The complete question is as follows:
Hypothesis Cas More Information: Here is a summary of the data, Mass of DNA Cat Res per Coll Mother Father Calix 1520 fg 1495 fg 1535 fg . The mass of an X chromosome is 40 fg. • Point mutations do not change the mass of DNA. • In chromosomal rearrangement, some daughter cells gain parts of chromosomes and some lose parts of chromosomes. • In nondisjunction, daughter cells gain a whole entire chromosome. Obe Exp Нур 는 Exp Point Mutation in Melosis Chromosomal Rearrangement Nondisjunction Choose the mutation that you think has caused Calix's calico fur coloring. Form a hypothesis to explain your reasoning. You will be able to revise your hypothesis as you collect more data.
Answer:
The correct answer is - non-disjunction.
Explanation:
Calix's calico has an X chromosome gene that determines the color of fur. One allele forms orange fur and the other give rise to black. In heterozygous give rise to orange patches on black.
Mother has autosome and 2-X chromosomes.
Mass of 2 X chromosomes will be
= 40*2
= 80fg
So mass of autosomes = 1520-80
= 1440fg
Mass of sex chromosomes in father is = 1495-1440
= 55fg
So the mass of Y=55-40
= 15fg
It is clear that the mass of DNA of Calix is exactly 15 more than DNA of the mother. So we can say that Calix has an entire Y chromosome in extra.
So the answer is non-disjunction.
Answer:
process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms.

Explanation:
Answer:
Explanation: ground water contamination is nearly
always the result of human activity. In
areas where population density is high and human
use of the land is intensive, ground water is especially vulnerable. Virtually any activity whereby
chemicals or wastes may be released to the environment, either intentionally or accidentally, has
the potential to pollute ground water. When
ground water becomes contaminated, it is difficult
and expensive to clean up.
To begin to address pollution prevention or remediation, we must understand how surface waters
and ground waters interrelate.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.
Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by a number of genes. When mitosis is not regulated correctly, health problems such as cancer can result.
The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half—from 46 to 23—to form sperm and egg cells. When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46. Meiosis also allows genetic variation through a process of DNA shuffling while the cells are dividing.
