Answer: a. control starfish populations
The Harlequin shrimp is a native of salt water marine environment. It is found near the coral reefs in the Pacific and Indian Oceans. It drives nutrition by eating starfish. They are very skilled in obtaining the starfish as a prey. They firstly eat the tube feet and soft tissues and then the central disk is feeded upon.
Answer:
Energy, carbon dioxide and water vapor
Explanation:
The final product of aerobic respiration are energy, carbon dioxide and water vapor.
- During aerobic respiration energy rich compounds are broken down into simpler units to liberate energy.
- This metabolic reaction is said to be a catabolic step or procedure.
- It is the reverse of what happens during photosynthesis.
- Therefore as glucose combines with oxygen gas, the product derived is energy, carbon dioxide and water vapor.
Answer:
Brain
Explanation:
A shock is a medical condition which is caused when the body has the less available substrates for the aerobic respiration and shift to anaerobic cellular respiration.The shock takes place in four-stage in which the second stage is the compensatory stage.
During the compensatory stage, the sympathetic nervous system gets activated to shift back the respiration from anaerobic respiration to aerobic respiration.
The sympathetic nervous system releases the epinephrine and nor-epinephrine which acts on the kidney to maintain blood pressure. During this process, the Brain is not affected by the shock condition.
Thus, Brain is correct.
Answer:
The most appropriate answer would be C.electron carriers such as NADP⁺.
High energy electrons are transported through electron transport chain embedded in a thylakoid membrane in order to produce energy rich compounds such as ATP and NADPH.
It is also called as light dependent reaction of photosynthesis. It includes four major protein complexes: photosystem II, photosystem I, cytochrome b6f complex, and ATP synthase.
The electron first gets excited from chlorophyll a present in the reaction center (P₆₈₀ and P₇₀₀) of two photosystems (PS II and PS I) . The electron in PS II is replenished by photolysis of water.
Different electron carriers (such as plastoquinone, plastocyanin, pheophytin, chlorophyll A₀ etc) are present which help in transferring this high energy electron from one complex to another. NADP⁺ is the final acceptor of the electron and gets reduced to NADPH.
NADPH and ATP are then used in dark reaction in order to fix carbon into sugars.
