Yes that's right, its True, are structures that have specific functions
Answer:
Following are the factors are given below:-
Explanation:
In general, the toxicity of a substance depends on the following factors.
- Chemical type and inherent behavior.
- Dosage, in particular the link dose-time.
- Exposure route.
- Species.
- Stage in life, such as child, young adult, or an older adult.
- Gender.
- Fitness to drink.
- Metabolism.
- Allocation inside the organ.
- Excretion
- Human safety, including organ function and childbirth, requiring physical effects that can affect toxicity.
- Nutritional status
- Many chemicals are available.
- Circadian rhythms (the time of day caused by a medication or other substance)
The greater the attractive forces between substrate and enzyme, that
enzyme is said to have a higher affinity for the substrate.
<h3>What is an Enzyme?</h3>
This is a substance which acts as a catalyst in regulating the biochemical
processes of the body.
Enzymes are substrate-specific which means they act only on some types
of compounds. For example the enzyme protease acts only on protein.
When the attractive forces between substrate and enzyme is great then
the enzyme is said to have a higher affinity for the substrate.

Answer:
a. The letters Na with one dot
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such determines or defines the structure of a chemical element.
Generally, atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
In Chemistry, electrons can be defined as subatomic particles that are negatively charged and as such has a magnitude of -1.
Valency can be defined as a measure of the combining power of a chemical element with other atoms to form a molecule or chemical compound.
Valence electrons can be defined as the number of electrons present in the outermost shell of an atom. Thus, valence electrons are used to determine whether an atom or group of elements found in a periodic table can bond with others.
Sodium is a chemical element that is found in group (1) of the periodic table and as such it has 1 electrons in its outermost shell. Also, the chemical symbol for Sodium is Na and it has one (1) valence electron.
A Lewis structure can be defined as a structural representation of an atom or molecule by using a dot to show the position and distribution of electron(s) around the atom or molecule.
Hence, the letters Na with one (1) dot is a correct Lewis structure diagram for Sodium (Na) because it has just one (1) valence electron in outermost shell.
For example, the Lewis structure diagram for Sodium (Na) is •Na.
The correct answer is salivary glands.
Salivary glands are exocrine glands which means that they release their product onto epithelial structure by the duct. There are three major types of salivary glands in h<span>umans: parotid, submandibular, and sublingual as well as hundreds of minor salivary glands. Beside the function of digestion (secrete the enzyme amylase, which hydrolyses starch into maltose and dextrin<span>) those glands have a protective role </span></span>
