<span>The cytoskeleton is a
structure found in the cytoplasm that is composed of a web of proteins. It is a
network composed of protein microfilaments, intermediate
filaments, and microtubules. They can be found in all living organisms and are
responsible for giving them their distinct cell shapes and coherence.
Aside from
providing the cell shape, the cytoskeleton is also responsible for cell
movement, organelle movement, and cell division.</span>
<span>It plays a crucial role in
cell division because they provide the movement of chromosomes to the daughter
nucleus. The absence of these protein filaments would result to different
abnormalities and diseases in the genes. </span>
Question 5:
A scientific theory should not be regarded as reliable (false).
Scientific theories are reliable.
Question 6:
It is best to use a line graph to show change over time.
The correct answer is - C and D.
The principle of original horizontality means that the rock layers have been order by age, with the layers at the top being the youngest, while the layers at the bottom being the oldest.
In this picture it is little hard to tell which rocks belong to the same layer from first look because there are multiple twists and turns, an uneven surface, caused by pressure on the crust.
By carefully examining the image though, we can trace the layers more properly and see which ones are younger, which older, and which have the same relative age. In this case, we can see that the markings C and D are actually on the same layer of rocks, thus being a good indication that they have the same relative age.
Answer:
Looking for light
Explanation:
Since plants require sunlight in order to produce light, they need to be exposed to it. Now, since there are other plants attempting to do the same they have to grow higher so they don't get put in the others shadow and possibly die due to lack of sunlight.
