Explanation:
The function of the cell membrane is to protect the organelles that break down proteins and nutrients.
It is semi-permeable which means it takes in select nutrients and excretes cell waste into the bloodstream.
Gravity , Explosion
<u>Explanation:</u>
Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger.
Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star.

Answer:
Closed system.
Explanation:
Robot is an closed system because there is no transfer of mass but transfer of energy occurs from robot to its surrounding. According to the definition of closed system, closed system is a type of system in which there is only transfer of energy occurs while in open system both mass and energy can be transferred from the system to their surrounding. So no mass transferred from the robot only energy in the form of mechanical energy is transferred.
Answer:
The primary "food" produced by photosynthesis is a 6-carbon sugar called glucose.
Explanation:
Through photosynthesis, plants use the sunlight to create a sugar called glucose. The plants use this energy to create other substances, such as starch and cellulose. This gives them the nutrients and vitamins they need to grow.
Hope this helps! :)
