Respiration is the chemical reaction that break down nutrient molecules in living cells to release energy .
in humans and other living organisms except plants, our cells need energy ATP for muscle contraction and for cell division to repair damaged tissues and growth ,also for active transport which involves movement of molecules across a cell membrane against a concentration gradient.
Answer:
The endocrine system is a chemical messaging network. Endocrine glands secrete hormones, which are carried by the circulatory system throughout the body. The primary endocrine glands are the pituitary, hypothalamus, pineal gland, thyroid, parathyroid, adrenal, pancreas, ovary, and testis. Hormones maintain homeostasis in the body.

Hope this helps!
Im pretty sure its either, Ecosystem or Niche!
Answer:
B) sugars; leaf; apical meristem
Explanation:
Phloem is one of the vascular tissues and is mainly involved in the transport of sugars. Phloem sap is the aqueous solution that moves through sieve tubes of phloem. Phloem sap mainly consists of sugars but also carries amino acids, hormones, and minerals. Sucrose is the most prevalent sugar.
Phloem sap moves from sites of sugar production (called sugar sources) to sites of sugar use or storage (called sugar sinks). A sugar sink is an organ that either uses the sugars for energy production and other functions or stores it.
In late spring, the fully grown leaves serve as a source of sugars. Apical meristem is responsible for the growth of stem and root length and serves as a sugar source as it obtains sugars from the leaves and uses them during the growth of shoot and roots.
The best way to avoid measurement error in an experiment is being shown in the option C. instrument precision which means that a tool is controlled very carefully in order to get the most accurate result, and the answer for your question is D. misreading the instrument as it is an opposite of what I have just said.
