Answer:
The correct option is d.
Unicellular and simple multicellular organisms isolate and eliminate waste materials by: <u>moving the wastes into a contractile vacuole and eliminating them through exocytosis.</u>
Explanation:
In all living systems, from prokaryotes to more complex multicellular eukaryotes, the regulation of substance exchange with the inanimate world occurs at the level of the individual cell and is performed by the cell membrane. The cell membrane regulates the passage of materials into and out of the cell, a function that makes it possible for the cell to maintain its structural and functional integrity. This regulation depends on interactions between the membrane and the materials that pass through it. Non-assimilable substances accumulate in vacuoles or fuse with the plasma membrane, and exocytosis expels their contents.
Exocytosis is an inverse process of endocytosis, in which an intracellular vesicle approaches the plasma membrane fusing with it so that the content of said vesicle is poured into the extracellular environment. By exocytosis, the cell can expel the remains of the cell digestion process that are not useful to it and also the secretion products from the Golgi apparatus in the form of secretory vesicles. If too much water enters the cell, it could dilute the cell contents to the point of interfering with biological functions and could eventually break the cell membrane. In the Paramecium, there is a specialized organelle, the contractile vacuole, which prevents this from happening since it collects water from various parts of the cell and pumps it out with rhythmic contractions.
Mendel concluded that pea traits like flower color were determined by separate units. From the results, Mendel proved that all traits do not blend. For instance, purple flowers mixed with white flowers did not produce pink flowers.
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. ... This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.
Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
Mendel's Results
Mendel noted the ratio of white flowered plants to purple-flowered plants was about 3:1. That is, for every three purple-flowered plants, there was one white flowered plant.

The nurse must assess the patient's pain intensity before and after administering an opioid analgesic. The respiratory rate and level of consciousness need to be assessed because respiratory depression and sedation are two adverse effects of opioid analgesics. Seizure activity, electrolytes, liver function, blood glucose level, and mental status may need to be assessed during opioid analgesic therapy <span>related to adverse effects. Correct answer:)</span>
