Answer:
Anaphase
Explanation:
After anaphase, a cleavage furrow forms in the equatorial cortex in typical animal mitosis. To divide the two daughter cells, this furrow then progresses inwards.
The sister chromatids differentiate from each other in anaphase and are pulled toward opposite ends of the cell. The "glue" of protein that binds together the sister chromatids is broken down, causing them to separate. Each one now has a chromosome of its own.
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc.
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
The one challenge for biology right now is:
Biologists are always seeking better tools for imaging the body and the
brain. Many mysteries remain in the catalog of human genes involving exactly how genes work in processes of activation and inhibition.
Answer:
Human activities can affect climate change because of just how much waste we produce. One huge example is our burning problem, which slowly strips away at the ozone layer that protects animals from heat and melting snow. Because of the ozone layer, the arctic has been protected for many years but now it's slowly disappearing, melting ice and killing animals who have not learned to survive in such hot weather. Another example is when humans cut down too many trees to sustain the environment; it often causes a massive lack in natural oxygen and unroots many homes of small critters and worms. In conclusion, humans can heavily affect climate change because of our ignorance and how we refuse to learn for the future.
