scientists have used mtDNA as a molecular clock to trace human evolution and early migration routes explain why mtDNA would be more useful in this research than rRNA

Answers

An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene. This is how mitochondrial DNA (mtDNA) typing is used in forensic science.

Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.

If you wanted to increase the rate of photosynthesis in a plant, you would develop a plant with which of the following characteristics? a strong, thick stalk bright flowers to attract bees many, broad leaves short, narrow leaves

Answers

In order to increase the rate of photosynthesis in a plant, a plant should be developed with many broad leaves. The broad leaves will have increased surface area and more chlorophyll. The increased number of the leaves in the plant will also contribute to the overall increased rate of the photosynthesis.

A strong and thick stalk will support the plant but will have no effect on the rate of photosynthesis. Narrow leaves will decrease the photosynthesis rate. Bright flowers will aid in pollination via the honeybees but not increase the photosynthesis rate.

Hence, the correct answer is 'many broad leaves'.

Many broad leaves, which allows gathering more light.
