Answer:

The correct answer will be option-D

Explanation:

The process of photosynthesis release oxygen from the plant which is used by the organism on earth during cellular respiration.

The oxygen released by the plants is formed through the splitting of water molecules as a result of the transfer of electrons through the electron transport chain in the thylakoid membrane during the light-dependent reaction.

Since the released oxygen is the result of the light-dependent reaction and not the light-independent reaction or Calvin cycle where heavy oxygen isotope is utilized in the cycle.

Thus, option-D is the correct answer.

adelina 88 [10]

Answer:

The correct answer is option d) an interaction between nature and nurture.

Explanation:

This idea is supported by the interaction between nature and nurture. This means that all our genetically acquired aspects such as genes, inherited physical characteristics, etc. work together with the environment in which we grow, the relationship we observe in our family, the people with whom we interact and the environment in we were raised.

<u>Both concepts interacting with each other </u>form what is known as a language acquisition device.

Here it is established that all <u>children are born with the ability to learn language and reproduce it through what they observe around them</u>.

Be it the way your parents speak, the friends around you and anything in the environment that can influence this aspect.

Many studies have indicated that there is some genetic influence on body weight and composition. Researchers have established a
sukhopar [10]

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.
