<h3><u>Answer;</u></h3>
Preload, afterload, and contractility
<h3><u>Explanation;</u></h3>
- Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload.
- Preload is the initial stretching of the cardiac myocytes or muscle cells prior to contraction. Afterload is the force or load against which the heart has to contract to eject the blood.
- Contractility is the intrinsic strength of the cardiac muscle independent of preload, but a change in preload will affect the force of contraction.
Answer:
abiotic
Explanation:
biotic is living abiotic is non living
The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.
Hope this helps!
