The sodium also has a atomic number of 11
Answer:
c. snake
Explanation:
A snake refers to a cold-blooded living organism that does not have leg such as cobra, python, anaconda, viper etc.
Ophiology can be defined as the study of snake.
Basically, ophiology is a branch of a field in science known as herpetology, which deals typically with the study of amphibians and reptiles such as lizards, frogs, snakes, crocodile, alligators etc.
Therefore, an individual who is an expert or professional in the study of snakes is generally referred to as an ophiologist.
The right option is a. contour interval
The difference in elevation between the highest and lowest contour lines on a topographical map is called contour interval.
A contour interval is the vertical distance between the two contour lines (highest and lowest) in a topographical map. The contour interval is usually stated explicitly on the right-hand lower part in every map. 20 feet for a 1:24,000 map scale is the frequently used contour interval and different contour intervals is available for different maps.
Answer:
C.) crystalline solids
Explanation:
The solid materials may be crystalline or amorphous. The concept of crystal structure is related to the organization of atoms in a geometrical form. Crystalline structures are present in various materials, where atoms distributed within their structure form a network called the crystalline lattice. Therefore, crystalline structures have salts, metals and most minerals. Crystalline structures are formed by unit cells that are their basic unit, as they constitute the smallest set of associated atoms found in a crystalline structure.
The molecules of the crystalline structures can have two types of bonds, the directional ones, which include the covalent and dipole dipole and the non-directional ones where the metallic, ionic, van der Walls bonds. When formed by ionic compounds, these crystalline structures can result in crystalline solids.
