Answer:
Apitite
Explanation: Apitite has a hardness of 5 it can scratch flouride but Quartz has a hardness of 7 meaning it can scratch Apitite
42% of rabbits in the population are heterozygous for the mutant Sp1 allele
Hardy-Weinberg equilibrium
- Assume that p is the frequency of the dominant allele
- p² is the frequency of the organisms with homozygous dominant genotype
- Assume that q is the frequency of the recessive allele
- q² is the frequency of the organisms with homozygous recessive genotype
- 2pq is the frequency of the organisms with heterozygous genotype
- p+q = 1
According to the question, 900 out of 10000 rabbits are homozygous recessive
- This implies that q² = 900/10000= 9/100= 0.09
- So, q = 0.3
- The frequency of the recessive allele is 0.3
- p = 1-q = 1-0.3= 0.7
For organisms with heterogenous genotype, their frequency is 2pq
2pq= 2 x 0.3 x 0.7 = 0.42
In terms of percentage, 0.42x 100% = 42%
Therefore, 42% of rabbits in the population are heterozygous for the mutant Sp1 allele.

Answer: I think it's D
Explanation: A mineral is a chemical substance made up of one or more chemicals having a definite crystal structure. Rocks do not have a definite chemical composition whereas minerals do. Sometimes a rock may contain organic remains in it.
Answer:
The correct option is: e. Both B and D
Explanation:
Type I alveolar cells are the thin squamous epithelial cells that lines the alveolar surface of the pulmonary alveoli.
These cells are involved in the gas exchange process. The thin lining of the type I alveolar cells, allows the rapid diffusion of gas and thus enabling the exchange of gases between the blood present in the capillaries and the air present in the pulmonary alveoli.
