I am assuming you mean the nutrient groups of macronutrients and micronutrients.
Macronutrients:
<em>fats</em>
<em>carbohydrates</em>
Micronutrients:
<em>calcium </em>
<em>zinc</em>
<em>vitamins</em>
Hope this helped :)
DNA Mutation is caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Thus, the correct answer is option D.
1.DNA Mutations are caused by environmental factors known as mutagens.
2.Types of DNA mutagens include radiation, chemicals, and infectious agents.
3.DNA Mutations may be spontaneous in nature.
1 is b or 1/4 (I'd recommend checking a punnet square too)
The answer is D. phobias. The little Albert experiment demonstrated that emotional responses can be conditioned in human beings. The 9 months boy was exposed to different stimuli which included a rabbit, masks, a white rat, burning newspapers and a monkey. After some time he was exposed to the white rat and later a loud noise of metal was made and it scared the boy. This exposure was repeated and eventually the boy became afraid of white furry things including animals.
