Families contain elements with similar characteristics, usually determined by the number of electrons in the outer electron energy level. atomic number atomic mass symbol element name Alkali Metals The alkali metals have 1 valence electron. They're soft metallic solids, with characteristic metal properties of shiny luster and high thermal and electrical conductivities. The alkali metals have low densities and melting points, increasing and decreasing respectively with increasing atomic mass.
The alkali metal react vigorously with water, producing hydrogen gas and a solution of an alkali metal hydroxide. These reactions are very exothermic, in many cases generating enough heat to ignite the H , producing fire or sometimes even an explosion.
The answer that best completes the statement above is this: <span>toddlers maintain a capacity to discriminate language sounds they have never heard. This is considered to be one of the best evidences for language acquisition. This is based on CPH or the Critical Period Hypothesis. This states that in the first years of life, humans use this time in order to develop language and readily use this but at the age of 5 and beyond, language acquisition becomes more challenging and difficult.</span>
The LDL receptor and transferrin receptors are examples of receptors that function by receptor-mediated endocytosis. The LDL receptor is a transmembrane protein of the plasma membrane. Occupancy of the ligand binding site of the LDL receptor in the extracellular domain of the receptor by LDL initiates endocytosis.
<h2>C) is the correct option </h2>
Explanation:
To best convey the exact name of an organism to others in same field one should as a group, decide on an alternative that everyone understands
Names are important because they allow people throughout the world to communicate unambiguously about animal species because there are sets of international rules about how to name animals and zoologists try to avoid naming the same thing more than once, though this does sometimes happen
These naming rules mean that every scientific name is unique
The genus is the first level of taxonomic organization, in a way, because all species that are thought to be most closely related, are placed together in a genus
Scientific names are often descriptive also, suggesting something about the animal
Common names are not unique because of which it can lead to confusion about what animal is being referred to and what their relationships are to other animals
Law of conservation state that energy cannot be created or destroyed
