Answer:
True
Explanation:
Tetrodotoxin is the molecules that act as a poison to the organism in which they are injected.
The tetrodotoxin proves lethal to the organisms as it kills the organism by interfering with the nervous system. The tetrodotoxin blocks the sodium channels in the neuron as a result of which the sodium is unable to enter the neurons and hence the electrical impulse is not generated.
If the tetrodotoxin blocks the motor neuron transmission by blocking the sodium channels then the signals will not reach the muscle and muscle will not be able to contract.
Thus, true is correct.
Poor fitness can cause your heart to start disfunctioning, and not beating the way it should be. If an adult is not exercising often, they can end up having major heart problems that can affect the way they see their future.
It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.
But the truth is no one really knows for certain so the only thing we know is that the spin of the earth is the cause of its magnetic field
Hope this helped :)
Have a great day
Some are:
-laws tell how
- laws are proven true
- Theories attempt to explain
- Theories are developed based on likely true things, but not necessarily proven
- hypothesis is an educated guess
- hypothesis is made before your test/experiment.
- laws are formed after tests and experiements.
- Theories are often based off of tests/experiment, but again, not necessarily proven to be true.
Answer:
The correct answer is the second option - glycerol and fatty acids combine to form lipids.
Explanation:
Lipids are a polymer or macromolecule, and the smaller pieces, or monomers, that make up lipids are glycerol and fatty acids.
Option 1 is incorrect because nucleotides are the monomer for nucleic acids, not proteins.
Option 3 is incorrect because amino acids combine to form proteins, not nucleic acids.
Option 4 is incorrect because polysaccharides are polymers (the monomer for carbohydrates is monosaccharides).
Hope this helps!
