Suppose you have had kidney stones, and you want to see the outside of a kidney stone, in three dimensions, to see why it causes so much pain leaving the body. What microscope would be best suited to this purpose

Answers

A scanning electron microscope (SEM) would be the best option for viewing a kidney stone's exterior in three dimensions.

Thus,  SEMs use a focussed electron beam to scan the specimen in order to provide finely detailed three-dimensional images of the specimen's surface.

This enables high-resolution imaging of the kidney stone's exterior features, revealing details on its composition, structure, and surface characteristics.

For examining the microstructure of materials and biological samples, SEMs are extensively employed in a wide range of scientific and medical applications.

Answers

The erythema and swelling can be explained at a cellular level by all except increased vasomotor tone (vasoconstriction) of the capillaries in the area. Erythema causes skin redness.

What is erythema?

Erythema refers to skin redness due to injury and/or inflammation in a given region of the body.

Erythema may be due to different factors (e.g., environment, virus infection, sunburn, etc).

Conversely, vasoconstriction refers to constriction of the blood vessels, which is caused by their cells walls.

where dose the extra electron in a negatively charged atom come from? pls help

Answers

A negatively charged atom is called an anion. This just means it has gained electrons (negative charges) and the atom has become negative instead of neutral since number of protons = number of electrons. Now it has 1 or more extra electrons, it is more negative than positive or neutral.

Description

Definition: Doppler Effect refers to the change in wave frequency during the relative motion between a wave source and its observer. It was discovered by Christian Johann Doppler who described it as the process of increase or decrease of starlight that depends on the relative movement of the star.

Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down. The drop in pitch of ambulance sirens as they pass by and the shift in red light are common examples of the Doppler Effect.

Edwin Hubble made the discovery that the universe expands as a consequence of the Doppler Effect. It has important applications in the fields of astronomy and space technology.

Amed watched a video of someone using a jetpack rocket at a lake. Water is pumped out of the lake into the jetpack, and then the water is fired out of the jetpack, as shown in the picture. The rider is lifted out of the water and can move around over the lake.

Explain how the height of the rider above the water could be increased. Support your
explanation using Newton’s third law of motion.

Answers

Answer:he rider could be lifted higher above the water by increasing the force of the water fired out of the jetpack. This force is equal in strength to the reactive force in the opposite direction. The reactive force lifts the rider out of the water. Newton’s law of motion states that for every force there is an equal and opposite reactive force.

Explanation:

The height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.

What is Newton's third law?

Newton's third law says that when two bodies interact, they apply equal and opposite force on each other.

In the jetpack rocket, the man goes higher due to the force applied by water in the down direction, and the man is going up according to the third law of Newton.

Thus, the height of the rider could be increased by the increase in force of water. The newton's third law says that every force has equal and opposite reactive force.

How does the environment influence development?

The environment influences development by altering a biological process known as cellular differentiation.

Differentiation is a process by which cells divide to develop specific cell types, which depends on differential gene expression patterns influenced by environmental conditions.

During growth, environmental factors and genetic factors work together to shape developmental programs in an organism.

According to the author, what was one reason Alfred Thayer Mahan thought control of the Pacific Islands was important to the development of the United States?. . . Mahan was not in the vanguard [forefront] of those imperialists in 1898 who, like Roosevelt, Lodge, Senator Albert J. Beveridge, of Indiana, and others, saw in a victorious war with Spain for Cuba Libre [independence] an opportunity also to annex the distant Philippines. Mahan had seen since 1896 both the need and the opportunity for American commercial expansion in the Pacific and into the markets of China. But there is no persuasive evidence that he linked the annexation of the entire Philippine archipelago with that particular goal. The acquisition of naval coaling stations at Manila, in Guam, and at the mouth of the Yangtze he deemed entirely adequate to sustain future American commercial ambitions in China.To be sure, he had long advocated the annexation of Hawaii, his arguments invariably [always] centering on defense of the Pacific coast, control of Oriental immigration, and the strategic implications of Japanese expansion into the Central Pacific. He had again demanded Hawaiian annexation as recently as February 1898 when Senator James H. Kyle, of South Dakota, asked him for a statement on the strategic virtues and values of the islands. He cheered in July 1898 when the United States, almost as a national-defense reflex, blinked twice, gulped, and finally swallowed whole the Hawaiian group.
