Question: Suppose that you have come up with a way of enlarging single cells to such a degree that a DNA duplex has a diameter of 0.1 mm – about the thickness of a human hair. If you were to do that, how long a “hair” would the entire human genome […]
1- How is the DNA of prokaryotes organized? In chromosomes? If so, how many, what shape? 2- what are the characteristic shapes of individual bacteria cells? Give Latin and English terms. 3- why do Gram-positive bacteria retain the violet dye? 4- what is the difference between a chemolithotroph and a […]
If the environmental temperature follows the trigonometric function given by Te(t)=16, then a more accurate cooling law is given by the differential equation: dh/dt= ?k(H ? Te(t)), H(0) = 23.8 where H(t) is the body temperature of the cat and k is a kinetic constant of cooling. Find the solution […]
Phenylketonuria (PKU) is a disease that results from a recessive gene. Two normal parents produce a child with PKU. (a) What is the probability that a sperm from the father will contain the PKU allele? (b) What is the probability that an egg from the mother will contain the PKU […]
