Plasma proteins account at least 8% of the plasma, they contribute to osmotic pressure and maintain water balance in blood and tissues, other functions includes transport and enzymatic activities. Plasma proteins include albumin, fibrinogen and globulin (alpha, beta and gamma). Globulin proteins may be used to fight infections such that gamma globulin antibodies are released by the plasma during immune response.
<span>Since alkylating agents work to prevent the cell from replicating its genetic material, the cell would most likely stop at the interphase checkpoint, which is the phase before mitosis (which consists of prophase, metaphase, anaphase, and telophase). During interphase, the cell replicates its genetic material (DNA), but this would be prohibited by alkylating agents.</span>
1. Action potential reaches the axon terminal and depolarizes it.
2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.
3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.
4. Exocytosis of acetylcholine into the synaptic cleft occurs.
5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.
6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.
the air's oxygen is partially replaced by carbon dioxide. This is because of the gas exchange that occurs so we can live.
the student should scrap off the layers until a very thin layer remains and put it back on the microscope then the student will be able to view the details of only one cell layer
