Answer:
using only two types of seeds, both from the same source, repeating the experiment indoors under growth lights, and measuring plant height the same way and at the same time for both groups
Explanation:
Layer 2 and layer 9 are the same relative age.
Explanation:
The statement that best describes the rock layers is that Layer 2 and layer 9 are the same relative age..
The relative age is used in placing sedimentary rocks in order of their occurrence.
To do this, we apply the sedimentary laws.
The ones applicable here are:
- Principle of superposition states that in an undisturbed sequence, the oldest layer is at the base and youngest on top.
- Principle of cross cutting states that a fault and intrusion are younger than the rocks they cut through.
- Principle of fossil and fauna succession states that fossils and fauna succeed on another in a determinable form.
We see that layers 2 and 9 have the same fossil and are the same lithological units.

Answer:
dCDP
Explanation:
The nucleotide has hydrogen at it second carbon which means that it has deoxy pentose sugar which is written in small d as prefix.
The nitrogenous base is cytosine and it contains 2 phosphate groups which are attached to the 5 carbon of the pentose sugar means it is cytosine diphosphate.
<u>So, the abbrevation of the molecule is : dCDP</u>
Answer:
Helium and also nitrogen
Explanation:
Helium, as well as nitrogen, can be used for storage of a fresh sample of an oil for a long time because they prevent the oil from rancidity. The contact of air and oil is prevented by using nitrogen or helium as blanketing gas.
Answer: at dynamic equilibrium, the rates of forward and reverse reactions are equal.
