Hi there! The answer should be B. Chloroplasts contain chlorophyll which allows the plant to undergo photosynthesis, and this allows the plant to make its own food. Hope this helps you!
Every organism has a unique ecosystem within which it lives. This ecosystem is its natural habitat. This is where the basic needs of the organism to survive are met: food, water, shelter from the weather and place to breed its young. All organisms need to adapt to their habitat to be able to survive.
Blade
Thin, flattened section of a plant leaf that collects sunlight
Petiole
Thin stalk by which a leaf blade is attached to a stem
Mesophyll
Specialized ground tissue that makes up the bulk of most leaves; performs most of a plant's photosynthesis
Palisade Mesophyll
Layer of tall, column-shaped mesophyll cells just under the upper epidermis of a leaf
Spongy Mesophyll
Loose tissue beneath the palisade layer of a leaf
Stoma
Opening in the underside of a leaf that allows carbon dioxide and oxygen to diffuse into and out of the leaf
Guard Cell
Specialized cell in the epidermis of plants that controls the opening and closing of stomata by responding to changes in water pressure
Transpiration
Loss of water from a plant through its leaves

<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"
