D. The basic structure is the carbon atom
First off this is more of an option question.
However personally I would go with:
Descriptive Quantitative (and or) Meta-analysis
Answer:
AA , Aa , Aa and aa
Explanation:
AA X aa gives 4 Aa (F1)
When F1 is crossed Aa x Aa gives AA ,
2 Aa and aa (F2 generation)
<u>Answer:</u>
Blastocyst is a structure that subsequently forms the embryo during the process of fertilization.
<u>Explanation:</u>
- In the "innermost layer of the uterine wall" there is endometrium layer, this is where the uterus does the embryo implant.
- The blastocyst stage is the period of embedding the "lining of the uterus".
- But the fertilization of egg is done in the "Fallopian tube" and is later implanted in the uterus.
- Hence blastocyst is the lining structure of the uterus as the implantation of embryo occurs.
Answer:
Option C
Explanation:
Given ,
A1 allele is carried by
% people
Let us assume A1 s dominant genotype
This means 
Thus, frequency of allele in the given population is 
It is also given that the population is in Hardy-Weinberg equilibrium thus

Frequency of fruit fly with genotype A2A2 will be

As per Hardy-Weinberg's second equation of equilibrium

Hence, option C is correct
