In the population with a large number of individuals, the mutation would only have a small impact, while a population with only 18 individuals would result in a very large i off as the mutation would be in a greater percentage of the population.
There should be options for this question. I manged to find them elsewhere. They are:
A) the period during which tremendous growth occurs and the organs continue to develop and become functional
B) the period during which the umbilical cord develops
C) the period during which the major organs and structures of the organism first develop
D) the period during which the zygote moves down to the uterus and begins to implant in the lining
The correct answer is C. The embryonic period is the period during which the major organs and structures of the organism first develop. The embryonic period lasts from implantation of the egg in the uterus until about 8 weeks from the time of conception. It is the second major stage of prenatal development, prior to embryonic is the germinal stage and lastly is the fetal stage.
Test One: All short fur
Phenotype ratio: 4:0
Test Two: three short fur and one long fur
Phenotype ratio: 3:1
Test Three: all long fur
Phenotype ratio: 4:0
Genotypes for fur length dominant
G: FF, and Ff (These are the genotypes for short fur, short fur is a dominant gene.
P: Short fur is dominant
Genotypes and phenotypes for fur length recessive
G: ff
P: Long fur is recessive
If you have a hamster with short fur, the possible genotypes the hamster could have is FF, and Ff
If you have a hamster with long fur, the possible genotype is ff.
Answer:
The ability to maintain a reasonably steady internal state that persists despite changes in the external environment is known as homeostasis. To utilize energy and eventually survive, all living species, from plants to puppies to humans, must manage their interior environment.
The carry the deoxygenated blood from the heart to the lungs and Pulmonary veins do the opposite!
