Answer: Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. These are the reservoirs, or sinks, through which carbon cycles. The ocean is a giant carbon sink that absorbs carbon.
Answer:
d. pxp +2pq
Explanation:
The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:
p² + 2pq + q² = 1
where, p = dominant allele
q = recessive allele
Here,
p² represents frequency of homozygous dominant genotype
2pq represents frequency of heterozygous genotype
q² represents frequency of homozygous recessive genotype
Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.
Answer:
The fusion of a egg and a sperm produces a zygote with 46 (2n) chromosome number.
There are three types of energy involved in a muscle's contraction. There is metabolism, catabolism, and anabolism. Metabolism is the events that are carried out in the human body to create energy and other things needed for activity. Catabolism is the process during the organic matter is broken down and the energy is released, it takes place during increased movement. Anabolism is the energy-consuming process that substances are created, it takes place when there is little movement. All three of these work to gather in muscle contraction.
