Uranium-235 is the answer
This is called active transport. The proteins use ATP to transport stuff in and out of the cell.
Answer:
Polygenic inheritance
Explanation:
When multiple genes present at different loci on chromosomes regulate a single genetic trait, the trait is said to be polygenic and the inheritance is a polygenic inheritance. The phenotype of the individual is regulated by an allele of each gene in an additive manner. The sum total of phenotypic effects of each allele of all the genes determines the final phenotype of the individuals.
These traits not present in discrete contrasting pairs (such as tall and short) but exhibit quantitative variations. For example, skin color in humans is regulated by multiple genes and the phenotype of the individual ranges from very light to very dark with many intermediates in between.
Acids are substances that provide hydrogen ions (H+) and lower pH, whereas bases provide hydroxide ions (OH–) and raise pH. The stronger the acid, the more readily it donates H+. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. ( source : https://courses.lumenlearning.com/wmopen-nmbiology1/chapter/the-ph-scale/ )
