B. is a long crack, which releases lava, steam,  and gases

Explanation:

A fissure is a long crack which releases lava, steam and gases into the environment. Fissures are mostly associated with volcanic bodies.

A volcano is an igneous structure by which lava erupts on the earth surface.

  • most volcanoes have fissures through which they release materials into the environment.
  • these features are usually permeating cracks into the deeper magmatic body.
  • they often times acts as conduit for magma to reach the surface.
  • in a volcanic terrain, fissures can provide good clues to the occurrence of an eruption.

Let’s say A plant cell, normally diploid, completely screws up mitosis during metaphase and pulls full copies of all chromosomes
andrezito [222]

Answer:

4N

Explanation:

Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.

However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.

For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.

A population of 100 rats was analyzed for their genotype at the isocitrate dehydrogenase locus. There are two alleles (R and S)
goldfiish [28.3K]

Answer:

Yes, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg.

Explanation:

Here ,

f(A)= p=0.575

f(B)= q=0.425

As per the first principle of hardy Weinberg, the sum of all the alleles at the locus must be equal to 1.

Thus,

p+q=1\\0.575+0.425 = 1\\1=1\\

Also, as per the second equation of Hardy Weinberg's equation-

p^{2} + q^{2} +2pq =1

(0.575)^2+2(0.575)(0.425)+(0.425)^2=1\\0.3306+ 0.48875+ 0.180625=1\\1=1\\

Hence, this population lies in Hardy-Weinberg equilibrium as it follows both the principles of Hardy-Weinberg
