By the ligand receptors on the surface of the cell membrane. How do transport proteins make it easier for certain molecules to diffuse across a membrane.
the binding of a signaling molecule, or ligand, to its receiving molecule, or receptor.
Accumulating physical activity experiences is the key to improve our physical activity performances.
Answer:c. Dendrite → cell body → axon hillock → axon
Explanation:a neuron has many cytoplasmic extensions called dendrites.the dentrites enter into the cell body at one end . the cell body also leads to axon at the other end, which extends toward another dentrite.axon hillock connect the axon to the cell body.
Impulses are usually transmitted along the neuron in one direction.
From the dendrites to the cell body,to the axon hillock and then to the axon.
The answer is <span>A. codon ® gene ® DNA ® chromosome.
</span>Codons are base triplets (three nucleotide bases) on DNA.
Genes are sequences of DNA that typically contain the code for
a particular protein.
<span>DNA is a two-stranded helix consisting of nucleotides.
</span>Chromosomes consist of DNA molecule that is packaged into thread-like structure.
