Block mountains form along fault blocks. Tension in a fault block can cause horsts in the fault block to tip. The horst edges point upward, forming a range of exposed mountains.
Explanation:
We are dependent on photosynthesis because photosynthesis is an essential process in our natural environment that helps to sustain plant life, produce oxygen, reduce Co2, and promotes human and animal well-being.
Answer:
1. Iterative homology: e.g. antenna and leg of fiddler crab
2. Ontogenetic homology: e.g. radular teeth of veliger, feathers of chicken and hen
3. Di-polymorphic homology: e.g. white and brown feathers of hen races, chelae of male and female of fiddler crabs
4. Supraspecific: e.g. chelae of fiddler crab, chelae of lobster, feathers of hen and pheasant
Explanation:
Crossing over is important because it creates genetic variability.
<h3>What is crossing over?</h3>
It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.
Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.
Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.
