While preparing to build a hydroelectric dam, the safety for various potential hazards must be given attention. Some of these include special attention towards the channels leading to dangerous areas or spillways, attention towards the effectiveness of the barriers, areas where higher currents exist, attention must also be given towards environmental aspects such as damming the rivers impacts wild and aquatic life, reduction of dissolved oxygen harming the fishes, and also while building the dam the communities living around should be taken into consideration that there is no potential hazard to them.
Answer: Ultimately, a beach erodes because the supply of sand to the beach can not keep up with the loss of sand to the sea. Most sand is transported from inland via rivers and streams. The damming of most waterways in the US has thus prevented a major supply of sand from getting to our beaches.
Answer:
The Hardy Weinberg symbol for the dominant allele is 'p' in his equilibrium equation.
Explanation:
- The equation given by Hardy: "
" is known as "Hardy-Weinberg equilibrium equation". - The frequency of dominant allele and recessive allele for a trait is represented by 'p' and 'q' respectively.
- 2pq in the equation is the frequency for heterozygous genotype.
- Conditions that must be considered for the Hardy-Weinberg equilibrium equation to satisfy are: no mutations
, no flow of gene, large population size, no selective forces
, no non-random mating.
D. The planet's orbital path will become smaller and its orbital period will increase.
The more gravity an object has, the more it will pull objects.
