Answer:
a. Cell wall and chloroplasts
Explanation:
The cell wall in plants facilitates the retention of the cell shape during over-hydration. The chloroplasts are organelles in plants that carry-out photosynthesis and produce glucose.
Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
We breath in oxygen and out carbon dioxide where plants breath in carbon dioxide and out oxygen. that is how we are alike when it comes to energy and like plants it takes time for us to grow.
hope this helps
The answer is C, because it has a negative charge -1. All groups with charges called ions, unless they are organic compounds.
