Answer:
In the fungal life cycle, karyogamy results in D. fungi haploid nuclei from two parent fungi fuse together
Explanation:
Karyogamy has an important role in sexual reproduction. It is the last step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. This is the steps that usually follows the Plasmogamy stage. This step is part of the sexual reproduction of fungi too. Karyogamy is key because it helps recombine two different genetic material.
CD4 and CD 8 are molecules present on the surface of T cells where they interact with major histocompatibility (MHC) Molecules.
CD4 and CD8 improve T cell signalling by attaching to MHC class II (CD4) or MHC class I (CD8) molecules on APCs.
- The association of CD4 with MHC class II significantly decreases the number of antigenic peptides necessary for T cell activation (5) and significantly boosts cytokine output by helper T cells.
The MHC molecules' wide polymorphism is their distinguishing trait.
- This polymorphism is crucial for T cell antigen recognition.
- A T cell detects antigen as a peptide bound by a specific allelic variation of an MHC molecule and will not identify the identical peptide bound by other MHC molecules.
- This type of T cell activity is known as MHC limitation.
Hence, the correct answer is option C

Answer: Protease is within
Lipase is within
Carbohydrase is within
Explanation:
Because a pH of 9.1 is within the green area for every graph, Claire’s pH is within the optimal range for every enzyme.
The answer is mitochondrion, it is called as "the power of cell"
