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.

Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Proximal convoluted tubule cells. As well as the epithelial cells along the renal tubule and the duct. Hope this helps!:)
Answer:
the two organelles found only in plants include chloroplasts and cell wall.
Explanation:
cell wall is the outermost boundary in most plant cells while animal cells lack it .but the cell wall of plant cells is different from that of prokaryotic cell wall, both in structure and chemical composition.CELL WALL prevents the osmotic lysis of plants and provides them a definite shape. another organelle found only in plants is the CHLOROPLAST. choloroplasts are the type of plastids which are not found in animal cells .choloroplast contain a green pigment called chlorophyll which halp in PHOTOSYNTHESIS. in adition to these plants also contain GLYOXYSOMES and a large "centeral" vacuole which is present in animal cells but it is of small size and pushed towards periphery due to nucleus.
