Researchers investigated factors that affect tick populations in their habitats. They recorded the number of black-legged ticks, acorns, and chipmunks in an area over several years. The table below shows their results. Year Acorns Per
Square Meter Chipmunks Per
5 Acres Ticks Per
100 Square Meters
1994 18 12 10
1995 4 56 3
1996 10 8 14
1997 4 26 4
1998 15 9 14

Which of the following claims best explains the data?
A.
When the chipmunk population decreases, the ticks begin to eat acorns, which increases the tick population and decreases the number of acorns.
B.
When a lot of acorns are on the ground in a certain year, it is likely that there will be large populations of chipmunks and ticks in that year.
C.
A shortage of food for chipmunks in a certain year decreases the chipmunk population in the next year and the tick population in the year after that.
D.
When the tick population increases, the ticks cause the chipmunk population to decrease, and this causes the oak trees to stop producing acorns.

Suppose a point mutation, such as a change from an adenine to a guanine, occurs in the genome of a human sperm cell. the mutation could occur in any region of a gene. the effect of the mutation on the phenotype of the offspring will be determined by where the mutation occurs and its effect on the final gene product. in which of the following scenarios could the mutation alter the phenotype of the offspring? select all of the scenarios that apply the mutation occurs in the promoter and affects the rate of gene transcription. the mutation results in a new, dominant allele the mutation occurs in a portion of an intron not responsible for exon splicing the mutation occurs in a gene that controls development and alters differentiation of a cell type during development. the mutation occurs in a codon and alters the function of the final protein e mutation occurs in a codon, and the amino acid sequence of the final protein is unchanged.
