the correct answer would be C. Coffee is a homogenous mixture.
Answer:
In a postsynaptic cell/neuron where a depolarizing change in the membrane potential surpasses the threshold.
Explanation:
Generally, in an excitable cell, the neurotransmitter binding opens the ligand-gated channels at the synapse. Here only the entrance of the ions will not stimulate the action potential. They must exceed the threshold. Hence, an action potential will only get incited when in a postsynaptic cell/neuron, a depolarizing change in the membrane potential surpasses the threshold.
A. once defined, an ecosystem is a unit scientists can analyze.
Fibroblasts, cells found in the connective tissues of the body, make up the hypodermis. These produce collagen proteins, which aid in preserving the body's structural foundation.
- The body's bottom layer of skin is called the hypodermis. It serves a variety of crucial roles, including energy storage, tying the muscles and bones beneath the skin's dermis layer to one another, keeping the body warm in a variety of temperatures, and guarding against injury-related harm.
- The hypodermis shrinks with ageing, the skin begins to sag, and the skin is more susceptible to damage and injury.
