Correct answer is a. intertidal zone
Answer: C): the number of unpaired electrons.
Explanation: A covalent bond is a type of chemical bond formed by sharing equal number of electrons between two non-metal atoms so that both can attain the a stable octet or duplet structure of noble gases. The electrons shared by two non-metal atoms are the unpaired electrons. For example, in the formation of a chlorine molecule, a chlorine atom has seven valence electrons and electrons usually occur in pairs. Having seven valence electrons means that a chlorine atom has three pairs of electron and one unpaired electron in its outermost shell. The two chlorine atoms will combine together each donating its unpaired electron to be shared, thus leading the two atoms to attain stable octet structure of Argon.
<span>The process when you are carefully looking at an object or process is called an observation. The object is the primary source, from which with careful and active observation information is obtained. Observation can also include usage of instruments in order to collect the data.
Other term used for observation is monitoring. </span>
They are not made of cells and they cannot reproduce on their own.
Mitosis.
Asexual reproduction is the type of reproduction in which a cell make a copy of itself. In asexual reproduction there occurs simple cell division.No fertilization of egg and sperm can be seen in asexual reproduction. Thus in asexual reproduction offspring have identical genetic material as that of parent. Similarly in mitosis two identical nuclei are formed which are genetically identical to the nucleus of the parent cell.
