Because those vital organs are extremely fragile the bones act as a type of barrier between the organs and whatever the body may come in contact with. Bones like the ribs protect your heart. Other organ like the eyes, brain, lungs, and spinal cord are all protected by bones or your skeleton.
The answer is D. Mutualism is the symbiotic relationship when both organisms benefit. Predation is not a symbiotic relationship. Parasitism is the symbiotic relationship where one organism benefits and the other is harmed.
Answer:
c. fermentation of pyruvate into lactate to regenerate NAD+
e. the breakdown of glucose
Explanation:
Fermentation of pyruvate into lactate to form NAD+ to drive glycolysis occurs in absence of oxygen in the cytoplasm. It does not include Kreb's cycle and oxidative phosphorylation of aerobic cellular respiration.
Aerobic respiration starts with glycolysis to split glucose into pyruvate and is followed by Kreb's cycle. Pyruvate enters Kreb's cycle in the form of acetyl CoA and is completely broken down into CO2 and H2O.
Oxidative phosphorylation is responsible for ATP synthesis in mitochondria. The dinucleotides (NADH and FADH2) formed during glycolysis and Kreb's cycle are oxidized by giving their electrons to the terminal electron acceptor oxygen molecule via electron transport chain.
The process reduces oxygen molecules into water and also generates the electrochemical gradients across the inner mitochondrial membrane to drive the ATP synthesis.
Answer: A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur
Explanation:
Based on the information given, the possible conclusion that can be drawn from the options given are:
A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
Therefore, the correct options are A, C and E.
