Answer:
5- action potential 6- receptors 7- calcium ions 8- sarcolemma
Explanation:
This description illustrates the pathway of a action potential traveling along a neuro-muscular junction. this functions as a chemical synapse between a motor neuron and a muscle fibre. It allow the motor neuron to transmit a signal/action potential to the muscle fiber, causing muscle contraction.
Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.
The carbon containing molecules in the giant kelp come from carbondioxide, wastes and other carbon containing simple molecules.
Answer: Option C.
Both
Explanation:
Streptomycin is an antibiotics produced from bacteria and fungi and it is used to treat bacteria infections (prokaryotic ) such as tuberculosis, mycobacterium infection e.t.c.
It's inhibit protein function in prokaryotes because it's affects the function and performance of 70 s RIBOSOMES which is an organelles for protein production.
Streptomycin does not affect eukaryotes because it does not bind to the RIBOSOMES of eukaryotic cells which in turn does not affect protein production.
Answer: Workplace electrocusion
Explanation:
The human body is a good conductor of electricity. The workplace electrocution occurs due to electric shock. This leads to workplace injuries that may often lead to disabilities and can also be fetal. The workplace electrocution can also lead to cardiac arrest, and tissue damage due to thermal burns. The severity of injuries may depend upon the intensity of electricity, health of the victim and how the current flows in the body.
According to the given situation, the freshly mopped floor is a source of water and water, as well as metal, which is a good source of electricity. The electric wire is an energized source of electrical energy that will allow the flow of electric current in the body, as well as contact with the floor containing water, which will enhance the effect. Thus this is an example of workplace electrocution.
