Answer:
4
Explanation:
According to Mendel's law of purity of gametes, each gamete contains single allele for a gene. The alleles of a gene segregate during gamete formation and each gamete has one allele for a gene irrespective of the total number of alleles for a gene.
If the gene for skin color in a fish species has four alleles, an individuals fish would have only two alleles which in turn would segregate during gamete formation.
Since there are four different alleles of the gene (let's assume a,b,c, and d), total possible gametes produced by this organism will be = 4. A gamete can have one of the total 4 alleles making total 4 types of the gametes each with a or b or c or d allele.
Answer:
They do not belong to the same population
Explanation:
These two similar birds do not belong to the same population because a population is made up of groups of similar organisms of the same species that occupy the same geographical region including the capability to interbreed. This two birds despite the similar markings, they do not have the capability to interbreed thus they are not of the same population.
Answer:
a. Extremophile
Explanation:
These kind of living things, can support extreme changes of conditions, like in this example, they cam growth in a perfect 32 ºC, but they can still reproduce and live in a very cold temperature.
I will not select the psychrophile because, even they are extremophiles, actually, they prefer the cold weather, that mean that it will not have an optimum growth at a temperature of 32 ºC.
Answer:
6.75l l/min
Explanation:
Streptomycin is extracted from the fermentation broth using an organic solvent in a counter current staged extraction unit.
for 5 stage counter current staged extraction unit for streptomycin
X5 = 0.2g/l
X0 = 10.0g/l
X5/X0 = 0.02
given
Xn/X0, E, and
n = 5
A estimate of E can be evaluated directly;
E = 1.8
= LKd/H
by substituting the given values; Kd = 40, H= 150l/min
then we have,
L;L = 1.8(150)/40
= 6.75l l/min
