DNA is composed of nucleotides, which are composed of three parts:
1. A five carbon carbohydrate (pentose)
Pentose is classified as a monosaccharide (simple carbohydrate), and its molecular formula is represented by 
. They are water soluble molecules with sweet taste. Monosaccharides may have from three carbon atoms (trioses) to six (hexoses). In DNA is present pentose (5 carbon atoms)
2. A nitrogenous base
Nitrogenous bases are ring-shaped compounds that contain nitrogen in their molecular structure. They are classified into two groups: purines and pyrimidines
The purine bases are adenine (A) and guanine (G). They are larger and contain more than one ring in their structure,.
The pyrimidines, cytosine (C), uracil (U) and thymine (T), are smaller and composed of a single ring.
3. One or more phosphate groups
A phosphate consists of a trivalent anion that contains one phosphorus atom and four oxygen atoms. Its molecular formula is expressed by 
.
The similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.
<h3>What is photosynthesis rate?</h3>
The photosynthesis rate is the amount of photosynthetic products (i.e., glucose) that generates by a plant in a given unit of time, which depends on the amount of chlorophyll.
In this case, low-light seedlings and moderate-light seedlings produce amount of chlorophyll at a similar rate until 12 hours, while the maximized value for moderate-light seedlings and low-light seedlings is 48 hours.
In conclusion, the similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.

The answer is ‘the only truly distinctive primate trait’. Prehensile hands are a distinctive trait of primates an opposable thumb (capable of grasping). The digits have nails instead of claws, and tactile pads enriched with sensory nerve fibers at the ends of digits to feel to manipulate objects.
Cells relate to your genes via genetic code. The genetic code is also what tells the cells what type of cell to become (brain cell, stomach cell, etc.)
Answer:
Knowledge gain through observation and experimentation.
Explanation:
Science is the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. That knowledge which can be gain through observation and experimentations is considered as scientific knowledge and those knowledge which can be attain through other sources not observation and experiments is known as non-scientific knowledge so we can say that observation and experiments provide scientific knowledge.
