Answer:
The correct answer is option d.
Explanation:
An extinct species of australopithecine, that is, Australopithecus africanus was the first species to be illustrated. It was of gracile or slender build and was considered to have been the direct ancestor of modern humans. Like modern man, the A. africanus did stood upright and walked upright, and were having free hands to use. However, they were smaller in height and lighter in weight in comparison to modern man.
Mostly bacillus (bacteria with cylindrical/rod shaped morphology) I'm pretty sure, you don't see any type of coccus (bacteria with spherical morphology) with flagella.
Answer:
antibodies being produced to fight off a pathogen inside the body
Explanation:
Specific immune responses, also known as the adaptive immune system are ways the body fights against pathogens. The body is able to identify cells that are unique to it. When pathogens bearing an unknown identity enter the body, antibodies are released to attack the antigens on the surface of these pathogens.
The body usually develops this immunity after a previous attack by the pathogen. Lymphocytes known as the B and T cells are released by the immune system t engulf the pathogens.
The cell divides and grows in the organ of origin, causing a localized tumor. Cancer cells then spread to adjacent tissues or regional lymph node drainage areas, and then advance to distant organs or structures, creating metastatic tumors.
