How did the peppered moth's environment change, and what caused this change?
Answer:
Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.
Explanation:
The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.
During the Industrial Revolution, pollution darkened tree trunks in England. This favored dark moths, causing a decline in lighter ones.
What are peppered moths?The peppered moth's environment changed due to the Industrial Revolution in England during the 19th century. Prior to the Industrial Revolution, the trees in England were predominantly light-colored, and the majority of peppered moths were also light-colored, or "typica." However, as a result of industrial pollution, the bark of the trees darkened, becoming covered in soot and ash.
This created a selective advantage for the dark-colored peppered moths, or "melanics," who were better camouflaged against the darkened trees. The change in the moth's environment was caused by the burning of coal in factories, which released soot and other pollutants into the air, leading to widespread pollution and industrialization. This phenomenon is often cited as an example of natural selection in action, as the moths adapted to their changing environment through the evolution of their coloration.

How can you the sex of the individual from the karyotype?
Answer:
There are 22 numbered pairs of chromosomes called autosomes. The 23rd pair of chromosomes are the sex chromosomes. They determine an individual's sex. Females have two X chromosomes, and males have an X and a Y chromosome.
This is how you know if a karyotype is male or female?
Answer:
Females have two X chromosomes, and males have an X and a Y chromosome.

1. New chromosomes remain attached to
cell membrane
2. Proteins check for errors
3. Starts at one place
4. Proceeds in two directions
5. Copies of DNA condense into
chromosomes that separate
6. Starts at many places
Answer:
1. New chromosomes remain attached to cell membrane - Both
2. Proteins check for errors - Both
3. Starts at one place - Prokaryotes
4. Proceeds in two directions - Both
5. Copies of DNA condense into chromosomes that separate - Both
6. Starts at many places - Eukaryotes
Explanation:
The difference between prokaryotic and eukaryotic DNA replications is associated with the origins of replication, that is, the locations where replication starts. While in eukaryotic DNA, the origin of replication occurs in several places along the strands of DNA, replication in prokaryotic DNA has a unique origin of replication.
Replication of a cell refers to the formation of the two alike copies of DNA it is crucial for biological legacy, cell growth and division.
The process of replication in prokaryotes and eukaryotes somewhat contrasts from each other.
1. New chromosomes remain attached to cell membrane - Both in prokaryotes and eukaryotes.
In prokaryotes, the single circular chromosome remains attached to the cell also in eukaryotes chromosomes remain attached to the nuclear envelope.
2. Proteins check for errors - Both in prokaryotes and eukaryotes.
Although the process of formation of proteins is different proofreading occurs in both types of organisms.
3. Starts at one place - Prokaryotes.
Replication in prokaryotes originates from only one place while eukaryotic replication can occur from multiple positions.
4. Proceeds in two directions- Prokaryotes.
Replication in prokaryotes is bidirectional and advances in two directions.
5. Copies of DNA condense into chromosomes that separate - Both in prokaryotes and eukaryotes.
DNA condenses in the nucleoid which later gets separated.
6. Starts at many places - Eukaryotes.
In eukaryotic replication, the DNA strand has multiple sites of origin and the replication can occur at multiple positions.

What is the difference between a dominant trait and a recessive trait?
Dominant traits will be expressed even if there is one of them while for recessive both of the parents have to have a recessive trait
Answer:
Dominant traits will always be expressed if any amount is there. Recessive traits will only be expressed if two are there.
Answer:
If a trait is dominant, then you will only have to have at least one parent with a dominant trait for the offspring to inherit the trait.
If a trait is recessive, then you will only need one parent with a recessive trait for the offspring to be able to inherit the trait.

most cells underego apoptosis if their dna is damaged. How can this be beneficial to an organism? someone pls help
Answer:
It prevents the cell from passing on those defects to other cells through DNA replication in cell division. By self destructing before it gets the chance to divide, whatever problem the cell had ends right there and doesn't propagate in the organism.

Amino acids for given RNA strand is Serine - Leucine - Cysteine - Aspartic acid - Leucine.
There are 20 amino acids that are present in nature and are necessary for a number of biological functions. Although the molecular structures of these amino acids vary, they all have a core backbone made up of an amino group, a carboxyl group, and a side chain. Each amino acid is distinct due to its side chain, which also gives it special characteristics and abilities. Hydrophobic, hydrophilic, acidic, basic, and aromatic side chains can all be divided into different categories. How amino acids interact with their surroundings and other compounds is determined by this classification. Amino acids for given RNA strand is Serine - Leucine - Cysteine - Aspartic acid - Leucine.

Explain how the fossil described above supports the idea of plate tectonics?
Answer:
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.
This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.
Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.
