"A test cross breeds one parent of a known genotype with a second parent of unknown genotype in order to determine the unknown genotype based upon the ratio of their offspring's traits. In order for this to work, the known genotype must be" A) Homzygous recessive
B) Homzygous dominant
C) Heterozygous recessive
D) Heterozygous dominant

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
