Answer:
deficiency of color vision in which the person can match any given hue by mixing only two other wavelengths of light (as opposed to the three wavelengths needed by people with normal color vision) synonyms: dichromasy, dichromatism, dichromatopsia, dichromia.
Answer: Pteridophyte
You classify the plant as a pteridophyte
Explanation:
Pteridophytes are known to have the following:
- many cells (multicellular) and vascular bundles
- true roots, stems, and leaves
- do not produce flower throughout their lifespan
- they are mainly terrestrial plants, while few are aquatic
- do not produce seeds but reproduce asexually by formation of spores
Examples are ferns
<span>The answer is </span><span>C. haploid, and are made when haploid spores undergo mitosis. </span><span>
Pollen grains are male gametophytes in plants. In pollen sacs of an anther, spore mother cells, which is diploid, undergo meiosis and form four haploid spores. These haploid spores undergo mitosis and form haploid pollen grains.
Through the process of elimination:
- Pollen grains are haploid, so choices A. and C. are eliminated.
- In ovules, female gametes are produced, not male gametes, so, choice D. is also eliminated.</span>
Answer:
False
Explanation:
G-Protein Coupled Receptors (GPCR):
GPCRs are transmembrane receptors with three components:
- Extracellular domain for ligand binding
- Seven transmembrane helices
- Intracellular G-protein binding domain
Transmission Through GPCRs:
- A ligand binds to the extracellular domain of the GPCR.
- The GPCR undergoes conformational changes.
- This conformational change activates the G-protein by replacing its bound GDP (guanosine diphosphate) with GTP (guanosine triphosphate).
- The G-protein then loses its GTP bound alpha subunit which activates the adenylyl cyclase system.
