The correct answer is option A. They either match up with a receptor molecule on the surface of the cell or enter the cell through the membrane.
The intercellular signals are the signals, which transfer the signals from one cell to the another and the intracellular signals are those signals, which carries message within the cell.
The intercellular signals may or may not be transferred through the gap junctions. The chemical signals are one of the type of the cell signals. The chemical signalling molecules generally have a receptor on the cells, where these molecules can bind and can be cause the activation of the cell. The chemical signals can also enter into the cells through active transport and facilitated diffusion. So, these type of transports does not go through the Gap junction.
She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.
In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.
Energy flows through an ecosystem and cannot be recycled.
Room temperature..type of plant..too much sunlight..too much water..or food..thats all i got.
When the muscle or the skeletal muscle cells undergo anaerobic respiration, they become painful and fatingued, it is now known to be caused by build up of lactate. The skeletal muscle will be painful and fatigued and the caused of it will be because by build up of lactate.
