Answer:
conditioned response
Explanation:
The conditioned response, in classical conditioning, is the learned reaction that is elicited by an organism to a previously neutral stimulus, which is now a conditioned stimulus.
In the experiment of Pavlov, where the dog was taught to salivate by presenting food and the sound of the bell at the same time, the dog learns to salivate at the sound of bell alone even without food. This response of the dog is termed a conditioned response to a conditioned stimulus (sound of bell).
The answer is B
Germination is when a seed starts to grow after a period of dormancy
ANSWER: D) lymph vessels and skeletal muscles
EXPLANATION: The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer's patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs
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.
