Answer:
B. Stress caused by forces that stretch an area of the crust made the rock to break
Explanation:
From the picture inserted to this problem, we see a unit that has been severely fractured.
Fracturing results from the brittle deformation of a rock under applied stress.
- Rock fracturing results in the formation of joints and faults.
- We can obviously see different sets of joint sets on the body of the rock in the picture attacked.
- Also, a prominent fault which resembles an extensional fault can also be seen.
- Therefore, the stress caused the stretch of the area which in turn makes the rock the rock to break.
Carbon is an essential to all living forms on earth, whether they need carbon intake to help produce food or release carbon for breathing. All plants and animal life need carbon, without it would be impossible for life on earth.
The asthenosphere and outer core would solidify.
deforestation- making room for new buildings by clearing trees and forests
pollution- from factories, litter, and bad hygiene
DNA replication occurs in the 5 prime (5') to 3 prime (3') direction.
I'm sure you've heard this many times. I tutor in genetics, and all of my students can rattle that off. Less understand what it means.
First, understanding what 5' and 3' mean is important. DNA is composed of a ribose sugar, a phosphate group, and a base (A,T,G,C). The sugar has a phosphate group attached to its fifth carbon, and a hydroxyl group on its 3rd carbon. Nucleotides (separate components of DNA) are linked by the phosphate group and the hydroxyl group. So, every nucleotide is linked at the phosphate group and the hydroxyl group besides two - the two nucleotides at either end of the strand of DNA. The one that leaves a phosphate group exposed is called the 5' end of DNA, and the one that leaves a hydroxyl group exposed is called the 3' end of DNA.
<span>A problem with many students just memorizing that replication occurs in the 5' to 3' direction is that there are two strands of DNA involved in replication. DNA polymerase (the major enzyme responsible for replication) reads the already existing strand of DNA in the 3' to 5' direction, and creates the new strand of DNA in the 5' to 3' direction (meaning that it adds nucleotides to the 3' end of the new strand).</span>
