To demonstrate DNA replication, Doug draws a model on construction paper. NITROGENOUS
BASES
SUGAR PHOSPHATE
BACKBONE
In order to show replication, Doug should carry out which of the following steps first?
SC.912.L. 16.3
Fold the model in half lengthwise.
Cut the nitrogenous base pairs where they meet.
Draw a second, identical model of a DNA molecule.
Separate the nitrogenous base pairs from the sugar phosphate backbone.

Place the steps tor the formation of the enzyme pepsinogen in correct order

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?
