Answer:
ionic bond: An attraction between two ions used to create an ionic compound. This attraction usually forms between a metal and a non-metal. covalent bond: An interaction between two atoms, which involves the sharing of one or more electrons to help each atom satisfy the octet rule.
Explanation:
The three structures that are most likely found in all fish are: blood, fins, and gills.
Answer:
Speech and language brain regions. The visual cortex is the part of the cerebral cortex that is responsible for processing visual information. The auditory cortex in the cerebral cortex processes auditory information and as part of the sensory system for hearing, performs both basic and higher hearing functions.
Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
