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:
Option A, 9:7
Explanation:
Given,
Genotype of A-B- have purple color
A-B- have genotype AABB, AaBb, AaBB, AABb
While genotype of A– bb, aa B–, and aa bb have white flowers
A– bb have genotype - AAbb, Aabb
aa B– have genotype aaBb, aaBB
Cross between Aa Bb and AaBb will give following offspring
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb AAbb aaBb aabb
So the possible genotypes and their corresponding phenotypes are
AABB-1 (Purple)
AABb-1 (Purple)
AaBB-3 (Purple)
AaBb -4 (Purple)
AAbb-2 (White)
Aabb-1 (White)
aaBB-1 (White)
aaBb-2 (White)
aabb-1 (White)
Purple : White = 9:7
I don’t know but i know for sure it’s not D
A hereditary trait is one that is genetically determined. Inherited traits are passed down from parent to child according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and the environment....
Explanation:
Feeding: moves carbon in the form of biological molecules along the food chain.
Respiration: when living organisms (plants, animals, and decomposers) release carbon dioxide into the atmosphere (this is a form of excretion ).
