Specific gravity is a property that describes how dense something is compared to water (density = 1 g mL ). For instance, sulfur has a specific gravity of 2.0, which means it has a density of 2.0 g mL . The table lists the specific gravity of four common metals. Making instruments to transmit sound is an important technological advancement. If a designer wants to transmit sound as quickly as possible through a wire made of one of these substances, which substance would she choose?

they may bind directly to special “promoter” regions of dna, which lie upstream of the coding region in a gene, or directly to the rna polymerase molecule.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

meiosis is the correct answer

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
