It is the 3rd one Light Energy is transformed into chemical energy. Light being Sun
Answer:
Instead of cells, a non-living thing is made up of elements or compounds that form from chemical reactions. Examples of non-living things are rocks, water, and air.

Answer:
b. neither DNA replication nor transcription can occur, and the bacteria will probably die
Explanation:
Ultraviolet light (UV) is a powerful mutagenic agent that produces thymine dimers among contiguous base pairs. These dimers are highly stable, and thus DNA repair mechanisms are inefficient. UV light is particularly harmful to bacteria and viruses. It is for that reason that UV is used to sanitize by damaging such pathogens, avoiding them from multiplying and consequently also inhibiting transcription.
Answer:
The intestinal pH is a neutral pH, that is, 7.
If this pH is not met, it does not tend to neutralize the stomach enzymes will not be regulated, that is to say that when we digest the food bolus the gastric enzymes that are dumped together with the food in the form of chyme to the intestine are active because the low pH and the acidic medium is what triggers its action, when encountering intestinal neutrality that ranges from 5 to 8 in terms of pH, these enzymes are inactivated and stop working at the intestinal level, giving rise to the activation of intestinal juices.
Explanation:
https://pubmed.ncbi.nlm.nih.gov/21947475/ in this link I leave you a scientific evidence of pubmed associated with how intestinal pH is regulated through the mucus that is secreted in it and even how it is related to it bacterial growth of both commensal flora and other bacteria.
The intestinal pH is essential to be maintained since it regulates the immune system, the predominant commensal flora that protects us from serious opportunistic infections and the enzymatic activity that helps us assimilate nutrients, it is essential to note that in the intestine is where more absorption of Nutrients are fulfilled compared to the rest of the organs of the gastrointestinal tract.
