Sample A most likely came from the left ventricle, as this is the portion of the heart that receives freshly oxygenated blood to be pumped to different parts of the body. Oxygenated blood is blood that has had oxygen bounded to it by hemoglobin (a pigment made of iron found in red blood cells). The oxidation of this blood by the iron in the hemoglobin gives it the RBC bright red look. This blood containing the bright RBCs in transported to the left ventricle from the lung, after which it is spread throughout the body. Hence, in normal conditions of the heart, the Sample A most likely came from the left ventricle.
The correct sequence of events is : C,D,B,A.
Iron rich magma in the earth's core heats up because of radiation and the pressure exerted by the other layers of the earth. This heat in the crust trigger convection currents in the mantle. The magma closest to the core will be hotter and therefore less dense than other layers. Being less dense the layer will rise towards the crust, eventually becoming cooler and sinking back down in a circular motion.
The continued circular motion creates electric currents which then generates the magnetic field.
My answer is A i hope this really helps u!
<span>The three daily activities that affect homeostasis include;
Temperature, glucose levels, ability lymphatic system.
Homeostasis is the tendency of organisms to auto-regulate and also maintain an internal environment within a stable state. The stable condition is when the optimal functioning of organisms and dependant on many variables.
For example, fluid balance and body temperature to be kept within certain preset limits. PH of extracellular fluid, potassium, calcium ions and concentration of sodium and blood sugar levels are also variables.
It is needed to be regulated despite the diet, environment, level of activities. They are controlled by homeostatic mechanisms which when comes together maintains life.</span>
Answer: When you study environmental science, you commit to learning of accomplish important tasks for our Earth and our human population.
Explanation: Hope this helps! :)
