While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?
O Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
O Cells with mutations outnumber and consume normal cells that do not have mutations,
O A mutation can attack a cell's DNA and cause an autoimmune response in the cells.
+
O Mutations cause cells to become unable to divide and the cells die in masses, forming tumors.
Answer:
Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
Explanation:
Answer:
The answer is "A."
Explanation:
Cancer develops when the cells in the body are constantly dividing uncontrollably. In humans, cancer is often the result of a negative mutation genetically. The other answers are wrong and do not match the way cancer forms. So, A will be your answer.

In a histology lab a scientist observes the following features under the microscope. Which of these
observations supports cell theory?
I. Cardiac cells are joined by gap junctions and contain three nuclei.
II. Mature platelet cells do not contain a nucleus, but do contain mitochondria.
III. Spermatogonia undergoing mitosis.
IV. The bulk of tissue samples from endocrine glands contain cells as their main building blocks.
option III and IV supports cell theory.
The three essential concepts of cell theory are that: 1. cells are the fundamental building block of life; 2. living creatures consist of one or more cells; and 3. cells originate from preexisting cells.
Hint #2 2 / 4
In cell theory, the quantity of nuclei is not taken into account.
Hint #3 3 / 4
A new cell is produced during the process of cell division known as mitosis. This idea—that cells form from already-existing cells—is exact.
Hint #4 4 / 4
III and IV are both illustrations of cell theory in the actual world. Mitosis, which is the process by which preexisting cells divide to form new ones, demonstrates how cells make up living things, as does the cellular makeup of glands.

What is the substrate of enzyme 2?
What is the substrate of enzyme 3?
What is the product catalyzed by enzyme 1?
What is the starting reactant for enzyme 3? Blank 4
Answer:
anwer is down
Explanation:
A substrate is a molecule that an enzyme reacts with. The enzyme's active site, or the location where weak bonds between the two molecules can form, is loaded with a substrate. An enzyme substrate complex is formed, and the enzyme's pressures on the substrate drive it to react and become the planned reaction's result.

A group of students wants to build a ramp to move boxes from the floor up to a stage. How can the students reduce the amount of effort needed to push the boxes up the ramp?
Question 8 options:
by making the ramp as long as possible
by making the ramp’s height and length equal
by building the ramp out of a lightweight material
by covering the ramp’s surface with a soft rubber mat
If students wants to reduce the amount of effort needed to push the boxes up the ramp, it is possible by making the ramp’s height and length equal, hence option 2 is correct.
Why does it take more force to move a heavy box up a ramp?If students moves a heavy box up a ramp, there is so much friction on the undersurface of the box when going up a ramp.
To reduce the amount of effort needed to push the boxes up the ramp by making the ramp’s height and length equal, in second option by making the ramp as long as possible needs more effort.
In the fourth option, by covering the ramp’s surface with a soft rubber mat, make it harder to slide up boxes.
Therefore, by making the ramp’s height and length equal, it is easier to reduce the amount of effort.

Explanation:
3 seconds
In this kind of a situation where there exists multiple replica domain controllers that are present in the site, then the source domain controller being the one, will have to wait three seconds after issuing the first change notification. Thereafter, it then sends a change notification to the next domain controller.

The recombination frequency between linked genes A and B is 40%, between B and C is 20%, between C and D is 10%, between C and A is 20%, and between D and B is 10%. What is the sequence of the genes on the chromosome?
Answer:
ACDB (or BDCA)
Explanation:
The linked genes A and B have a greater frequency of recombination (40%) and therefore they are found furthest away on the chromosome. Conversely, the smaller distance is between D and B, which exhibit a lower frequency of recombination (10%), while C is localized at the same physical distance of both A and B (20%), so the physical map is ACDB.

5. When a hawk eats a mouse and then uses the energy from the mouse to fly,
the hawk's body converts — *
A. mechanical energy to chemical energy
B. thermal energy to mechanical energy
C. chemical energy to mechanical energy
D. mechanical energy to thermal energy
Answer:
Chemical To Mechanical
Explanation:
The Chemical energy fueled the hawk and the hawk used that energy to fly, basically like a car needs gasoline to move
The hawk body should be converted to the chemical energy to mechanical energy.
Conversion of energy:Since the hawk ate the mouse and after this it used the energy from the mouse to fly. Since food should be treated as the chemical source while the hawk flying should be treated as the mechanical source. Also, the chemical energy should fuel the hawk and the hawk should used the energy to fly where the car required gasoline for movement.
