Answer: DNA polymerase is an enzyme used in DNA replication.
Explanation: DNA replication is when DNA is copied from one parent (original) strand to two exact copies of daughter DNA strands so that genes are passed on from generation to generations. DNA polymerase is an enzyme that assist in DNA's replication. It catalyses the chemical reaction that results in duplicate DNA strands.

75% of the children will have the probability of being tasters. 25% will have the probability of being non- tasters.
Answer b)
There will be a 75% chance that their first child or their fourth child will be a taster.
The chances for every child will be the same because alleles assort independently during the time of gamete formation. Hence, the probability remains the same every time.
Answer c)
There will be a 25% chance for the first three offsprings to be non-tasters. 75% chances will be of them being tasters.
This is because the alleles assort independently each time during gamete formation. Hence, the chances will be the same every time.
Wetlands are often drained in many regions to facilitate human use of the land. This happens a lot within the Pairie Provinces of Canada, where wetlands are drained to make way for agriculture. Wetlands are also often drained so as to use the land for building houses. Humans have also altered the flow of rivers through constructing dams and over-abstracting water. In many regions, depressions that would have been flooded in the past to form wetlands are no longer saturated. Wetlands also act as a 'sink' for many pollutants, and much of the pollution released into upstream rivers by humans may settle into the relatively stagnant waters of wetlands, to be absorbed into the sediments, where often it acts as a chronic pollutant, negatively effecting the aquatic ecosystem and water quality downstream.
They occur when a blood vessel within the skull bursts and bleeds into and around the brain. The main cause of haemorrhagic stroke is high blood pressure, which can weaken the arteries in the brain and make them prone to split or rupture. Hope this helps :/ x
