With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Answer:
Cholesterol is a waxy substance found in your blood. Your body needs cholesterol to build healthy cells, but high levels of cholesterol can increase your risk of heart disease.
With high cholesterol, you can develop fatty deposits in your blood vessels. Eventually, these deposits grow, making it difficult for enough blood to flow through your arteries. Sometimes, those deposits can break suddenly and form a clot that causes a heart attack or stroke.
Explanation:
High cholesterol can cause a dangerous accumulation of cholesterol and other deposits on the walls of your arteries (atherosclerosis). These deposits (plaques) can reduce blood flow through your arteries, which can cause complications, such as:
Chest pain. If the arteries that supply your heart with blood (coronary arteries) are affected, you might have chest pain (angina) and other symptoms of coronary artery disease.
Heart attack. If plaques tear or rupture, a blood clot can form at the plaque-rupture site — blocking the flow of blood or breaking free and plugging an artery downstream. If blood flow to part of your heart stops, you'll have a heart attack.
Stroke. Similar to a heart attack, a stroke occurs when a blood clot blocks blood flow to part of your brain.
Radiation is spontaneously emitted from hydrogen-3 nuclei, but radiation is not spontaneously emitted from hydrogen-1 nuclei or hydrogen-2 nuclei. Which hydrogen nuclei are stable
The hydrogen nuclei that are stable are hydrogen-1 nuclei or hydrogen-2 nuclei because radiation is not spontaneously emitted from them. Only the hydrogen – 3 nuclei is spontaneously emitted by radiation.

The compound that has both ionic and covalent bonding is .
Further Explanation:
The attraction between different atoms, molecules and ions is known as a chemical bond. The formation of various types of compounds takes place as a result of these chemical bonds.
An ionic bond is formed as a result of the interaction between a metal and a non-metal. Metals have the tendency to lose electrons while non-metals tend to gain electrons. Due to this, metal atoms form cations by loss of electrons and non-metals become anions with the gain of electrons.
A covalent bond is formed by the mutual sharing of electrons between the bonded atoms. It is also called the molecular bond. Such bonds usually exist between two or more non-metals.
(1)
Its constituents are and ions. The bond between calcium and carbonate ions is an ionic bond. But the bond between the carbon atom and the oxygen atom of carbonate is formed by sharing of electrons so it is a covalent bond. So has both ionic and covalent bonding and therefore this option is correct.
(2)
It has carbon, hydrogen and chlorine atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.
(3)
It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.
(4)
It has carbon, hydrogen and oxygen atoms. All of them are nonmetals and the bonds formed between nonmetals are covalent bonds. So has only covalent bonds and therefore this option is incorrect.

CaCO3 is the substance that contains both ionic and covalent bonds. Calcium ions (Ca2+) and carbonate ions (CO3-2) make up the salt known as CaCO3. Ionic bonds, which are created when one atom donates electrons to another atom, are what bind the calcium and carbonate ions together.
Three oxygen atoms and one carbon atom, linked together by covalent bonds, make up the carbonate ion. The three oxygen atoms and the carbon atom share electrons to create a covalent connection. Atoms exchange electrons to make covalent connections, whereas atoms give away electrons to produce ionic bonds.
In CaCO3, an ionic connection is created when the calcium atom donates electrons to the carbonate ion. The carbon atom shares electrons at the same moment.

The Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.
If the average value of different measurements is similar to the correct value of the measurement is said to be accurate and if the value of different measurements is close to each other then it is said to be precise.
The everage value of the different measurements may or not may be the same as exact and the resultant values must be the same as the calculated value for the precision of the result.
Therefore, the Precision of a calculated answer is limited by the least precise measurement used in the calculation is false.

What are the variables in his hypothesis?
Answer:
im not sure about the answer but i did the test and "The independent variable is the number of dry cells, and the dependent variable is the amount of energy available."is wrong
B. 12 carbon atoms
C. 24 carbon atoms
D. 3 carbon atoms
The fewer the carbon atoms, the closer it is to being a gas. The only one you have to check out is A which is hexane. You know that gasoline at the pumps has 8 carbons and its a liquid. So B and C are both not gases because they are above 8.
C6 (hexane) is a liquid at room temperature not a gas.
The answer is D. If there is a gas present, it must be C3
