<span>Leptin, a hormone predominantly made by adipose cells that helps to regulate energy balance by inhibiting hunger, is the hormone secreted into the bloodstream by fatty tissue to signal the hypothalamus that the body has enough food.</span>
Answer: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels. or in materials that the consumer does not digest, or through movement

Answer:
C. H+ ions do not accumulate inside the thylakoid, so ATP synthase makes too little ATP.
Explanation:
Plant withering refers to the virtual death of plant cells due to lack of food. During the light-dependent reactions of photosynthesis, ATP needed for the synthesis of sugar (food) is created in the thylakoid membrane of the CHLOROPLAST of plant cells.
In the light-dependent reaction, hydrogen ions (H+) builds up/accumulate in the thylakoid lumen to create an electrochemical or proton gradient i.e. a difference in the concentration of H+ ions across the membrane. The hydrogen ions passes through a protein complex called ATP synthase, which forms ATP from ADP (by adding phosphate group), from the energy generated by the electrochemical gradient formed as a result of hydrogen in (H+) build up.
Hence, a plant that possess leaky membrane due to the cold temperature will likely wither because H+ ions are not able to accumulate inside the thylakoid causing a proton gradient, so ATP synthase makes too little ATP.
Answer:
Runoff is nothing more than water "running off" the land surface.
<h3>Explenation:</h3>
Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
Answer:
gogi apparatus and the rough endoplasmic reticulum
Explanation:
After the synthesis of proteins in their various site of production, thses proteins needs to be packaged into vessicle for transport to their destination. Vesicles that bud off from the Endoplasmic reticulum will then fuse with the nearest Golgi apparatus membranes, the cis-Golgi. these vessicles continue to travel using vesicle transport through the Golgi apparatus until they reach the end of the golgi appartus budding off — called the trans-Golgi. they are then transported to wherever they are either - the lysosomes, the plasma membrane etc.
