Suppose no crossing-over takes place. use step 5 (anaphase 1) to explain why meiosis will still increase genetic variation.

Meiosis increases genetic variation due to random segregation which occurs.

In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg 

where in your body is there an enzyme that does function at a high or low ph? what is the name of that enzyme and its function?
