Question

1. which group of organisms consists of specialized cells? a. unicellular prokaryotes b. multicellular prokaryotes c. unicellular eukaryotes d. multicellular eukaryotes 18. how does specialization of cells contribute to maintaining homeostasis in multicellular organisms?

Explanation:

1. Specialized cells are found in multicellular organisms. Unicellular organisms are made up of a single cell and do not have cell - specialization in the same sense as multicellular organisms. Prokaryotes are generally single - celled and lack the complex cell specialization seen in multicellular eukaryotes. So the answer is d. multicellular eukaryotes as they have the most complex level of cell specialization.
2. In multicellular organisms, cell specialization allows different cells to perform specific functions. For example, nerve cells transmit electrical signals, and muscle cells contract. This division of labor helps maintain homeostasis. Different specialized cells work together to regulate internal conditions such as temperature, pH, and nutrient levels.

Answer:

1. d. multicellular eukaryotes
2. Specialized cells perform specific functions that contribute to maintaining internal conditions like temperature, pH, and nutrient levels, thus helping in maintaining homeostasis in multicellular organisms.
