Colder temperatures that last for a short period of time such as 3-4 days.
Answer: Many are DECIDUOUS TREES that lose their leaves in fall, but the broad-leaved trees of a tropical rain forest are evergreen. The mass of leaves of adjacent trees form a CANOPY.
Explanation: I hope this helps, I am stuck on the same question too.
Explanation:
In all living system we can always find basic elements carbon, oxygen, nitrogen and hydrogen, carbon is the basic building unit contained in living matter. The percentage of carbon in the mass of living matter is 19.0% oxygen and hydrogen are present in almost all organic compound which creates living organisms.
Numerous antiepileptic medications, such phenytoin, have been designed to block voltage-gated sodium channels (VGSC) in neuronal membrane. In addition, multiple toxins and pharmacological modulators work by attaching to various biophysical states of the VGSC to cause their effects. Depending on how modulatory agents act, some VGSC states are stabilized or destabilized, altering the channel's biophysical properties. The first anticonvulsant to successfully treat epileptic disorders without causing undesirable side effects such as brain drowsiness was phenytoin.
Phenytoin has been indicated to block high-frequency neuronal activity potentials from the inner vestibule of the pore, as demonstrated by electrophysiological research and site-directed mutation.
Frequency and voltage both affect phenytoin binding.
There are theories that phenytoin interferes with the late sodium current that sustains depolarizations in epilepsy by blocking non-inactivated channels.

The answer would be True
Alcohol can be easily absorbed by the stomach without digestion, which makes the onset it needs to start making the effect is really fast. Around 25% of alcohol will be absorbed by stomach while the rest absorbed in the small intestine. The initial effect of alcohol will impair the ability to make a decision, decrease visual function and altering mood.
