Answer:
C. CALVIN CYCLE(LIGHT INDEPENDENT REACTIONS OF PHOTOSYNTHESIS.
Explanation:
Photosynthesis is the process whereby green plants manufacture their food (organic matters in form of glucose) from carbon IV oxide and water molecules in the presence of sunlight.
The glucose formed undergoes two purposes; provision of energy and in the fixing of carbon.
This process involved two steps : The light dependent process and the light independent (Calvin cycle).
The light dependent reaction takes place in the thylakoid membrane and requires supply of light energy.
ATP and NADPH are formed, water molecules are also formed.
The light independent reaction occurs in the stoma and does not require light energy. The process used the ATP and NADPH formed from the light dependent reaction to fix carbon and produce three carbon sugars.
So the Calvin cycle light independent reaction is involved in the fixing of carbon molecules into organic molecules in the absence of sunlight and the ATP and NADPH formed from the light dependent process of photosynthesis.
Answer:
The main trait that was different between sharks 14 and 9 was that shark 14 (Mobulidae) has a front with two points that look like horns, whereas shark 9 (Dasyatidae) has a front with no points that look like horns.
Explanation:
Answer:
The protists refer to the unicellular eukaryotic species, which comprise algae, fungi, and protozoa. Of these some are autotrophs and some are heterotrophs. They exhibit the tendency to survive in aquatic surroundings because of their feeding habits.
In older approaches, protists are categorized on the basis of their morphology. However, by using novel approaches like molecular genetics, they are being categorized on the basis of their genetics.
Answer:
The correct answer is option A. "cell fractionation to study the function of specific organelles".
Explanation:
Cell fractionation is a scientific process used to study the function of specific organelles, which main idea is to fractionate the cells but preserving the individual function of the elements of the cell. Usually, the separation takes place by a centrifugation method. This methodology was developed to identify the location of the organelles within the cells, but nowadays is used to study its functions.
Answer
1. The writing utensil’s placement facilitates the drawing of two or more lines with a single stroke of the pantograph. This means while drawing an image two or more copies of varying sizes may be created at the same time. The pantograph mirror is used to extend or retract an image.
2. The operation of a pantograph relates to dilations and similarity in that both of the processes are done on the graph and it is possible to use similar triangles through measuring the size of the triangles. Pantograph contains links that maybe arranged in other ways because they contain a parallelogram.
3. You can use similar triangles to describe the working of the pantograph because the ratio of similitude is set when determining where to put the pin. When one triangle is moved with the part being specific to the point (tracing style), along the outline of the image, an enlarged/reduced version of the image is created by movement of the other triangle (drawing stylus point).
4. Pantograph has been replaced by modern ways of producing duplicates such as photocopying, mass printing and digital filing. This is because the technique is currently outdated and the fact that it is difficult to use then now due to their complex designs which does not allow users to properly grip an actual writing utensil like the pen.
