Answer:
A). Placenta
Explanation:
During pregnancy, the embryo formed as a result of zygote growth produced from fertilization is implanted in the UTERUS or WOMB of the female. The developing fetus is strictly dependent on the mother for all the substances it needs to survive. These substances reach the fetus via a structure present in the uterus. This structure is called PLACENTA.
Placenta is the connection between the mother and the developing fetus. It is an organ that helps the mother supply required nutrients and oxygen via the umbilical cord to the fetus. It also helps remove waste products from the fetus into the mother's blood. Hence, the PLACENTA is the site of nutrient and gas exchange (oxygen and CO2) between the mother and the fetus.

The right answer is Ribosomes
The ribosome is a complex composed of RNA and ribosomal proteins, associated with a membrane (in the granular endoplasmic reticulum) or free in the cytoplasm. Common to all cells (prokaryotes and eukaryotes), the ribosome (and especially its composition) varies according to the organisms, even if it is always composed of two distinct subunits.
The ribosome is a huge ribonucleoprotein complex that allows the translation of mRNAs into proteins.
The organelle responsible for protein assembly is the ribosome. It exists either freely in the cytoplasm or attached to the rough endoplasmic reticulum, which also plays a role in protein modification. The Golgi apparatus further modifies and packages proteins, while the nuclear envelope regulates flow of substances.
Out of the organelles you listed: ribosomes, the Golgi apparatus, the nuclear envelope and the endoplasmic reticulum, it is the ribosomes that are responsible for protein synthesis. Ribosomes can either be found freely in the cell cytoplasm or attached to the endoplasmic reticulum (ER), forming what is known as the rough endoplasmic reticulum (RER). The ER, specifically the RER, plays a role in further modification of proteins. Meanwhile, the Golgi apparatus is involved in further protein modification and packaging, and the nuclear envelope acts as a barrier between the nucleus and the cytoplasm, controlling the flow of substances in and out of the nucleus.

B. maintain a balance of power.
C. put a conscription system in place.
D. end the spirit of militarism.
The correct answer is option B) Maintain a balance of power.
I just did the exam, good luck guys <3
The Answer is B because if we just look at the moles of nitrogen and oxygen they are in the ratio of 1:2. Since there are 3 moles with it, Even if we when we multiply this ratio by 3 the answer will be 3:6 and 6 is the double of 3 so B is the answer

Explanation:
Osmosis is the movement of water through a semipermeable membrane from high to low concentration. It is driven by the imbalance in water concentration and facilitated by aquaporins. Osmosis plays a crucial role in the functioning of red blood cells and the kidneys.
Osmosis is the movement of water through a semipermeable membrane according to the water's concentration gradient across the membrane, which is inversely proportional to the solutes' concentration. While diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the solutes' diffusion in the water. Not surprisingly, the aquaporins that facilitate water movement play a large role in osmosis, most prominently in red blood cells and the membranes of kidney tubules.
