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)
Answer: the following are essential factors to be considered when choosing a solvent for crystallization
1. The crystallization solvent should not dissolve the substance to be purified at room temperature, but it should dissolve it well at the solvent’s boiling point
2. The solvent should dissolve soluble impurities well at room temperature.
3. The solvent should not dissolve insoluble impurities even at the solvent’s boiling
point.
4. The solvent must not react with the substance to be purified .
Answer:
final pressure ( P2) = 467.37 mm Hg
Explanation:
ideal gas:
∴ P1 = 570 mm Hg * ( atm / 760 mm Hg ) = 0.75 atm
∴ T1 = 25 ° C = 298 K
∴ V1 = 1.250 L
∴ R = 0.082 atm L / K mol
⇒ n = P1*V1 / R*T1
⇒ n = (( 0.75 ) * ( 1.25 )) / (( 0.082 ) * ( 298 ))
⇒ n = 0.038 mol gas
∴ T2 = 175 °C ( 448 K )
∴ V2 = 2.270 L
⇒ P2 = nRT2 / V2
⇒ P2 = (( 0.038 ) * ( 0.082 ) * ( 448 )) / 2.270
⇒ P2 = 0.615 atm * ( 760 mm Hg / atm ) = 467.37 mm Hg
Answer:
Cells are the basic structural unit of all living organisms.
Explanation:
Hope this helps, but i'm unsure if it would be multiple choice or not.
