Answers

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

Answers

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.

how do infrared waves, uv waves,and microwaves affect us

Answers

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.

Which sentence describes what happens to plastic that absorbs energy from

D. It becomes stronger.

Answers

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.
