Skeletal mass increases dramatically during childhood and adolescence, and decreases dramatically at the beginning of the fourth decade of life and decreases with age, with an exception of the skull.
Hope this helps! Have a BLESSED day! :-)
Answer:
The correct answer is - The extra energy is converted to fat and stored until needed.
Explanation:
When someone intakes more carbohydrates than they need at a particular time body converts the excess amount of the carbohydrate into glycogen and stored in the liver cells.
One glycogen level is full the insulin starts converting the carbohydrate into fatty acids that move to different parts of the body and stoored like adipose tissue in the belly and thigh.
Thus, the correct answer is - The extra energy is converted to fat and stored until needed.
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.
Answer:
Genes play an important role in determining physical traits — how we look —and lots of other stuff about us. They carry information that makes you who you are and what you look like: curly or straight hair, long or short legs, even how you might smile or laugh. Many of these things are passed from one generation to the next in a family by genes. Most cells have one nucleus. The nucleus is a small egg-shaped structure inside the cell which acts like the brain of the cell. It tells every part of the cell what to do. It contains our chromosomes and genes. Chromosomes come in matching sets of pairs and there are hundreds (sometimes thousands) of genes in just one chromosome. The chromosomes and genes are made of DNA.
