Answer:
The answer is the second option: Dependent variable, experimental group and control group
Explanation:
Let's list out all possible variables/groups in the option
Independent variable: This is a variable that is intentionally (directly or indirectly) altered by the one doing the experiment but is not affected by any variable/group during the course of the experiment. No Independent variable was mentioned.
Dependent variable: This is a variable that is affected by another variable and is usually the variable been tested during the course of an experiment. The dependent variable here is the effectiveness of a new nutrient supplement.
Experimental group: This is the group that is being treated during the course of an experiment. The experimental group here is the group of identical mice given the supplement.
Control group: This is a reference group that is not given any treatment during the course of an experiment. The control group here is the group of identical mice not given anything.
From the above description, it can be deduced that the parts of the experiment described in the scenario in the question is dependent variable, experimental group and control group.

What type of consumer do you think this coyote is? Can you tell from the photo that the coyote is not an omnivore?
Answer:
Carnivore.
Explanation:
Based on the picture alone, the coyote is eating meat, which would make it a carnivore.
Cayote is a tertiary consumer.
The photo alone cannot tell us cayote is not an omnivore.
Tertiary consumers are organisms on the fourth trophic level of a food chain. Most tertiary consumers like the cayote are omnivores.
Omnivores feed on both plants and animals. The cayote feeds not only on other animals like ducks, squirrels, fish, grasshoppers, but also feed on young plants and berries form plants.
The photo only shows us a cayote feeding on just one source of its diet which is a smaller animal. It cannot tell us that the cayote is not an omnivore because it doesn't show us the entire food web of the cayote in its ecosystem.
In conclusion, the cayote is a tertiary consumer. You cannot tell the cayote is not an omnivore from the photo.

Which phrase describes foliated rocks?
DO NOT CHECK ALL THAT APPLY
tend to break in half
grains arranged randomly
tend to split apart along bands
grains arranged in increasing size
Answer:
tend to split apart along bands
Explanation:
Foliated rocks are metamorphic rocks that are formed due to high pressure and heat leads to the layered or banded appearance of the rocks.
Due to the layered or banded appearance of the rocks, foliated rocks tend to split apart along bands that are aligned parallel to the minerals in the rocks. Example of foliated rocks: Slate, that split into thin sheets along bands .
Hence, the correct answer is "tend to split apart along bands ".

beeties of the same species us exposed to the new pesticide for a 10-week period. A separate population of the same species of beetle is exposed to
the same amount of the current pesticide for a 10-week period. The data collected is sent to an independent research company to verify the results,
Which statement BEST explains how an independent research company verifies data to ensure unbiased results,
The company sends out the data to another researcher to investigate
The company tests many types of pesticides and draws its own conclusions
The company performs the same investigation and compares the results
The company compares the data given to similar investigations
Answer:the company will perform the same investigation and compare the results to the manufacturers
Explanation:
Just did the quiz
The independent research company performs the same investigation and compares the results.
Scientific experiments must be reproducible. For the results of a scientific experiment to be reliable, other scientists must be able to carry out the same experiment and obtain similar results as reported. This is what it means for results to be reproducible.
Hence, for the independent company to ensure that the results are unbiased, the company performs the same investigation and compares the results.

Explanation:
is osmosis passive or active transport
Answer:
Passive Transport
Explanation:
Osmosis does not require ATP so it is a passive transport. Osmosis is a form of passive transport. Water molecules are small enough to move freely across the plasma membrane without the use of ATP
message me btw : )
Answer: Osmosis is passive transport.
Explanation: Water moves from areas where solutes are less concentrated to areas where they are more concentrated.
Why can water have no net charge but have slight
charges in different parts of the molecule?
Water molecule is made up of one atom of oxygen and two atoms of hydrogen. The water is a polar compound and has slight charges due to differences in the charges.
Water molecule is composed of hydrogen and oxygen and is inorganic transparent liquid. The hydrogen and oxygen in a water molecule are linked by covalent bonds.
The oxygen is electronegative and attracts electrons. There is however no overall charge on the water molecule, but atoms of the compound have slight charges.
The unequal sharing of electrons between hydrogen and oxygen can give them slight positive and negative charges, respectively.
Thus, there are slight charges present on oxygen and hydrogen.

Students in a biology class were discussing outbreaks of food-borne illness. Modern practices of refrigeration are aimed at curbing (limiting) these bacteria. They wanted to know exactly what happened to bacterial colony growth at varying temperatures. The teacher explained that scientists study bacteria in the laboratory by counting colonies that grow on plates filled with agar, which is a nutrient substance. “Design” an appropriate experiment that would test the effect of temperature on bacterial growth. You would have a period of 5 days to conduct an experiment.
Answer:
I know this isn't a big help answer, but you could use it as a start. You could say something like "I tested it in multiple different temps. including .... (any temps. you want) Then say how all of thoose different temps. changed the bacteria." I hope it helped! :)
Explanation:
Most of the foodborne diseases are caused by those bacteria that can grow well and infect food at normal temperatures, and their population can be controlled by lowering the temperature or raising the temperature too high, which can degrade their cell walls.
What is the effect of temperature on the bacteria?There are numerous bacteria that can infect food and cause foodborne disease when consumed by humans, resulting in diarrhea, stomach aches, and other symptoms. Because most of these bacteria grow at room temperature, keeping food at that temperature degrades it faster, so foods are kept and stored in the refrigerator. This low temperature keeps the cellular activity of bacteria low; as a result, the bacteria cannot produce toxins or grow their population.
Due to this, the refrigerator stores the food for a longer time. Different strains can be kept and stored at different temperatures on an agar plate, but a strain present at a low temperature will produce far fewer colonies than one present at a room temperature. Further the growth depends upon the types of bacteria.
Hence, by refrigerating the food, cellular activity is seized and controlled.

Many villages also grow into urban/semi urban areas. This is a sign of economic growth but with the cost of environmental damage. This damages 3 things - air, water, and land. Due to urbanization, many roads are constructed. It passes through the natural habitats of other wild animals. These roadways split their habitat, and cause a reduction in their number.
The urban sprawl causes set up many factories, the use of vehicles which does air pollution. People are more prone to use vehicles which are responsible for air pollution.

D.slower growth
Answer:
This process is akin to searching for the proverbial needle in a haystack, because many of the mutations present in these cells have little to nothing
Explanation:
During mitosis, normal cells undergo checkpoints that monitor the fidelity of the processes that occur during the cell cycle. Uncontrolled cell growth refers to the breakdown of these regulatory checkpoint mechanisms.
In the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).Apoptosis refers to the programmed cell death that prevents the uncontrolled growth of cancer cells.In cancer cells, genes that control apoptosis during the cell cycle suffer mutations, thereby leading to uncontrolled cell growth.In conclusion, in the cell cycle of typical cancer cells, mutations most like cause UNCONTROLLED GROWTH (Option A).
