Solve the problem. Solve the equation. Show all of your work on your own paper.The amount of time it takes an object dropped from an initial height of h0 feet to reach a height of h feet is given by the formula How long would it take an object to reach the ground from the top of a building that is 410 tall? Round to the nearest tenth of a second.

Solve the equation. Show all of your work on your own paper. = m – 1

Determine whether the graph of the equation is symmetric with respect to the x-axis, y-axis, origin, or none of these. You must show all of your work algebraically on your own paper for full credit. y – 6 = x2

Determine whether the graph of the equation is symmetric with respect to the x-axis, y-axis, origin, or none of these. You must show your work algebraically for full credit.x = y2 + 6

A point mutation occurs in hemoglobin gene in sickle cell anemia.

Chernobyl Nuclear Power station explosion is an example of accidental exposure to mutagens.

A plant with purple flowers is allowed to self-pollinate. Generation after generation, it produces purple flowers. This is an example of hybridization.

Increasing environmental levels of mutagen is likely to lead to increasing frequency of deleterious alleles.

Colorblindness is a sex linked disease in which: XB –>X chromosome with normal dominant allele (not colorblind) Xb –> X chromosome with recessive colorblind allele Then, write the genotypes for the following phenotypes of red-green color blindness- a. normal male _____________ b. normal female carrying no colorblind alleles (Homozygous) _____________ c. colorblind male _____________ d. normal female carrying the colorblind allele (Heterozygous) _____________

______________ is random change in the sequence of DNA and ___________________ is a change in structure of chromosome.(chromosomal mutation / mutation)
