Answer:Condensing the DNA into tightly packed chromosomes makes the process of chromosome alignment
Explanation:
Throughout most of the life of a cell, the DNA is only loosely wrapped around the histones and is not in the condensed chromosomal form. ... Condensing the DNA into tightly packed chromosomes makes the process of chromosome alignment and separation during mitosis more efficient
Answer:
98 g/mol
Explanation:
atomic mass for hydrogen=1
atomic mass for sulphur=32
atomic mass for oxygen=16
atomic mass for sulphuric acid=2H + S + 4O
=2x1 + 32 + 4x16
2+32+64=34+64
=98g/mol
When a molecule loses or gains an electron it becomes an ion.
"If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion."
Answer:
c. −1.22 × 10^4 K
Explanation:
Generally, the slope of an Arrhenius plot can be determined either from the graph of In k against 1/T or the available experimental data of the rate constant (k) and the absolute temperature. Mathematically,
Where:
L/(mol.s)
L/(mol.s)
K
K
slope = (ln 2.9*10^-1 - ln 6.6*10^-4)/(1/500 - 1/400)
slope = (-1.238+7.323)/(0.002-0.0025)
slope = 6.085/-0.0005 = -1.22*10^4 K
