Answer:

Ionic

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.  

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

calcium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for calcium is 1. There is large difference is present. That's why electron from calcium is transfer to the chlorine. calcium becomes positive and chlorine becomes negative ion.

There are two valance electrons in calcium so it needed to lose two valance electrons to complete the octet while chlorine needed one electron to complete the octet. Thus two electrons lost by one calcium atom are gained by two atoms of chlorine.

Ca + Cl₂ → CaCl₂

Answer:

Competition for food happens when there is a limited amount of food resources available. The members of a species that eat that food who are best adapted to access the food are more likely to reproduce and pass on their genes to the next generation.

For example, we have a bird feeder with a narrow opening for food. The small-headed birds can reach the food, the bigger-headed birds cannot. If this was the only food source for this area, then over time, there would be more smaller-headed birds than large-headed birds, due to the competition for food and success/lack of success.

77julia77 [94]

Answer:

Following information are needed to classify an organism.

1. Unicellular or multicellular : First we have to see that from how many cells the body of organisms formed.

2. Composition of cell wall: Secondly we have to see the cell wall composition.

3. Prokaryotic or eukaryotic cell: We have to see the nucleus of organisms, if it has nucleus we can say that it is a eukaryotic cell.

4. Mode of nutrition: Mode of nutrition means is the organisms is autotroph or heterotroph.

If they have similarities, so it is placed in one group. If not so it is placed in different group or kingdom.
