C)
circulatory; excretory
Eliminate
D)
circulatory; respiratory
Answer: The correct answer for the fill in the blank is A) Circulatory, immune.
Circulatory system also called cardiovascular system is a vast network of organs and vessels that allow the circulation of blood so as to transport nutrients, oxygen, other gases, and hormones to different parts of the body.
Blood contains different cells like white blood cells, red blood cells, platelets.
White blood cells ( also called leukocytes) work closely with immune system. They provide defense against pathogen ( disease causing organisms) through various ways ( like ingesting foreign material, producing antibodies to clear the antigens). By doing so, they protect us from infection and disease.
b. cellular respiration
c. diffusion
d. gas exchange
Answer:
The correct answer would be b. cellular respiration.
Cellular respiration is defined as the set of metabolic reactions taking place in a cell in order to harness energy from food and convert it in the form of ATP (adenosine triphosphate).
It includes glycolysis, pyruvate decarboxylation, Krebs cycle, and oxidative phosphorylation (electron transport chain, and chemiosmosis).
It requires oxygen for complete oxidation of food (glucose) in order to produce ATP and release carbon dioxide as a byproduct.
The overall reaction can be written as:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy (ATP)
Answer:
A: Disruption to electricity power grid.
