Explain where photosynthesis takes place? What is the function of this organelle?
Damm [24]

Answer:

Chloroplast

its function is to create chemical energy using light energy

Explanation:

Photosynthesis occurs in chloroplasts which can be compared to mitochondria because they both produce energy for the organism. The Chloroplast contains within it a pigment, chlorophyll which captures the sun's energy and turns into energy which is used to create other parts of photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Chloroplasts are one of the many organelles found in the body, and are generally considered to have originated as endosymbiotic cyanobacteria. In this aspect, they are similar to mitochondria but are found only in plants and protist.

If the dna double helix in salmon contains 22% guanine, what is the percent of cytosine, thymine and adenine? express your answe
Oksanka [162]

Theoretically it is the Chargaff's rule which entails that the ratio of purines and pyrimidines are 1. So following that rule you can solve this question.

G (purine) = C (pyrimidine) and

A (purine) = T (pyrimidine)

So G + C  would be 28% and hence

A +C would be 72% i.e. 36% each.

Please note that their are certain modified bases besides these four are also there including methyl Cytosine, Methylated Adenine. But htese modification does not violate the Chargaff's rule and they follow standard Watson Crick base pairing.
