As subduction occurs, the oceanic crust moves from the _____ toward a ____.

Biology
1 answer:
kirill [66]3 years ago
7 0

Answer: Mid Oceanic Ridge (MOR) to Deep-Oceanic trench

Explanation: As the plate tectonic theory is a continuous process, so at some places, divergent plate movement takes place whereas at other places, convergent plate movement takes place. So from that context we can conclude that

  • initially two plates moves apart from each other,
  • and this plates then collides with the other nearby plates, thereby the heavier one gets subducted beneath the other, forming a deep sea trench.

A rare genetic disease which is due to a recessive allele (a) and that is lethal when homozygous, occurs within a specific popul
valkas [14]

Answer:

40 individuals

Explanation:

The homozygous recessive percentage is equal to q2.

Recessive genotype frequency, q 2 is 1/1000000  = 0.000001  

therefore, q = \sqrt{q2}  = \sqrt{0.000001 }  = 0.001 =  allele "a" frequency  

and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999  

thus, the frequency of allele a = q = 0.001  and the frequency of allele A = p = 0.999

Carriers are heterozygous and are equal to 2pq.  

So, 2pq = 2  x 0.999 x 0.001 x  20,000 = 39.96 (round of to 40)

Hence, 40 individuals will be expected to carry the recessive allele.
