The figure above shows two different systems. Each system contains a flask holding an unknown liquid at room temperature. Their masses are recorded on a digital balance at 0, 1, 2, 3, 4, & 5 minutes. The corresponding masses are recording in the data table above.
Which uncontrolled variable most likely explains the reduction in mass in System 1)
A)
the liquid is evaporating
B)
digital balance error in system 1

C)
the liquid is dissolving inside the flask
D)
water is condensing on the outside of the flask

Which is an example of a decomposer? a. bear b.algae c.grass d.bacteria d bacteria

Scientific evidence is most likely to be consistent if it is based on data from

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.
