Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Answers
Relation between mitosis and chromosomes:
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 certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.

X-rays carry a small risk of damaging DNA which can lead to cancer. Why are they still used by doctors?
Answers
Answer:
Despite the risk of DNA damage and cancer production, X-rays are still used by doctors because the benefit of this diagnostic study outweighs the risk, which in most cases is very low.
Explanation:
Diagnostic radiology studies, such as X-rays and CT scans, are procedures that use ionizing radiation to obtain images of the inside of the body. Prolonged or constant exposure to this type of radiation is harmful because there is a risk of producing damage to DNA and can lead to the development of cancer.
However, the use of X-rays and CT scans are non-invasive diagnostic methods whose information provides an accurate diagnosis of a disease and, when well used, has a very low risk of organ damage.
Ionizing radiation is measured in milisieverts (mSv) and exposure from radiologic studies is in the range of 0.1 to 10 mSv per study. The amount of ionizing radiation a person is expected to receive per year from exposure to their environment is in the order of 3 to 5 mSv per year, so diagnostic imaging studies involve a low risk of organ damage.
Doctors continue to use X-rays as a diagnostic study, despite the risk of cancer and DNA damage, because the benefit —accessible, noninvasive, and cost-effective— far outweighs the risk.

Why is suburban sprawl tightly linked with environmental problems caused by
transportation?
A. Commuters who live in suburbs are dependent on automobiles that emit air
pollution.

B. Commuters who live in suburbs are more likely to walk and suffer from air
pollution
C. Commuters who live in suburbs are dependent on mass transit systems that
emit air pollution.
D. Commuters who live in suburbs are dependent on mass transit systems that
add to water pollution.
Answers
Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.
Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.
IMHO car pooling and mass transit needs to be used more to reduce environmental harm.

Name the ionic compound of Cu2(SO4)3?
Answers
Answer:
cuprous sulfate
Explanation:
Copper(I) sulfate, also known as cuprous sulfate and dicopper sulfate, is the chemical compound with the chemical formula Cu2SO4 and a molar mass of 223.15 g mol−1. It is an unstable compound as copper(I) compounds are generally unstable and are more commonly found in the CuSO4 state.
Hope this helped :)
The name of the given compound Cu₂(SO₄)₃ is copper (I) sulfate.
To name the given compound, first determine the oxidation number of copper in the compound as shown below;
[tex]Cu^{2+} \ + \ (SO_4)^{2-}[/tex]
2x = 2
x = +1
The compound can now be named starting with copper followed by its oxidation number, the lastly is the radical. The radical is sulfate.
Thus, the name of the given compound Cu₂(SO₄)₃ is copper (I) sulfate.
