What is true of intercellular signals that do not go through direct connections between cells, such as plasmodesmata? a. the signal fails to reach the inside of the cell, and the cell does not respond. b. the signal is transferred to an adjacent cell for signal transmission. c. an ion-linked channel to the nucleus opens up. d. a receptor molecule accepts the signal and transports it inside the cell.

I believe that what happens here is that when those cells carrying those intercellular signals do no pass through the connections, actually the signal is passed through or are transferred to adjacent cells for signal transmission, hence the answer is:

B

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
