A(n) Transverse wave best describes a wave whose direction of travel is perpendicular to the displacement of the medium.
Answer:
E. Enzyme cleaves PIP2, forming DAG and IP3.
D. IP3 binds to a ligand-gated ion channel in the ER membrane.
A. Calcium ions flow through the ligand-gated ion channel.
C. Calcium ion concentration increases in the cytosol.
B. Calcium ions activate a protein, leading to a cellular response.
Explanation:
The enzyme phospholipase C which cleaves PIP2 into DAG and IP3 Is activated by the G protein once the histamine signaling molecule is received. IP3 moves to the cytosol to bond to IP3 gated calcium channel in the Endoplasmic reticulum membrane allowing for influx of Ca++ from the Endoplasmic reticulum membrane to the cytosol prompting a cellular response. The histamine's signal transduction pathway allows for amplification and regulatation of a signal at different points
Answer:
recreational - enjoyment i.e. weed, alcohol (legal)
shrooms, lsd (illegal)
liver or lung failure
stimulant- helps asthma and other things example. dexedrine
the effects of taking stimulants is loss of appetite, increased heart rate, elevated blood pressure and body temperature, interrupted sleep patterns, panic, hallucinations, and irritability.
also a drug is a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body.
<span>The smallest unit of geologic time is epoch.</span>
There are many factors that can contribute to this, for instance:
- Increase in food
- Decrease in predators
- Decrease in competition
All of these would allow a species to strive and grow.
Hope this helps!
