Answer:
The correct answer is option - C. low power objective.
Explanation:
In microscopes, low power objectives have a wide field of view and use to study the many smaller specimens or large specimens. 10X is the power of the low objective.
To study the depth of the field the lower objective rotated and aligned on the place over the specimen. When you move to high power objective the field of view gets close in and only can study the smaller specimen or small section of a large specimen.
Thus, the correct answer is option - C. low power objectives.
The theory of evolution provides a number of insights:
-it tells us how the species are related
-it tells us how the species and populations react to the changes in their environment
With this knowledge, the scientists can predict how the species will react to the potential changes and support the positive changes (provide a good environment for the animals for example) <span />
Answer:
b. active transport
Explanation:
Active transport -
It is the movement of the molecules across the membrane via a region of lower concentration towards the region of higher concentration , and in some cases , the flow is independent of the concentration .Its is known as active transport .
This process needs some amount of energy in the form of cellular energy .
Hence , the correct term for the given statement is active transport .
Answer:
Most TP53 mutations change single amino acids in the p53 protein, which leads to the production of an altered version of the protein that cannot control cell proliferation and is unable to trigger apoptosis in cells with mutated or damaged DNA. As a result, DNA damage can accumulate in cells
