They lower the activation energy. The energy needed for a reaction to occur.
<span>ANSWER: lowering the amount of energy required.

BTW. The enzyme is a ferment conducting chemical reactions in living organisms. Each enzyme catalyzes a chemical reaction strictly defined for a specific substrate and conditions.
Answer:
Sonic Hedgehog.
Explanation:
Sonic hedgehog is a secreted protein that in humans is encoded by the SHH gene. It is the best studied ligand of the hedgehog signaling pathway, others being desert hedgehog (DHH) and Indian hedgehog (IHH). It plays a key role in the development of animals, from insects to mammals. In vertebrates, it is involved in organogenesis, including the growth of digits on limbs and the organization of the brain.
Sonic hedgehog has also been shown to act as an axonal guidance cue. It has been demonstrated that SHH attracts commissural axons at the ventral midline of the developing spinal cord. Specifically, SHH attracts retinal ganglion cell (RGC) axons at low concentrations and repels them at higher concentrations
Answer:
Bacteria can have one flagellum or several.
<u>Condensation</u> is the next step in the water cycle that is most likely to happen next as water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. and as the molecules travel away from the equator.
Explanation:
As the warmer air mass rises into the upper atmosphere, at the equator, it begins to cool because temperatures drop with altitude. The relative humidity of the air mass increases until it reachesdew point. The water vapor begins to condense into water droplets.
This air mass begins moving towards the poles (away from the equator) bringing with it clouds (condensed water vapor) that precipitate later on. This air mass begins to sinks because it has become denser with a decrease in temperature. As it sinks it replaces the air mass moving to the equator. The air rushing to the equator is replacing the rising warm air mass at the equator. This cycle continues.
