Answer: The answer is C. An iron atom located on the heme portion hemoglobin
Explanation: Hemoglobin is responsible for the transportation of oxygen in the red blood cells to tissues of vertebrates. It is the protein molecule found in the red blood cells.
Hemoglobin is made up of 4 heme molecules surrounding the globin group, forming a tetrahedral structure. The heme molecules contain one atom of iron each and this is the binding spot for each molecule of oxygen through a covalent bond. Therefore, each hemoglobin molecule can have up to four molecules of oxygen attached to them.
Answer:
Carbon element. Reason for calling us carbon based organism
Answer:
option 1, 2, 4, and 5 are true while 3 is false.
Explanation:
statements are given below.
1) Anaerobic respiration occurs by either lactic acid or alcohol fermentation.
2) Glycolysis is the first step in anaerobic respiration only.
3) only anaerobic respiration produces a net gain of ATP.
4) anaerobic respiration occurs in the cells cytoplasm.
5) aerobic respiration always include the citric acid cycle.
Anaerobic respiration occurs by either lactic acid or alcohol fermentation and produces very low amount of ATP due to the absence of oxygen. Glycolysis refers to the breakdown of glucose molecule in pyruvate and ATP molecules. It only occurs in anaerobic respiration because it does not requires oxygen. Both aerobic and anaerobic respiration produces energy in the form of ATP. Aerobic respiration occurs in the mitochondria of the cell while anaerobic respiration occurs in the cytoplasm. Citric acid cycle is main part of aerobic respiration.
The point on the graph that represents the outbreak of moose ticks and a drastic decline in the moose population is
Point C
The abiotic factors that might cause a rapid change in population size for moose or wolves includes; flood; earthquake, rising temperatures/climate change, ice bridge formation, etc, while the biotic factors include; loss of food source (vegetation for moose, moose for wolves), parasites, shortages of mates, genetic deformities due to inbreeding.
