The graph shows the percentages of different types of lightbulbs shipped to
consumers in North America over three years.
Answers
Fluorescent light bulbs made up the majority of the lightbulbs supplied to households in North America during the course of three years, as shown on the graph.
How does fluorescent refer to in terms of lighting?Fluorescent lamps, often referred as fluorescent tubes, are low-pressure mercury-vapor gas discharge lamps that emit visible light by fluorescence. Mercury vapor is excited by a current flow in the gas to produce short-wave ultraviolet light, which illuminates a phosphor covering inside the lamp.
What causes something to fluoresce?An object's ability to absorb light at one wavelengths and then reemit it at a different wavelength is known as fluorescence. A molecule is referred to as a chromophore if it fluoresces, or absorbs about one wavelength then emits it at another.

How do living organisms return carbon to the atmosphere in the carbon cycle
Answers
Answer:
Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis
Living organisms return carbon to the atmosphere in the carbon cycle by two process namely respiration and combustion. Carbon dioxide is absorbed by producers to make glucose in photosynthesis.
What is photosynthesis?
A photosynthesis is a biochemical process which occurs in plants, algae, and bacteria, when they are exposed to sunlight. During photosynthesis, water and carbon dioxide join to form sugars and give off oxygen.
Respiration is defined as the inhaling of oxygen and the exhaling of carbon dioxide and combustion is defined as the process in which a substance burns in the presence of Oxygen, produce off heat and light in the process.

1. What are the different properties of light that apply to the image formation of
optical devices such as mirrors and lenses?
Answers
Answer:
Optical instruments are based on optics. They use mirrors and lenses to reflect and refract light and form images. The light microscope and telescope use convex lenses and mirrors to make enlarged images of very tiny or distant objects. A camera uses a convex lens to make a reduced image of an object.
The property of light that is important to the image formation in mirrors is reflection. The property of light that is important in the formation of an image by lenses is refraction.
Light refers more specifically to the portion of the electromagnetic spectrum that is perceivable with the optical eyes. There are several properties of light such as reflection, refraction, diffraction, interference, etc.

What is the difference between flu viruses and the measles virus?
Answers
Answer:Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.
Explanation:
Explanation:
Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.
By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

What are ethical concerns in using animals for research?
Select all that apply.
Animals cannot consent to being used in experiments.
Animals are ideal biological models for experiments
Many animals can be studied at one time.
Some animals may have adverse reactions.
Answers
Answer: Animals cannot consent to being used in experiments.
Explanation:
Animals are not suitable options for the biological research as they are getting extinct and their population size is getting decreased. Option A is correct.
What are extinct species ?These are the species that are getting diminished from planet because of certain factors such as loss of habitat and many other crucial factors that affecting their growth.
Animals can not be used in the biological research as they are not able to speak the language which is understood by humans and ideally it is not right to do dissection over living beings.
Animals earlier were definitely considered for the experiment but the awareness of ethics and sensitivity of the issues is bringing down the ban on the animal crimes along with the lab research.
Ethical concerns are as well that without God's permission it is not right to harm the living beings.
Therefore, option B is correct.
