Calcium oxide:
II II
Ca O ---> CaO
water ---> H₂O
CaO + H₂O -----> Ca(OH)₂
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
Answer:
If the sun was farther away from Earth
Explanation:
Answer:
The amount of organic matter in mineral (sand, loam or clay) soils ranges from very low being 1% by weight, to average being 2 to 4%, and high being greater than 5%. There are also “muck” or organic or peat based soils that are 30 to 40% organic matter. The general consensus is the more soil organic matter the better. approximately 45%
Soil Composition
The basic components of soil are minerals, organic matter, water and air. The typical soil consists of approximately 45% mineral, 5% organic matter, 20-30% water, and 20-30% air. These percentages are only generalizations at best.
