Answer:
True
Explanation:
There are four biosafety levels according made to the pathogenicity of the organism. BSL-1 is used for those microbes which do not cause diseases in normal healthy person. BSL-2 is applicable for those microbes which posses moderate risk for humans and against whom therapeutic intervention is normally present in the market.
The worker who uses BSL-2 labs must be trained specifically for handling pathogenic microbes and they should be supervised by competent scientists so that any accident can be avoided. Therefore the statement is true.
Answer:
The kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.
Explanation:
We need to study two species of snakes, the Emerald Tree Bow and the Boa Constrictor, they belong to the same genus. However, the former is tree-dwelling and needs high humidity whereas the latter is terrestrial and requires a dry environment.
To explain this phenomenon we present a similar example: Imagine that your family has lived in the same house for many years. After that, imagine that your sister moves out of that house and into a house in a nearby neighborhood. She begins a new family there and, through the years, her family continues to grow and live in this new house. When your family separated, you became different groups of people from the same common ancestor. Eventually, you might even evolve enough to feel that there are more differences between you than similarities. When this happens in nature, it's called sympatric speciation. This process allows new species to evolve from a common ancestor, while the new and old species are still living in the same geographic region.
This example is almost the same as both snakes. Sympatric Evolution was responsible for this phenomenon.
Finally, we can conclude that the kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.
study them?
Answer: sterilize equipment and materials
Explanation:
Answer:
Phagocytosis.
Answer:
segregation
The law of segregation is the Mendel’s laws or principles explain that traits are passed from parents to offspring individually instead of as pairs, groups or sets.This is a law or principle which states that during the formation of gametes, two copies of each heredity factors separate out so that the new offspring can get one factor of both the parents. This law was the first law in this direction.

Answer:
Because the surface of a leave is nonpolar. I just did it!
Explanation:
The other answer is ridiculous! Please people don't answer (guess) if you haven't actually studied this before.
All the others ARE WRONG except for this one.
Just like when you step out of a swimming pool, why does the water roll off your body? Part of the answer is that your skin is made of cells that are covered in lipids. Lipids do not mix with water because water is made of polar molecules, and lipids are nonpolar molecules.
Ever heard the word hydrophobic? Nonpolar molecules are repelled by water and do not dissolve in water; are hydrophobic. A leaf is nonpolar! Water is polar! They don't dissolve...
This is correct and true! But before submitting an answer make sure the question is the same one. Stay Safe!
