Answer:
A major advantage of cohort studies over case-control studies with respect to the role of a suspected factor in the etiology of a disease is that they permit direct estimation of risk of disease in those exposed to the suspected factor.
Explanation:
The major advantage of cohort studies over case control studies are :
1.It is suited for rare exposures since starting with exposure status.
2.Allows for studying several outcomes.
3.Exposure status easier to ascertain since starting point of the study.
4.Allows computation of risk and rates.
5.Allows studying natural history of disease, easier to show that cause precedes effect.
6.Easiness to find a reference group
, usually not difficult to identify an unexposed population.
7.Sample size taken is large.
8.Concept
s are easy to understand.
Explanation:
Anaerobic Resistance Training: In this training high intensity, intermittent bouts of exerciese sare done wgich include weight training, interval training, speed, agility, and plyometric drills.
Aerobic Exercise Training: It is physical exercise in which exercises are done from low to high intensity which further depends on the aerobic energy-generating process.
following items would be altered following a lengthy training program are as follwoing:
- Myofibril size and number - Increase with Anaerobic Resistance Training
- Lactic acid processing - Increase with Anaerobic Resistance Training
- Muscular density of blood capillaries - Increase with Anaerobic Resistance Training
- Blood volume and red blood cell count - Increase with Aerobic Exercise Training
- Long-term fatigue resistance - Increase with Aerobic Exercise Training
- Muscle size - Increase with Aerobic Exercise Training
- Mitochondrial density - Increase with Aerobic Exercise Training
Answer:
The answer to the question: There are neurotransmitters that can be both excitatory and inhibitory. Explain how this is possible, would be, Yes, there are some neurotransmitters such as acetylcholine and dopamine, who have both an excitatory and inhibitory effect in other neurons and in cells, and this happens because of the type of receptors they bind to, and the type of cell where they bind.
Explanation:
Neurotransmitters are the messengers, or communication system that the nervous system in general has with itself and with other systems. There are several types of these, and some work both as neurotransmitters and as hormones as well. How they act, where they act, and what kind of response they elicit, depends entirely on the receptors to which they bind, when they are released by a pre-synaptic neuron. Most neurotransmitters are either excitatory, or inhibitory, and some are known as neuromodulators. However, there are two types known today that work as both excitatory and inhibitory: dopamine and acetylcholine. How can either of these act as each of these? Depends on the receptors present on the post-synaptic neuron, or cell, and depends on the type of cell as well. As soon as these two bind to their appropriate receptors, in a specific kind of cell, they will produce the specific response from the cell, either starting an action potential, ir inhibiting it from happening.
