<span>The genome of the E. coli bacteria is very crisp and simple with only 4400 genes, easy to study and understand. The ability of the bacteria to multiply drastically producing a generation in 1200 seconds under suitable growth condition dragged the attention of the researchers. Coming to the safety in handling the organisms, except for the particular harmful strain (O157:H7), the normal organism from the flora of the gut is safe to handle under suitable microbiological environment. The first completely sequenced genome is an additional feather in the cap of E. coli making the bacteria easier to use in recombinant DNA technology which involves nothing but the ultimate expression of proteins. Also the competence of the E. coli bacteria as a host for foreign DNAs and simple laboratory procedure to cultivate and adaptability to both aerobic and anaerobic environment made the E. coli bacteria a pioneer in the field of biotechnology.</span>

What is true about cellular respiration and 2 facts about photosynthesis and cellular respiration
makvit [3.9K]

Answer:

* The glucose needed for Cellular respiration is delivered by plants. Plants experience a process known as photosynthesis.

* Photosynthesis can be considered as the contrary process of Cellular respiration. Through two processes known as the light reactions and the dark reactions, plants can assimilate and use the energy in daylight. This energy is then changed over alongside water and carbon dioxide from the environment into glucose and oxygen.

* Since this is the contrary process of Cellular respiration, plants and animals are said to have a cooperative relationship. This implies that plants and animals live respectively and advantage from one another.

Explanation:

Cellular respiration is the process by which the substance energy of "food" particles is delivered and incompletely caught as ATP. Starches, fats, and proteins would all be able to be utilized as fills in cellular respiration, yet glucose is most normally utilized as an illustration to analyze the responses and pathways included.

Which element is most likely to be a nonreactive gas?
aniked [119]

Answer:

Xe

Explanation:

Cs and Na are solids in room temperature while F and Xe are gases.

The number of electrons in the outermost shell of an atom will determine its reactivity. Out of the gases given Xe and F, F ( the most electronegative element) posses 5 valence shell electrons which makes it highly reactive while Xe which is a noble gas posses 8 valence shell electrons which makes it less reactive compared to many elements.
