Answer:
1. Archaeplastida.
2. Excavata.
3. Amoebozaons.
4. Stramenopiles.
5. Rhizarians.
6. Alveolates.
Explanation:
Protists can be defined as any group of eukaryotic organisms that belongs to the kingdom protista and are not plant, animal or fungus.
These are the six (6) groups of protists;
A. <u>Archaeplastida</u>: have a cell wall and both an outer and an inner membrane. There are no membraneous organelles in this group.
B. <u>Excavata</u>: have a feeding groove on one side and are usually single-celled. Members include organisms with heterotrophic, photosynthetic, parasitic, or symbiotic lifestyles.
C. <u>Amoebozaons</u>: use pseudopodia to move and may be either single-celled or multicellular. Members within this group exhibit free-living and parasitic lifestyles.
D. <u>Stramenopiles</u>: have a tinsel flagellum and are photosynthetic.
E. <u>Rhizarians</u>: have elaborate tests composed of calcium carbonate, silicon, or strontium salts. Members have thin pseudopodia that project from the test.
F. <u>Alveolates</u>: have membrane-enclosed sacs beneath the plasma membrane. There are photosynthetic and heterotrophic members in this group.
There are no true tropic climates
A single motor neuron together with all the skeletal muscle fibers it innervates is called a motor unit.
- Motor neurons are more than just relays for the motor commands sent down the hierarchy from higher levels. They themselves are parts of intricate circuits that carry out extensive information processing.
- Due to their highly branching, intricate dendritic trees, motor neurons are able to integrate inputs from several other neurons and generate accurate outputs.
- A single motor neuron, and nothing else, innervates each and every muscle fiber (make sure you understand the difference between a muscle and a muscle fiber). However, several muscle fibers can be innervated by a single motor neuron.
- A motor unit is the aggregate of a single motor neuron and all of the muscle fibers that it innervates. The innervation ratio refers to how many fibers a motor unit innervates.

Answer:
Anabolism
Explanation:
metabolism is the breakdown of complex molecules.
catabolism is the breaking down or building up of complex molecules in the body. Metabolism and Anabolism are both subsets of catabolism.
Answer: Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.
