Answer:
Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.

-What types of toxins were found in the waters of the Lower Passaic Superfund site?
-How were some fish able to survive PCB levels thousands of times higher than sensitive fish can withstand?
-What is the advantage of a large population for rapid evolution?
-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?
-What will likely happen to these toxin-adapted fish if the waters are eventually cleaned up?
Answer:
-What types of toxins were found in the waters of the Lower Passaic Superfund site?
DDT and agent orange were found in the waters of the Lower Passaic Superfund site.
-How were some fish able to survive PCB levels thousands of times higher than sensitive fish can withstand?
in some tolerant fish, the trigger for the changes that can be caused by PCB levels are can be turned off which allows some fish to survive levels of PCB thousands of times higher than the levels affecting sensitive fish.
-What is the advantage of a large population for rapid evolution?
The advantage of rapid evolution is that the animals can survive and not get killed off.
-Do you think all species would be able to evolve adaptations to help them survive pollutants? Why or why not?
I don't think that all fish can get speedy evolutions like the killfish did because researchers think that they got a rare mutation which helped them survive. However as researchers say, in smaller populations with less diversity the chances that a rare mutation might happen is small.
-What will likely happen to these toxin-adapted fish if the waters are eventually cleaned up?
Once the water becomes clean, a tolerant fish with the mutation won't do as well as a sensitive fish would do.

Answer:
QUESTION:
How many cells does a human body have?
ANSWER:
30 trillion
Humans are complex organisms made up of trillions of cells, each with its own structure and function. Scientists have come a long way in estimating the number of cells in the average human body. Most recent estimates put the number of cells at around 30 trillion. Written out, that's 30,000,000,000,000!

Why do classification systems change over time?
O Scientists find new evidence in their studies.
O Scientists use old methods of classification.
O Scientists repeat experiments and find no changes.
O Scientists find similar evidence to previous work.
Classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).
What is Classification System?There are many types of classification systems that are used for different purposes. The classification of organisms takes place in the form of a classification system called Linnaean classification.
Linnaean classification involves the use of organisms grouped using a hierarchy called taxa which includes taxonomic levels and taxonomic groups that animals are placed in based on their characteristics and even shared ancestry.
The different levels of biological classification are as follows:
Species » Genus » Family » Order » Class » Phylum » Kingdom » Domain
It changes over time as scientific studies find new evidence.
Thus, classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).

Transcribe the following G G C C G T T T C A C C to mRNA
a) CCG GCA AAG TGG
b) CCG GCU AAG TGG
c) CCG GCU AAG UGG
d) CCG GCA AAG UGG
Answer:
The Answer is D, trust. I got all of them wrong and the system showed that this was the correct one.
Explanation:
The transcription of G G C C G T T T C A C C to mRNA is CCG GCA AAG UGG. Hence, option D is correct.
What do you mean by Transcription?Transcription may be defined as a biological process that involves the transformation of a DNA strand into its mRNA sequence. It occurs in the nucleus of the cell.
In mRNA, Adenine is transcribed into Urcail instead of thymine. So, the mRNA sequence will be synthesized according to that.
Therefore, the correct option for this question is D.

which statement is true about natural selection?
Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.
In a healthy ecosystem the interdependence between organisms is balanced?
Answer:
fierce competition to strengthen the system
Explanation:
Imagine that all of the sunlight is blocked from reaching Earth's
surface. What kind of organisms would be impacted first? *
O producers
O primary consumers
O secondary consumers
O tertiary consumers
O decomposers
Answer:
The correct answer is - producers.
Explanation:
Producers are organisms that are capable of making their food and energy on their own with the help of light energy get from the sunlight. These are the base of any ecosystem due to the fact that all the organisms depend directly or indirectly on the producers for food and energy.
So, if all the sunlight is blocked from reaching the earth's surface producers will be affected first in terms of ecosystem and trophic level.
Thus, the correct answer is - producers.

which structure in the figure would most likely be used to form muscles and connective tissue
Q3 because the muscle tissue isnt that complex and it inst that connective.Explanation:
Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.
What is connective tissue?Animals have a specific tissue called muscle that contracts when activated, applying forces to various body parts. Together, these fibers and sheets are referred to as muscles, which regulate many other contractile processes as well as an organism's movements.
Depending on their purpose, animals have one of three types of muscle. Despite modest differences, these muscles have a similar structure and function. Muscle tissue has a unified function and is frequently joined by the same nerve bundles.
Therefore, Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.
