Answer:
1: Light-dependent reactions:
Reactants: H2O, ADP, NADP
Products: O2, ATP, NADPH
Location: Thylakoid membranes of chloroplasts in cells of leaves
2: Light-independent reactions
Reactants: CO2, H2O, ATP, NADPH
Products: C6H12O6 (glucose), ADP, NADP
Location: Stroma of chloroplasts in leaf cells
Explanation:
Photosynthesis takes place in two stages:
1: Light-dependent reactions: This stage includes splitting of water in the presence of sunlight and release of electrons and oxygen gas. The electrons are channeled into the electron transport chain and result in the formation of ATP and NADPH. This stage includes photosystem I and II present in the thylakoid membrane. Hence, light-dependent reactions of photosynthesis occur in the thylakoid membrane of chloroplasts and form ATP and NADPH.
2: Light-independent reactions: Also called as Calvin cycle, the light-independent reactions use ATP and NADPH formed during light reactions of photosynthesis to fix CO2 into glucose. The enzymes of the Calvin cycle are present in the stroma of chloroplasts and hence, this stage of photosynthesis occurs in the chloroplast stroma.
Answer:
B
Explanation:
The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.
In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.
If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)
However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.
According to the phylogenetic tree, Eukarya evolve <u>First in the Prokaryotic Organisms.</u>
Answer:
The correct answer is true.
Explanation:
Swallowing of food is the process of passing the food from the mouth to the stomach through the way of the throat (pharynx) and esophagus. This process takes place in three stages: oral, pharyngeal, and esophageal stages
During the pharyngeal stage, epiglottis which is a leaf-shaped flap of cartilage located at top of the larynx (a muscular organ forming voice box) perform functions in response to the swallowed food as the larynx lift up or rises inside the neck to close the epiglottis while the epiglottis moves downward to cover it, providing more airway protection.
Thus, true is the correct answer.
Producers create food by them selves from the sun but consumers eat the producers they both consume food. But the consumers get less energy than the consumers cause they pass on less energy than they consume hope it helps
