Answer:
1/3
Explanation:
Let's assume that the allele "P" imparts purple phenotype to flowers while the allele "p" gives white phenotype. The self-fertilization of purple-flowered parent plants gave purple and white progeny in almost 3:1 (28:10) ratio. This means that the parent plants were heterozygous and the genotype of each was "Pp".
A cross between Pp and Pp produces progeny in the following genotype ratio=
1/4 PP: 1/2 Pp: 1/2 pp
So, out of total 3/4 purple progeny, 1/3 is homozygous for the purple allele (PP) while the rest 2/3 is heterozygous dominant.
I have three: glucose, fructose, galactose
I'd say D cause ice is kinda more likely to do the job
Answer:
Depolarization
Explanation:
Depolarization is a change in cell's membrane potential such that the inside of the membrane is made less negative relative to the outside by moving the voltage in the direction of zero Voltage.
Action potentials occur whenever a depolarization increases the membrane voltage to a threshold, which usually has a membrane potential value of -55mV.
