Many studies have indicated that there is some genetic influence on body weight and composition. Researchers have established a

variety of theories that attempt to explain why some individuals gain weight more easily than others and why weight can be so difficult to change long-term. Choose the correct statement about theories regarding genetic influence on weight status.
a. The thrifty gene theory suggests that some individuals have a "thrifty metabolism," which could help a person survive when food is scarce.

b. According to recent research, the FTO gene may increase feelings of satiety.

c. The set point theory indicates that bodies are meant to stay within a narrow weight range, which cannot be changed long-term.

d. Drastically reducing calorie intake causes BMR to increase, which helps individuals deviate from their "set point" for weight

Answer:

A

Explanation:

The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution, people are prone to obesity by storing energy as fat, an ability to take advantage of rare periods of abundance  and this is advantageous during times of food availability. individuals with greater adipose reserves would more likely survive famine. This tendency to store fat could lead to obesity.

FTO is an enzyme that is encoded in humans by FTO gene located on chromosome 16. Increase in this enzyme is associated with the regulation of energy intake but not feeding reward. Also, the set point theory indicates that bodies are meant to stay within a narrow weight range but it is susceptible to chnage overtime.

Constants are factors that are not changed in the experiment. Since the experiment is testing different colors of light on plant growth, light color is being changed, and is therefore not a constant. Hope this helps! :)

charle [14.2K]
Long ears have to be dominant:

If this IS true then these would be your 'parents':

L = long ears
l = curly ears

LL x ll

If you cross the homozygous recessive curly eared rabbit (ll) with homozygous dominant long eared rabbit (LL) you would get 100% Ll - all would look long eared.
