El ácido esteárico es un ácido graso saturado de cadena larga. No contiene ningún doble enlace en su estructura química. ¿¿Cuántos miligramos de hidrogeno hay en 35.7 g de acido esteárico CH3(CH2)16COOH? Considere los siguientes pesos moleculares: H=1,0 g/mol O=16,0 g/mol C=12,0 g/mol

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

genetic variation will increase because of a new habitat and food source.

explanation:

ans.

dna fingerprinting is defined as a process that determines the dna characteristics of an individual. these dna characteristics are unique among individuals as their fingerprints, so it is known as dna fingerprinting.

steps of dna fingerprinting includes extraction of dna from sample, amplification of dna, restriction digestion of amplified dna, and then analysis of dna by gel electrophoresis, respectively.

thus, the next step performed by the scientist is 'to cut the amplified dna (obtained by polymerase chain reaction) by restriction enzymes that cleave the dna into fragments and their analysis.'
