Answer:
Temperature and pressure progressively increase with increased proximity to Earth's core. Recent studies indicate the core's temperature may be close to 11,000 degrees Fahrenheit; that's nearly 2,000 degrees warmer than previously thought and hotter than the surface of the Sun, according to a 2013 Forbes article.
Explanation:
<h2>(A) is the correct option </h2>
Explanation:
- An organism is part of a community is correct,where species interaction occurs between different organisms
- A community is part of population is the incorrect statement because a community includes group of population of two or more different species
- An ecosystem is made up of only organisms is the incorrect statement because ecosystem is the community of both living and non living components of the environment and how they interact with each other
- A biome is the biotic part of an ecosystem is incorrect because biome includes the community of both plants and animals occupying a large habitat
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.
Organism is the smallest unit of organization.
