Answer:
Oxygen for respiration and Carbon dioxide for photosynthesis
Explanation:
Answer:
The correct answer is the letter b. The endosymbiotic event that brought chloroplasts into Eukaryotic cells actually happened after Eukaryotic lineages diverged so many lineages never actually possessed chloroplasts
Explanation:
The plastid is an organelle linked to membarna found in the cells of eukaryotic organisms, which contains pigments used in photosynthesis. Some eukaryotic organisms over time have inherited the ability to photosynthesize from cyanobacteria by secondary endosymbiosis or ingestion, and are able to capture and sequester photosynthetic cells and chloroplasts, this process is known as kleptoplasty.
The answer is; C
A PET scan is a positron emission tomography used to image the inside of the body. It involves the ingestion of a radioactive element. The element is actively absorbed by the tissue with active cellular activity hence these areas will show as bright spots when the body (this case the brain) is scanned.
