18 m.u. Allele D produce
FinnZ [79.3K]

Answer:

C)Parental: 41% Dr, 41% dR; recombinant: 9% DR, 9% dr.

Explanation:

The notation Dr/dR for genotypes means that one homologous chromosome has the alleles Dr and the other homologous chromosome has the alleles dR.

The heterozygous plant  Dr/dR will produce 4 types of gametes: two identical to the chromosmes the individual has in its somatic cells (called parental), and two gametes which will be a mix of the alleles in the homologous chromosomes (called recombinant).

  • Dr: parental
  • dR: parental
  • DR: recombinant
  • dr: recombinant

To calculate the frequency of each type of gamete, we must use the formula:

Distance (map units) / 100 = frequency of recombination.

18 mu / 100 = 0.18.

The total frequency of recombination between the genes D and R is 0.18, but every time crossing over happens, two recombinant gametes are generated. Therefore, each recombinant gamete will have a frequency of 0.18/2=0.09 = 9%.

The frequency of parental gametes will be:

1 - frequency of recombinant gametes

1 - 0.18 = 0.82

But there are 2 parental gametes, so each of them will have a frequency of 0.82/2=0.41 = 41%.

What are the four states of matter and how might we see them in a crime scene
rodikova [14]
Hi! I'm assuming you know the four states of matter- solid, liquid, gas, and plasma.

Putting them into a crime scene, however, is tricky.

Depending on which type of crime scene it is, there will be different types of states of matter in each, or possibly multiple.

Liquid can be seen as blood if it was a murder. Solid can be seen in that same crime scene if the murderer by chance left his knife, gun, or solid device they used to commit the murder. In other cases, gas can be seen used to kill someone because of it's toxicity. Plasma is a hard one, though, but can be seen in blood as well, because our blood is made up of plasma and other materials.

Hoping I helped, and I'd love to receive brainliest answer! :)
