The angle of Earth's tilt has changed throughout Earth's history and is still changing today. If Earth's tilt were to decrease
olganol [36]

Answer:

The world climate would drastically change.

Explanation:

  • First off, both poles would have rapid expansion, with the freezing of more water near the poles.
  • Many species of trees and plants would die out in certain areas, since they tend to be in their ideal locations, so the change in climate will make the northern parts of many habitats destroyed.
  • Deserts would expand and the average temperature would rise.
  • Also, many animals would also die out, because of the change in their environments.
  • Conifers would shift southward, causing many forests / parts of forests to turn into wastelands, causing the earth's oxygen production to decrease.

There are two alleles, B and b, at a gene locus in a population at Hardy-Weinberg equilibrium. The relative frequency of the dom
viva [34]

Answer:

210

Explanation:

Frequency of dominant allele is represented by "p"

and frequency of recessive allele is represented by "q"

Given

p = 0.7

Thus,

q = 1-p\\q = 1 - 0.7 \\q = 0.3\\

As per Hardy Weinberg's second equation of equilibrium -

p^2 + q^ 2 + 2pq = 1\\

Substituting the given values in above equation, we get -

0.7^ 2+ 0.3^2 + 2pq = 1\\2pq = 1- 0.49-0.09\\2pq = 0.42

So the total number of heterozygous individual is equal to

0.42 * 500\\= 210

Which of the following structures is not found in bryophytes?
WINSTONCH [101]

Answer: The answer is ROOT

Explanation: Briophytas belong to the plantae kingdom, therefore they have a cell wall in their cells, and chloroplasts. They have sporangia (structure where the spores are produced and stored)  but they do not possess proper roots. Instead they have a structure called "rhizoid" whose function is the fixation to the substrate.
