How do hormones send messages?
The cells that react to a given hormone have special receptors for that hormone. When a hormone attaches to the receptor protein a mechanism for signaling is activated.
What determines if a cell is a target cell for a particular hormone?
If the signal molecule is able to fit through the cell membrane, it will bind to an intracellular receptor, if it cannot pass through the cell membrane, it will bind to an external membrane-surface receptor.
What is process in which glucose and oxygen react in cells to release energy is called?
Its either Photosynthesis or cellular respiration
How do plant cells capture and store energy?
The cells have tiny organelles called Chloroplasts that react to sunlight and create energy that combines with glucose and then becomes stored in the Large Central Vacuole to be used at a later time by the mitochondria which breaks down the compounds and releases the energy.
In what important function are the cells of you eyes involved?
Retina of human eye has 2 types of cells called cone cells and rod cells. Cone cells are photoreceptor cells in the retina. The function of these cells is in bright light. Rod cells function in less bright light. There are 4.5 million cone cells and 90 million rod cells in human retina. There are three types of cone cells. First type of cone cells called L which respond to light of long wavelength with peak sensitivity in the yellow region. Second type of cone cells are called M which respond to light of medium wavelength with peak sensitivity in the green region. Third type of cone cells called S which respond to light of short wavelength with peak sensitivity in the violet region.So, cone cells are not related with eye vision but are related with the perception of color. That is why if a person born without corn cell will be able to see but he will have another problem called color blindness.You can find the detailed diagram on this site examville.com for better understanding of the topic.

What does the thymus secrete to stimulate T lymphocytes?
Im afraid that your question is quite unclear. If you are refering to how the thymus turns pre-T Cells into Naieve T-cells, this is not a process mediated by a secretion. Its a process called positive and negative selection (or central tollerance) mediated by surface molecules called MHCs present on thymic cells and Dendritic Cells, which eliminates those cells that either do not react with these MHCs or react too strongly. I hope this answers your question.............
If hormones travel in the bloodstream why don't all tissues respond to all hormones?
The tissue/cells need a receptor that can interact with that hormone in order to respond to it. This receptor may be on a cell membrane, inside the cell, or even inside the nucleus (in the case of steroid hormones, for example.) Like many organic chemicals in the body, they have structures which result in certain parts of the molecule being presented to cells (active sites). Because cells and tissue have different structures as well, only certain cells will react to the presence of a particular hormone. Many hormones have antagonist hormones that cause an opposite effect. This helps control negative feedback when the target organ's hormone levels are too high.
A hormone which enables the body to react quickly?
Epinephrine (called adrenaline in non-US English speaking countries)
What is the idea that offenders react selectively to the characteristics of particular crimes called?
offense-specific
What is a word for a chemical in the body that causes you to react very quickly?
There is a hormone called epinephrine, also known as adrenalin. This may be what you are wondering about.
The clumping of cells that occurs as a result of an antigen-antibody reaction is called?
When an antigen and antibody react it causes cells to clump together. The term used to describe the clumping of cells is called agglutination.
What is the hormone that enables the body to react quickly?
the thyroid gland
Which hormone helps us to react to fight or flight?
adrenaline.
What hormone helps you react quickly in dangerous situation?
adrenaline
What mixtures that can react with acids or bases to keep the pH within a particular range?
These substances are called buffers.
What is Catalysing metabolic reactions in cells?
They create a site for reactants to react. This is called the enzyme-substrate complex.
