Studies have shown that children are especially vulnerable to the effects of ultraviolet (UV) radiation. Tanning beds expose the skin to nearly ten times as much UV radiation as natural sunlight. With that knowledge, a law was passed in some states to prevent individuals under the age of 18 from using tanning beds. Which statement best explains why UV radiation is so harmful?
a) It can increase harmful DNA mutations in cells.
b) Diseases are all caused by exposure to environmental factors.
c) Homeostasis in an organism is increased by the presence of UV radiation.
d)UV Radiation decreases the likelihood that mutations will occur.
Answers
Hello there!!
The answer, I think, would be A.
UV radiation can create problems in the correctness of cell replication, which can result in mutated cells.
I hope this answers your question!
Tanning beds can increase harmful DNA mutations in cells. So, the correct option is A.
What are Tanning beds?In order to tan individuals, a tanning bed emits UV radiation (make their skin darker). If someone spends too much time in the tanning bed, it can also burn their skin, much like the sun. Many types of tanning beds exist. Using tanning beds can lead to more damaging DNA alterations in cells.
Special fluorescent lights (16–32 per tanning bed) that produce both visible and UV light are used in tanning beds. They employ a ballast system, like all fluorescent lights, to keep the amount of electricity going to each lamp to a maximum of 100 watts per lamp. A specific acrylic, or clear shield, is used over the bulbs in tanning beds.
Therefore, the correct option is A.

A drought is a period of unusually low
rainfall. A farmer notices that a well on the farm stops providing water
during a drought. A nearby lake also
has less water in it than usual. Write a
couple of sentences that explains
what has happened to the water table
in the area to cause these results.
Answers
In the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.
What is drought?Drought may be defined as a brief period of abnormally dry weather sufficiently prolonged for the lack of water to cause a serious hydrologic imbalance in the affected area.
During severe droughts, people depend heavily on groundwater—the water held underground in aquifers. During these periods, the rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth of water in wells gradually increases.
Therefore, in the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.

explain the differences between the particles of a pure substance and the particles of a mechanical mixture
Answers
Answer:
A substance is pure if it is a single substance, and it is made up of only one type of particle. If there is more than one substance, and therefore more than one type of particle, it is a mechanical mixture, the particles can be easily distinguished, due to their non-uniform composition. The composition of a mechanical mixture is variable and their components may be separated by physical or mechanical means because they are not chemically bound.
Explanation:
A pure substance is one that has a composition and characteristic properties that do not change, whatever the physical conditions in which it is found; that is, the physical transformations do not affect it. In other words, pure substances will be made up of particles that are identical to each other. Mechanical mixture are the result of the physical union of two or more substances which are called components, these can be elements or compounds, whose particles do not mix uniformly. The components of the mixtures have different properties, such as the state of aggregation, the density or the solubility. These properties allow substances to be identified and facilitate the separation of the components of a mixture, that is, through physical or mechanical processes we can isolate and obtain the components that make up the mechanical mixtures.

When resistant bacteria multiply, what do they pass on to the next generation?
Answers
Answer:
Antibiotic use promotes development of antibiotic-resistant bacteria. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant germs may be left to grow and multiply. Repeated and improper uses of antibiotics are primary causes of the increase in drug-resistant bacteria.
The resistant bacteria can reproduce rapidly because their competition (the non-resistant bacteria) has been destroyed by the antibiotic. When the resistant bacteria reproduce, they produce genetically-identical copies. These copies will all be resistant to the antibiotics.
