Question

question 1
what are the three main ways that protists can move?

question 2
the organisms that push carbon to the bottom of the ocean are known as what? why is this important to the ecosystem?

question 3
how is the endosymbiotic theory used to support the emergence of eukaryota?

Explanation:

Question 1: Protists can move using flagella (whip - like structures for propulsion), cilia (hair - like structures that beat in unison for movement), and pseudopodia (false feet, extensions of the cell membrane for crawling).
Question 2: Phytoplankton are organisms that push carbon to the bottom of the ocean through the biological carbon pump. This is important as it helps regulate the amount of carbon dioxide in the atmosphere, reducing the greenhouse effect and influencing climate.
Question 3: The endosymbiotic theory suggests that mitochondria and chloroplasts were once free - living prokaryotes that were engulfed by a larger cell. These endosymbionts provided energy (mitochondria) and the ability to perform photosynthesis (chloroplasts) to the host cell, leading to the emergence of more complex eukaryotic cells.

Answer:

Question 1: Flagella, cilia, pseudopodia.
Question 2: Phytoplankton; Helps regulate atmospheric carbon dioxide and influence climate.
Question 3: Suggests mitochondria and chloroplasts were once free - living prokaryotes engulfed by a larger cell, providing energy and photosynthetic ability for the emergence of eukaryotes.
