Answer:
The stages of the moon
Explanation:
The term menstruation is related to the moon stages. Because of their coincidence in occurrence and in their duration time, people used to associate the feminine cycle to the moon cycle.
It is commonly said that the ovulation stage coincides with the full moon stage. In the same way, menstruation occurs when there is a new moon.
What really occurs is that the feminine period might or might not coincides with the moon cycle, and depends on each woman. But this is not a strict rule.
The duration of a woman´s cycle depends on every woman, on the raze, on the age, among many other factors. The fact that sometimes the feminine cycle coincides with the moon cycle, does not mean that the moon determines the cycle stages in a woman.
Lana concludes that all of the deer in a forest are members of the same (geosphere / ecosystem / species / hydrosphere) because they look alike and breed with one another. She observes how the deer (population / community / ecosystem / biosphere) interacts with trees, wolves, and other living things of the forest (population / community / species / geosphere).
Answer:
1. Species
2. population
3. community

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.
