Answer:
The density of the liquid is 0.87 g/ml
Explanation:
Density = 17.4g divides 20ml = 0.87 g/ml (rounded to one significant figure)
Answer:
E
Explanation:
Hardy-Weinberg principle states that frequency of alelle and genotype will remain constant in the absence of genetic disturbances such as mutation, no change in the DNA sequence, the population must be large and others
the principle is defined by the equation
p² + 2pq + q² = 1
where the frequency of the dominant allele is p, and the frequency of the recessive allele is q. Going by the what is given which is for the carriers is 0.04 = 2pq
substitute the value into the expression
p² + 0.04 + q² = 1; The information is not enough to calculate either p or q going by the equation generated.
Answer: water travels from high to low concentration of the solute
Electrolytes are known to
be major components pf body fluid and these electrolytes enter the body through
foods. Thus, major regulation of body fluid and electrolyte balance in the body
is through the process of osmosis. However, osmosis can be defined as the
movement of water through the semipermeable membrane from lower concentration
of solute to higher concentration of solute.
Answer:
D. Some of the bacteria may be resistant and survive.
Some molecules are too big they cannot diffuse through the membrane, for example starch (glucose) molecules.
