Answer:
Hypertonic
Explanation:
The <u>hypertonic environment</u> is an environment in which the <u>number of solute (salt) particles outside the cell are greater</u> than their number inside. In other words, if the extracellular fluid has a higher salt concentration than the cell’s internal environment (cytoplasm), the condition is called as hypertonic. The word "hyper" means "greater".
In a hypertonic environment, <u>water</u> from the cell's internal environment <u>moves outside</u> the cell <u>to dilute the outer concentration</u>. This is because of fundamental principles of <u>homeostasis</u> where maintenance of internal environment with respect to the external environment is very crucial.
In contrast to the hypertonic environment is the hypotonic environment in which there is more salt concentration inside the cell than the outside. Thus, water will move inside the cell to dilute it further. This condition sometimes leads to bursting of the cell because of continuous water movement inside the cell.
The answer is D. 3.33 A
In parallel connected devices, circuits are also placed parallel. It is known that in parallel circuits, total voltage is equal to the voltage of each device.
So, we know that:
Device 1 - R1 = 12 ohms
Device 2 - R2 = 4 ohms
Total voltage - V = 40V = V1 = V2
If V = I × R, for the first device is V1 = I1/R1.
⇒ I1 = V1 ÷ R1
⇒ I1 = 40 V ÷ 12 ohms
⇒ I1 = 3,33 A
