"The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top."
Oldest to youngest: Layer B, Layer C, Layer A
The oldest is always at the bottom, the youngest layer is at the top
The Hardy-Weinberg principle is used to characterize the distribution of the different genotype frequencies in a population which are not evolving. In the Hardy-Weinberg equation,
the frequency of the homozygous dominant genotype is denoted by 
;
the frequency of the homozygous recessive genotype is denoted by 
;
the frequency of the heterozygous genotype is denoted by 2pq;
the frequency of the recessive allele is denoted by q;
the frequency of the dominant allele is denoted by p.

Physical exercise preserves bone mass. Measurements of bone biomarkers may reflect the events in bone during exercise. Fifteen healthy, well-trained individuals (7 men and 8 women) performed a running test for 21 min until exhaustion. Venous blood samples were drawn before and 30 min after the exercise to measure the levels of osteocalcin, the carboxyterminal propeptide of type I procollagen (PICP) and the carboxyterminal cross-linked telopeptide of type I collagen (ICTP). After exercise, the women had a marked increase in serum osteocalcin concentrations (from 7.5±5.0 μg/1 to 11.5±3.0 μg/1), whereas the level was unaffected in the men (from 14.5±3.0 μg/1 to 13.5±4.6 μg/l). In the men there was a marked increase in PICP (from 240±47 μg/1 to 268±56 μg/1) that was not seen in the women (from 244±70 μg/1 to 253±60 μg/1). In neither group did ICTP levels change. In conclusion, significant responses were seen in PICP and osteocalcin during exercise, indicating that such measurements may be valuable for the further delineation of the effects of physical activity on bone. Furthermore, the different responses in men and women point to interesting areas for future studies.
Answer:
Explanation:
Amount of water displaced by the sphere will be equal to the volume of complete sphere.
As the sphere completely sinks to the bottom of the cup.
We have been given;
Diameter of sphere (d) = 4.6 cm
So,
Volume of sphere (V):
By substituting value of r we get:
1 cm³ = 1 mL
V = 51 mL
So,
Water displaced by the sphere = 51 mL
