I'M HAVING A FULL MELTDOWN plz and thank you<3 Which statement about gamma radiation is true?

Question 3 options:

Gamma radiation has the longest wavelength and lowest frequency of the electromagnetic spectrum, giving it the most energy

Gamma radiation is in the center of the electromagnetic spectrum, so it has a medium amount of energy compared to the other parts of the spectrum

Gamma radiation has the highest frequency and shortest wavelength of the electromagnetic spectrum, so it has the least energy

Gamma radiation has the highest frequency and shortest wavelength of the electromagnetic spectrum, so it has the most energy

Which type of signal is has a step-like appearance because it is composed of precise values of "this or that" with nothing in between?

Question 5 options:

digital signals

dial-up internet

vinyl records

analog signals

Explain how the integumentary system plays a crucial role in the ability to maintain homeoestasis

Nanotechnology, the field of trying to build ultrasmall structures one atom at a time, has progressed in recent years. one potential application of nanotechnology is the construction of artificial cells. the simplest cells would probably mimic red blood cells, the body's oxygen transporters. for example, nanocontainers, perhaps constructed of carbon, could be pumped full of oxygen and injected into a person's bloodstream. if the person needed additional oxygen-due to a heart attack perhaps, or for the purpose of space travel-these containers could slowly release oxygen into the blood, allowing tissues that would otherwise die to remain alive. suppose that the nanocontainers were cubic and had an edge length of 24 nanometers. part a part complete what is the volume of one nanocontainer? (ignore the thickness of the nanocontainer's wall.) express your answer using two significant figures. v v = 1.4ă—10â’20 l previous answers correct significant figures feedback: your answer 1.3824â‹…10â’20 = 1.382ă—10â’20 l was either rounded differently or used a different number of significant figures than required for this part. if you need this result for any later calculation in this item, keep all the digits and round as the final step before submitting your answer. part b suppose that each nanocontainer could contain pure oxygen pressurized to a density of 81 g/l . how many grams of oxygen could be contained by each nanocontainer?
