Answer:
These answers are A and C
Answer:
Before the antibiotic, the ‘good’ bacteria had colonized her intestines and formed colonies that made up her biome. These colonies out-compete other bacteria, including ‘bad’ bacteria that tried to grow in the intestines hence protecting her intestines from infection.
However, the antibiotics wiped out the established colonies of ‘good’ bacteria –destroying her biome- and gave room for recolonization of the intestines by bacteria. The secondary succession gave a chance for the ‘bad’ bacteria to also thrive and cause her massive infections.
Answer:
They are all involved in mechanical digestion.
- They are all accessory structures.
- They all digest carbohydrates.
- They all release digesting enzymes

Answer: Polyphyletic
Explanation: The kingdom Protista is considered Polyphyletic because their taxa do not share a common descendant that is many are developed by from many ancestral lineage. Protists are difficult to classify. They may be unicellular, colonial or multicellular. Polyphyletic groups mess up organizational systems.
As eukaryotes, protists can have many diverse organelles which includes a nucleus, mitochondria, contractile vacuoles, eyespots, plastids, pellicles, and flagella. The protists nuclei consist of chromosomes, with DNA linked with proteins. Protists can undergo sexual and asexual reproduction, meiosis, and mitosis. Protists can be free-living, or live symbiotically with another organism. This symbiosis can be mutual or parasitic. Many protists are economically beneficial to humans, while several others can cause fatal diseases. Protists make up the most of the planktons in aquatic life, where they areas the primary producer of the food chain. Many protists are motile using cilia, flagella, or pseudopodia (false feet) to move, while others are sessile( non-motile). They may be producing their own food from sunlight (autotrophs) or using a outside source of nutrition from outside (heterotrophs) . Researchers are currently comparing the RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) sequences of the protists with that of plants and animals, but no conclusive evidence has been reached. It is unknown to many researchers whether protists were the precursors to plants, animals or fungi or bacteria.
