If a Cod Fish Parent has 82 Chromosomes in its Body Cells, how many

Chemistry
1 answer:
MakcuM [25]3 years ago
7 0

Answer:

41 chromosomes each

Explanation:

Meiosis is the means by which sexually-reproducing organisms produce gametes /sex cells used during reproduction. Meiosis is a kind of cell division that results in daughter cells (gametes) with a reduced number of chromosomes (by half). This means that meiosis reduces the chromosomal number of parents cell in the gametes.

Based on this, if a cod fish that possesses 82 chromosomes in Its somatic or body cells undergo meiotic division in order to produce gametes. The chromosome number of the sex cells will be reduced by half i.e. from 82 chromosomes (diploid, 2n) to 41 chromosomes (haploid, n)

If you had 6 moles of CaCl2 and 5 moles of Na3PO4, which of these would be the limiting and excess reactant
faltersainse [42]

Answer:

Na3PO4 is excess reactant, CaCl2 is limiting reactant.

Explanation:

                                      3CaCl2 + 2Na3PO4 ---> Ca3(PO4)2 + 6NaCl

from reaction :              3 mol        2 mol

given:                            6 mol         5 mol (X)

X = (6*2)/3 = 4 mol Na3PO4

For 6 mol CaCl2 we need 4 mol Na3PO4, but  we have 5 mol Na3PO4,

Na3PO4 is excess reactant, so CaCl2 is limiting reactant.

The acid dissociation constant ka for an unknown acid ha is 4.57 x 10^-3 what is the base dissociation constant kb for th econju
SashulF [63]

Answer:

2.19 x 10^-12.

Explanation:-

The relation between Ka and Kb for an acid and it's conjugate base is

Ka x Kb = Kw where Kw = ionic product of water.

So Kb = 10^-14 / (4.57 x 10 ^ -3)

= 2.19 x 10^-12
