Explanation:
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
Answer:
D. The tubes allow water and nutrients to be transported throughout
the plant.
Explanation:
option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.
option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.
option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.
option B could possibly be right but option D is better suited.
The cell grows and develop and the chromosomes duplicate. Also, interphase is the phase where the cell spends most of its time in.
The aquifer which will be most effective in purifying polluted ground water is AN AQUIFER COMPOSED MAINLY OF SAND.
An aquifer refers to a zone of permeable rock strata which transmit ground water freely. An aquifer must be permeable and porous. Ground water can be extracted from an aquifer by using a water well.
Answer:
the process of DNA replication is called semi conservative because it results in two DNAs having a new strand and a old strand which is from the original DNA molecule
