Ventricular tachycardia has the greatest chance of deteriorating into a pulseless rhythm in cardiac dysrhythmias.

A cardiac dysrhythmia may also be called a cardiac arrhythmia or an irregular heart rhythm.Cardiac dysrhythmia (arrhythmia) is an irregular or irregular heartbeat. If you have dysrhythmia, your heart may beat too fast or too slowly. Or your heart rhythm may be disrupted, leading you to feel like your heart is skipping a beat. Although dysrhythmias can be harmless, they can cause serious health problems if left untreated. The words dysrhythmia and arrhythmia are different especially in linguistic sense. A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. Heart arrhythmias occur when the electrical signals that regulate the heartbeat do not work properly.

What part of the respiratory system do you think is most important? Provide a thorough explanation to support your answer.

Luden [163]

Answer:

The most important are the lungs, more precisely the alveoli.

Explanation:

Alveoli are structures of the lungs where gas exchange occurs. They allow oxygen from the air to pass into blood. Oxygen diffuses through the walls of alveoli into the capillaries that surround it. Oxygen is then bonded with the iron in red blood cells and travels to the heart. The heart then sends the oxygenated blood out to all the cells in the body.

Of the total amount of glucose energy consumed by the body each day, about what percentage is used by the brain and nerve cells?

Alexeev081 [22]

Of the total amount of glucose energy consumed by the body each day, about 20% is used by the brain and nerve cells.

The brain constitutes about 2% of the total body but it is one of the main consumers of energy derived from glucose.

The energy provided by glucose is used for the proper functioning of the brain. It generates ATP which is an energy source that is responsible for r neuronal and non-neuronal cellular maintenance and generates neurotransmitters.

Thus glucose-derived energy is critical for the health of the brain. Lack of energy can cause several brain diseases.

900J

Explanation:

Given parameters:

Specific heat of the aluminium = 900Jkg⁻¹K⁻¹

Mass of aluminium = 0.5kg

temperature change = 2K

Unknown:

Quantity of heat = ?

Solution:

The quantity of heat a body absorbs to cause a change in temperature is given as:

H = mcΘ

H is the quantity of heat

m is the mass of the substance

c is the specific heat capacity

Θ is the temperature change

H = 0.5 x 2 x 900 = 900J

One of the grand challenges in biology is understanding how the first cells formed on Earth. Since all cells are bound by a cell

coldgirl [10]

<h2>Answer is option "A"</h2>

Explanation:

Oils and fats, which in science are called lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side. While the hydrophilic sides of a lipid will associate with the water in a solution, the hydrophobic sides of the lipid all cluster together to 'hide' from the water. Lipids therefore cluster together and form spheres where the hydrophobic sides are in the center away from the water while the hydrophilic sides are on the outside, associating with the water.
The ability of the atoms within a group to form hydrogen bonds with the water molecules around them makes them hydrophilic. Oxygen and nitrogen atoms readily form hydrogen bonds with water molecules, so any organic molecules that have oxygen or nitrogen atoms bound to their carbon skeletons will be hydrophilic.
For example, if we take the molecule for cholesterol, we see the OH group on the left is hydrophilic and will form hydrogen bonds with water, while the ring structures, which only consist of hydrogen and carbon atoms, are hydrophobic and will not associate with the water.
There are many different kinds of lipids with different functions. Lets start by examining phospholipids, which compose the cell membranes of animals. They form lipid bilayers, with one set of hydrophilic heads facing the exterior of the cell membrane and the other set facing the interior (as you can see on the diagram on screen). The hydrophobic portions of the lipid bilayer - the lipid tails - face towards one another, which allows them to hide away from the water inside and outside of the cell.
So,the right answer is option A "amphipathic molecules".
