Answer:
The contaminated water contains harmful chemicals which results in the cracking of rock.
For example: The feldspar crystals within the granite react with the water chemically to form clay minerals which makes the rock weak and hence result in weathering.
How does a catalyst work?
Answer:
A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. This process is called catalysis. A catalyst is not consumed by the reaction and it may participate in multiple reactions at a time.

Explanation:
Margaret Mead lived in New Guinea in the 1930s to conduct her study of cultural variation.
What is cultural variation?Cultural variation makes reference to the rich range of cultural practices found in diverse cultures all over the world.
Gender roles, economic systems, and social structure, among a variety of other humanely as possible organized behaviors, all change from one culture to the next.
Margaret Mead conducted actual first-hand observational data of the shared, behavior patterns of several small societies in New Guinea to find out.

What is colon cell?IECs, which line the surface of the intestinal epithelium, are crucial for food digestion, nutrient absorption, the body's defense against infections from microbes, among other functions. Adenocarcinoma, the most prevalent type of colon cancer, develops in the glands that secrete mucus and is the primary cause of colon cancer diagnoses.In order to regulate mucosal immunity, coordinate food recycling, and create a mucus barrier, the colonic epithelium allows host-microorganism interactions. Inflammatory bowel illness is caused by a breach in the epithelial barrier (IBD).A colon polyp is a little cell cluster that develops on the colon's lining. Colon polyps are usually not harmful. But over time, certain colon polyps can transform into colon cancer, which, if detected in its later stages, can be fatal.

The gene for the hair pattern called a "widow's peak" is dominant. In a population of 100 people, 50 people have a widow's peak. How many people would you expect to be heterozygous for the trait?
50 people because the widow's peak is dominant. Those who don't have a widow's peak do not have the gene.
If the gene for the hair pattern "widow's peak" is dominant, it means that individuals with at least one dominant allele will express the trait. We would expect 50 people to be heterozygous (Ww) for the widow's peak trait.
Heterozygous refers to a genetic condition in which an individual possesses two different alleles for a specific gene. Alleles are alternate forms of a gene that can code for different variations of a particular trait. In a heterozygous individual, one allele is dominant and the other is recessive.
The dominant allele is expressed in the phenotype, meaning it determines the physical appearance or characteristic, while the recessive allele remains hidden and does not show in the individual's observable traits. The notation for a heterozygous trait is typically represented by two different letters, one for each allele (e.g., Aa).
Assuming that "W" represents the dominant allele for widow's peak, and "w" represents the recessive allele.
Given that 50 people in the population have a widow's peak (homozygous dominant, WW), we can deduce that the other 50 people must have the genotype for heterozygous (Ww) to express the trait.
