Answer:
The different skeletal muscle fiber types vary in the speed and duration of their twitches due to -
b) They vary in the rate of hydrolysis of ATP
c) They vary in the removal of Ca+ from the cytosol
Explanation:
There are mainly two types of muscle fibers , i.e.
a) slow twitching, long contraction duration( type I fibers)
b) First twitching but short duration of contraction. ( type II fibers).
Now think of the physiology of muscle. Two components are important, cytosolic Ca++ concentration and Availability of ATP. K+ is related to the action potential ( none or all law, there is no relation to the duration with respect to the potassium). For long contraction muscle fibers need a more steady supply of ATP, and also consistent high concentration of cytosolic Ca++ for muscle contraction to happen. So, these two factor is important for the duration of twitching. So the answer is option f .
Answer:
False.
Explanation:
Intravenous drug administration consists of applying a drug directly into the patient's vein. This type of drug administration promotes more accurate observations on the drug's effects on the patient's body and on the drug's effectiveness in fighting the disease, mainly because intravenous administration allows the drug to act faster, even when applied in large volumes.
Answer:
Etymology of
Soma
from Greek sōma ‘body’.
Cell's body, this part of the cell receives information, and it contains the cell's nucleus.
Etymology of dendrite
from French, from Greek dendritēs ‘treelike’, from dendron ‘tree’.
thin filaments carry information from other neurons to the soma, they act as input part of the cells
Etymology of Axon
(denoting the body axis): from Greek axōn ‘axis’.
long projection carries information from the soma and sends it off to other cells. This is the “output” part of the cell.
Incorporate more schools that serve breakfast.
The Department of Health and Human Services in the US has proposed a program called Healthy People 2020 to encourage the prevention of acute and chronic illness for all US residents.
One of the more than 1300 specific goals of Healthy People 2020 is to increase the number of schools that serve breakfast. This is a crucial goal because, regrettably, not all parents provide their kids with a healthy breakfast because of financial hardship, carelessness, etc.
Children would benefit from breakfast being served at school either for free or at a reduced cost since they would start the day with nourishment and better health and nutrition from a nutritious breakfast.
