The answer is D. NADH to NAD+
When no oxygen is present, anaerobic respiration occurs.It is the only way to produce ATP in this condition.NAD+ is necessary because it is converted into NADH and at the same time ADP is converted to ATP in the reaction of pyruvate synthesis from glucose.Therefore, NADH must be converted to NAD+ in order to have NAD+ always present in the cell.
Answer: The statement is correct in scientific sense.
Explanation:
Adaptation refers to the traits or characteristics posses by living organisms which enable the organisms to be better fitted to survive, and reproduce in it's environment.
Adaptation is an evolutionary process I.e. features are evolved by the organisms to be better suited in it's environment.
From the statement, an individual crab develop characteristics that enable it to change its position which enable it upright stance to further adapt to life in land.
Cytoplasm and cytoskeleton both provide support for a cell and hold everything together. Transport proteins in the cell membrane allow helpful molecules such as glucose to enter the cell. They also act as enzymes that speed up processes and indicators that warn the cell if danger is nearby.
My answer would be trees and shrubs
Answer:
Algal bloom. Bright green blooms may also occur. These are a result of blue-green algae, which are bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.
