A. reduced water or food intake
B. infectious organisms
C. elevated or depressed blood pH
D. extreme temperatures.
Homeostasis, the body's ability to maintain internal balance, can be challenged by reduced food or water intake, infectious organisms, changes in blood pH, and extreme temperatures. These challenges can disrupt the body's normal functions and cause varying health impacts.
The body's ability to maintain a relatively constant internal environment, called homeostasis, can indeed be challenged by various factors. Reduced water or food intake can alter the balance of nutrients and hydration in the body, potentially leading to dehydration or malnutrition. Similarly, infectious organisms such as bacteria, viruses, or parasites can disrupt homeostasis by causing disease.
Elevated or depressed blood pH, which refers to the acidity or alkalinity of the blood, can disrupt bodily functions if it falls outside of a certain range. Finally, extreme temperatures can challenge body's ability to regulate its own temperature, potentially leading to conditions like hypothermia or heat stroke.

Answer:
False
Explanation:
The first living thing on planet earth was a single celled species commonly termed as prokaryotic. These simplest forms of species were made up of primordial chemicals which some how under specific environmental condition developed into proteins and RNAs thereby generating higher forms of life. The earliest form of single celled prokaryotes were termed as bacteria and archae. These tiny creature were observed for the first time some 4 billion years ago.

The correct answer is endocrine system.
Endocrine system in vertebrates consists of endocrine glands. Endocrine glands do not have ducts thus, they are also called as ductless glands. The glands which secretes enzymes are glands with duct, called exocrine glands. Therefore, the hormones secreted from endocrine glands are directly poured into the blood for the action on target organs. Examples of endocrine glands are pituitary gland, thyroid gland, adrenal gland.
