State the process of carbon cycling

Biology
1 answer:
STatiana [176]1 year ago
5 0

Answer:

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.

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.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.

The karyotype for trisomy 21 illustrates an example of a genetic mutation caused by A) insertion. B) inversion. C) crossing over
Katyanochek1 [597]

Trisomy 21, as illustrated by the karyotype, is caused by nondisjunction. This occurs when chromosomes do not separate properly during meiosis.

Answer is D) nondisjunction

A polypeptide only becomes a functioning protein after it has folded into its exact 3D shape.
makkiz [27]
True. A protein becomes functional only when it reaches its tertiary shape (3D). It is not necessary for the protein to reach the quaternary stage, but that is just a more complex functioning protein. It really is just two tertiary merged together. Example is red blood cells.
