That’s very simple uranium I believe but I haven’t done science class in like 7 years so don’t quote if I’m wrong
Answer:
The correct answer is diaphragm.
Explanation:
One of the barrier methods of controlling birth is the diaphragm. It is abstemiously efficient, with a one-year failure rate of approximately 12 percent with the typical application. It is positioned over the cervix with spermicide prior to having sex and is left in position for about 6 hours post-sex.
It is a rubber barrier that holds the spermicide against the cervix. The spring in the diaphragm's rim produces a seal against the walls of the vagina. The diaphragm covers the cervix and physically inhibits sperm from getting inside the uterus via the internal orifice of the uterus. Basically, the diaphragm has an application with spermicide, and it is broadly considered that the spermicide substantially enhances the efficacy of the diaphragm.
If the environment changes quickly and no individual members of a species are able to survive in the new environment, then the species will become extinct in that environment
Adam Smith described self-interest and competition in a market economy as the "invisible hand" that guides the economy. This episode of the Economic Lowdown Podcast Series explains these concepts and their importance to our understanding of the economic system.
