g DNA polymerase is used in PCR to cut DNA sequences into fragments that can then be inserted into vectors. true of false

False

Explanation:

The answer is False.

The DNA polymerase is an enzyme that adds nucleotide bases to the growing chain during the elongation process of DNA replication. It is also utilized in the Polymerase Chain Reaction process to synthesize and amplify the DNA of interest.

Polymerase Chain Reaction is primarily carried out to amplify a DNA of interest in order to be able to study it in careful detail. Cutting of DNA into fragments is carried out by restriction enzyme and this is only done during genetic engineering when a foreign gene is to be inserted into a genome.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.
