The answers would be:
Rift Valley
Mid-Ocean Ridge
New oceanic crust
Here is why:
A divergent boundary is a boundary where two plates are<u> moving apart</u>. (You should remember this so you have an idea about what is formed)
A <u>rift valley</u> is formed when two continental plates (These are plates on land) <em>pull apart</em>, creating a rift in the middle. They are literally ripped apart.
The <u>mid-ocean ridge</u> was formed when oceanic plates moved apart. This also leads use to the new oceanic crust part.
Now when oceanic plates move apart, this leaves space for magma, from beneath the Earth's crust, to occupy and rise. When it goes out through the opening, it is cooled by the water on the surface, so it hardens and becomes <u>new oceanic crust</u>. This goes on and on and this is also how we can explain, seafloor spreading.
<em>*You might be wondering about the Deep Sea Trench. The deep see trench is created by subduction which occurs in convergent boundaries. The trench is the point where the other plate slides under the other. So this is NOT a divergent boundary formation. </em>
Specimen collection is the process of obtaining tissue or fluids for laboratory analysis or near-patient testing.
A specimen collection helps a scientist do an experiment by assembling a large number of samples for comparison. A poorly collected specimen may lead to failure in isolating the causative organism(s) and/or result in the recovery of contaminating organisms.
Once the wolves were gone, elk populations began to rise. Over the next few years conditions of Yellowstone National Park declined drastically. ... The elk were multiplying inside the park and deciduous, woody species such as aspen and cottonwood suffered from overgrazing.
Answer:
Option a. is correct
Explanation:
A mutation refers to a change in our DNA sequence which causes it to break down. It occurs due to the following reasons:
1. Due to mistakes when the DNA is copied
2. Due to environmental factors such as UV light, smoking.
3. Exposure to specific chemicals or radiation
The mechanism for reactive oxygen species to cause mutation is that bases are oxidized to a variety of different products which might pair with a different base than the original base would have.
