Q.1. Based on the information in the unit, explain why the number of predators is declining in the Appalachian region. What effects might this have on the forest?
Q.2. If trees in a timber cruise were found to be of many different species, would that mean that the forest could be used for timber? Explain your answer.
Predators population decreases due to loss of habitat, introduction of pests and expansion of residential spaces.
Why predators is declining in the Appalachian region?The number of predators is declining in the Appalachian region due to loss of habitat, introduction of pests and expansion of residential and recreational spaces. These factors also adversely affected the biodiversity present in the forest.
If trees in a timber cruise were found to be of many different species, then it would not mean that the forest could be used for timber because it has different types of species of trees. If we want to grow trees for timber we must cultivate similar type of trees.

Which best explains why males have a greater probability of being color blind than females?
A. Males only have to inherit the allele on the Y chromosome to be color blind.
B. Males only have to inherit the color blindness allele once to show the trait.
C. Males have to inherit two copies of the color blindness allele to show the trait.
D. Males have to inherit the allele on two X chromosomes to be color blind.
Answer: Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.

The shape allows the enzyme to make a new substrate.
The shape allows the reaction to go faster.
The shape allows the enzyme to bind with a specific substrate.
The shape allows the enzyme to make products.
Answer:
The shape allows the enzyme to bind with a specific substrate.
Explanation:
Substrates and enzymes are like puzzle pieces. They need to be specific shapes to fit together. When they fit together, they do their job wonderfully. If they are pushed together without being the correct shape, they could be damaged.
