Water quality testing would be the best approach.
Answer:
The correct answer will be option-E
Explanation:
The neuron is the functional unit of the nervous system which transmits the signals to and fro the tissue and nervous system. The neurons transmit the signals in the form of an electrical impulse as a result of the movement of the ions across the neuron.
When a neuron does not transmit any signal therefore it is known to be at rest but at rest, the movement of ions takes place but very slowly. The movement ions lead to the accumulation of sodium ions inside than outside whereas potassium ions are concentrated outside as compared to inner.
This charge difference leads to the disequilibrium in the charges and hence a potential gradient is created. This potential is known as resting potential.
Thus, option-E is the correct answer.
Answer:
4 chemicals
Explanation:
There are mainly 4 steps of gram staining.
1- crystal violet stain drained on the heat fixed slide.
2- then wash the slide and use iodine.
3- then wash the slide with water and use acetone as a decolorizer.
4- then use safranine as a counter stain.
So there are a total of 4 chemicals used named crystal violet, iodine, acetone, and safranine.
I think it’s C but not precisely sure about it
Your answer is D A kitten gains weight because they are similar because there both growing rather in height or weight because there both growing also its not A because that's an characteristic of a octopus is that it can camouflage with the floor and its not similar because it isn't growing in any way its also not B because a giraffe is eating a leaf off a tree is another example of a characteristic because of the giraffes long neck but its not growing in any way again its also not C because when a bee stings you your arm will swell up yes that's growing but it will soon go down and when it came down to rather D, or E I choose D because that's because its a sign of love or characteristic of a butterfly that's it removes pollen from its mate that's why I have chosen C. Your answer is C.
