What caused the tree bark to become darker?
What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.
In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?
The light-colored moth had a higher rate of survival than the dark-colored moth.
In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
The dark-colored peppered moth had a higher rate of survival than the light-colored moths.
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.

Which is the role of restriction enzymes?
to isolate the selected gene
to cut DNA into fragments of different lengths
to move and separate the strands of DNA
to join the sticky ends of DNA fragments
Answer:
to cut DNA into fragments of different lengths
Explanation:
A restriction enzyme is a protein that recognizes a specific, short nucleotide sequence and cuts the DNA only at that specific site, which is known as restriction site or target sequence.
More than 400 restriction enzymes have been isolated from the bacteria that manufacture them. In live bacteria, restriction enzymes function to defend the cell against invading viral bacteriophages. Restrictions sites in the viral genome (a "happy accident" of nature, as far as the bacteria are concerned, since they don't appear to have any specific function in the virus) are cleaved by the bacterium's restriction enzymes, fragmenting and destroying the DNA of invading bacteriophages before it can incorporate into the host's genome and take over the cell.
A bacterium is immune to its own restriction enzymes, even if it has the target sequences ordinarily targeted by them. This is because the bacterial restriction sites are highly methylated, making them unrecognizable to the restriction enzyme.
Isn't evolution fantastic?
The correct answer is option C i.e. to cut DNA into fragments of different lengths.
what is restriction enzyme?A restriction enzyme is a bacterial protein that cleaves DNA sequences at sequence-specific places, resulting in DNA fragments with known sequences on both ends.
Certain laboratory processes, such as recombinant DNA technology and genetic engineering, require the use of restriction enzymes.
There are four different types of restriction enzymes: type I, II, III, and IV, which differ principally in structure, cleavage site, specificity, and cofactors.
Both restriction and methylase functions are carried out by a single big enzyme complex in Types I and III enzymes.
The restriction enzyme is independent of its methylase in the Type II system.
Several thousand type II restriction enzymes have been identified from a variety of bacterial species.
These enzymes recognize a few hundred distinct sequences, generally four to eight bases in length.
Type III restriction enzymes are a group of endonucleases that recognize a non-pallindromic sequence, comprising two inversely oriented sites.
Type IV restriction enzymes cleave only methylated DNA and show weak sequence specificity.
hence, the correct answer is option B.

Which of the processes offers the GREATEST evolutionary advantage of sexual versus asexual reproduction?
А
meiosis
B В
mitosis
С
budding
D
binary fission
Answer:a
Explanation:
The process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS.
Meiosis is a type of cell division that is used by organisms of sexual reproduction to produce haploid (n) gamete cells.Meiosis produces new genetic variation in offspring due to:
the random separation of alleles in gametes when chromosomes separate crossing-over or recombination which is the interchange of genetic material between non-sister chromatidsgametes randomly fuse to produce a diploid (2n) organismIn conclusion, the process that offers the GREATEST evolutionary advantage of sexual versus asexual reproduction is MEIOSIS because it is capable of introducing new alleles and increasing genetic variation in a population.

What is the elephant getting when the bond is broken in sucrose?
Answer:
Energy
Explanation:
The elephant is getting energy when the bond is broken into sucrose because as sucrose is broken down, it is hydrolized by enzymes sucrase which break the glycosidic bond and convert it to glucose and fructose in the upper gastrointestinal tracts. Glucose and fructose are then absorbed into the blood stream which glucose serve as energy source or stored as glycogen in the gastrointestinal tracts.

Answer:
: Mitosis and meiosis both are the types of cell division which occurs in the body of living organisms. Mitosis is responsible for growth and development in the body of cat because in mitosis, one cell is divided into two daughter cells and again these two cells divided into four and so on which increases size of organisms, while meiosis is responsible for the production of sex cells in cat which enables them to continue its breeding and produce fertile offspring.

how does matter move from the hydrosphere into the biosphere explain in your own words
Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
What is hydrosphere and biosphere?Hydrosphere:-
The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.
Biosphere:-
The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.
Evaporation:-
The process in which water or liquid converts into vapor is called as evaporation. In the case of water it starts vaporization at 100 degree C.
So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.
Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
