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 
.
Answer:
Organisms differ in how they obtain energy, and they are classified as autotrophs or heterotrophs based on how they obtain their energy in an ecosystem. ... organisms that contain chlorophyll absorb energy during photosynthesis and use it to convert the inorganic substance carbon dioxide and water to organic molecules. Why?
Explanation:
Answer:
<u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
Explanation:
The funny bone isn't actually a bone, its actually a nerve that touches your humerus.It is the ulnar nerve, which travels down the arm posteriorly and eventually reaches the "cubital tunnel" and at this location (between the trochlea and medial epicondyle of humerus), ulnar nerve is called funny bone.
The nerve is relatively unprotected at this place.
A blow here may produce a tingling or a numbing sensation throughout the forearm and hand.
Hence, <u>Ulnar nerve</u> is also called funny bone and feels tingling sensation if <u>humerus </u>is bumbed. <u>Medial epicondyle</u> passes underneath this bony structure.
A testable question is a question that can be answered and solved by creating and conducting an experiment. Testable questions are often about changing one item to see what impact it has on another.
Example:
Does changing the height of the ramp affect the speed of the skateboard going down the ramp?
