Ionic bonds are referred to two elements/molecules that form when one is classified as metal and another is classified as non-metal. Covalent bonds are two non-metal elements that bind together. They differ in several ways. Ionic bonds have a better force of attraction due to the metal element, whereas covalent bonds are formed using the Van de Waals force (which makes it weaker). Ionic bond also has higher melting and boiling point because of its force of attraction as compared to the covalent bond. Similarly, ionic bonds react to electricity where covalent does not.
Answer:
C
Explanation:
D in my opinion wouldn't be correct because a vaccine is for if you come in contact with the sickness you are more protected and helps build immunity. So healthy people get them to try and build immunity against said vaccine. Like if you have the flu, your body is fighting. In the Flu vaccine parts of the flu are in the vaccine to help your body learn to become immune. So option C.
Sorry if this is confusing, hope it helps!
Answer:
Option D.
Water and the xylem are both polar. Water molecules have the ability to form hydrogen bonds with each other and with the walls of the xylem.
xylem.
Explanation:
water is able to move upward from the roots of a plant, through its xytem in the stem, and out to the leaves because Water and the xylem are both polar. Water molecules have the ability to form hydrogen bonds with each other and with the walls of the xylem and it is as a result of water covalently bonded to it's molecules which is as a result of unequal sharing of electrons, i.e slightly positive and slightly negative molecules on the side or partly ionic make water and xylem to form intermolecular associations with the wall of xylem which make water to move upward through its xylem in the root, stem.
Answer:
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species. It is distinguished from genetic variability, which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments.
