Answer:
c
Explanation:
The correct answer would be that the nervous system transmits feelings of hunger to the brain, which initiates eating.
<em>The human stomach and intestinal tracts consist of receptors that are able to sense the presence or absence of nutrients and send messages to the brain accordingly. If there are adequate nutrients in the stomach and the intestinal tracts, the receptors send a message to the brain and the hormone that makes humans feel fullness in their stomach is released into the blood. Once the available nutrient is low, the receptors send a message to the brain which in turn releases hormones into the blood that makes humans feel the sensation of hunger. </em>
The correct option is c.
The correct answer is A.
The official guidelines from doctors state that infants should start consuming solid food after the age of six months. In order for the infants to be safe and healthy, they need to be able to sit up, support their back and chew safely before being given solid food.
Answer:
152.88 solar unit.
Explanation:
The haploid genome content of the human cell is 3.3 x 10⁹ bp but the human cell is diploid.
So, the content of the diploid cell = 2 ×3.3 x 10⁹= 6.6×10⁹ bp/cell.
1 cell contains DNA = 6.6×10⁹ bp/cell.
10¹³ cell DNA content = 10¹³ x 6.6×10⁹ = 6.6 x 10²² or 6.6 x 10¹⁹ kilo base pairs.
1 kilobase pair of DNA = 340nm = 340 × 10⁻⁹m.
6.6 x 10¹⁹ kilo base pairs of DNA = 340 × 10⁻⁹ × 6.6 x 10¹⁹ = 2244 x 10¹⁰m.
1 meter= 6.2 ×10⁻⁴ miles.
2244 x 10¹⁰m = 6.2 ×10⁻⁴ × 2244 x 10¹⁰m = 13912.8 ×10⁶ miles.
1 solar unit = 9.1 x 10⁷miles.
Then 13912.8 ×10⁶ miles = 13912.8 ×10⁶ miles/ 9.1 x 10⁷miles = 152.88 solar unit.
Total human DNA in terms of solar unit = 152.88 solar unit
Thus, the answer is 152.88 solar unit.
