Biodiversity is essential in medicine as most active chemicals used to make medicines are derived from plants or other organisms. Climate change today threatens species that are vital to medicine. An example would be coral reefs. Studies have been done on reefs that look at fighting cancers, HIV and other ailments. One of the richest zones of biodiversity is the tropics and this region is under threat from global warming and deforestation. It is important to preserve these species for use in future medicinal research. <span />

Your eyes don’t change color, they only reflect the colours around them in particular if they are light coloured eyes. My eyes are blue-grey with a green heterachromia. They are very sensitive to light and dust so they get red easily which makes the eye color appear a brighter blue.

The answer would be D.
In binary fission the singular DNA strand is broken down and replicated, whereas in mitosis multiple different types of chromosomes are replicated.
There are a few key methods to calculate the rate of photosynthesis. These include:
1) Measuring the uptake of CO2
2) Measuring the production of O2
3) Measuring the production of carbohydrates
4) Measuring the increase in dry mass
As the equation for respiration is almost the reverse of the one for photosynthesis, you will need to think whether these methods measure photosynthesis alone or whether they are measuring the balance between photosynthesis and respiration.
