WITH 100% VERIFIED ANSWERS
\.What is homeostasis? - ANSWERS-How your body tries to keep your internal
systems balanced and working.
\.What mechanism does your body use to counteract changes in homeostasis? -
ANSWERS-Negative feedback
\.What are examples of negative feedback in the body? - ANSWERS-Blood
pressure, Oxygen levels, Body temperature
\.What mechanism does your body use to strengthen a response until it isn't
needed anymore? - ANSWERS-Positive feedback
\.What are examples of positive feedback in the body? - ANSWERS-Blood clotting,
Immune responses, Inflammation
\.What does every disease that affects your body involve? - ANSWERS-A disruption
of homeostasis
,\.What is involved in the physiological adaptation of Learning and Memory? -
ANSWERS-Synaptic plasticity, CREB activation, and epigenetic remodeling of
neurons.
\.How does Muscle Anabolism occur in response to exercise? - ANSWERS-Exercise
induces hypertrophy via Myc, mTOR signaling, and epigenetic regulation.
\.What happens during Adaptive Immunity? - ANSWERS-B and T cells undergo
clonal expansion, DNA recombination, and epigenetic changes for memory.
\.What is involved in Metabolic Adaptation? - ANSWERS-Mitochondrial biogenesis
and shifts between glycolysis and oxidative phosphorylation, depending on energy
needs.
\.What are the key features of Cancer as a maladaptation? - ANSWERS-
Dysregulated transcription factors (Myc, Fos), epigenetic silencing of tumor
suppressors, and metabolic rewiring (Warburg effect).
\.What occurs in Cardiovascular Remodeling due to chronic stress? - ANSWERS-
Hypertrophy, fibrosis, and maladaptive gene expression.
\.What characterizes Autoimmunity as a maladaptation? - ANSWERS-Epigenetic
and transcriptional dysregulation of immune tolerance leading to inappropriate
immune activation.
, \.What is a feature of Type 2 Diabetes in terms of maladaptation? - ANSWERS-
Impaired metabolic plasticity, mitochondrial dysfunction, and maladaptive insulin
signaling.
\.What role does Adaptive Transcription play in physiological adaptation? -
ANSWERS-Drives gene expression in response to stimuli like exercise, learning,
and immune activation.
\.What can overactivation of Adaptive Transcription lead to? - ANSWERS-
Oncogenesis or pathological remodeling.
\.What is the function of Epigenetic Remodeling in adaptation? - ANSWERS-
Stabilizes adaptive changes like memory and immunity.
\.What can aberrant epigenetic remodeling lead to? - ANSWERS-Cancer,
autoimmunity, and metabolic disease.
\.What does Metabolic Plasticity adjust? - ANSWERS-Energy metabolism to meet
demands.
\.What maladaptations can result from Metabolic Plasticity issues? - ANSWERS-
Insulin resistance, cardiovascular disease, and cancer metabolism.
\.What leads to cellular stress response mediators? - ANSWERS-Stressors
