Here are the answers to your questions: 8. Plants are able to accumulate most of their waste products for long because many of these products are not toxic to the plant in the concentrations they are stored, or they are stored in inactive forms or isolated compartments like vacuoles, dead cells (e.g., heartwood), or bark. 9. Three methods used by plants to excrete their waste products are: Transpiration*: Release of water vapor and some dissolved wastes through stomata. Shedding of leaves, bark, or fruits*: Waste products are accumulated in these parts and removed when they fall off. Storage in vacuoles*: Many waste products are stored in the large central vacuole of plant cells. 10. The conditions in human beings that result in the following: i) Production of large quantities of dilute urine: Occurs when the body has excess water or low levels of Antidiuretic Hormone (ADH)*. ii) Release of aldosterone hormone: Occurs in response to low blood pressure, low blood volume, or high potassium levels*. iii) Release of glucagon hormone: Occurs when blood glucose levels are low*. 11. The class in the phylum Arthropoda which has the largest number of individuals is Insecta. 12. Two characteristics of fungi are: They are heterotrophic*, obtaining nutrients by absorption. Their cell walls are made of chitin*. 13. To determine if a urine sample was obtained from a person suffering from diabetes mellitus, you would carry out a Benedict's test. Test: Benedict's test for reducing sugars (glucose). Procedure: Add Benedict's reagent to the urine sample and heat it gently. Result for diabetes mellitus: A color change from blue to green, yellow, orange, or brick-red precipitate indicates the presence of glucose, which is characteristic of diabetes mellitus. 14. Classification of a housefly: Kingdom: Animalia* Phylum: Arthropoda* Class: Insecta* 15. During thermoregulation, the changes that occur in arterioles in the human skin are: Vasodilation: When the body is hot, arterioles widen* to increase blood flow to the skin surface, allowing more heat to be lost by radiation and convection. Vasoconstriction: When the body is cold, arterioles narrow* to reduce blood flow to the skin surface, thereby conserving heat. 16. Giving a reason in each case, the class to which each of the following organisms belong: Bean plant - Class: Dicotyledoneae* (or Magnoliopsida) Reason: It has two cotyledons in its seed, net-veined leaves, and a taproot system*. Bat - Class: Mammalia* Reason: It possesses mammary glands (produces milk), has hair or fur, is warm-blooded, and gives live birth*. Send me the next one 📸
