The correct answer is A - leaves that close when touched.
The Venus flytrap is a type of flowering plant that is best known for its unique adaptation to trap live insects using a trap.
The trap is made up of two hinged lobes at the end of each leaf, with hair like projections called trichomes that cause the lobes to snap shut when prey comes into contact with them.
This type of movement is called thigmonasty which is a non directional plant response to being touched.
They say how an enzyme perfectly fits into its substrate is alike a "lock and key".
Only one specific enzyme can fit a specific substrate.
<span>Metamorphic rocks form by existing rocks join together under high heat and pressure. Examples of metamorphic rocks are marble, schist, slate, and quartzite. Metamorphic rocks formed when the minerals are chemically changed due to heat and pressure. They are often seen near magma but they do not melt like igneous rock.</span>
Fatty acids
fatty acid synthesis is the formation of fatty acid from acetyl coa and NADPH with help of the enzyme known as fatty acid synthases. This reaction occurs inside the cytoplasm of the cell. The fatty acids that were formed were derived from carbohydrates via glycolytic pathway. This pathway can also give glycerol which is different form fatty acids
I would say an "Altitude Tint Map" or a "Mercator Projection Map".
Hope this helped!
