Imagine that a probe sent to mars brings back a sample that contains a very primitive life-form, which appears similar to bacteria. scientists are able to revive it and begin to grow it in culture. much to their amazement, they discover that the organism has dna and that the dna encodes proteins. however, the dna of these martian microbes contains only two nucleotides. if the martian microbe uses triplet codons, what is the maximum number of different amino acids that it can have in its proteins

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?

Based on the data in your tables, did the light-colored moths have a higher or lower survival rate after the industrial revolution?

In pea plants, the allele for inflated pod seed, i, is dominant over the allele for constricted pod seed, i. the punnett square shows a cross for this trait. which offspring will be homozygous dominant
