12.5 grams of Flourine 23 would be left after 11 seconds
Answer:
By providing an example using one organ for each of the four levels of complexity, we have the following:First level organ: Skin; this is because it takes up a few cells. Second level organ: Windpipes; this is because they have more complex shapes with multiple cells. Third level organ: Stomach; this is because the stomach has to act on demand instead of a flow. Fourth level organ; Heart. The reason it is difficult to make level four organs in a lab is that it has a complicated architecture with several cells, blood vessels and tiny capillaries included. So far, scientists are yet to fully develop solutions for the level four organs and hence, difficult to create in a lab.
Explanation:
Answer:
The amylase had the higher absorbance with a pH of 7.
Explanation:
Enzyme activity values are given by the spectrophotometric method. The constant temperature is maintained in order to evaluate the pH independent effect. The absorbance is then measured at various pHs and the one that corresponds to the greatest absorbance is the pH at which the enzyme has its peak activity. So pH 7 is the optimal pH condition.
Answer:
Photosynthesis is not taking place and carbon dioxide is not being processed.
Explanation:
The process by which plants make glucose (carbohydrates = energy stores) from carbon dioxide and water is called photosynthesis and uses sunlight energy. A by-product of photosynthesis is oxygen.So plants use water and sunlight to grow and they produce oxygen. Animals on the other hand eat plants, use oxygen and breathe out carbon dioxide.
Since the space station is in the shadow of the earth, the plants are unable to complete the process of photosynthesis and the carbon dioxide that is being produced by the humans cannot be utilized by the plants due to no sunlight. There for the carbon dioxide is going to continue to build up as the energy storage molecules are being depleted and not replenished.
