Because smoking can cause many different bad things to happen to you some examples would be lung cancer or if you smoke while you are pregnant you cold cause premature or birth defects to the baby, alcohol can just be bad a lot of the time because people can become addicted and loose a lot of money on buying alcohol and/or smoking materials.
Dad: TtBb
Mom: ttbb
You have to use distribution for dihybrid crosses. Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait. So for example with Dad, I will number the traits:
T(1)t(2)B(3)b(4)
To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb. Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.
Cross:
tb
TB TtBb
Tb Ttbb
tB ttBb
tb ttbb
The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue
Explanation:
The chemicals are contaminant in the ground water system and they can inflict serious health hazards on humans when water is sourced from such polluted ground water system.
- Consuming contaminated water can lead to cholera and diarrhea.
- It makes ground water toxic and poisonous.
- Drinking contaminated ground water can lead to the introduction of heavy metals in the body.
- Chemical wastes containing radioactive materials can damage body tissues.
- They render ground water unsafe for drinking ans usage.
