Answer:
Option D, chloroplast
Explanation:
The process of photorespiration starts in the chloroplast when oxygen attaches to the RuBP. This produces three compounds namely – a) Three carbon compound (3-PGA) and b) Two carbon compound (phosphoglycolate). 3-PGA act as an intermediate to the Calvin cycle and before entering this cycle two of its carbon are removed. To recover lost carbon, plants taken in carbon through series of reactions involving phosphoglycolate. One fourth of the total carbon transported through this pathway is released as CO2. Since this entire process takes place in chloroplast, it can be said that CO2 is produced in chloroplast
Hence, option D is correct
Answer:
The correct answer is - reflexive actions controlled by the spinal cord.
Explanation:
Digestion and breathing are examples of involuntary action which is controlled by the autonomic nervous system of the CNS. however, the part of the nervous system that controls is the spinal cord and hind brain by the spinal reflex actions.
These are the action they do not require any thought and work without any thought that leaves the brain for other actions and coordinations. specific but the same stimuli causes the response in the same way.
Answer:
Nitrogenous bases
Explanation:
DNA is a nucleic acid molecule that acts as the genetic material of the organisms. The structure of DNA is made of two strands of nucleotides that are linked together and form a helical structure. The helical structure is known as the double-helical model with a ladder-like appearance.
The backbone of the ladder is composed of the sugar and phosphate groups at alternate positions whereas the staircase of the ladder are made of the different type of nitrogenous bases (A, G, T, C) joined by the hydrogen bond.
Thus, Nitrogenous bases is the correct answer.
Answer: b. the height of the plant.
In an experimental set up an independent variable is the one which can be manipulated or change to observe the effects of such changes or manipulation on dependent variable. For example, plant growth is a dependent variable because it is dependent on independent variables such as amount of sunlight available, amount of fertilizers and water provided.
In this experiment, it is to be determined that how the amount of water given to a plant affects its growth. Here, water is an independent variable which can be change in the experiment and the affect of change can be observed on plant growth which is a dependent variable. A height represents the growth of the plant therefore, height of the plant is the dependent variable.
Cells are the basic unit of structure and function of all living things.
All cells come from other cells.
Cells are generated from nonliving materials.
Answer:
its C
Explanation:
all cells come from other cells
Southern blot
agarose gel electrophoresis
polymerase chain reaction
Answer:
A. Polyacrylamide gel electrophoresis (PAGE)
Explanation:
Protein fragments of different size can be separated by gel electrophoresis method. Different proteins are made up of different number of amino acids and so the chain length vary i.e. the size of different proteins may vary. Also different proteins may have different charges due to difference in the type of amino acids present in them.
Generally for separating the protein fragments according to their size polyacrylamide gel is used. Foe this proteins are first given the heat treatment and treated with SDS for unfolding the protein. SDS is a detergent that imparts negative charge to protein. During electrophoresis, under the electric field the separation would be only due to size but not charge as all the proteins are treated with SDS and thus have same negative charge. This method is called SDS-PAGE. Under the electric field, small protein fragments will move fast through the pores compared to large fragments leading to their separation.
If two proteins are of same size then to separate them wither agarose gel electrophoresis is used or isoelectric focusing.
