B
The answer is B because,If the the water concentration of sugar particles is greater than that of the medium(the medium is a hypertonic solution) the number of sugar molecules diffusing out will be more than than that entering and the cell will shrink and shrived due to osmosis
Answer:
Evolution
Explanation:
Whenever a species changes over a period of time, it's called Evolution, which is (normally) driven by Natural Selection.
The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.
On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.
The given cross represent the cross between purple (PP) and white (pp) pure breeds.
When meiotic cell division occurs, a diploid parent cell experiences cell division to produce four haploid cells. Thus, if three parent cells undertake meiosis, <u>twelve haploid cells</u> will be created.
Aquired traits arent passed onto offspring and natural selection takes place over a long period of time over many generations so only genetic traits can change over a period of time whereas aquired traits, eg a lost limb, are random and one off
