Whether or not the fatty acid has double or single covalent bonds
a fatty acid is saturated when only single bonds to H hold it together
a fatty acid is unsaturated when a double bond helps hold it together, this type of fatty acid becomes bent as a result

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
<span>Option 1: Sunlight is the energy source for plant photosynthesis.
True: In photosynthesis, plants convert light energy from the sun to chemical energy in the form of glucose.
Option 2: Chlorophyll is contained in organelles called chloroplasts.
True: Chlorophyll in the chloroplasts is what allows many wavelengths of light for be absorbed and used for photosynthesis.
Option 3: A by-product of photosynthesis is carbon dioxide.
False: Plants require carbon dioxide to create glucose, and produce oxygen as a by-product.
Option 4: Roots have tiny root hairs that maximize the plant's ability to absorb water.
True: Root hairs are very important for the absorption of nutrients and water by plant roots. </span><span /><span>

Answer:
Plant Parts - Flowers
The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style.
