Some hormones enter cells via receptor mediated endocytosis. Mitochondria contain some of the DNA and RNA code necessary for their own function.
Some hormones enter cells via receptor-mediated endocytosis.
Some hormones enter cells by the process of endocytosis. Endocytosis is where cells absorb molecules. All cells in the body use this process.
Most hormones reach target cells by blood . Some types of hormones reach target cells by other ways e.g. pheromones via air ; local hormones via diffusion etc .
Yes. Hormones are transported throughout the body, via the bloodstream. They do not, however, effect every cell. Only certain cells in the body have the proper receptor sites to accomodate hormones. Therefore, even though hormones are transported right through the body, they only create a reaction for certain things.
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" cells.

Yes. Hormones may stimulate the reversible covalent modification of an enzyme via phosphorylation or dephosphorylation and alter the activity of the molecule.
The pituitary gland is endocrine and so all the hormones it produces enter the blood stream. They do this via the circle of willis which is a ring of vessels that's surrounds the gland. As endocrine hormones they travel throughout the body.

Hormones are chemical messengers that are secreted by the endocrine glands into the blood. Hormones are transported via the bloodstream to reach specific cells, called target cells, in other tissues. They produce a specific effect on the activity of cells that are remotely located from their point of origin.
endocytosis
Supply fuel and oxygen to the cells, and to remove waste products. They also aid in heat distribution, and information (via hormones) spread.
Via voluntary nerves, via autonomic nerves, and via hormones.
blood
The endocrine system is a system of glands that secrete hormones (made of proteins) into the blood stream. Once in the blood, these hormones bind to other protein called receptors in the membranes of the target cells. This is how signals are transmitted
