Question

1. which option describes the level of organization for a group of tissues? a. cell b. organ c. organism d. molecule 2. which of the following statements best summarizes the three processes that all cells undergo to maintain homeostasis? a. a cell must send out signals, hunt food, and release waste. b. a cell must develop its own food, form new cells, and move. c. a cell must release waste, breathe oxygen, and send out signals. d. a cell must break down food for energy, release waste, and form new cells.

Explanation:

Question 1:

The levels of biological organization are molecule, cell, tissue, organ, organ system, organism. A group of tissues forms an organ. So the option that describes the level of organization for a group of tissues is organ.

Homeostasis is the process by which cells (and organisms) maintain a stable internal environment. Cells need to break down food for energy (metabolism), release waste (excretion), and form new cells (cell division) to maintain homeostasis. Option A includes hunting which is not a universal cell process. Option B includes developing food (not a cell process) and moving (not all cells move). Option C includes breathing oxygen (not all cells use oxygen) and sending signals (not a core homeostasis process for all cells). Option D includes breaking down food for energy, releasing waste, and forming new cells, which are key processes for maintaining cell homeostasis.

Answer:

B. organ
