Park Jimin is always the answer :) jk its 100%
The answer is size. The larger
the DNA molecule the slower it travels through the gel. This is because
of the restriction of their movement through the pores of the gel. The smaller DNA molecules travel furthest. The size
of the pores can be varied through by changing the mixture ratios of the agarose gel.
250 represents the 100% of calories on the potato chips.
If you want to know the percentage that represents 150 calories from fat, then you have to multiply 150 calories (calories from fat) by 100% (the total percentage of calories) and then divide the outcome by 250 calories (the total calories on the potato chips):
(150 cal*100%)/250 cal= 60%
Answer:
The correct answer is: Electrical impulses in the heart cause the muscles to contract.
Explanation:
The heart contracts thanks to a series of electrical impulses that travel through the muscles of this organ. The electrical impulse begins in the SA (sinoatrial) node and is transmitted to the muscles that conform the left and the right atria to produce their contraction which will make the atria pump the blood to the ventricles. When the electrical impulse reaches the AV node and then the Bundle of His, this information will transmit to both ventricles and will produce their contraction as well.
The only muscle tissue capable of stimulating their own contractions is the muscle in the heart, the myocardium, thanks to the existence of "pacemaker cells" that are located in the SA node.
The waves in the ECG represent the depolarization of the atria, depolarization of the ventricles, and repolarization of the ventricles.
Answer:
One of the most colorful images taken of the Moon, this NASA compilation shows shades of green and brown in addition to gray. Many Moon photos are actually color images! Unfortunately, unlike the planets, the Moon's surface has no brightly colored areas. Most of its color is a mix of dark browns, grays, or black.
Is it multiple choice?
