Answer:
Cancer is a disease that involves uncontrolled cell division caused by a genetic mutation. It can occur in almost any region in the body. So, cancer is essentially uncontrolled mitosis of specialized cells
Explanation:
It can occur in almost any region in the body. So, cancer is essentially uncontrolled mitosis of specialized cells. The correct options are b and c respectively.
What is cancer?Cancer is a medical condition in which cells in one portion of the body expand and multiply inconsolably.
Cancerous cells have the ability to invade and destroy healthy tissue, including organs. Cancer can start in one part of the body and spread to other parts. This is referred to as metastasis.
Cancer is caused by changes in genes, which are the basic physical units of inheritance. Genes are organized in chromosomes, which are long strands of tightly packed DNA.
Cancer is a genetic disease, which means that it is caused by changes in genes that regulate how our cells function, particularly how they grow and divide mitotically.
Thus, the correct options are b and c respectively.

Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
a scientific theory? Do you think it should be a scientific law? Explain your response.
Yes, Because that theory can easily be backed up with facts and evidence making it a scientific law
Answer:
Cell theory meets the definition of a theory because it has been tested over a long period of time, and scientists have plenty of evidence to support this theory. However, it doesn’t seem to meet the criterion of a scientific law. Scientists only know about life on this planet, so the theory may not be universal if life is found on other planets. In addition, scientists don’t have much data on the earliest forms of life on Earth.

which statement accurately names and describes the function of the organelle labeled B?
Answer:
A.
Explanation:
The mitochondrion receives energy produced by organelle A.
The statement that correctly describes the function organelle B is ; ( A )
A mitochondrion produces energy from food to power cellular processes
From the diagram the organelle labelled A receives/absorbs light energy from the sun and this energy is transferred to the Mitochondrion ( organelle labelled B ).
The energy received by mitochondrion is used by the organelle to breakdown down consumed food to produce the energy ( ATP ) which powers the every other cell.
Hence we can conclude that The statement that correctly describes the function organelle B is ; A mitochondrion produces energy from food to power cellular processes

A student pushes a television cart to the left with a constant force of 100 N. The force of friction between the cart and the floor pushes back to the right with a force of 75 N. If the cart was initially at rest, how will it move as the constant force is applied?
Answer:
Explanation:
As you can see in the badly drawn picture below, the force pushing to the left is 100N while the opposing force pushing the right is 75N. These forces are subtracted from one another, which would leave us with a total force of 25N (100N - 75N = 25N) pushing to the left. Since the cart is initially at rest, this means that there is no additional force being applied left or right of the cart. Therefore, with the 25N of force, the cart would move at a constant speed to the left.
If the cart is at rest, it will move to the left at a constant speed.
We can arrive at this answer because:
The cart is at rest when no force is applied to it.When the student pushes the cart to the left with a force of 100N, the cart will be forced out of rest if this force is greater than the drag force, which pushes the cart in the opposite direction.As we can see, the force that pushes the cart in the opposite direction is equal to 75N, and therefore, we can say that the cart will move to the left.However, the movement of the cart will not be done with a force of 100N, as 75N of this force will be canceled out, due to the force that pushes the cart in the opposite direction. In this case, the cart will move with a force of 25N.

Answer:
Constructing a safe passage for fish seems like a way to avoid the problem, and in theory, it could reduce the risk of injury or death to fish. But my research shows that building fish passages can be difficult, and their effectiveness is mixed. Also, different passages may need to be built for different species, which is time-consuming and costly.
Working with engineers to design a dam with these risks in mind seems to be the ideal solution, because we can design the dam with the native species in mind. But the biodiversity issues related to hydroelectric dams is a fairly new concern, so we may not have a lot of past evidence to reference. We may have to use the trial and error method, which seems risky.

"If liquids are heated to a certain temperature and germs die, then the liquids will be less likely to cause sickness when consumed, because reducing germs is a way to prevent disease.”
How was this new hypothesis most likely inspired by the work of Joseph Lister?
Lister had taught that boiling water makes it safer to drink.
Lister’s experiments showed that reducing germs during surgery prevented infection.
Lister’s experiments showed that germs can cause infection no matter how they enter the body.
