A phylogeny is an evolutionary ”tree” of related
organisms that can be constructed by using
information obtained from the genetic material.
Genetic information is contained in all living cells,
in the form of long DNA molecules that take the
shape of connected double- stranded spirals
(DNA stands for deoxyribonucleic acid). DNA
spirals, or “helixes”, are tightly compressed in the
nucleus of every cell. Their information is
organized into a code made up of four small
molecules — the building blocks of DNA. The
molecules, called nucleotides, are labelled:
A (adenine), C (cytosine), G (guanine) and T
(thymine).
It is possible to draw conclusions about the
evolution of a group of plant or animal species,
and the relationships among them, by comparing
selected pieces of DNA.
Answer:
• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.

• pH level of an acid;
- Strong acid → 0 - 3.8
- Weak Acid → 4.0 - 6.7
Muscular dystrophy is a muscle disease that causes a loss in muscle mass and weakness. Patients with muscular dsytrophy may experience a weakening in their cardiac muscles, causings heart malfunction. Muscular dystrophy can also deteriorate the diaphragm, a muscle that solely aids in respiration, causing a breathing malfunction.
Carbon dioxide is a reactant and oxygen and glucose are products.
