A student made a model of an ecosystem inside a sealed plastic bottle. She
placed soil, rocks, water, plants, and animals inside the bottle. How is the
model unlike a natural ecosystem?
A. The model has more consumers than a natural ecosystem.
B. The model lacks the producers found in a natural ecosystem.
C. The model has more predators than a natural ecosystem.
D. The model lacks the diversity found in a natural ecosystem.
The model lacks the diversity found in a natural ecosystem.
What is a natural ecosystem?A natural ecosystem is made up of living and non living parts. Energy is cycled in the system along the food chain from one organism to another.
Thus the model that is made by the student is unlike a natural ecosystem in the sense that the model lacks the diversity found in a natural ecosystem.

How does Klinefelter syndrome caused by nondisjunction might have occurred??

The diagram below shows a type of virus called a bacteriophage. Select the name of the structure that the virus can use inside a host cell to produce new virus particles.
Answer:
It's the DNA..........
The structure that the virus can use inside a host cell to produce new virus particles is the DNA.
Bacteriophage which literally means bacteria eater is a type of virus that has the ability to infect bacteria.
Basically all bacteriophages consist of nucleic acid molecule (DNA) which is surrounded by a protein coat( the capsid head).
It also possess a tail sheath through which it transfers it's DNA into host cell.
Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis.
Therefore, the structure that the virus can use inside a host cell to produce new virus particles is the DNA.

Which statement is not an example of how the use of resources has changed?
A. More products are made from recycled materials.
B. Cars still largely rely on oil.
C. Car companies have developed hybrid cars.
D. More wind farms are present in the United States.
Answer:
B. Cars still largely rely on oil.
Explanation:
Nowadays, most countries still use transportation systems that burn fossil fuels. An example of this may be private cars that consume gasoline, which derives from fossil fuels (oil). The use of fossil fuel transportation systems increases the emission of carbon dioxide (CO2), a major greenhouse gas involved in global warming. In the near future, it is expected that fossil fuel-based vehicles can be replaced by electric cars that use energy obtained from renewable sources (e.g., solar energy, wind energy, etc).

How can you explain the difference in number of mitochondria in these types of cells?
Answer:
Organs which need alot of energy to function properly have a greater number of mitochondria
Explanation:
Mitochondria are sites for respiratory enzymes which yield energy for the cells thus skeletal muscles which need alot of energy have more mitochondria than liver and liver due to doing more activities than skin has more mitochondria than the skin.
Answer:
Skeletal muscle cells have a very high amount of mitochondria as well as liver cells because they need high amounts of energy to carry out their functions, whereas skin cells don't need high amounts of energy to function.
Why is it difficult to fossilize large animals?
Answer:
The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

What phase of mitosis is shown in the picture above?
A. Metaphase
B. Anaphase
C. Telephase
D. Prophase
The phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.
What is Mitosis?Mitosis may be defined as the type of cell division in which two daughter cells are formed from a parental cell with the exact number of chromosomes.
In metaphase, the chromosome usually lines up in one plane and forms an equatorial plate in which they are attached to the spindle fiber through their centromere.
Therefore, the phase of mitosis which is shown in the picture is Metaphase. Thus, the correct option is A.
