Answer:
Capillary refill time
Explanation:
Capillary refill time refers to the time that it takes for color to return to an external capillary bed after pressure has been applied (which causes blanching). Usually, on healthy individuals, capillary refill time takes less than 2 seconds. If the time is much longer, this could indicate problems such as shock, dehydration or peripheral artery disease.
The dissolved sugar molecules is distributed evenly all over the solution.
The equilibrium is reached through diffusion. Diffusion is the net movement of molecules and atoms from a high concentration to area of lower concentration. This is considered as the result of the movement of molecules. Diffusion is driven by a gradient until the molecules are distributed randomly and uniformly all throughout the solution. This can be manifested by perfume sprayed in the air, dye dropped in a water. The distinguishing features of diffusion is that particle move randomly and in uniform pattern.
Answer:
The cytochrome b6f is a large multi-subunit protein, which accepts electrons from the plastohydroquinone.
One electron moves linearly toward plastocyanin while the other goes through a cyclic process, which effectively pumps more protons into the thylakoid lumen.
Explanation:
The cytochrome b6f is distributed among both grana and stroma thylakoids equally. They are usually large and embedded in the membrane.
Answer:
Before the advent of modern biology, study of life and organism was in the realm of natural philosophy and was never in the club of classical sciences like physics, chemistry and engineering. Today biology is a science that studies life and living organisms.
Explanation:
A biologist can be categorized as a scientist because all the processes that supports scientific investigations are carried out in the study of biology- data collections, critical thinking, observation and collection of result for the purpose of public consumption.
On the other hand forensics is the mainly the aplication of science-mostly biology- in resolving criminal activities. It involves the collection of samples, anaylsing and presentaion of result for decison making.
Damage to heart valves can lead to heart murmur.
Explanation:
Heart murmur refers to the sound of blood flow. The sound of flowing blood in the heart is usually not heard.
The heart murmurs can result due to two reasons that is either a damaged valve or any condition that causes the heart to beat at a faster rate.
The types of damage to the heart valve that may lead to heart murmurs are:
Mitral valve prolapse, Mitral valve or aortic stenosis and Mitral or aortic sclerosis.
Sometimes, the murmurs do not signify a serious condition but under certain condition they may indicate the risk of heart failure.
