In photosynthesis experiment, the effect of the light will be observe during the starch production- thus you need to have a plant without a starch to observe if the starch is produced during photosynthesis. Letting the leaves of the plant deprived from light for 48 hours will be forced to use its reserved starch making the storage of the starch decrease.
        
             
        
        
        
Answer:
An example of passive transport is diffusion, the movement of molecules from an area of high concentration to an area of low concentration. Carrier proteins and channel proteins are involved in facilitated diffusion.

Answer:
AA
Explanation:
A true breeding organism for a particular trait is an organism that would produce progeny  with the same trait whe self fertilized.
Hence, since axial flower is represented by the allele A, a true breeding flowering plant will have the genotype AA.
Axial flower (A) is dominant over terminal flower (a).
True-breeding axial flowering plant will have the genotype AA.
True breeding terminal flowering plant will have the genotype aa.
AA is crossed with aa.
AA   x   aa
offspring: Aa, Aa, Aa and Aa.
All the offspring will exhibit axial flowering.
 
        
             
        
        
        
Answer:
All systems work together to stabilize the body.
Explanation:
Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.
