Answer: The ocean is one of Earth's most valuable natural resources. It provides food in the form of fish and shellfish about 200 billion pounds are caught each year. It's used for transportation both travel and shipping. It provides a treasured source of recreation for humans
Explanation:
In my understanding,
Water can be considered as either weak acid/alkali or neutral, which means it does ionize by itself, but not too much.
So the lack of active ions in water allows other molecules to freely ionize and bond with each other.
Answer:
Gene- DNA - Chromosome- Nucleus
Explanation:
A gene is a sequence of nucleotide bases that specifies certain products; RNA or proteins. It is the segment of DNA that holds the information to build and maintain an organisms cell and also pass genetic traits to offsprings. Hence, it is the molecular unit of heredity in living organisms.
The DNA is a long double-helical structure that stores the genetic information in our cells. It consists of two long polynucleotide chains composed of the four nucleotides subunits (A,C,G,T).
In order for the long strand of DNA to fit into the cell's nucleus, it is coiled around certain proteins called HISTONES to form Chromatin, which undergoes further coiling and organization to to linear CHROMOSOMES.
The chromosomes are structured within the nucleus, that are made up of the cell's genetic material (DNA). In eukaryotic cells, the nucleus houses the cell's DNA and directs protein synthesis (expression of the information encoded by genes).
In contrast, when organizational entry is not handled well, the new employee can have less positive work attitudes, reduced commitment, higher absenteeism and turnover, and lowered performance.
Answer:
The correct answer is NADH and FADH2
Explanation:
Citric acid cycle or TCA cycle is the second stage of cellular respiration that occurs in mitocondrial matrix.
During TCA cycle various reducing equivalents are generated such as NADH and FADH2.They are the reduced form of NAD+ and FAD which act as co enzymes.
NADH and FADH2 of TCA cycle also act as electron carriers as they act donates electrons during Electron transport chain .
