1. True: asexual allows for rapid reproduction
2. False: increases genetic variation in a population
3. False: sexual reproduction creates more genetic variation
4. True: during meiosis, the genes can combine differently. See punnet squares and genetics (Mendel's pea study)
<u>Answer:</u>
<em>Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk.
</em>
<u>Explanation:</u>
<em>The leaves of touch me not plant stay upright due to turgor pressure. </em>It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.
When there is an external disturbance , parts of the plant releases certain chemicals including potassium ions that causes water to diffuse out of cells. <em>This releases the turgor pressure and causes the leaves to shrink. </em>

Answer: This is What drives ocean currents
- Surface is primarily driven by wind (friction from wind transfers energy and momentum to surface water)
- Deep is slower, driven primarily by density (salinity and temperature) differences
- Thermocline: dramatic temp drop 50 m from surface bc sun can't shine
- Halocline: dramatic gradient in saline, increase as it deepens
- Pycnocline: resulting change in density (50-1000)
