Answer:
A. repetition of their physical and chemical properties when arranged according to increased atomic number
Explanation:
Answer is: <span>A. spontaneous reactions release.
</span>
ATP
is short for adenosine triphosphate<span>
Adenosine triphosphate converts to either
the adenosine diphosphate (ADP) or adenosine monophosphate
(AMP), in this process energy is released (for example </span> glycolysis, the citric acid cycle or oxidative phosphorylation and beta-oxidation).
ATP is made of three components: the
triphosphate, the sugar ribose and a nitrogenous base (adenine).
Answer:
Hope it helps.
Explanation:
It decays by beta particle emission into xenon-131. After eight days have passed, half of the atoms of any sample of iodine-131 will have decayed, and the sample will now be 50% iodine-131 and 50% xenon-131
Answer:
C
Explanation:
What causes blood pressure?
C
To pump blood around the body, the heart contracts and then relaxes through the cardiac cycle. The cycle begins with the contraction of the two atria, which push blood into the ventricles. Then, the ventricles contract, which forces the blood out of the heart.
When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure.
When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.
Put the marked magnet up to each side of the unmarked one. if they attract they are opposite -north attracts south, south attracts north- if they repel -forcefully push away- from each other they are the same -north and north, or south and south. once you have done that you can label the poles correctly.
