Answer:
It is important that cell growth in a multi-cellular organism be regulated carefully so as to maintain the integrity of the cell cycle
Explanation: Each cell in a multi-cellular organism has it cycle which consist of the inter-phase and the m-phase (active division). Cell growth takes place in the G1 phase of the inter-phase and this ensures that deoxy ribonucleic acid is synthesized in the S-phase in preparation for division.
Hence, adequate cell volume is a key event in order for division to take place. If cell growth is not regulated, it might result in a cell exiting the cell cycle into the resting phase in case of slow growth or result in over-division of a cell in case of over-stimulated growth. The latter is often the case in the development of cancerous cells.
Answer:
blood flow
Explanation:
An aqueous stagnant layer that overlies the apical membrane and the subepithelial blood flow are potential barriers to the absorption of drugs that readily penetrate the absorbing cell of the epithelium. The apical, basal, and basement membranes are potential barriers to the absorption of less permeable drugs.
D. A perfect flower is basically a male flower and a female flower because it has both male and female parts

Answer:
Chlorophyll absorbs the light needed for photosynthesis.
Explanation:
Photosynthesis is the process where green plants manufacture their food. During photosynthesis, carbon dioxide combines with water in the presence of light energy from the sun to produce glucose and oxygen as a byproduct.
From the statements listed, chlorophyll does not combine with water. Chlorophyll is a pigment in plant that simply absorbs light energy from the sun which is necessary for the process of photosynthesis. This makes photosynthesis a simple process in which light energy from the sun is transformed to chemical energy.
