A)Antibiotics can always be used to treat bacterial infections.
Ratling [72]3 years ago
4 0

         The right option right here is option A. Antibiotics can always be used to treat bacterial infections.

         What happens here is, the use of antibiotics started with Alexander Fleming, a scientist who discovered penicillin, an antibiotic so strong that it could cure a lot of bacterial diseases during that time. But what he didn't know is that bacterias can adapt themselves, developing in this way a protection against this antibiotic, that's why nowadays we have superbacteria, this kind has lots of protections in its genes that we can't almost fight them with our medicine. Some antibiotics do a very good job at destroying bacterial cell wall , thats how some of them work.

Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.
Effectus [21]

<u>Answer:</u>

<em>Enzyme activity decrease at these temperatures. </em>

<u>Explanation:</u>

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions.  In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH. </em>

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.

<em>At a temperature above 38°c and below  0°c enzyme activity decreases. </em>

Sunflowers require soil and plenty of sunlight and water to grow and thrive.
kirill115 [55]
If asking true or false then true, if asking you to reword it then it is worded "sunflowers need sun and water to grow" if asking you to say the inverse say "if sunflowers do not have sun and water, they will not grow and thrive". I'm not sure what your asking though.
