Answer:
Diploid cells abbreviated 2n and haploid cells abbreviated 1n because 'n' represents number of chromosome present in the cell. In haploid cells the number of chromosome is half in number while in diploid cells the number of chromosome is double so that's why haploid is abbreviated as 1n and diploid is abbreviated as 2n.
Diploid cells are present in body cells while haploid cells are found in sex cells.
Answer:
27
Explanation:
The number of protons in atom is the atomic number. For a neutral atom that has not lost or gained any electron, it is the same as the number of electrons.
The atomic number is used in perfect ordering of the periodic table and it is the basis of the periodic law.
Protons are positively charged subatomic particles that reside in the in the nucleus of an atom with the neutrons.
Answer:
a. movement can occur both upward and downward in the plant
Explanation:
The phloem loading causes the accumulation of sugars in the sieved elements generating a negative solute potential (quedas), with a drop in water potential (ψw), so water enters the sieved elements increasing the turgor pressure (ψp). With the discharge of phloem in the drain occurs lower concentration of sugars in the screened elements, increases the solute potential, becoming positive, thus the phloem water potential increases and thus the water leaves the conducting vessel. In the specific case of sugar movement in the phloem, it can be stated that this movement can occur both up and down in the plant.
Answer: Define Active transport
Explanation: The moving of molecules or ions across the cell membrane.
