Hormones and neurotransmitters
When a specific protein on or in a cell has a shape that fits a particular molecular messenger, such as a hormone, it can bind to that messenger. This binding typically triggers a response within the cell, often activating or inhibiting certain cellular pathways. This mechanism is crucial for cellular communication and regulation, allowing cells to respond appropriately to various signals in their environment. The specificity of this interaction ensures that only the correct signals elicit a response, maintaining cellular homeostasis.
Yes.
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
Chemical indicator dye is a substance that changes color in the presence of a specific chemical or changes in pH. It is commonly used in laboratories to visually indicate the presence or absence of certain substances in a solution.
MnO can act as a catalyst in certain reactions, such as the decomposition of hydrogen peroxide. However, its catalytic activity depends on the specific reaction and conditions.
Regulatory commissions are government bodies that are set up to keep certain things in check. Regulatory commissions prevent excesses and give direction on how a project or task should be undertaken.
There isn't a specific chemical formula for "butter of tin" as it is not a defined chemical compound. However, "butter of tin" can refer to stannous chloride (SnCl2), a compound used in certain chemical processes.
Yes, a Series 7 license can be reinstated after it has expired, but the process may vary depending on the regulatory authority and the specific circumstances of the expiration. Typically, individuals must meet certain requirements, such as completing continuing education and possibly retaking the exam if the license has been expired for an extended period. It's essential to check with the Financial Industry Regulatory Authority (FINRA) or the relevant regulatory body for the specific steps and requirements for reinstatement.

Yes it is a reaction to a specific substance like dust, pollen, drugs, chemical, soaps, cosmetics, certain food items etc.

Neurotransmitters are the chemical messengers that the neurons use. Neurons have certain parts...dendrites which receives information (about some stimulus or from another neuron)...axon is the part of the neuron that conducts/conveys the signal to the synaptic terminals. The synaptic terminals is the part of the neuron that releases the chemical messenger aka the neurotransmitters.
It means a certain chemical transformation of specific changes in elements. They are crucially important in the world of Chemistry and science in general.
Yes.
Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
There are certain types of chemical reactions describing what happens to certain reactants, such as combustion, single replacement, double replacement, etc. All of these processes change one kind of reactants (original substances) into different products (new substances) with a new combination of atoms arranged in a way to have completely different properties.Chemical reactionsare chemical changes. Reactions are just more specific.
They are supposed to protect the public. They make and enforce rule for certain industries or groups.
