Biology
2 answers:
NeTakaya4 years ago

Answer:

Hydrogen bond: It is a type of bond which exist between hydrogen atom and other atom having high value of electronegativity. Those atoms having high electronegativity values has the capability to attract the shared pair of electron towards itself. Hydrogen atom have very low value of electronegativity, so the shared pair of electron goes farther from it and nearer to high electronegative atom such as oxygen in water molecule. This bond is very weak than covalent bond.

It is not true bond due to weak force of attraction between atoms.

A hydrogen bond is the electromagnetic attraction created between a partially positively charged hydrogen atom attached to a highly electronegative atom and another nearby electronegative atom. A hydrogen bond is a type of dipole-dipole interaction; it is not a true chemical bond.

nucleus

mitochondria

ribosomes

lysosomes

endoplasmic reticulum

vacuole

Golgi bodies

Fracking collects _________ that forms when organic matter is compressed under great temperature and pressure.
Alexandra [31]

Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.

<h3>What is natural gas?</h3>

Natural gas is a mixture of gaseous hydrocarbons associated with petroleum deposits; mostly methane with smaller amounts of ethane, propane and butane; principally used as a fuel.

Natural gas is formed by the combination of compression and high temperature causing the carbon bonds in the organic matter to break down.

Therefore, it can be said that Fracking collects natural gas that forms when organic matter is compressed under great temperature and pressure.

Hostility is related to coronary heart disease and may contribute to premature death.
erik [133]

Answer:

True

Explanation:

Hostility can be explained in clear terms as a form of emotion portrayed in an aggressive manner, which is unfriendly and an arousal of anger from within as a result of denial or rejection.

Coronary heart disease occurs when major blood vessels that supply blood,oxygen,and nutrients  to the heat becomes damaged. It major cause are inflammation or cholesterol deposits in the arteries that supply all these nutrients, oxygen and  blood to the heart. This causes coronary arteries to narrow, limiting blood flow to the heart.  It is said that some slight modifications to care for coronary heart disease  include a better lifestyle changes,socialization etc, but when an individual susceptible to coronary heart diseases is hostile, it endanger the effect of such individual more to chronic effects.

Hostility levels is also related as  a better predictor of coronary heart disease risk than factors such as high cholesterol, high blood pressure etc. This is because more heart attacks are attributed to anger than high cholesterol.
