Answer:
A
Explanation:
Since Wolves were one of the main predators (not the ONLY one) prey started to over populate causing the vegetation population to decrease. Since the vegetation decreases so does the number of prey then as well as the number of predators.
The removal of wolves affecting the entire Yellowstone ecosystem is option "A" that is It changed the balance of many different interactions.

What is a strength in the figure?
The figure shows structures in a cell.
The figure shows stem cell differentiation.
The figure shows where mitosis occurs in the cell cycle.
The figure shows DNA replication.
Answer:
The figure shows where mitosis occurs in the cell cycle. after the interphase
Explanation:
The figure explains where mitosis occurs in the cell cycle, which is present in the third option. The cell cycle is depicted in the diagram, in which different stages are present, such as from the growth stage to the division phase.
What is the role of the cell cycle?The cell cycle is important for cell growth and division, such as the formation of gametes, the cell's growth from its original size to a larger one, the growth of body's size, and so on. The first phase of the cell cycle is the G1 phase, where the cell grows in size, and later in the S phase, DNA replication takes place. In the given image, the cell cycle is depicted with all of these stages, and after the S phase, the G2 phase takes place, and then mitosis takes place in the M phase.
Hence, the figure explains where mitosis occurs in the cell cycle, which is present in the third option.

Answer: It would be they force them out of the bloodstream.
Explanation:
Answer:
it eats or envolopes them
Explanation:
The white blood cell is attracted to the bacteria because proteins called antibodies have marked the bacteria for destruction. These antibodies are specific for disease-causing bacteria and viruses. When the white blood cell catches the bacteria it goes about "eating" it in a process called phagocytosis.
The first line of defense involves which structure(s)?
OT-cells
O skin
O blood
OB-cells
Answer:
skin
Explanation:
The skin is vital for our general health and well-being. In addition to acting as the body's first line of defense against bacteria and viruses, healthy skin also maintains fluid balance and helps regulate body temperature. She is very sensitive, she recognizes the slightest touch as well as pain.
As an outer layer that we can see and touch, the epidermis protects us from toxins, bacteria, and fluid loss. It consists of 5 sublayers of keratinocyte cells. These cells, produced in the deepest inner, basal layer, migrate to the surface of the skin. As they do so, they mature and go through a series of changes.

Explanation:
A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

What is the largest change in the energy industry's emissions in Oklahoma from 1995 to 2015?
Answer:
The largest change in the energy industry's emission in Oklahoma from 1995 to 2015 is the percentage change in the emission of nitrogen oxides with a reduction of 64.69%
Explanation:
The percentage change in emission is given as follows;
[tex]Percentage \ Change = \dfrac{New \ amount - Initial \ amount }{Initial \ amount} \times 100[/tex]
Which gives;
1) For carbon dioxide, we have;
[tex]Percentage \ Change \ in \ emission = \dfrac{41,626,050 - 43,174,445 }{43,174,445} \times 100 = -3.59 \%[/tex]
Therefore, there was a reduction of 3.59% in carbon dioxide emission between 1995 and 2015
2) For sulfur dioxide, we have;
[tex]Percentage \ Change \ in \ emission = \dfrac{60,943 - 114,317}{114,317} \times 100 = -46.69 \%[/tex]
Therefore, there was a reduction of 46.69% in sulfur dioxide emission between 1995 and 2015
3) For nitrogen oxides, we have;
[tex]Percentage \ Change \ in \ emission = \dfrac{29,381 - 83,201}{83,201} \times 100 = -64.69 \%[/tex]
Therefore, there was a reduction of 64.69% in nitrogen oxide emission between 1995 and 2015
Which shows that the largest change in the energy industry's emission in Oklahoma from 1995 to 2015 was the percentage change in the emission of nitrogen oxides.

Megan examines a liver cell and observes an organelle with many smooth-
sided channels. Which activity would identify this organelle as the Golgi
apparatus?
Digestion of macromolecules and old organelles
Detoxification of poisonous molecules within the cell
Harvesting of energy from organic molecules to make ATP
Processing and packaging of cellular materials prior to export
Answer:
Processing and packaging of cellular materials prior to export
Explanation:
Our cells contain many different organelles. Every organelle has its own function, just like every organ in our bodies.
The Golgi apparatus is one of these organelles. It can be found in most eukaryotic cells. Its purpose is to transport, modify, and package proteins and lipids before they're delivered to other parts of the body. This is the function the organelle with smooth-sided channels Megan is observing would need to perform in order to be identified as the Golgi apparatus.

The normal function of a tumor suppressor gene is A. To promote growth signals B. To cause the cell to move faster through the cell cycle C. To include programmed cell death D. To code proteins that slow or stop the cell cycle
Answer:
Explanation:
Tumor suppressor genes are genes that code proteins to slow down or stop cell division. This is because if the cells divide uncontrollable, it will lead to cancer and if tumor suppressor gene is activated it will help to slow down or stop uncontrollable cell division. It is also called anti oncogene and it repair DNA mistakes and tell when cells should die.
