The cell membrane functions as a selective barrier. We call these kind of membranes as differentially permeable or semi permeable membrane. It can decide what substances can pass in and out. Therefore it can surround the cytoplasm (which is the inside of a cell) to separate the cell's content from the surroundings.
Answer: Y represents carbon and z is oxygen which gives CO2
Explanation: To photosynthesis to occur Carbon has to reacts with oxygen to give carbondioxide (Co2) which then combines with hydrogen (H2) and oxygen to give water (H20) the reaction gives glucose (C6H12O6).
Equation for photosynthesis = 6CO2+6H20- C6H12O6
Answer:
Most of its components are anatomically connected, like most other systems of the body.
Explanation:
The endocrine system takes care of the bodily processes that take place slowly. The nervous system and the endocrine system are independent systems, although they usually work together to help the body function properly.
The endocrine system is made up of glands that make hormones.
The main glands that make up the human endocrine system are the hypothalamus, pituitary, thyroid gland, parathyroid glands, adrenal glands, pineal gland, and reproductive glands, including the ovaries and testes. The pancreas is also part of this system and they are distributed throughout the body, connecting only through the circulatory system.
