Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.
Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.
Answer 3: Genetics have proved that for those who sweat a lot and have armpit odor have wet earwax.
Answer 4: The wet type earwax is dominant one with honey brown or dark brown color while dry one is recessive.
Answer 5: As wet earwax is dominant trait, according to the given scenario the genotype of parent with wet earwax will be "WW" which when crossed with dry earwax parent will have all the offsprings with wet earwax.
Answer:
Men are, in general, more muscular than women. Women are just over half as strong as men in their upper bodies, and about two-thirds as strong in their lower bodies
The answer is D. The ribs PROTECT the lungs and the heart. They allow you to move and they store minerals such as calcium. However it is the brain and the blood vessels that regulate the body temperature not the skeletal system.
I think the propositions are :
Which organisms and set of characteristics are correctly paired?(1) fungi—carry out photosynthesis and heterotrophic nutrition(2) plants—carry out respiration and autotrophic nutrition(3) decomposers—carry out photosynthesis and autotrophic nutrition(4) animals—carry out autotrophic nutrition and heterotrophic nutrition
1): False because fungi do not have photosynthesis.
3) False because decomposers do not have photosynthesis.
4) False because animals do not have autotrophic nutrition.
2) is true because animal carries out respiration like other living organisms, and carry out autotrophic nutrition by photosynthesis.
Soil, Temperature, and water would be practically the 3 biomes or the aquatic ecosystems. They are both natural and enables you to live successfully. So as for the organism that live there, like plants, the sun supports the plants, also water, and also the soil from the ground. Therefore, those would be the 3.
