Answer:
The correct answer is "a supervision duty for a RDA".
Explanation:
According to the California Dental Practice Act, RDA establishes all the duties that a dental assistant is able to perform. These duties are limited, since they do not have the background and abilities that a dentist have during his career. However, a dental assistant could still perform many duties, including: mouthmirror inspection of the oral cavity and charting of obvious lesions.
Sealing terrarium will lead to water cycle, because water can not escape out. so vapours formed during day time will convert into water droplets at night.
Plants are photosynthetic. So, they prepare their own food by using raw materials from atmosphere like CO2, H2O and sun’s energy. CO2 is the carbon source for the synthesis of glucose through array of enzyme catalysed biochemical reactions taking place in chloroplast of plant cell.
Animals are heterotrophic in nutrition. So, they get energy; i.e. glucose from the food they eat. It depends on what is their food source. For example, herbivorous animals eat variety of plants, starch and cellulose of which become glucose source. Carnivorous animals eat other animals, whose stored glycogen or fat becomes energy source for them.
Explanation:
Some of the mice will be homozygous dominant (AA), others will be heterozygous (Aa) and others homozygous recessive (aa).
Because the population isn't homogeneous, the easiest way would be to mate all grey mice on one side, and all yellow mice on the other, and analyze the phenotype of the offspring.
The cross between mice with the recessive trait will have <u>100%</u> offpsring with the recessive trait.
However, the cross between mice with the dominant trait will show some recessive individuals in the offspring:
- AA x AA ---> all A_
- AA x Aa ---> all A_
- Aa x Aa ---> 3/4 A_, 1/4 aa
