Answer:
The correct answer is -Biosocial perspective.
Explanation:
In the last few years, the research and thinking on biosocial perspectives on the family come in light. The biosocial perspective on the family is characterized by concepts or laws related to various psychological factors to evolution, genetics, and physiology.
Three major developments that are contributed in this perspective are findings of proximate biological interplay, advances in evolutionary thinking and alteration in the field of studies related t the family.
Thus, the correct answer is - the biosocial perspective.
Disruptive selection describes changes in population genetics in which extreme values for a trait are favored over intermediate values.
The horse and mouse are endotherms among them rat will have high mass-specific metabolic rate.
The shark and fish are endotherms among them fish will have high mass-specific metabolic rate.
Explanation:
The endotherm (heat requires in them to maintain internal temperature of the body) organism have high metabolic rates to maintain homeostasis, this requires the large amount of energy. Smaller animals have the greater surface area to volume ratio, hence more heat loss and higher metabolism. In larger animals body volume increases, surface area increase is also very slow, hence less heat loss and lower Metabolic rate. Smaller animals exchange oxygen to tissues at a high rate.
Same goes with ectotherms the larger the animal the smaller is the metabolic rate. During winters their activity slows down as they cannot adjust with the temperature of the surrounding.
However metabolic rates of ectotherm and endotherm cannot be compared.
Answer:
B is most likely used for reproduction.
Answer:
The electron transport chain (ETC) is located in the mitochodrial cristae. As electrons move from one protein complex to the other via redox reaction, energy is used to pump hydrogen ions (H+) from the matrix to the intermembrane space of the mitochondria. As hydrogen ions flow down the concentration gradient from the intermembrane space to the mitochodrial matrix, ATP is synthesized by the enzyme ATP synthase.
The ATP synthase complex can be compared to the gates of a dam. when the gates of a hydroelectric dam are opened, water rushes through, and electricity (energy) is produced. Similarly, when H+ ions flow down a gradient from intermembrane space into the matrix, the enzyme ATP synthase synthesizes ATP from ADP and inorganic phosphate or P<em>i. </em>This process is called chemiosmosis because ATP production is linked with the establishment of a proton (H+) gradient across the membranes.
