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).
Answer:
B is not correct. I know cause I took the test here are the correct answers!

Explanation:
A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis. A food chain ends with a consumer, which is an animal that eats a plant or another animal.
Green plants are producers
They are the first link in all food chains
Plant cells contain chlorophyll and can photosynthesise
Photosynthesis produces glucose and oxygen
Animals are consumers
If they eat plants, they are the first-order consumers or herbivores
The chemical energy in the green plants is transferred to the animal when it eats the plant .

Which of these is NOT a reason to take photographs of a crime scene?
A to document the relative locations and positions of evidence
B some evidence can not be collected
C some evidence does not last / is temporary
D once evidence is used in court it is thrown away, and photographs allow CSI to study evidence years later
the answer would be d hope thos helps
The one that is not a reason to take photographs of a crime scene is once evidence is used in court it is thrown away, and photographs allow CSI to study evidence years later. The correct option is d.
What is an evidence?They photograph and physically measure the scene, identify and collect forensic evidence, and keep the evidence in the proper chain of custody.
Fingerprints, footprints, blood and other bodily fluids, hairs, fibers, and fire debris are all gathered by crime scene investigators all are included.
While the most obvious goal of crime scene photography is to create a visual record of the crime scene and all of its relevant features, the best example of photography's role is the presentation of a logical story.
The one reason not to photograph a crime scene is that the evidence is used in court, it is discarded, and photographs allow CSI to study evidence years later.
Thus, the correct option is d.

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.

Homer Simpson goes to his job every day at the Springfield nuclear
power plant. His job as a safety inspector helps keep people and the
environment safe from the possible hazards of nuclear power. Most of the
hazards from his job involve monitoring which of the following?*
A.Uranium-235 and waste containment
B.Water levels and temperature in local lakes
C. Carbon dioxide and other greenhouse gas emissions
Answer: I've never watched Simpsons, but I saw half an episode once on tv where he totally blew up the entire company or something. But I think they said his job was as a technical guy, but he kept falling asleep, and didn't know how to do anything, and that's why he couldn't stop the explosion, or something.
I hope this helps. I'm thinking it doesn't, though.
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.

What are some of the roles of proteins in the human body?
Which pair is correct?
a. G2 phase, preparation for mitosis
b. G1 phase, DNA replication
c. M phase, cell growth
d. S phase, cell division
A pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next.
In the G1 phase of the cell cycle, the cell grows in size and synthesizes mRNA as well as proteins which are required for DNA synthesis.
M-phase governs the nuclear division (Karyokinesis), and cytoplasm division ( cytokinesis).
S-phase is known to double the amount of genetic content within the cell.
Therefore, a pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.

Are the oldest rock on the highest or lowest stratum?
Answer:
The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top.
Explanation:
The principle of superposition states that in an undeformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it (Figures 1 and 2). Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.
☁️ Answer ☁️
Lowest.
the lowest stratum tend to have the slowest-moving creatures; above them are faster ones. Evolutionary scientists declare these lowest strata are many millions of years old (570 million for the oldest, the Cambrian), and the topmost to be the most recent.

Since pesticides run off from
several farms and fields can make its
way to are waterways such as rivers,
lakes, and oceans, what type of pollutant
are they considered to be?
I know this is supposed to be a question but the answer is a Non-Point solution.
Answer:
It can also clog the gills of fish or smother fish larvae. In addition, other pollutants like fertilizers, pesticides, and heavy metals are often attached to the soil particles and wash into the water bodies, causing algal blooms and depleted oxygen, which is deadly to most aquatic life.Nutrients like nitrogen and phosphorus are essential for growing crops, but they can also trigger algal growth in rivers, lakes and bays. Agricultural runoff flows into the lakes and rivers that hundreds of towns draw their water from.Runoff picks up fertilizer, oil, pesticides, dirt, bacteria and other pollutants as it makes its way through storm drains and ditches - untreated - to our streams, rivers, lakes and the ocean. Reducing runoff can help prevent water pollution, reduce flooding, and protect our precious drinking water resources.
Explanation:
Stormwater runoff can also wash sediment, nutrients or other pollutants into water sources. Increased sediment, nutrients and other pollutants can diminish water quality, threaten drinking water sources, and complicate water treatment processes.
