Parasympathetic tone holds the resting heart rate below its intrinsic rate.
A population bottleneck is an event corresponding to the fact that a substantial proportion of the population of a species disappears or is prevented from reproducing. There is a significantly different type of demographic bottleneck called the founder effect, which occurs when a subset of a population is, at least as far as reproduction is concerned, isolated from the main group (it does not disappear The two groups will be independent of each other).
In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals belonging to a larger population.
Answer:
Y and Z
Explanation:
Since both Y and Z has one valence electron each, they both belong to the same group (group 1) called Alkali metal group. Elements in this group have one valence electron in their outermost shell (e.g, Lithium has 3 proton and it configuration is 2, 1 and the 1 there clearly indicates its group) other examples are sodium, potassium, rubidium and francium. They all have the same properties due to one valence electron they have in common.
Answer:
because he trusted no one
Explanation:
Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.
So your answer will be Residual volume...
Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D
