3. How can mutations benefit a species?
Answer: They can lead to speciation.
Explanation: Speciation can introduce new survival traits to a species which can lead to higher survival rate in their environment and that can lead to population growth.
Answer:
They result in specific gene variants that aid organisms in adapting to environmental changes. Beneficial mutations are required for evolution to take place. They improve an organism's chances of survival or reproduction, and as a result, they are likely to become more frequent over time.

Which of the following DO NOT describe the earth’s characteristics? *
A. Earth has an ozone layer that protect the planet from the harmful ray of the sun.
B. Oxygen contains 78% of the earth’s atmospheric gas.
C. The earth’s magnetic field serves to deflect most of the solar winds.
D. The location of the earth is far from various kind of hazards.
Answer:
B
Explanation:
The atmospheric gas contains 78% Nitrogen and 21% Oxygen. It contains more of Nitrogen than Oxygen.
Oxygen is a reactive gas so its precentage shouldn't be much. Hence, Nitrogen serve as a diluent to reduce the corrosive activity of Oxygen
Answer:
B
Explanation:
The air in Earth's atmosphere is made up of approximately 78%
nitrogen and only 21% oxygen.

NONE of these DNA fragments can be completely amplified by using these primer combinations. PCR is a molecular biology technique.
What is PCR?Polymerase chain reaction (PCR) is a technique used in molecular biology to replicate (amplify) a given fragment of DNA.
In this technique (PCR) primers sequences must be used to add nucleotides to the amplified DNA strands during DNA replication.
These nucleotide primers must be sequence complementary to the fragment of DNA desired to be amplified by PCR.
In this case, none of the DNA fragments can be fully generated by using these primers or any of their combinations.

Why is the making of sedimentary rock a physical change?
Answer:
Igneous rocks go through the physical change of erosion, where the rock is broken apart by wind and rain. The resulting sediments are deposited on the ground or ocean floor and start to be compressed into sedimentary rock.

how mutation cause colorectal cancer
Answer:
A very small portion of colorectal cancers are caused by inherited gene mutations. Many of these DNA changes and their effects on the growth of cells are now known. For example: Familial adenomatous polyposis (FAP), attenuated FAP (AFAP), and Gardner syndrome are caused by inherited changes in the APC gene.Why is the making of metamorphic rock a chemical change?
Answer:
Metamorphism occurs because some minerals are stable only under certain conditions of pressure and temperature. When pressure and temperature change, chemical reactions occur to cause the minerals in the rock to change to an assemblage that is stable at the new pressure and temperature conditions.

Please help! After 1973, American scientists began to make serious efforts to develop technologies that create
electricity from renewable resources. Do you think this step was necessary? Explain your answer.
Answer:
Yes
Explanation:
Yes, because the embargo of 1973 showed how dependent we are on just one type of fuel, so it was necessary to start looking at different ways to create energy.

Question 7(Multiple Choice Worth 4 points)
(04.03 LC)
Which process takes place in both plant and animal cells?
Conversion of solar energy
Cellular respiration
O Formation of glucose
O Photosynthesis’s
Answer:
Cellular respiration
Explanation:
Conversion of solar energy and photosynthesis require specialized equipment that animal cells just don't have. Because animal cells don't have chloroplasts, those two options are out of the question.
Animals also do not create glucose. They break down glucose and O2 into energy, H2O and CO2. Plants, on the other hand, use energy, H2O, and CO2 to create glucose and O2.
Cellular respiration is the process by which cells break down "food" into useable energy. As you can see, this happens in both plant and animal cells!

Which effect on biodiversity could start out small and grow over time to affect the larger ecosystem level? (1 point)
O large oil spill in a coastal habitat
O introduction of an invasive
species
O unexpected drought during the rainy season
O human family logging a patch of land to build a cabin and fuel their fireplace
Answer:
D. is your answer
Explanation:
this is because when you cut logs they release carbon back into the air and that can be bad over time.
A human family enters a piece of land to build a cabin and their fireplace effect on biodiversity can start small and grow over time to affect large ecosystem levels. So, the correct option is D.
What is Biodiversity?Biodiversity or biological diversity is defined as the diversity and variability of life on Earth as a measure of variation at the genetic, species and ecosystem levels. Biodiversity is explained as the diversity of all living things that are different plants, animals and microorganisms, the genetic information which they contain and the ecosystems they form.
Biodiversity is explored at three levels – genetic diversity, species diversity and ecosystem diversity. A human family enters a piece of land to build a cabin and their fireplace effect on biodiversity can start small and grow over time to affect large ecosystem levels.
So, the correct option is D.
