Answer:
White blood cells are the cells which play an important role in providing immunity to the body. The WBC can be categorized into five types which perform distinct functions in immunological response.
In the given question, since the WBC is engulfing the bacteria particle by the process of phagocytosis. The WBC contains cytoplasm and bilobed nucleus, therefore, this could be wither a neutrophil or eosinophil.
Answer:
nitrogen
Explanation:
Answer:
Explanation:
According to the nutrition between the fox, the rabbit and the lettuce, it can be concluded:
-All three belong to the food chain of a specific region.
-The lack of any, would make the chain unbalanced, breaking it.
-The fox is a carnivore, so it feeds on the rabbit. While the rabbit is herbivorous, it feeds on plants.
-The rabbit and the fox are mammals, while the lettuce belongs to the Asteraceae family.
b. parasitism
c. competition
Answer:
Parasitism
Explanation:
Parasitism may be defined as a biological interaction in which one organism (parasite) lives on the body of other organism (host). The parasite can directly obtained ready-made food from the host.
Lamprey attaches with another fish , can directly obtain nutrient and may cause harm to fish. Here, lamprey is parasite and the fish acts as a host for lamprey.
Thus, the correct answer is option (b).
Answer:
Enzymes
Explanation:
Amoeba uses enzymes to breakdown organic molecules because enzymes are biological catalysts that help to speed up the rate of chemical reaction or breakdown large molecules.
Amoeba have vacuole which fuses to the lysosomes by cytoplasmic movements. The lysosomes are organelles that contain enzymes amylase and proteinase which help to digest carbohydrates and proteins.
An amoeba in a pond uses enzymes to break down the organic molecules in a paramecium that it engulfs and consumes.
An amoeba, a type of single-celled organism, engulfs its food and then breaks it down using a biological catalyst known as enzymes. The enzymes are involved in the process of digestion, which allows the amoeba to obtain nutrients and energy from its food, in this case, a paramecium. Enzymes work by lowering the activation energy for a reaction, making it easier for the reaction to occur and therefore the digestion process in amoeba happens more quickly.
