Electromagnets can easily be turned on and off.
Explanation:
An electromagnet produces magnetic field which is done by the electric current. These electromagnets contain a wire would like a coil. The current passes through the wire and the magnetic field is concentrated in the center which is the "center of the coil".
When the current is "turned off" the magnetic field "disappears". This shows that we have can have a control over the passage of current or the magnetic field. Thus, the "main advantage" of the electromagnet is that it can be easily turned on and off whenever necessary.
A. they have a higher proportion of adenine–thymine than guanine–cytosine base pairs.
The option A represents the complete opposite of "high-gc gram-positive bacteria". High GC content means that this bacteria have more guanine ans more cytosine than the other base pairs- adenine–thymine. This means all the other options are correct.
Answer: State the hypotheses. Every hypothesis test requires the analyst to state a null hypothesis and an alternative hypothesis.
Formulate an analysis plan. The analysis plan describes how to use sample data to accept or reject the null hypothesis.
Analyze sample data.
Interpret the results.
Explanation:
Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.
<h3>Variations</h3>
Organisms of the same species can have different traits due to a difference in their proteins.
Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.
Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.

FAULT-TOLERANT computer systems are systems that are built with
the ability to keep working to
a level of satisfaction, even in the presence of faults within one or more of
its components. <span>This
fault tolerant ability is sometimes referred to as graceful degradation</span>
