Answer:
D gets it's energy from nonliving resources
The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
Saliva gland is held physical and chemical digestion
Answer:
by binding to an ion channel
Explanation:
The neurotransmitters are chemical messengers capable of transmitting a signal from a given nerve cell across biological junctions named 'synapses' to target cells such as, for example, other nerve cells (e.g., neurons). In the cell, the neurotransmitters are transported into internal vesicles that are fused with the cell membrane to release them in the synaptic cleft by the process of exocytosis. Subsequently, the neurotransmitters bind to cell receptors localized on the postsynaptic membrane and thus trigger responses in postsynaptic cells. For example, glutamate is a neurotransmitter capable of exciting nerve cells by binding to a transmitter-gated ion channel called N-methyl-D-aspartate (NMDA).
