When cells divide during meiosis, homologous chromosomes separate independently of each other and are randomly distributed to the gametes. How does this process lead to genetic variability? *

During meiosis, gametes receive a full set of chromosomes, and the offspring resulting from fertilization have two full sets of chromosomes, and therefore, a larger number of gene combinations.

During meiosis, gametes receive different combinations of genes, and the offspring
resulting from fertilization have a unique set of chromosomes.

During meiosis, gametes receive the same genes, and the combination of gametes at
fertiliztion give offspring characteristics of both parents.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

Produce proteins by following coded instructions that come from the nucleus of the cell.
