The process for connecting two monomers together is called dehydration synthesis. Dehydration means
“removal of water” and synthesis means “to join together”. So in this
process, two monomers are covalently bonded by the removal of a
water molecule. Each organic monomer has a hydroxyl group on
one side and a hydrogen on the other. When two monomers line
up side by side, they will have these two functional groups facing one
another. The H and the OH will break off of their respective
monomers and bond forming a water molecule. This is the dehydration
part of the process. Each monomer now has a carbon atom that needs
to covalently bond with something, so they bind to each other forming
a polymer. That is the synthesis part of the process.
Answer: bisphosphate carboxylase oxygenase
Explanation: Ribulose-1,5-bisphosphate carboxylase oxygenase is a copper-containing enzyme that is involved in the first step of carbon fixation of the Calvin cycle. It is the most abundant protein on the earth and is the central enzyme of photosynthesis.
If the blood vessels are replaced with collagen connective tissue, they will no longer be elastic and become hard, so the vessels will lose their ability to stretch. This hampers performance.
What is the difference between connective tissue, collagen fibers, and elastic fibers?
- Collagen fibers are the strongest and most abundant of all connective tissue fibers. These are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.
- Elastic fibers are long and thin fibers that form a branching network in the extracellular matrix. They help the connective tissue to stretch and recoil.

Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.
Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;
Reduces Water Shortages
In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.
Replenishes Groundwater
Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.
Reduces soil erosion
Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.
The DNA is a double-stranded molecule that has a long chain of nucleotides. The RNA is a single-stranded molecule which has a shorter chain of nucleotides. DNA replicates on its own, it is self-replicating. RNA does not replicate on its own.
