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.
Answer:
The majority of the cell membrane is made from phospholipids and has 2 layers
Answer:
2 moles of F
Explanation:
for every molecule of CaF2, without the two atoms of F, CaF2 cannot be formed.
Now we multiply both CaF2 and F by 6.02 X 10^23 to convert CaF2 and F to moles, it will be the same ratio since we multiplied both by the same number
Answer:
Taxol induces the assembly of microtubules, while Nocodazole suppresses tubulin assembly
Explanation:
Taxol and nocodazole are antimitotic drugs, i.e., drugs that inhibit the progression through the cell cycle, which is useful for killing cancer cells. Microtubules are proteins that act as the 'skeleton of the cell', which need to be reorganized when cells replicate. These structures (microtubules) are composed of α and β-tubulin heterodimers which assemble into protofilaments of microtubules. Taxol is an antimitotic drug that induces the formation of microtubules, thereby inhibiting microtubules' reorganization during mitosis. In consequence, cells treated with Taxol enter into apoptosis (i.e., programmed cell death). Moreover, Nocodazole is known to induce microtubule disassembly by interfering with the polymerization of tubulin monomers. In consequence, Nocodazole is useful to depolymerize the microtubule cytoskeleton.
