Ethyl alcohol is one of the series of organic chemical compounds
in which a Hydrogen (H) attached to carbon is replaced by a hydroxyl (OH). It
is made from sugar, starch and other carbohydrates by fermentation with yeast
and synthetically from ethylene or acetylene. It has been used in beverages
which has unstable, combustible, colorless liquid with slight distinctive odor.
The amount of Ethyl alcohol in any drinks can be determined by multiplying the
percentage (%) of alcohol and size.
Frog's tongues are attached to the front of their mouths rather than at the back like humans. When a frog catches an insect it throws its sticky tongue out of it's mouth and wraps it around its prey. The frog's tongue then snaps back and throws the food down its throat.
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
