Answer:
A. Water enters a plant by passing through the root cell membranes.
Explanation:
Osmosis is a kind of passive transport i.e. no energy input is required by the cell, that involves the movement of water across a semi-permeable membrane from a region of low solute concentration/high solvent concentration to a region of high solute concentration/low solvent concentration. The movement is usually facilitated by a difference in concentration gradient between the cell's membrane and the extracellular solution.
In this question, water from the soil enters into the root's cell via its cell membrane, which acts as the semi-permeable membrane. This movement must have occured because the solute concentration in the root's cell is higher than that of the soil, forming an osmotic gradient.
The answer is T A A C G T.
Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced. Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C).

Answer:
Prokaryotic and Anaerobic
Explanation:
Prokaryotic and Anaerobic organisms developed first.
Answer:
true
Explanation:
this is true. because some freshwater evosystems are terrestrial
Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
