Answer:
The community will slowly decline, or be just fine, or be better off.
Explanation:
Wolves being killed in Yellowstone showed that Yellowstone suffered, because there was nothing to kill the elk, so their population exploded and they ate everything.
If certain rats were gone in certain areas, then the community/environment would be fine, because rats eat birds and other small animals (they eat too many of them).
And if stray cats were gone then certain forests would be better off and see an increase in birds population, stray cats eat birds.

How many cellular divisions take place during meiosis?
Answer:
4
Explanation:
One division into the p1 generation, and then the p1 generation makes the p2 generation, making it 4 cellular divisions.
Answer:
2 cellular divisions
Explanation:
The reason is that there is meiosis I (reduction) and meiosis II(division). In reduction division, the chromosome number is reduced from diploid (46 chromosomes) to haploid (23 chromosomes).

DNA provides a very significant role in the formation and development of an organism.what is that role?
Answer:
The significant role that DNA provides is the organism's genetic information. It stores its information inside, and that's what makes up all the traits of the organism. All known cellular life contains DNA for this reason, and basically serves as long-term storage of information about the organism.

B) Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an example of feedback inhibition.
C) What is feedback inhibition? How is the ATP generating pathway discussed in part B an example of feedback inhibition?
Answer: B)
B) ADP can act as an allosteric activator by slowing the breakdown of fuel molecules if sufficient energy is in the cell. APT can act as an inhibitor by storing resources in more complex molecules. That is an example of feedback inhibitor because when the end product of the substrate is finished, it can bind to the allosteric site, which will result in the enzymes active site no longer being able to bind with the new substrates. And that is responsible for ATP production because That “stops” the enzyme from making more than necessary and thus wasting chemical resources.
C) Feedback inhibition is a method of metabolic control in which the need of the product of a metabolic that way acts as an inhibitor of an enzyme within that pathway. The APT generating path is an example of feedback inhibition because it controls the amount needed of the product and acts as an inhibitor of the enzyme in the anabolic pathway.

In which Colorado Rockies scenario was there more erosion? Why was there more erosion in the scenario?
Answer:
There was more erosion in the Colorado Rockies scenario where there was steady rain compared to the scenario in the same area where there was only a drizzle. There is more erosion because the steady rain increased the volume of the river more than the drizzle did. Because there was more water added to the river, the river flowed faster. The faster a river flows, the more sediments it transports or erodes.

Help!! Why do geologists radioactive/carbon dating determine absolute age? (i need this quickly!)
Absolute dating methods determine how much time has passed since rocks formed by measuring the radioactive decay of isotopes or the effects of radiation on the crystal structure of minerals. Paleomagnetism measures the ancient orientation of the Earth's magnetic field to help determine the age of rocks.

Why does cell size need to be limited?
Where does the DNA come from that is in the parent cell?
Answer:
Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.
The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.Hence the correct option is B.

Fecal coliform is an indicator of what type of disease?
Answer:
Explanation:
Some waterborne pathogenic diseases include typhoid fever, viral and bacterial gastroenteritis and hepatitis A. The presence of fecal contamination is an indicator that a potential health risk exists for individuals exposed to this water.
Answer:
Thermotolerant coliform bacteria (commonly referred as fecal coliforms) are the group most frequently used as indicators of fecal pollution because they behave in a similar way to most pathogenic bacteria in the environment, and, during treatment, they are abundant and easy to determine.
How does deforestation affect coral reefs?
Answer: When the forest cover is lost, soil washes away into rivers that flow into the oceans and, they believe, onto coral reefs. That runoff adds nutrients to the ocean water.
Explanation: Basically, when this occurs, the roots are no longer attached to the soil, letting all the nutrients get ruined in the ocean water instead of feeding plants/animals/trees.

which of the following?
O convert solar energy to chemical energy
Odigest metabolic wastes in the organelle
O produce ATP during cellular respiration
move the cell through water
Answer:
convert solar energy to chemical
Explanation:
the mitochondria is the power house of the cell
The folds greatly increase the membrane's surface area. This improves the ability of the mitochondrion to produce ATP during cellular respiration. Thus, the correct option is C.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor in the cell such as oxygen to produce large amounts of energy, to drive the bulk production of ATP (Adenosine triphosphate) in the mitochondria.
A large number of folds are present in the mitochondrial membrane to increase the capacity of the mitochondrion to synthesize ATP molecules, the inner membrane of the mitochondria is folded to form cristae in the membrane. These folds allow a much greater amount of electron transport chain (ETC) enzymes and ATP synthase to be packed into the mitochondrion membrane.
Therefore, the correct option is C.

How would you demonstrate that all cells come from preexisting cells
Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.
Explanation:
To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.
A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.
According to cell theory, the following statements are true about cells;
All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.
In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.
In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).
