Answer: All
Explanation: A community is an assembly of one or more species that interacts with one another. However, in a community, the organisms would also interact with their environment.
Describe<span> the physical </span>properties of the Sun<span> (sunspot cycles, solar flares, prominences, layers of the </span>Sun<span>, coronal mass ejections, and nuclear reactions) and the impact of the </span>Sun<span> as the main source of external energy for the Earth</span>
<span>Evaporation of warm surface water increases the amount of moisture in the colder, drier air flowing immediately above the lake surface. With continued evaporation, water vapor in the cold air condenses to form ice-crystal clouds, which are transported toward shore.</span>
By the time these clouds reach the shoreline, they are filled with snowflakes too large to remain suspended in the air and consequently, they fall along the shoreline as precipitation. The intensity of lake effect snowfall can be enhanced by additional lifting due to the topographical features (hills) along the shoreline. Once the snow begins to melt, the water is either absorbed by the ground and becomes groundwater, or goes returns back to the lake as runoff.
Lake effect snow events can produce tremendous amounts of snow. One such event was the Cleveland, Ohio Veteran's Day Snowstorm from November of 1996, where local storm snowfall totals exceeded 50 inches over two to three days.
<span>A Summary of the Hydrologic Cyclebringing all the pieces together<span>
<span>Animation by: Bramer</span></span>The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transportedaround the globe until it returns to the surface as precipitation. Once the water reaches the ground, one of two processes may occur; 1) some of the water may evaporate back into the atmosphere or 2) the water may penetrate the surface and become groundwater. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.Lake effect snowfall is good example of the hydrologic cycle at work. Below is a vertical cross-section summarizing the processes of the hydrologic cycle that contribute to the production of lake effect snow. The cycle begins as cold winds (horizontal blue arrows) blow across a large lake, a phenomena that occurs frequently in the late fall and winter months around the Great Lakes.</span>
Answer:
This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.
The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''
Explanation:
Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.
The idea that all living things are composed of cells and that all cells come from other cells defines the cell theory.
Hope this helps! :)
