Answer:
Answer:
Gene expression is the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. ... Each group of three bases (codon) corresponds to one of 20 different amino acids used to build the protein.
OR
Gene expression is. the activation of a gene leading to the transcription, translation and synthesis of a specific protein.

Explanation:
Sounds like you are describing the brain.
Answer:
-70 mV
Explanation:
Given that Neuron A and Neuron B interact with Neuron C
Neuron A produces ; - 2mV of IPSP and fires 6 times
Neuron B produces ; 3mV of EPSP and fires 4 times
Resting potential = - 70mV
threshold = - 50mV
The resulting membrane potential in neuron C
= -70 + 6(-2) + 4(3)
= -70 - 12 + 12 = -70 mV
Answer:
cells suddenly become flaccid after stimulation because of the loss of K+
Explanation:
Nastic responses are non-directional movements of parts of plants in response to diffuse stimuli. The closinf of leaves of<em> </em><u><em>Mimosa</em></u><em> </em><em><u>pudica</u></em> when touched is a type of haptonastic response. These movements are brought about by turgor pressure changes of the leaf and the petal bases. At the bases, there are pressure sensitive swellings called pulvini which through loss of turgidity cause nastic movements.
According to research, cells go through an efflux of potassium (K) which leads to the reduction of turgor. Direct quote on Reed-Guy et al. (2017)'s paper "This mechanism is initiated when a stimulus causes an efflux of potassium within the leaf, creating a loss of turgor pressure, which closes the leaves and causes them to droop."
