Answer:
D
Explanation:
A: Interphase = DNA replication, cells spend most of their time in interphase
B: Prophase = Chromatin condenses and becomes visible
C: <u>M</u>etaphase = Chromosomes line up in the <u>m</u>iddle
D: <u>A</u>naphase = Sister chromatids are being pulled <u>a</u>way
E: Telophase = Cleavage furrow forms
The answer is Catecholamine. It is any of a class of aromatic amines that includes a number of neurotransmitters such as epinephrine and dopamine. The adrenergic receptors are a class of G protein-coupled receptors that are targets of the catecholamines, especially norepinephrine (noradrenaline) and epinephrine (adrenaline). These three - catecholamine, peptide hormones and eicosanoids acts as extracellular membrane receptors which means that these receptors are embedded in the membranes of cells. They act in cell signaling by receiving (binding to) extracellular molecules.

Answer:
Diffusion
Explanation:
The process by which substances move from areas of higher concentration to areas of lower concentration is called diffusion.
For example:
Substance moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
When perfume bottle is open particles spread in air due to difference in concentration from bottle to out side environment.
While,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
