What are the two most convincing pieces of evidence that both genetic and environmental factors play significant roles in the development of obesity?
Answer:
Explanation:
Obesity is a condition in which the individual becomes overweight. The main factors contributing to obesity are both genes and the food intake. As obesity has been found as genetically inherited trait in human beings the trait will pass from parents to offsprings. The food intake also contributes to the fact that how a body has been nurtured, that is if a person consumes fat rich diet on daily basis he is expected to gain overweight.
A research experiment was conducted on the identical twins who were nurtured at different geographical locations they were kept on controlled diet conditions but they showed same pattern of weight gain. This indicates that genes play important role in development of obesity.

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.Based on the experimental design, what is the independent variable?
A. Number of hatchlings B. Time eggs spent in ground C. No cloaca film on eggs D. Inducing egg laying
When a region of DNA must be repaired by removing and replacing some of the nucleotides, what ensures that the new nucleotides are in the correct sequence?
A) DNA cannot be repaired and this explains why mutations occur. B) Specific enzymes bind the correct nucleotides. C) The new nucleotides base-pair accurately with those on the complementary strand. D) The repair enzyme recognizes the removed nucleotide and brings in an identical one to replace it. E) The three-dimensional structure determines the order of nucleotides.
