The answer is option C. Number of double covalent bonds between carbon atoms is responsible for causing different shapes of saturated and unsaturated fatty acids. The double covalent bond causes kink in the unsaturated fatty acids because of which their stacking is disrupted and they become loosely packed. The problem with double covalent bond is that unlike single covalent bond it can't rotate and has almost cis-configuration. This is also the reason behind their liquidity at room temperature.
A. Computers were discovered in 1822

Answer:
Renewable resources make cleaner energy. It takes longer to replenish renewable resources. Renewable resources are more easily located and harvested. It often costs much less to produce energy from renewable resources.
Photosynthesis takes place<span> inside plant cells in small things called chloroplasts. Chloroplasts (mostly found in the mesophyll layer) contain a green substance called chlorophyll. Below are the other parts of the cell that work with the chloroplast to make </span>photosynthesis happen<span>.</span>
