Solution :
In Gizmo experiment, when both the intensity of light and carbon dioxide level is high, the rate of photosynthesis will maximize.
A). If the temperature is too hot or cold, it becomes difficult to find the ideal intensity of light because if the temperature is hot, the light intensity will be too high and thus the chlorophyll will get damaged. While if it too low, then it will be difficult for the proper functioning of the cells. And hence the photosynthesis will not take place.
B). It will be considered as a limiting factor if the light intensity is low. With light intensity being low, it will be difficult for the plant for survival and ideal carbon dioxide level will have no role. This amount of carbon dioxide does not help the plant to survive as the light intensity is now a rate limiting factor.
Explanation:
During PCR, we use two primers one is forward primer and the other one is reverse primer they match the sequence of one one of the two complementary strands of the target DNA, they flank the target region (that the region which we has to be copied). if we add only one primer it copies only one strand of the DNA in multiple copies. Usually we call this as Asymmetric PCR.
Generally Primers are synthetic short stretch of oligonucleotides that are complementary to the target DNA. They act as a foundation for the amplification process of DNA to form multiple copies

Explanation:
The events of muscle contraction begins from the presynaptic neuron, which cause the influx of Ca+, and the release of acetycholine neurotransmitter into the synaptic cleft.
The Ach, binds with the receptors in the sarcolemma, leading to opening of Ligand gated Na+ channels. Therefore Na+diffuses in, causing depolarization, and propagation of action potential along the sarcolemma spreading to the T-tubules.
This is followed by opening of Calcium channels leading exist of Ca+ from the sarcoplasmic reticulum.
The Calcium binds with the troponin, and Tropomysoin exposed the myosin binding sites on the actin filament.Thus cross-bridge is formed by the myosin head with thin filaments which shortened the sarcomere, leading to contraction of muscle fibres.
The crabs are salt water organisms, so they'll have a higher concentration gradient than the distilled water. In other words, they're hypertonic to the distilled water. This will cause them to take on water and expand; their cells bursting.
