What is a genetic mutation?
will give brainliest
Answer:
Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division

A. When the marble is pulled, the friction on the table is greater.
B. When the marble is pushed, the friction is greater on the sandpaper.
C. The amount of friction is about the same on both surfaces.
D. The force of gravity pulling the marble lessens the friction between the surfaces.
Answer:
B
Explanation:
because the sandpaper is rougher than the flat table.
Answer:
B
Explanation:
Sandpaper causes more friction as it has a rougher surface while in the other hand, A flat table causes less friction as the flat table has a smoother surface.

Food provides the carbon dioxide that is a product of cellular respiration.
Food provides the oxygen that is a product of cellular respiration.
Food provides the glucose that is a reactant in cellular respiration.
Food provides the energy that is a reactant in cellular respiration.
Answer:
I say food provides energy
Explanation:
Because you are gonna need energy before you play sports and then your gonna be tired after so your gonna need energy after that
Have a good day
Food provides the energy that is a reactant in cellular respiration. Therefore, option (D) is correct.
Why is food important source of energy?Nutrient-rich items are referred to as foods. Nutrients are substances that give the body the energy it needs for activity, growth, and all of its bodily activities, including breathing, digesting food, keeping warm, and they also give the body the building blocks it needs for growth and repair as well as for maintaining a strong immune system.
In general, it is made up of vital nutrients like carbs, proteins, lipids, minerals, and vitamins that are taken to support an organism's nutritional needs. These nutrients are also swallowed by an organism and used by its cells to maintain health.

Group of answer choices
the sun
the sun
the moon

The Sun is the ultimate source of energy for every process on this planet such as water cycle. Thus, the correct option is A.
What is Water cycle?The water cycle is a major biogeochemical cycle which shows the continuous movement of water within the planet Earth and the atmosphere. It is a complex system which includes many different processes such as evaporation, condensation, and precipitation. Liquid water evaporates into water vapor in the atmosphere, condenses to form clouds which then precipitates back to earth in the form of rain and snow.
The sun is the ultimate source of energy which makes the water cycle work. The sun provides energy or heat to almost everything on Earth.
Therefore, the correct option is A.

Which statement describes one role of minerals during cementation?
Minerals bind sediments together.
Compressed minerals form new rock.
Sediments dissolve and bind minerals together.
Spaces between minerals are filled with sediments.
Explanation:
Sediments dissolve and bind minerals together
Minerals bind sediments together describes one role of minerals during cementation. So, the correct option is (A).
What is Cementation?Cementation is defined as ions present in groundwater being chemically precipitated between sediment grains to form new crystalline material, where the new pore-filling minerals form "bridges" between the original sediment grains, thereby they are tied together.
It is the hardening and welding of clastic sediments, which are formed from pre-existing rock fragments by precipitation of mineral matter in pore spaces, which is the final step in the formation of a sedimentary rock in which minerals bind the sediment together.
Thus, Minerals bind sediments together describes one role of minerals during cementation. So, the correct option is (A).

Wave Rock, Australia
This concave rock formation is part of the northern side of Hyden Rock located in Hyden Wildlife Park, Western Australia. It is made of granite and estimated at 2.7 billion years old. The wave shape formed over the years by the action of running water weathering the middle faster than the top. The streaks on its face are minerals that were deposited by rainwater runoff.
--------------------------------------------------------------------------------------------------------------------------------
(02.03 MC)
While visiting Wave Rock in Australia, you observe streaks of minerals present on the landform. What natural process most likely caused the streaking?
Select one:
a. Erosion
b. Deposition
c. Oxidation
d. Weathering
Answer: It would most likely be Erosion i think.
Explanation:Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. ... Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel.
Describe a story that you think makes a good human interest story. This might be something that you’ve read/watched or it might be something that you know about from other sources. What makes it a good human interest story?
Answer:
A story that might be a good human interest story would be the vaccines for corona. Everyone these days are waiting desperately for corona to end. Talking about a vaccine might give them hope, and it would be nice to see how the scientist and doctors truly care for the people. Maybe encourage them to wear the masks until the vaccines come out?
Answer: It could be how to stay safe during this pandemic. Include what to wear ( masks, gloves, face shields, etc.), how far apart you have to stand, only go out when you need to ( grocery shopping), symptoms of this virus and other stuff like that. A lot of people go out and get coronavirus because they don't know all of this stuff.
