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:
The estrogenic activity of BPA represents the major endocrine-disrupting effect of BPA and was revealed in 1993 by a study showing that BPA can be released from polycarbonate flasks during autoclaving. BPA is a weak agonist to estrogen receptor β, but compared to estradiol, its activity is 1000-fold less
Explanation:
The Human Immunodeficiency Virus (HIV) has been discovered to be the cause of AIDS.
AIDS or Acquired Immunodeficiency Syndrome is caused by the Human Immunodeficiency Virus (HIV). HIV is a retrovirus which contains RNA as the genetic material.
HIV infection can be transmitted through:-
- sexual contact with an infected individual,
- transfusion of contaminated blood samples,
- sharing infected needles e.g. in the case of drug addicts who take the drug intravenously,
- infected pregnant woman to the fetus through placenta.
AIDS adversely affects the immune system of an infected individual. ELISA or enzyme linked immunosorbent assay test is used largely for diagnosing AIDS.
