The graph below shows the change in the frequency of one allele over 500
generations in a large population. Which of the following statements
describes the change depicted in the graph?
An allele simply refers to a variant form of a gene. Alleles are vital to the phenotype of an organism.
Your information is incomplete. Therefore, an overview of alleles will be given. An allele simply means the forms of a given gene variant. Alleles are genetic sequences. They code for the transmission of traits.
Alleles are the variant forms of genes which are located in the same position. The changes in allele frequencies can show that genetic drift is taking place or the introduction of new mutations.

explain how a mutation could have no effect on the organism that inherits the mutation
Answer:
A mutation could have no effect on the organism that inherits the mutation because of the chances of the organism's parents/producers. One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.

Explanation:
There are two stages to photosynthesis: Reactions of light and darkness. Light-Reaction takes place in thylakoid membrane.
What is Light-Reaction takes place during Photosynthesis?Autotrophic plants produce their own food through a process called photosynthesis. Sunlight, chlorophyll, CO2, and water are four crucial components needed for this process. It is a response that is light dependent.
In plants and some other creatures, a process known as the "Dark Reaction" harnesses the energy from the sun to change carbon dioxide and water into glucose (a sugar) and oxygen.
Therefore, a sequence of chemical events known as the "Light Reaction of Photosynthesis" are what is needed for the pigment found in leaves, such as chlorophyll, to transform light energy into chemical energy in the form of ATP and NADPH.

The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: ______________
a. humans have excellent protein repair mechanisms.
b. compared to other organisms, changes in human proteins have relatively small effects on their cells' structures and functions.
c. humans have excellent DNA repair mechanisms.
d. most of the human genome is noncoding DNA, so few mutations affect human proteins.
e. most of the mutations occur in somatic cells, not germ cells.
Answer:
The believe the correct answer is option E.
The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: most of the human genome is noncoding DNA, so few mutations affect human proteins. Therefore, the correct option is D.
What is a human genome?A human genome refers to the complete set of sequences of the nucleic acids that are present in the humans. The human genome contains a relatively large amount of noncoding DNA, which does not code for proteins and is therefore less subject to selective pressures.
Option A, humans have excellent protein repair mechanisms, and Option C, humans have excellent DNA repair mechanisms, are partially true, but do not fully account for the tolerability of new mutations in the human genome.
Option B and E are also not true, as changes in human proteins have relatively small effects on their cells' structures and functions, is not entirely true. Therefore, the correct option is D.

Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius

Which effect is most likely from a hurricane? damaged homes due to flooding forest fires due to lightning strikes cars sucked in due to a low-pressure center damaged personal property due to hail.
Answer:
A damaged homes due to flooding
Explanation:
Hurricanes cause heavy rains and strong winds. The heavy rain causes water to rise and therefore, homes are damaged by it.
A natural calamity in which a low pressure centered low atmospheric air movement along with strong winds and rain occurs is called a hurricane it is also known as a tropical cyclone.
The effect that most likely occurs due to a hurricane is:
Option A. Damaged houses due to flooding.
The effect can be explained as:
The hurricane can cause storm surge in which the levels of the sea rises than normal and causes high tides that can lead to floods.The heavy rainfalls and typhoons caused by hurricanes lead to floods that damage homes.Hail and forest fires due to lightning strikes are not caused by hurricanes and hence are not affected by the hurricane.Therefore, hurricane causes flooding.
