Answer:

a. Australopithecine Afarensis

Explanation:

With a skull of 3 million years, scientists have been able to prove the existence of Australopithecus afarensis, the oldest ancestor of humanity. 4 million years ago, humanity did not exist. But at least one creature bore in its bones what would be the hallmark of Homo sapiens. Australopithecus afarensis, that creature's name, had a tiny brain. But it stood like no monkey could do, representing an ancestral trait that would be passed from generation to generation to modern man.

Antibodies are complementary to these antigen binding sites, and the antibodies have an incredible ability to recognize a great variety of antigens.

Answer: Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. The lifespan of neutrophils is 5-90 hours, whereas eosinophils lifespan is 8-12 hours and that of basophils have a life span of 60-70 hours. functions- All the granulocytes present in white blood cells play their role in fighting against pathogens and in destroying them, where neutrophils vital role is in engulfing the foreign or toxic particles through phagocytosis; Eosinophils are the first one in triggering the inflammatory response during allergic disorders; and Basophils prevents the immediate blood clotting, as it contains heparin (anticoagulant) in the body. structures- Neutrophils have a two-lobed or bilobed nucleus, while eosinophils have bean-shaped nucleus and basophils have a multi-lobed nucleus. ... Neutrophils make up to 40-75% of the total white blood cells, while eosinophils mark their presence up to 1-6% and basophils are up to 0.5-1% of the whole white blood cells.  stained- Neutrophils:Neutrophils are stained in natural pink color. Eosinophils: Eosinophils are stained in brick red in acidic stains. Basophils: Basophils are stained in dark blue in basic stains. counts- Neutrophils are one of the primary types of white blood cells, that evokes the immune response against any foreign particle attack in the body. Eosinophils are another type of white blood cells, that helps in fighting against disease and allergies.
