The calcium that triggers muscle contraction is stored in synaptic vesicles called endoplastic reticulum. that is not the only function of the endoplastic reticulum it is also a network of a membranous tubules within the cytoplasm of a eucryotic cell continuous with the nuclear membrane.
Answer:
both the hydrophobic effect and van der Waals interactions.
Explanation:
Hydrophobic interactions refer to the interaction of non-polar groups with each other in the watery medium. Van der Waals interactions are the weak intermolecular forces formed when one molecule induces polarization in the other.
A DNA double helix has the base pair stacked on the top of one another. The adjacent base pairs are separated from each other by a distance of 3.4 angstroms. The atoms of each base pair for van der Waals interactions with each other since they are separated from each other by van der Waal contact distance.
Also, the hydrophobic surfaces of the bases make hydrophobic interactions with each other to stay away from the water. Therefore, Van der Waal interactions and hydrophobic effects both contribute to base stacking.
The correct answer is option a, that is, sedimentary rock.
There are three main kinds of rock on Earth: igneous, metamorphic, and sedimentary.
The sedimentary rock envelopes about three-quarters of the land on the surface of the Earth. However, sedimentary rock forms only about 5 percent of the top 16 kilometers of the crust of the Earth. The other 95 percent comprises of metamorphic and igneous rocks.
Sedimentary rock is malleable of the three kinds of rock. Thus, it is the quickest to erode.
I am pretty sure that planet A will move faster and i know it will have a smaller orbit then planet B
Answer:
False
Explanation:
No planet orbits in a perfect circle. They do however orbit in an elliptical orbit
