Answer: The sun sustains all life on earth through photosynthesis, the process by which plants and other organisms convert the energy of sunlight into chemical energy, stored in the bonds of organic molecules. A central challenge of modern science is to replicate this process using synthetic catalysts, and thus produce solar fuels by artificial photosynthesis.
Explanation:
Answer:
A
Explanation:
Because when particles move slower they start getting closer to one another, the attraction between them puls them toward each other.
Answer:
The answer is given below.
Explanation:
A tiny difference in a distant enhancer make a blond through DNA Looping.
DNA Looping can bring the enhancer bound by an activator physically closer to the promoter even if the enhancer is located far away along the DNA molecule.
DNA Looping.
When a protein or a set of complex proteins binds to 2 different sites of DNA simultaneously while looping out the interfering DNA.
Important of DNA Looping
- It regulates metabolism of DNA
- it is involved in transcriptional initiation of prokaryotic operons.
Because they are plant cells , animal cells are oval like with a rigid outer layer.A plant cell is the only cell out of plant and animal that has a cell wall+cell membrane
