Coal is formed when layers of plant matter accumulate at the bottom of a body of water and are protected from biodegradation and

oxidization. Over time, the properties of the original material change. What evolutionary significance, if any, does this have?

The evolutionary significance is that coal does not change the properties of the plant from that time even though the plant might have evolved from that time. That's why you can study coal to find out how the type of plant was at that time period and how it has evolved until now.

One of the reasons for this is that our unconscious handwriting incorporates into it different mental, physical, and mechanical
Liula [17]

Answer:

The correct answer is: True.

  • The writing of a person is controlled by an region located in the left part of frontal lobe of the brain which is known as the Broca's area.
  • Writing is a motor impulse send by the brain to the hand and fingers.

  • It also depends upon the psychology, mentality, thought process, state of mind, nature of the person and also the influence of the surroundings on the person.
  • It also depends on the preference of the person to keep his writing artistic or simple or illegible.

A group of students wanted to compare the rate of respiration in four different fruits, as well as in tomatoes.
Brilliant_brown [7]

In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.

<h3>What is a dependent variable?</h3>

A dependent variable is any type of experimental condition that is modified during the experiment.

Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).

Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).

In conclusion, the dependent variable is the rate of respiration.
