what is true of intercellular signals that do not go through direct connections between cells such as gap junctions? (A.They eit
her match up with a receptor molecule on the surface of the cell or enter the cell through the membrane) (B. The carbohydrate tag is interpreted in the ribosomes, and the signal is passed on to the nucleus of the cell) (C. They connect with another cell part such as the Golgi apparatus, where hormones interpret the signal) (D. They connect with an adjacent cell where an ion linked receptor carries them into the nucleus)
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.
During the summer months, the water table tends to fall, due in part to plants taking up water from the soil surface before it can reach the water table. The water table level is also influenced by human extraction of groundwater using wells; groundwater is pumped out for drinking water and to irrigate farmland.
Science is based on the feature of "<span>detailed research with reliable sources" among many other things. It is crucial that the tests can be repeated with the same results. </span>
