<span>Unfortunately, we are not given with the choices in which we could have chosen our answers from. However, in order to determine the mass of an object, we use the balance or the weighing scale. Also, for the volume of the water by graduated cylinder. Then, we divide the mass by the volume. </span>
Answer:
An incubator.
Explanation:
Most enzymes work best at about 37 °C and start to denature around 40 °C.
Thus, the student should use a laboratory incubator, which is essentially an oven that can heat a biological sample to a set temperature.
This model shown below reaches a maximum temperature of 62° C, and its heat controller maintains temperatures within ± 0.5 °C°.
The question is stated incorrectly. The correct question is as follows;
The site of intercellular communication between a neuron and another cell is the.
Answer:
Synapse.
Explanation:
Neurons have dendrites, cell body and axons. Millions of neurons are present in the nervous system. Different types of neuron are sensory neuron, motor neuron and interneuron.
Synapse may be defined as the gap between the two consecutive neurons. The junction between the two neurons that helps in the intercellular communication. The neurotransmitters are diffused directly and transmit information through these synapse.
Thus, the correct answer is synapse.
