Slate, Skarn, Marble, and Quartzite are Metamorphic Rocks.
BUT SKARN is the type of rock that does not belong in the same category as the others.
Slate metamorphosed from mudstone. Marble metamorphosed from limestone. Quartzite metamorphosed from sandstone. All these rocks retain their solid forms.
Skarn<span> is a metasomatic rock composed of calc-silicate minerals.
Skarn is formed at the contact zone between carbonate rocks and silicic
magma. Skarn is often rich in hydrothermal ore minerals.</span> Skarn as a metamorphic rock is dissolved under metasomatic process and hardens back into a rock.
The reason they have to be so accurate and precise is because, let's say you were doing a lab or something that was involving chemicals. If you had to put a certain amount of chemicals in your experiment, but when you were doing to the math, you messed up and didn't go back and even bother to fix it, that is a really BIG issue. Because something will probably happen to your chemicals because you might have added to much of something into it. So that's why you always have to be so precise and accurate!
Answer:
B
Explanation:
The 3'-end of the reverse primer (3'-TTGGCCAATGG---5') is complementary to the forward primer (5'---AACCGGTTACC-3') and thus reduces the ability of the primers to bind to the targeted DNA sequence. There is possibility of hairpin loop formation or primer dimmers formation
Answer:
Ecosystem distribution
Explanation:
<u>The placement of biomes throughout the earth as a result of climatic factors such as temperature and precipitation is referred to as ecosystem distribution.</u>
Biomes generally represents a community of living organisms that are able to tolerate the climate of a place based on shared attributes. For example, all plants in the desert biomes are able to withstand low water.
An ecosystem refers a collection of different communities of organisms that are interacting with one another and their physical environment as a form of system.
Climatic factors such as temperature and precipitation delimits species distribution in an environment. Communities that are able to tolerate similar climatic conditions are placed in the same ecosystem. Hence, we have the <em>forest ecosystem, desert ecosystem, marine ecosystem, freshwater ecosystem, etc.</em>
