Answer:
C.
Explanation:
In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Replication of the nucleus.
4. Cinder cones are a volcano
Answer:
The correct pair is A: "apicomplexans—parasites of animals"
Explanation:
- Euglenophyta is a group of unicellular, eukaryotic organisms. They are small, free-living forms, or parasites that present different feeding mechanisms and behaviors, such as heterotrophy, autotrophy, or mixotrophy.
- Dinoflagellates are unicellular, flagellated, free-living protists that might form colonies. Most of them are autotrophic organisms but some of them are heterotrophic, or mixotrophic. In these last cases, dinoflagellates can feed on other dinoflagellates, protozoans, or diatoms. They can also be parasites.
- Entamoebas are endoparasitic organisms with no mitochondria as an adaptation of living in environments with low oxygen concentration.
- Apicomplexa is a unicellular, protist group. They have medical and economic importance as they are<u> animals</u> and human parasites. They have an apical complex that helps them to fixate to the host cell and release a substance that provokes an invagination in the host membrane. This invagination allows the parasite to get into the host cell.
