Answer:
the answer to 32 would b option C cellulose
Within a protein, multiple amino acids are linked together by peptide bonds, causing them to form a long chain. its easy to remember by thinking of the amino acids hooking up like a trains cars.
CELL REPRODUCTON: many organelles are involved in cell reproduction, including the nucleus and the mitochondria and chloroplasts. All of these organelles contain DNA that must be replicated so that each new cell will have complete copies.
In order to move molecules against the concentration gradients, the cell must have the advantage of Creates energy
<u>Explanation:</u>
When a solute is concentrated to a particular area it is called as concentration gradient. The law of thermodynamics well explains that a molecule moves from area of higher concentration to lower concentration.
If a molecule moves against the concentration gradient it is called as Active transport. For this process to happen the cell needs to energy efficient.
Energy is been released and it is stored in the form of bonds between the atoms during active transport. To maintain the proper balance in the molecules and the balancing of ions active transport is essential.
<em>carbon has four valence electrons in its outermost shell .. which makes it able to form four bonds to complete its valence shell ..
it forms large number of chains with its own self which makes it useful .. also it forms bonds with oxygen and hydrogen forming large organic compounds of great importance ..</em>
