Gold atoms can be identified based on the number of which subatomic particles?
A.neutrons
B.electrons
C.nuclei
D.protons

Answers

Answer 1

Answer: A

Explanation:

A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far. 79 is its charge (atomic number), which is both its proton number and electron number

Answer 2

D. Protons, if you change the number of protons you change the element. You cannot change nuclei. You can have the same element with different numbers of neutrons (isotopes) and different numbers of electrons (ions). So protons will allow you to identify the element.

What is an ellipse please help)

Answers

normal oval shape traced by a point moving in a plane so that the sum of the distance from the other points is constant.

In mathematics, an ellipse is a plane curve surrounding two focal points, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body

Answers

Answer:

The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Answer:

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?

Answers

Answer:

Explanation:

Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.

This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.

In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.

Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.

Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.

Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.

The mass of Betelgeuse is about ___ times the mass of Vega

(This is not multiple choice.)

Answers

Betelgeuse is a red supergiant star located in the constellation Orion, while Vega is a main-sequence star located in the constellation Lyra. The mass of Betelgeuse is estimated to be about 20 times the mass of the Sun, while the mass of Vega is estimated to be about 2.1 times the mass of the Sun. Therefore, the mass of Betelgeuse is about 9.5 times the mass of Vega.

Therefore, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.

Vega is a main-sequence star located in the constellation Lyra. Betelgeuse is a red supergiant star located in the constellation Orion. The mass of Betelgeuse is observed to be about 20 times the mass of the Sun, while the mass of Vega is estimated to be about 2.1 times the mass of the Sun. Therefore, the mass of Betelgeuse is theoretically estimated to be around 9.5 times the mass of Vega.

Experimentally,

The mass of Betelgeuse is 2.188 x10^31 kg

The mass of Vega is 4.246 x 10^30 kg

Hence, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.
