Genetic mutations introduce new gene forms in a population. For instance, the mutation that affects
hemoglobin alters the shape of the red blood cell and makes it sickle-shaped. Which statement
below would explain why the sickle-cell mutation has spread through the gene pool?
A. There is a selective advantage to having Sickle Cell Anemia.
B. This kind of mutation demonstrates a common ancestor.
C. The sickle cell mutation has no benefit.
D. Sickle cell anemia increases the risk of death.
Answer:
B- this kind of mutation demonstrates a common ancestor.
Explanation:
in order to have sickle cell anemia you need to have both recessive alleles from both parents, this recessive allele has to be continuous passed down from generation to generation on both sides, which shows a common ancestor from long ago

Explain what is likely to happen to a water molecules entering area A in the process of photosynthesis
Answer: The granum is a part of the chloroplast. The chloroplast contains the chlorophyll pigment and it is necessary for the trapping of the energy present in the sunlight. As a result of this the photolysis of water takes place and hence water is broken down from water molecule to proton and oxygen.
Explanation:
Is it true that animals in the frozen ocean waters live longer than ocean animals elsewhere? Why or why not?
Question 5 options:
Yes, because animals that live there have no predators.
No , because most organisms migrate to warmer areas.
Yes, because animals that live there do everything much slower which expends less energy.
No, because most aren't equipped with the antifreeze-like substance in their blood.
Answer:
Yes
Explanation
Yes, because animals that live there do everything much slower which expends less energy.

Question 12 When cells get energy from glucose without oxygen it is called fermentation, cytoplasm, photosynthesis, phosporolation
Answer:
fermentation
Explanation:
Glycolysis is an ancient, major ATP-producing pathway that occurs in almost all cells, eukaryotes and prokaryotes alike. This process, which is also known as fermentation, takes place in the cytoplasm and does not require oxygen.

Look at the graph...What is the optimal temperature for this enzyme?
A. 60 degrees C
B. 45 degrees C
C. 15 degrees C
D. 35 degrees C
Answer:
B: 45 degrees C
Explanation:
However, above 40-45 degrees Celsius, enzymes are usually denatured and can no longer catalyse the reaction, because the hydrogen bonds are broken, so the enzyme permanently loses its shape. The temperature at which the reaction rate is fastest is the optimum temperature.
As per the graph, the optimum temperature for the enzyme is 45 degree Celsius. The correct option is C.
What is optimum temperature?The temperature at which the enzyme exhibits the greatest activity is referred to as the optimum temperature.
Enzyme activity decreases as the temperature rises or falls. It can even become inactive at times. It is equivalent to the body temperature of a warm-blooded animal.
The kinetic energy in the substrate and enzyme molecules is optimal for the maximum number of collisions at the optimal temperature.
At high temperatures, the enzyme's shape changes, and it no longer complements its specific substrate.
It is the temperature at which the enzyme's reaction rate is fastest. It will be the point on the graph where the line reaches a peak at 45 degrees Celsius.
Thus, the correct option is C.

Which of the following are all internal sources of Earth's energy that help drive convection currents below the crust?
A. Kinetic energy from the earth's rotation
B. thermal energy produced by gravity
C. thermal energy from decaying atoms
D. light energy produced in earth's geosphere
E. light energy produced in earth's crust
Answer:
D. light energy produced in earth's geosphere
Explanation:
Earth's internal heat budget is very important to Earth's thermal history. The heat flow from the earth's interior to the surface is estimated to be 47 ± 2 terawatts (TW) and originates from two main sources
The internal source of Earth's energy that helps drive convection currents below the crust is D. light energy produced in the earth's geosphere.
Convection current refers to the current that is formed as a result of differential heating. It should be noted that lighter warm material rises while the heavier cool material sinks.
The light energy that is produced in the earth's geosphere is necessary for driving convection currents below the crust. Energy is transferred through the oceans and the geosphere by convection.

The light glows bright in the house tonight
Not a darkness to be seen
A kingdom of light bright
And it looks like I'm the brightest
The electricity is zapping like this light storm outside

And the light that once controlled me can't light me up at all
It's time to see how I can shine
To test the limits and glow up
No light, no power, no darkness for me
I'm brightttt!!!!
Let it glow, let it glow
I am one with the light in the sky
Let it glow, let it glow
You'll never see me flow
Here I glow and here I shine

My light flows through the air into this house
My brightness is spiraling in light fractals all around
And one thought glows like a bright blast
I'm never going dark, the dark is in the past

Answer:
I think the answer would be C.
Explanation:
D is wrong for obvious reasons, elimanate any silly or impossible answers.
Since poly means muliple, and single means, not muliple (in most cases), B is elimanated.
Since Grapihic usaully refers to things that can been seen, where genic ussaully refers to more so like personality characteristics.
