An advantage of using natural gas, rather than oil, as a fuel is that natural gas is less of a contributor to global warming because it does not release CO2 when it burns less of a contributor to global warming because it does not release CO2 when it burns A less expensive because most reserves are in the United States less expensive because most reserves are in the United States B more abundant because it is a by-product of photosynthesis more abundant because it is a by-product of photosynthesis C cleaner because it burns more completely cleaner because it burns more completely D safer to store because it is a gas

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). this change in skin color provides evidence that -
