Answer: Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
Answer:
p=0.9
Explanation:
The frequency of the different genotypes is as follows:
- AA = 0.81
- Aa = 0.18
- aa = 0.01
There are 2 alleles for this gene, the dominant allele <em>A</em> appears twice in the homozygous dominant genotype and once in the heterozygous.
Then, the frequency of the <em>A </em>allele, <em>p</em>, can be calculated as:
p= freq(AA) + freq(Aa)/2
p= 0.81 + 0.18/2
p=0.9
The valve that prevents black flow into the right atrium is the tricuspid
Weathering therefore occurs more slowly in granite than in layered sedimentary rocks. ... High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions!
