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.
Answer:
Soma or cell body
Explanation:
The cell body of a neuron is also called soma. Soma contains a nucleus surrounded by cytoplasm. Several cellular organelles such as lysosomes, mitochondria, and a Golgi complex are present in it. The presence of free and ER bound ribosomes allows cell bodies of neurons to form proteins for growth and regeneration of the damaged axons. Therefore, cell bodies serve as metabolic centers of neurons.
Dendrites of postsynaptic neurons obtain the nerve impulse from the axon of the presynaptic neurons and deliver it to the cell body. Axon of a neuron carries the nerve signals away from the cell body towards the dendrites or the cell bodies of the other neurons.
Answer: Neutral
solution
Neutral solution
have equal number of hydrogen ions and hydroxyl ions in a solution. Its pH is
naturally equal to 7 and the charge in that solution is neutral since the
concentrations are equal. In the event that the concentration is unequal, the
solution would have had a positive or negative charge.
Additionally, acidic
solutions have more hydrogen ions than hydroxide ions while an alkaline solution
contains more hydroxide ions than hydrogen ions.
Answer:
CTGTGTATCGTG
Explanation:
According to the rule of complementary base pairing proposed by Erwin Chargaff, the Adenine binds the Thymine and the Cytosine binds the Guanine.
In the given question,
if the base sequence of one strand will be- GACACATAGCAC
The complementary strand will be- CTGTGTATCGTG.
This option is chosen as this option fits the complementary base pairing rule and the is the most appropriate option.
Thus, CTGTGTATCGTG is correct.
Answer: That is false
Explanation: Catfishing is a deceptive activity where a person creates a fake identity on a social network account.
