Answer:
Explanation:
In metaphase (a), the microtubules of the spindle (white) have attached and the chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
Answer:
Activation energy may be defined as the minimum amount of the energy required to convert the substrate into the product. The higher the activation energy of a reaction, the slower the speed of a reaction.
The enzymes decreases the activation energy of the reaction and increases the effective collision between the substrate. The enzymes does not change the DG (delta G) or free energy of the reaction. The enzymes maintain the equilibrium of the reaction by increasing the equal amount of the forward and backward rate of the reaction.
Answer:
sister taxa
Explanation:
Groups departing from the same evolutionary node are called sister taxa and are evolutionarily closer to each other than groups departing from another node. Thus, we can say that the sister taxa are evolutionarily closer (related) to each other than to the taxa that did not diverge from the same place. Similarly we can say that taxa that did not diverge from the same place, cannot be called sister taxa and are distant evolutionary.
If the temp.rises then it will lead to excessive evaporation in hydrosphere, on lithosphere it willl cause extreme hot conditions and with the scarcity of water the animals, birds will die and also plants will be affected.Hydrosphere and lithosphere are included in biosphere so it willl altogether effect biosphere...
Answer: The upper gastrointestinal tracts organs consist Esophagus, stomach and duodenum.
Explanation:
Gastrointestinal tracts is a organ system found in human beings and other animals that deals with intake of food, digestion of food, adsorbing nutrients from the digested food and expelling or excreting the waste products and undigested food.
The gastrointestinal tracts is divided into two, the upper and lower gastrointestinal tracts. The upper gastrointestinal tracts organs consist of Esophagus, stomach and duodenum while the lower gastrointestinal tracts consist of the large and small intestine. The structures include anus, colon,rectum,caecum.
