Answer: The correct answers are option(b) and(d).
Explanation:
When the lamp was dimmer the resistance offered by the lamp was more which just resist the flow current from the circuit.
(Ohm's Law)
When the Janet decrease the resistance to (R') by sliding the dimmer switch (voltage remained constant). On decreasing the resistance the flow of current in circuit will increase by which light of the lamp will become brighter.
Hence, from the enlisted options the correct options option(b) and(d).
The correct answer is 30:(
Answer:
The epinephrine reaction is a decrease in the rate of blood flow in the arteriole and capillary, due to a phenomenon of vasoconstriction.
Explanation:
Epinephrine, or adrenaline, is a hormone produced by the adrenal cortex, which acts as a neurotransmitter for the sympathetic nervous system.
One of the effects of epinephrine is the <u>vasoconstriction of blood vessels, predominantly arteries</u>. Vasoconstriction of arterioles and closure of capillaries is an effect of epinephrine that results in a decrease in the rate of blood flow at that level.
This response can be seen when exogenous epinephrine is used to control an allergic or anaphylactic reaction, counteracting the vasodilation that characterizes these conditions.
Answer:
The answer is oil .
Explanation:
<u>Oil</u> is not a natural Earth cycle.

<span>Mosses receive their water from rainfall and most of their nutrients are dissolved in this water that has accumulated as dust on them. Their nutrient uptake is effected by the osmosis. Highly concentrated nutrients can kill them because they have no ability to regulate the absorption.</span>
