phenotype is correct because its physically characterized.
Plant cells have plastids and larger vacoule and they also have tough cellulosic cell wall outer to cell membrane as a covering.
Animal cells don't have cell wall rather they have cell membrane as it's outermost covering and they have smaller vacuoles.They also don't have plastids.They have centrosome which is not found in plant cells.
The right answer is spongy bone (cancellous bone).
In otosclerosis, the new bone blocks the movement of the stirrup, causing transmission hypoacusia. Otosclerosis can also cause perceptive deafness, especially when otosclerotic bone foci are close to scala media. Half of all cases are hereditary. The measles virus may play a role in triggering a genetic predisposition to otosclerosis.
Answer:
ventricles contract and movement of blood is towards the body in systolic blood pressure and ventricles relax and movement of blood is towards heart in distolic blood pressure.
Explanation:
Blood pressure is the pressure exerted by blood on the walls of blood vessels. The standard blood pressure in human adults is 120/80.
During Systolic blood pressure, the heart <em>ventricles contract</em> and pump the blood to arteries, arterioles, capilaries then venules and veins from an area of higher pressure to lower pressure. Simply, the heart pumps the oxygenated blood towards the body. It is the higher value (120).
The Diastolic blood pressure is lower arterial pressure (80) and produced during <em>ventricular relaxation</em>. During diastolic blood pressure, the heart refills it and thus deoxygenated blood move towards heart from body.
