Mutagens increase the likelihood of mutations in DNA.
A mutagen is a chemical or bodily agent able to induce adjustments in DNA referred to as mutations.
Mutations end result both from mistakes in DNA replication or from the dangerous outcomes of mutagens, along with chemical compounds and radiation, which react with DNA and trade the systems of person nucleotides. All cells possess DNA-restore enzymes that try and limit the range of mutations that arise
Examples of mutagens encompass tobacco merchandise, radioactive substances, x-rays, ultraviolet radiation, and an extensive sort of chemicals.

Answer:
3.6 (miles / hour) * 1609 (meters / mile) * 1 hour / 3600 second = 32.90 m/s
As you can see miles cancel out and hours cancel out - leaving meters / second
Explanation:
Answer:6 km/h
Explanation:
Given
Velocity of Sailboat is 
Velocity of ocean current is 
negative sign indicated it is opposite of Sailboat
Therefore, velocity of sailboat w.r.t ocean current is
This energy most directly results from the life activity of respiration.
The hummingbirds have very high energy expenditure (have the highest oxygen requirements of all vertebrae) with a fast heart rate, very fast wing beats and sustained hovering. So the hummingbird is nearly always on the edge of starvation, needing to take in more nectar than its body weight each day.
The respiratory system of these birds is highly adapted for the high oxygen needs. So, the muscles of the hummingbird cause pressure changes within the air sacs. As a result, more oxygen can enter the respiratory system. Also, they have the highest density of red blood cells which allows them to rise heart beat to around 500 breaths per minute during flight.
