Abnormally slow depolarization of the ventricles would most change the shape of the ________ in an ECG tracing. Group of answer

NeTakaya

Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.

The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.

Choose ALL correct "KEY DIFFERENCES" between Respiration and

Paladinen [302]

Answer:

Photosynthesis requires light energy, respiration does not.

Respiration occurs in all organisms, photosynthesis only occurs in plants, green algae, and some bacteria.

Respiration occurs in mitochondria, photosynthesis occurs in chloroplasts,

Respiration consumes glucose and oxygen, whereas photosynthesis produces them.

Oompah’s with type O blood receive a tax break. ophine oompah has type a blood, but he wants a wife that will give him children

vova2212 [387]

Answer:

He should request type O on his dating survey.

Opine's blood type must be AO to have a higher probability of producing O offsprings.

Explanation:

O blood type is recessive so, when it is paired with another blood type like B or A, these would be dominant, giving B and A blood, respectively.

O blood type results are possible thanks to OO genotypes.

If the man's blood type is A, to have a higher chance of producing OO offsprings, his blood should be AO. The other possibility is that he has AA blood, which will result in a low probability of OO offsprings.

As regards the mother, her blood type should be OO.

We can see this more clearly in Punnet Square.

║ A ║O

O║AO║OO

There is a 50% of probability of having O offsprings with AO and OO.

║ A ║A

O║AO║AO

O║AO║AO

With AA and OO, the probability is 0%

║ A ║O

A║AA║AO

O║AO║OO

With both parents having AO, blood the probability of having a OO offspring is 25%.

In conclusion, the higher chances of producing a OO offspring is if the parents are AO and OO.

When a gas is compressed, its volume__ does not change increases decreases

igomit [66]

Answer:w

when a gas is compressed, its' volume decreases.

Explanation:

When a gas is compressed, its volume usually decreases which also causes an increase in temperature. The pressure in addition increases which causes and increase of gas molecules. The molecules collide more frequently which is the reason why temperature will increase.

Can someone plz explain to me in a paragraph how can pythons affect the everglades.

madam [21]

Pythons are affecting everglades very negatively they are causing chaos in the food pyramid attacking all levels and not having predators prey on them pythons have become a huge problem that must be dealt with quickly because their affects are being felt quickly and very largely.
