Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.
Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
Natural selection affects or changes a population and not only an individual organism because as there are somethings to be changed in a certain organism to adapt to the changes in the environment, all organisms in a certain species will be able to adapt and the changes therefore is collective.
The enzyme is lipoxygenase.
Lipoxygenase is a variety of enzymes that can cause oxidation of fatty acids. There are several varieties of lipoxygenases, some of which are present in plants. They are involved in the formation of white blood cells that are involved in some severe allergic reactions (anaphylaxis). <em>It is based on this knowledge that antiallergic drugs have been developed to inhibit the activity of lipoxygenase, including reducing inflammatory reactions.</em>
Leukotrien are named thus because they were discovered in leucocytes and that they are unsaturated lipids with 3 conjugated double bonds (trienes) and 20 carbon atoms
The answer is a. builds underground burrows, hunts at night, obtains waterfrom its food.
Desert climate is specific for high temperature during the day, very cold nights and rare rain. So, animals must adapt to this conditions. The kangaroo rat builds underground burrows where it spends the most of its day. When the temperature falls down at evening it goes out to hunt. Usually, the kangaroo rat eats seeds which are rich in water.
