Answer:
I am not 100% sure but my best guess would be the object is moving backwards/falling.
Explanation:
The graph shows the position of the object going from almost 9.0 to below zero. There are many situations that could fit this. Such as, something going above and below sea level. OR something moving in front and behind a certain point. My best guess would be moving backward towards an object OR falling from a certain point.
All controlled experiments would have only one variable. If there were more than one variable the outcome of your experiment could be for multiple reasons and thus you would not be able to test whether your specific hypothesis was valid.
Answer:
Active transport of calcium into the sarcoplasmic reticulum.
Explanation:
- The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+)
- In response to an action potential traveling along the t tubule, voltage-sensitive proteins change shape, opening calcium channels in the adjacent terminal cisterns of the sarcoplasmic reticulum.
The role of a pioneer species in primary succession is to normalize the habitat by making the topsoil more stable and fertile. Explanation; -In primary succession pioneer species like lichen, algae and fungi as well as other abiotic factors like wind and water start to normalize the habitat.
