Carbon dioxide (CO²) is taken in to start the Calvin Cycle.
<h2>Answer is option "1 B & 2 C"</h2>
Explanation:
- Evolution genetics is a field of science, which includes the study of genetic variations that lead to evolutionary changes in organisms
- As some bacteria had changed their DNA that led to the development of antibiotic resistance in them
- Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
- Hence, the right answer is option 1 B and 2 C " evolution Genetics & less bacteria becoming resistant to the specific antibiotics"
Respiration using oxygen to break down food molecules is called aerobic respiration. 'Aero' means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate. Glucose is oxidised to release its energy, which is then stored in ATP molecules.
The word equation for aerobic respiration is:
glucose + oxygen → carbon dioxide + water (+ ATP made)
You need to be able to recognise the chemical formulas:
C6H12O6 + 6O2 → 6CO2 + 6H2O
<span>b. photosynthetic organisms provide energy for other organisms on earth.
B is the most suitable answer as photosynthetic organisms get their energy from the sun, and other organisms get their energy from photosynthetic organisms, so the sun is the source of energy for all life.</span>
