Anaerobic respiration is when organisms don't use oxygen to breathe. That occurs in organisms such as yeasts. Usually, the higher the temperature the more anaerobic respiration occurs.
Answer:
E. that area of the membrane is in the absolutely refractory period.
Explanation:
Refractory period is a period during which neuron cell cannot be stimulated (depolarized). This is why the action potential can only travel in one direction from the neuron body towards axon.
Refractory period occurs because of the inactivation of voltage-gated sodium channels (while action potential is at its peak) which cannot be open for a certain period of time. and membrane cannot be depolarized.
The answer is any cell from the same organism.
Answer:
Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
Explanation:
Answer:
Adverse heart conditions do not occur in isolation. It is usually accompanied by other risk factors, like coronary artery dysfunction, diabetes, high blood pressure, etc.
In addition to the above, the following factors are indicative of left-sided heart failure:
- Shortness of breath caused by the collection of fluid in the lungs. Shortness of breath usually becomes pronounced upon physical exertion
- An increase in the girth of the torso (mainly the abdomen) due to ascites which is the buildup of fluid in the abdomen.
- engorged scrotum (in males of course)
Explanation:
Left-Sided Heart Failure is simply the inability of the heart to pump oxygen-rich blood into the body.
Blood filled with oxygen is moved from the lungs to the atrium on the left and then to the left ventricle. The blood is then pumped from the ventricle on the left to other parts of the body by a contracting and relaxing action. Left-sided heart failure can be classified into two:
- Systolic Failure and
- Diastolic Failure
1. Systolic Dysfunction: When the left ventricle can no longer shrink properly, the pressure with which the heart can pump enough blood into circulation is reduced.
2. Diastolic Dysfunction: This occurs when the left ventricle can no longer relax as it ought to due to the hardening of the muscle.
