2. If the climate were to change in an environment,
it is more likely that some individuals within a
population will survive if
a. the individuals stop reproducing.
b. the individuals are genetically
identical.
c. there is genetic variation within the
population
d. the individuals reproduce asexually.
Answer:
C, there is genetic variation within the population
Explanation:
When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population. So, the correct option is C.
What is Genetic variation?Genetic variation is defined as the difference in DNA between individuals or between populations where there are many sources of genetic variation including mutation and genetic recombination. Mutations are the ultimate source of genetic variation, but some other mechanisms, such as genetic drift, contribute to it as well.
Genetic variation is caused by mutations that can create completely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis. When climate change occurs in an environment, it is more likely that some individuals within a population will survive if there is genetic variation within the population.
Therefore, the correct option is C.

Cancer cells exhibit uncontrolled and disorganized growth. Formation of new blood vessels is required to bring nutrients and oxygen to cancerous tumors. Cancer cells cannot enter the cell cycle and therefore are mortal. cancer cells enter the cell cycle repeatedly, and in this way they are immortal.
Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
Answer:
When the liver has broken down due to harmful substances, its by-products are exerted into the bile or blood. Bile by-products enter the intestines and leave your body in the form of feces. Blood by-products are filtered out through the kidneys and leave the body in the form of urine.
Explanation:
When the liver is damaged by harmful substances, their by-products move into the bile or blood, where the by-products of bile enter the intestines and leave your body as feces and by-products of the blood. -products are filtered through the Kidneys and leave the body as urine.
What is Excretion?Excretion is defined as the process in which metabolic waste is eliminated from an organism, this is done by the lungs, kidneys and skin in vertebrates.
This is in contrast to secretion, where matter may have specific functions after leaving the cell where excretion is an essential process in all forms of life.
Through excretion organisms control osmotic pressure which is defined as the the balance between inorganic ions and water and maintain acid-base balance.
Thus, when the liver is damaged by harmful substances, their by-products move into the bile or blood.

If the enzyme DNA helicase was denatured, what would be the immediate effect on DNA replication?
A) New nucleotides would not be added to the growing strand
B) original DNA strands would not be separated
C) sections of new DNA in the lagging strand could not be connected
D) DNA mutation rate would increase dramatically
If the enzyme DNA helicase was denatured, then original DNA strands would not be separated (Option B).
DNA helicase is a key enzyme that unwinds both DNA strands during DNA replication.In consequence, there would be no replication fork if this enzyme helicase) is denatured.DNA polymerase is the enzyme required to add new nucleotides to the growing DNA strands.In conclusion, if the enzyme DNA helicase was denatured, then original DNA strands would not be separated (Option B).

Write a research paper about do you believe in evolution? Why or why not?
Answer: Yes
Explanation: Evolution is a fact, but not all evolve at the same time, not all have the equality of the study and for this reason evolution is delayed worldwide.
Answer:
Yes, I belive in evolution because of how muech the world has changed it's form over they years. To break it down a little more take humans for an example we weren't always like this we didn't have all these citys, buildings, tec, and so on. Back in the days when we still have native tribes and explorers they didn't have a house to sleep in they slept in tents or in carrages but as time evolved so did our minds and our brains thats when cabins started then after that houses then cars, power, and even more, but they had to learn how to do this. They evolved their minds to create they evolved to make it throught bad times they had to evolve along with mother nature her self. we all made it this far thanks to the great mind of evolution adn thats why I believe.

What is a simulation?A simulation is a computer program or model that imitates a real-world system or process. It allows researchers, scientists, engineers, or other users to understand, predict, or test the behavior of a system or process under different conditions or scenarios. Simulations are used in various fields, including engineering, physics, chemistry, economics, medicine, and social sciences, among others.
They often involve mathematical or statistical models, algorithms, and computer graphics or visualizations to represent the system or process being simulated. By running a simulation, users can observe the results, draw conclusions, and make predictions about the behavior of the real-world system or process. Simulations can be helpful in decision-making, experimentation, training, and education, among other applications.

transcribe the following DNA sequence to RNA use no spaces in your answer and use all caps. DNA:TACGCTTTACGAGACCCAATC
Answer:
RNA: UACGCUUUACGAGACCCAAUC
Explanation:
During transcription, a specific DNA sequence is used as template to synthesize a specific RNA sequence, usually a messenger RNA (mRNA). During this process (transcription), Uracil (U) bases replace Thymine (T) bases. Transcription has three stages: initiation, elongation and termination. Subsequently, the resulting mRNA is used to synthesize a protein, in a process known as translation.
