Answer:
At the beginning of the follicular phase, the lining of the uterus (endometrium) is thick with fluids and nutrients designed to nourish an embryo. If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
Explanation:
Here, Cross: = WW × ww
Here, W(white) is dominant over w(yellow).
Offspring: Ww , Ww, Ww, Ww
1) Genotypes: Ww , Ww, Ww, Ww
2) Phenotypes: They all will be "White"
3) Genotypic ratio = WW:Ww:ww = 0 : 1 : 0
4) Phenotypic ratio = White : Yellow = 1 : 0
Hope this helps!
Answer:
the cell membrane (or plasma membrane)
Answer:
Newer layers of earth form <u>on</u><u> </u><u>top</u> of older layers, so as we dig, we can see further back in time. Comparing the fossils between the layers can offer evidence of change.
<u>Phyletic</u><u> </u><u>gradualism</u> - slow, but constant gradual change; supported by transitional species in the fossil record
<u>Punctuated</u><u> </u><u>equilibrium</u>- long periods of no change followed by short periods of rapid change. Can also be supported by the fossil record when no transitional species are found.
