melisa1 [442]
<span>It's because the process is not as organized as we have learned it. We tend to think of intracellular reactions as they're supposed to work. Only thymine is supposed to bond to adenine. Only a specific type of ligand bonds to a certain receptor etc. this type of thinking leaves it hard to imagine what's actually going on. Imagine complete and utter chaos. Enzyme being hit by all the wrong and right molecules many many times per second. Molecules flying off in every which direction and hitting against anything and everything. When we learn about these reactions we tend to think it's ordered based on how specific things are. Not only is an enzyme/protein site made to fit only a specific molecule, it has to be the correct orientation. So even if the right molecules are in the right place hitting against the right enzyme does not mean it will attach, assuming it doesn't approach at the right angle.</span>

earths climate systems are driven by the electromagnetic radiation from the sun, as well as its reflection, absorption, storage
AleksAgata [21]

Answer:

True

Explanation:

Earth's radiation, that is, the energy that comes from the reflection, absorption, storage, and distribution from the Sun among the spheres play a major role in the climate systems.

The ultraviolet and visible energies from the Sun are the main drivers of the Earth's climate systems as the interaction between the particles of aerosol that are present in the atmosphere and the radiation from the Sun lead to the warming of the atmosphere.

Therefore, the answer is True.

Arrange the following steps to explain the process of protein synthesis inside the eukaryotic cell.
WITCHER [35]

Answer:

Ribosomes are produced inside the nucleus, by the nucleus, then leave the nucleus through nuclear pores

Some ribosomes attach to ER whereas others move freely in cytoplasm

Ribosomes use mRNA to make proteins

Ribosomes synthesis proteins that are then placed in vesicles (sacs)

Proteins then move to the golgi apparatus where they get folded and carbohydrates and lipids attached to them

Fully active proteins leave the cell through cell membrane
