Crossing over? That involves the random exchange of chromosomes.
Meiosis differs from mitosis in the number of chromosomes in each ending cell. In addition, one of the purposes of meiosis is to reduce the chromosome number in each cell by half and meiosis contains two rounds of division which is meiosis I and meiosis II and ends with four gametes that are not the same genetically.
Set up the equation.
Since gravity and liquid densities are fixed (for the most part), the height of the liquid is the largest variable in the equation. The equation reads as Pfluid = ρgh, where ρ is the density of the liquid, g is the acceleration of gravity, and h is the height of the liquid (or depth of the fluid)
Temperate grasslands have hot summers and cold winters. Summer temperatures can be well over 100 degrees Fahrenheit, while winter temperatures can be as low as -40 degrees Fahrenheit. They typically have between 10 and 35 inches of precipitation a year, much of it occurring in the late spring and early summer.
Answer:
Explanation:
Natural selection only acts on the population's heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency—a process known as adaptive evolution.
