Answer:
B) Tissue is made of different types of cells.
D) Organs are made of different types of tissue.
Explanation:
The tissues are made of different types of cells. The organs are also made of different types of tissue. There is no need of same types of tissues to make organs. Thus, option (B) and (D) is correct answer.
Answer: Respiratory system, Excretory system, and Endocrine system.
Explanation:
Homeostasis is the process through which several organ systems work to maintain a stable internal environment in the body. There are three organs of the body which ar eaccurately maintained by homeostasis:
Respiratory system: High carbon dioxide content in the blood triggers faster breathing. Most frequently, the lungs exhale, which quicker extracts carbon dioxide from the body.
Endocrine system: High blood sugar content causes insulin release by an endocrine gland called pancreas. Insulin is a hormone which helps the cells absorb blood sugar.
Excretory system: A low blood level of water causes kidney accumulation of water. The kidneys contain more concentrated urine, so less water from the body is lost.
Hence, three critical areas are respiratory system, excretory system, and endocrine system that are accurately maintained by homeostasis.
