I believe the best answer is A.
People are more afraid in fossil fuels running out rather than the other reasons that don't really affect the people today. Hope it helped!!!
Bats and birds are unrelated animals, yet they both evolved wings. by acquiring similar traits (i.e., wings) as they adapted to similar environments, these species exhibit convergent evolution through analogy present between the wings. Convergent evolution happens when two distantly related organisms acquire the similar traits in response to the similar habitat or niche.
Answer:
- Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
- Algae → would have survived without this food source → Heterotrophs
Explanation:
The protist kingdom is composed of two main groups. The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.
- Algaes are autotroph
- Protozoans are heterotroph
<u>Protozoans</u>:
Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on<u> bacteria</u>, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.
<u>Algae</u>:
Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.
Answer:
120 centimeters equals 1.2 meters
Answer:
Insulin
Explanation:
Not sure how to explain this further, as the function of the enzyme is explained fully in the problem lol. PM me if you want more details though!
