Final answer:
The statement that both Bio4 and ProChondrix CR have living cells could be true, provided they are types of cellular grafts or biomedical products. Additionally, it is true that viruses can infect fungal cells, and some organisms are unicellular. Typically, ribosomes are found within the cytoplasm of a cell.
Step-by-step explanation:
The question poses a statement for validation regarding living cells in Bio4 and ProChondrix CR. It is essential to have background knowledge in biomedical materials and cell biology to answer accurately. In context, where the statement specifically mentions that both Bio4 and ProChondrix CR contain living cells, based on the presumption that these are types of cellular grafts or biomedical products which generally do contain living cells, the statement could be considered true. However, without specific reference to these products or further context, a definitive answer cannot be provided.
Additionally, viruses can indeed infect all domains of life, including fungi, so the statement that scientists have identified viruses that can infect fungal cells is true. Organisms can be unicellular, which means that the statement some organisms are made of only one cell is also true. Ribosomes are typically found within the cytoplasm, so to say ribosomes are found outside of the cytoplasm of a cell would be generally false, although there are exceptions, such as those associated with the endoplasmic reticulum.
