The blue color of the sky results from scattering of sunlight by air molecules the blue light has a frequency of 7.5x10^14Hz cal

ELEN [110]2 years ago
5 0

Answer:

Explanation:

Electromagnetic waves all travel at the speed of light when in vacuum, and essentially this same speed in normal air. Since wave speed is product of frequency and wavelength, c = f λ and λ = c/f = (3.00 x 108 m/s) / (7.5 x 1014 Hz) = 4.00 x 10-7 m = 400 x 10-9 m = 400 nm.

Boris Magasanik collected data on the proportion of each base in RNA from different species. To compare the relative amount of e
just olya [345]

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.

A close relationship between unrelated organisms in which one organism benefits and the other is unaffected is known as
Andrews [41]
Answer:
A relationship between unrelated organisms in which oneorganism get benefit and the other is not affected is known as commensalism.
Explanation:
In commensalism organism live in a symbiotic association. the best example is the growth of epiphytes on the top or surface of orchid plants. The epiphytes obtain nutrients from orhids while in return orchids have no benefit from epiphytic plants.
