Name one star from the diagram that is fusing hydrogen into helium

Answer:

Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. Sometimes your body doesn’t make enough—or any—insulin or doesn’t use insulin well. Glucose then stays in your blood and doesn’t reach your cells.

Over time, having too much glucose in your blood can cause health problems. Although diabetes has no cure, you can take steps to manage your diabetes and stay healthy.

Answer:

Diabetes is the condition in which the body does not properly process food for use as energy. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.

Gallium Nitrite your welcome

A binary III/V direct bandgap semiconductor called gallium nitride is ideally suited for high-power transistors that can function at high temperatures. It has been widely utilized in light-emitting diodes (LED) since the 1990s. Its chemical formula is Ga(NO₂)₃.

Blu-ray discs are read using a blue light that gallium nitride emits. Gallium nitride is also utilized in lasers, photonics, RF components, and semiconductor power devices. GaN will be used in sensor technology in the future.

Gallium nitride power amplifiers are perfect for microwave and terahertz (ThZ) devices, such as imaging and sensing, the aforementioned future market, due to their capacity to operate at significantly higher temperatures and voltages than gallium arsenide (GaAs) transistors.

Explanation:

i don't have the periodic table in front of me right now but you will need it. for the first coloumn, look at the elemnt symbol and write it down. for example hydrogen H. the atomic mass will be written on the bottom of the entry. the atomic number is on the top. the number of protons is the atomic number. the neutrons is atomic mass-atomic number and the electrons you have to count the numbers in the upper right corner. depends what element you look at, there might be a couple rows of the electrons which are the shells. hope i helped :)

Answer:

E = 8.84×10⁻¹⁷ J

Explanation:

Given data:

Wavelength of wave = 2.25 nm (2.25×10⁻⁹ m)

Energy of wave = ?

Solution:

Formula:

E = hc/λ

c = 3×10⁸m/s

h =6.63 ×10⁻³⁴ Js

now we will put the values,

E = 6.63 ×10⁻³⁴ Js ×  3×10⁸m/s / 2.25×10⁻⁹ m

E = 19.89×10⁻²⁶ Jm / 2.25×10⁻⁹ m

E = 8.84×10⁻¹⁷ J

Answer:

A. To be precise, it must be able to make measurements repeatedly over a long period of time.

Explanation:

The precision of a scientific measuring tool can be defined as how close the values between multiple measurements are to each other, when repeated under the same conditions.

This ultimately implies that, the precision of a scientific measuring tool reflects the reproducibility and repeatability of its measurements, irrespective of how accurate the measurements are.

In science, one of the most effective ways to determine the precision of a scientific measuring tool is to find the difference between the highest and lowest measurements (measured values).

Hence, the statement which correctly describes a characteristic that a scientific measuring tool should have is that, to be precise, it must be able to make measurements repeatedly over a long period of time.

Explanation:

When the carbon dioxide concentration goes down, temperature goes down. A small part of the correspondence is due to the relationship between temperature and the solubility of carbon dioxide in the surface ocean, but the majority of the correspondence is consistent with a feedback between carbon dioxide and climate.

Answer:

The correct answer is - option b. We have discovered that atoms are made up of smaller particles, called subatomic particles.

Explanation:

Dalton made various postulates related to the atom which is an atomic theory that was first try to describe all properties of atoms. The major part of this atomic theory is that the atoms are unit that makes all the matter which is indivisible.

This postulate of the atomic theory is incorrect and changed as atoms are not indivisible and can divide into subatomic particles (proton, neutron and electron) however atoms are the unit that involves in reaction.

The way in which the atomic theory changed since John Dalton wrote his postulates is that: B. We have discovered that atoms are made up of smaller particles, called subatomic particles.

An atom can be defined as the smallest, indivisible, fundamental unit of matter that forms all chemical elements.  Thus, it is the fundamental (basic) building blocks of matter.

The first model of an atom was proposed by a notable English chemist called John Dalton. In the early 1800s, John Dalton adopted Democritus' theory to formulate the first model of an atom.

Dalton's atomic theory postulated that the atom of a chemical element as an impenetrable, indivisible, very small (tiny) but movable hard sphere i.e it cannot be divided into subatomic particles.

However, it has been established by other atomic model that an atom comprises three subatomic particles such as:

On Sept. 15, 2020, NASA, in partnership with Future Engineers, launched the Artemis Moon Pod Essay Contest. The contest, which is open to all (public, private, and home school) students in grades K-12, asks participants to imagine they are leading a one-week expedition to the Moon’s South Pole. In the essay, students will need to describe to NASA what (and who) they would bring to help make their expedition a success.

The Moon Pod Essay Contest is presented in support of NASA’s Artemis program. The student challenge is part of NASA’s efforts to engage the public in its missions to the Moon and Mars. NASA is returning to the Moon for scientific discovery, economic benefits, and inspiration for a new generation. Working with its partners throughout the Artemis program, the agency will fine-tune precision landing technologies and develop new mobility capabilities that allow robots and crew to travel greater distances and explore new regions of the Moon.
