Answer:
That's because warmer air incubates viruses faster in mosquitoes, which gives them more time to spread them. Combine that with the fact that warmer temperatures make them hungrier for blood meals, and you've got a recipe for a potential outbreak.
The study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin and distribution is called biology.
Answer:
organisms that have a nucleus
Explanation:
eukaryotes have nucleus.
Answer:
The duplication of a cluster of four Hox genes is equally likely as the duplication of a single Hox gene.
Explanation:
This comes from the definition of the parsimony principle, which is the action of choosing the simplest scientific explanation fitting the given evidence, meaning that all other elements are equal when evaluating the hypothesis. In biology the best hypothesis is the one that requires the fewest evolutionary changes.
Since three independent duplications of an individual Hox gene is in evolutionary terms, more complex than a single duplication or a cluster, then that hypothesis would be the most parsimonious.
Answer:
Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).
Explanation:
The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.
