A microscope is a device that scientists use to see objects that are too small to be seen by the eye. They can be used to observe cells inside an organism.
Answer:
a microscope is a laboratory instrument that is used to see little organisms or organisms that cannot be seen with bare eyes
Answer:C proteins
Explanation:
Chlorofluorocarbons
DDT
Chlorofluorocarbon (CFC) is used as the aerosol propellant. An aerosol is a suspension in the gaseous form of solid or liquid particles. When these compounds reach the stratosphere, UV light affects them and they release chlorine atoms. Chlorine atoms are capable of breaking down ozone molecules. With fewer ozone molecules, the ozone layer becomes thinner and harmful UV light passes through it.
The correct answer is B. Chlorofluorocarbons.
I took the test in K12 so I am 100% percent positive
Food chains is a path that energy flows in an ecosystem and it usually indicate the level of eating within an ecosystem.
Producers are organism that usually absorb the sun’s energy and thereby convert the energy into food for growth and to make fruits or flowers. Examples include plants, algea
Primary Consumers: they are organism that only eat plants and can also be refers to as herbivores. However, example of herbivores includes grasshopper and bees.
Secondary consumers: they are organisms that eat both producers and primary consumers. They can be refers to as omnivores. Example includes beetle and wasp.
Level of Food chain
Plant---------Grasshopper---------Beetle
A food chain consisting of a producer, primary consumer, and secondary consumer includes grass as the producer, rabbits as the primary consumer, and foxes as the secondary consumer.
An example of a food chain that consists only of a producer, primary consumer, and secondary consumer is as follows:
In this example, the grass is the producer as it produces its own food through photosynthesis. The rabbit is the primary consumer as it feeds on the grass. The fox is the secondary consumer as it preys on the rabbit.

(Choice A)
Chloroplast
(Choice B)
Vacuole
(Choice C)
Nucleus
(Choice D)
Mitochondria
Determining which cell structure is represented by 'C' isn't possible without a diagram. However, the listed structures include the Nucleus, Chloroplast among others, with each playing a significant role in cell functionality.
Without the specific diagram, it's difficult to accurately determine which structure is represented by the letter C. However, given the options, the four choices, A) Chloroplast, B) Vacuole, C) Nucleus, and D) Mitochondria, are all essential components to a cell's functionality. The Nucleus acts as the control center of the cell, containing DNA and regulating gene expression. The Chloroplast, on the other hand, is unique to plant cells and is the site of photosynthesis where sunlight is converted into energy for the cell.
