Answer: Option A) Exocytosis
Explanation:
Unlike the other pathways mentioned, exocytosis involves the outward movement of outside the cells. This is vital in the removal of waste products generated within the cell.
Thus, exocytosis is the answer because it expels materials out of the cell, rather than deliver materials to lysosomes
The way that does not successfully classify protists is their size. Thus, the correct option is C.
<h3>What are Protists?</h3>
Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi.
On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based.
On the basis of how protists get energy and food, they are again subdivided into three categories.
- Animal-like protists: Heterotrophs that have the ability to move.
- Plant-like protists: Autotrophs that have the ability of photosynthesis.
- Fungi-like protists: Heterotrophs have cells with cell walls.
On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia.
Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.

Answer:
2) End Triassic
Explanation:
End Triassic extinction occurred 201 million years ago. It was caused by the rifting of super continent Pangea. Pangea started to break and drift apart. When North america started to separate from Africa, volcanic activity increased. Lava and a large amount of gas was released into the atmosphere specially carbon dioxide. This led to global warming like condition which ultimately caused extinction of a large number of species.
Answer:
The correct option is A. Polycythemia Vera
Explanation:
Polycythemia vera is a myeloproliferative disorder of bone marrow hematopoietic cells that causes excessive production of all types of blood cells.
Primary erythrocytosis occurs as a result of polycythemia vera, in this myeloproliferative disorder the bone marrow produces too many red blood cells along with excessive amounts of white blood cells and platelets. Bone marrow under normal conditions produces blood cells and contains the precursor cells of the three series: red blood cells, white blood cells or leukocytes and platelets or thrombocytes, this disorder is characterized by excessive or uncontrolled proliferation or growth of these cells. The increased production of red blood cells or erythrocytes is called erythrocytosis.
Answer:
Since there is presence of excess tryptophan, the trp operon will be switched off, since the bacterial need not to synthesize.
Explanation:
Understand the following.
The trp operon is a group of gene that encode biosynthetic enzymes for the amino acid tryptophan.
The transcription gene in the operon is switched off when the tryptophan is in excess but is switched on by the bacterium when the tryptophan is low, so that more tryptophan can be produced.
