Unicellular organisms cannot achieve this large size. What limitsunicellular growth? How do multicellular animals solve this problem? pelase do not copy from google
- Endothermic homeotherms, like mammals, maintain a high internal body temperature, whereas ectothermic poikilotherms, like some reptiles, have internal body temperatures that fluctuate depending on the ambient temperature of their environment. Based on their metabolism, why might mammals have determinate growth whereas some reptiles have indeterminate growth?hydra Most animals have a(n) system to deliver and nutrients to cells. gastrovascular cavity foot Such systems also take and wastes away from cells. carbon dioxide In each cell is exposed to water and can independently digestive exchange gases, carry out digestion, or eliminate wastes. охудen The cells of the hydra use to pass nutrient molecules to ions other cells. circulatory In contrast, planaria possess a trilobed throughout the body to allow for diffusion of molecules between cells. that branches diffusionImagine that you are working in a pharmaceutical lab testing the effects of novel compounds on immune cells called macrophages. You discover one that causes an increase in the size and extension of the pseudopods that initiate amoeboid cell movement. This compound most likely: Inhibits tubulin's catalytic activity Increases tubulin's catalytic activity Inhibits actin's catalytic activity Increases actin's catalytic activity
