Where and how is a star born?
Answer:
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

The community requested assurance that the process would be safe for both the community and the environment. Which biology-related professionals might be hired to help this company meet that goal?
Answer:c
Explanation:
The company might hire a toxicologist, an ecologist, and/or an environmental scientist to help assess the potential impact of the waste management process on the community and the environment.
Who is a toxicologist?Toxicologist is a professional who specializes in the study of the harmful effects of chemicals on living organisms and the environment. They use their knowledge of chemistry, biology, and medicine to evaluate the potential dangers of different chemicals and to develop safe handling and disposal procedures.
They may work in a variety of settings, including government agencies, research institutions, and private industry. In the context of the factory and waste management, a toxicologist could be hired to ensure that the waste produced by the factory is safe for the community and the environment, and that the disposal methods used are in compliance with relevant regulations.

A. It becomes brittle.
B. It shrinks.
C. It darkens in color.
D. It becomes stronger.
Answer: A
Explanation: just took the test :)
The plastic that absorbs energy from sunlight becomes shrink. The correct option is B.
What are harmful effects of plastic?Endocrine disrupting substances (EDCs) are among them; they have been connected to a number of diseases such as infertility, obesity, diabetes, prostate cancer, and breast cancer.
In addition to these problems, chemicals have also been related to issues of neurodevelopment, growth, and reproduction.
Chlorinated plastic has the potential to leak dangerous chemicals into the soil around it. These chemicals can then seep into nearby water sources, including groundwater, and the ecosystem.
The species that consume the water may experience a variety of potentially dangerous impacts as a result.
The plastic is exposed to sunlight, which oxidises it and converts the polymers into oligomers, extremely soluble organic molecules.
Plastic breaks down into smaller molecules and absorbs UV radiation from the sun, thus how quickly it decomposes depends on how much of it is exposed to sunshine. This process is known as photodegradation in science.
Thus, the correct option is B.

how do infrared waves, uv waves,and microwaves affect us
Answer:
Here is your answer
Explanation:
Infrared radiation has a longer wavelength and lower frequency than visible light. Too much exposure can damage your eyes and skin. On a global scale, trapped infrared radiation contributes to global warming.
UV rays, either from the sun or from artificial sources like tanning beds, can cause sunburn. Exposure to UV rays can cause premature aging of the skin and signs of sun damage such as wrinkles, leathery skin, liver spots, actinic keratosis, and solar elastosis. UV rays can also cause eye problems.
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn. But these types of injuries – burns and cataracts – can only be caused by exposure to large amounts of microwave radiation.

Carmen conducted an experiment to determine if listening to different types of music would affect a person’s pulse. Her hypothesis was that pulse rate would change with different types of music. Each person listened to seven different selections of music for 30 seconds each. Each person’s pulse was taken before the music and then after each 30-second interval of music. The pulses were taken again after the music selections were completed. Based on her experiment, Carmen concluded that a person’s pulse rate changed when the person listened to different types of music. Which component is missing from Carmen’s experiment?

Which is one event that may lead to Primary succession? clear-cutting climate change volcanic eruption introduced species
Answer:
Primary Succession is when an uninhabited area becomes an ecosystem, and Secondary secession is when an ecosystem is destroyed an Independent factor, like a fire, a hurricane, stuff like that.
Explanation:
Clear-cutting climate change would be an example of Secondary Secession, and volcanic eruption introduced species would be an example of Primary Secession.
Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time.
The event that may lead to Primary succession is: volcanic eruption
What are the three causes of primary succession?The main causes of ecological succession include the biotic and climatic factors that can destroy the populations of an area. Wind, fire, soil erosion and natural disasters include the climatic factors.
What organisms come first after a volcanic eruption then what happens?Lava from a volcanic eruption hardens into bare rock. Primary succession begins with soil formation. The first stage of succession involves pioneer species. In primary succession, pioneer plants are those that can grow without soil, such as lichens.

Increasing the rate of an impulse is the function of the_________.
A myelin sheath
B. axon terminals
C. cell body
D. axon
Answer:
Myelin sheath
Explanation:
Increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.
What is Impulse?The Impulse may be characterized as an electrical signal that can be transmitted along a nerve fiber in response to an external or internal stimulus.
The Myelin sheath increases the rate of nerve impulses. This is because it insulates the part of axons and reduces the chances of any disturbance in between due to the assemblage of voltage-gated sodium channels.
Therefore, increasing the rate of an impulse is the function of the myelin sheath. Thus, the correct option is A.
