Pests have always been a nuisance for farmers. The use of pesticides dramatically improved the success of crops; however, it has

been found that some insects are no longer harmed by traditional pesticides. How would Charles Darwin, the man behind the theory of evolution by means of natural selection, explain this phenomenon.

Pretend scientist discover an enzyme in the human body that works best at 39 degrees Celsius. What process would this enzyme mos
Ymorist [56]

Answer:

The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.

The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.

The graph represents velocity vs. time for Carla. A graph with horizontal axis time (seconds) and vertical axis velocity (meters
kherson [118]

Answer:

The statement that best describes the graph is Carla slowed down in the beginning of her trip, stopped, and then sped up.

Explanation:

Data:

Horizontal axis = time.

Vertical axis = velocity (m/s).

A line runs in straight segments

  • <em>from 0 seconds 15 m/s.</em>
  • <em>to 1 seconds 13 m/s.</em>
  • <em>to 2 seconds 10 m/s.</em>
  • <em>to 3 seconds 4 m/s.</em>
  • <em>to 4 seconds 0 m/s.</em>
  • <em>to 6 seconds 4 m/s.</em>

According to the data present in the graph, it can be seen that Carla starts with a speed in her career, which decreases over time. After four seconds she stops, remains stopped for one second and starts running again, with an initial speed of 4 m/s.

<em>In conclusion, the graph show Carla -who is moving- slows down until she stops, and then starts the race again.</em>
