Answer:
Dehydration reaction includes removal of water molecule from compounds to facilitate formation of bonds between them while hydrolysis reactions break the compounds by breaking the bonds.
Dehydration reactions form the complex macromolecules while hydrolysis reactions break them down into the simpler elements.
Explanation:
During dehydration reactions, removal of a water molecule from two compounds leads to the formation of a covalent bond between them. These reactions are mainly part of anabolic pathways. Two amino acids are joined together by peptide bond and a water molecule is released during the reaction.
Hydrolysis reactions are the opposite of dehydration reactions and are involved in catabolic pathways of macromolecules. The peptide bonds between amino acids are broken down by hydrolysis.
Answer:
246
Explanation:
Increased amount / current population = 972
Amount released = 108
time(t) = 2years
Using the exponential growth function :
f(t) = A*g^t
Where g = growth rate
To obtain the growth rate = g
972 = 108 * g^2
g^2 = 972 / 108
g^2 = 9
g = 3
To determine population after 9 months :
9 months to years = (9/12) = 0.75
t = 0.75
f(0.75) = 108*(3^0.75)
f(0.75) = 108 * 2.2795070
f(0.75) = 246.18676
= 246
A method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.
<h3>What do you mean by mRNA?</h3>
mRNA may be defined as a molecule in cells that holds codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm.
The mRNA can be easily isolated from other types of RNA by the most reliable and convincing method of oligo (dT) chromatography which is the magnetic separation method that bounds oligo (dT) molecules on the surface of paramagnetic beads.
Therefore, a method by which you could separate mRNA from the other types of RNA in a eukaryotic cell is oligo (dT) chromatography.

Answer:
D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere
Explanation:
Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.
CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.
Answer:
Sperm-egg interaction
Explanation:
The formation of fertilization envelope is well-studied on the model system- sea urchin. It has been shown that, the fertilization envelope is formed after the initial sperm-egg interaction from the egg surface vitelline envelope and the paracrystalline protein fraction which is derived from cortical granules. Secretion from cortical granules, prevents polyspermy.
