A polarizing camera has a great affect on photo quality. When using a polarizing camera, skies are often darkened, reflections are controlled, and glares are often brought down or suppressed. Hope this helped :)
Answer:
8.18 × 10 ⁻²¹.
Explanation:
The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.
The change in the potential energy can be calculated as follows:
W = v2-v1 × q.
Here, the charge of the proton is considered because k+ ions has been used.
W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.
W= 8.18 × 10 ⁻²¹J.
Thus, the answer is 8.18 × 10 ⁻²¹.
I think the answer is d not quite sure tho
They provide the immune system with "memory" against previously encountered pathogens.
T memory cells are necessary for protective immunity against invading pathogens
The two samples must be independent and each must be drawn at random from any population. The two samples must be independent and each must be drawn at random from a healthy population.
At the very least, nominal scale data are required. There must be normal populations. There must be knowledge of the two population standard deviations. The samples depend on one another.
<u>What is nominal scale?</u>
A nominal scale is a measurement scale that is used to categorize events or things into distinct groups. This type of scale only needs one-of-a-kind identifiers to mark each separate category instead of requiring the usage of numerical values or categories ranked by class.
