Answer:
Answer is D - cAMP.
Explanation:
cAMP is a small molecule that functions as an intracellular signaling molecule - a second messenger. The first messenger would be the thing that activated the GPCR (e.g. a hormone). The GPCR is a signal transducer (converts extracellular signal to intracellular signal). Once activated, the GPCR activates adenylate cyclase which can be called a signal effector - it is an enzyme that produces cAMP.
An autotroph is an organism capable photosynthesis or chemosynthesis through reducing carbon dioxide, fats, sugars and/or proteins in a repetitive cycle of energy production and use to support its life. these include all plants, algae and certain bacterium.
its counterpart is the heterotroph which is reliant on outside sources for their means of energy. aka tertiary consumer: animals, fungi and certain bacterium
Answer:
Explanation:
The temperature and pressure on the earth's surface is lower than that below the earth's surface. Generally, temperature and pressure increases as you move/dig down the earth's surface. This increase in temperature and pressure causes the earth's sediment (below the earth surface) to form a compact solid rock - this process is known as lithification.
Glacial evidence discovered in South America demonstrates how climate change evidence has bolstered the notion of continental drift. Folded mountains in Africa and South America. Thus, the correct option is D.
Climate change is happening all across the planet on a daily basis. This is primarily due to human activities that have had an impact on the atmosphere and the earth.
<h3>
What is continental drift?</h3>
Continental drift is basically the hypothesis that the continents once constituted a single landmass, disintegrated, and drifted to their current places.
The discovery of glacial evidence in South America has led to a greater acceptance of the continental drift idea.
Finally, we can conclude that glacial evidence discovered in South America demonstrates how climatic change evidence supports the hypothesis of continental drift.
