Mars has a surface in which is covered with red iron oxide dust
The correct answer among the choices listed above is option D. The connection between the mother and the embryo that provides the embryo with oxygen and nutrients and waste disposal is the placenta. Hope this answers your question. God Bless.
It should be when A. late in the third trimester, specifically months 7 and 8. It can't be B or D because the baby is breathing and getting oxygen through the placenta. It's not C because the lungs will de fully developed by the time the baby is out. In the 3rd trimester "the lungs are still developing still shortly before birth, but rhythmic breathing movements begin before lungs are fully developed." Its in my notes. I hope this helps!
They both of cell membranes if I remember correctly.
This is an example of founder effect and genetic drift. The right answer is A and C only
Explanation:
Genetic drift is a mechanism in the process of evolution in which the sampling error ( change in allele frequencies of population occur).
Here Genetic drift will lead to founder effect as colonization of species has taken place.
When a small population forms colones and does not contain the genetic diversity present in parental population. The movement from larger population to smaller population and having different gene frequencies is called Founder effect. The change in the alleles would lead to generation of same alleles and hence they will experience drift over a large period of time.
