A water wave should be the answer.. if not then electromagnetic is the closest thing to being correct..
Answer:
Control: sat in silence
Experiment: with music
Independent: The music or no music
Dependant: Their heart rate and pulse
Explanation: Control group: is the one that sat in silence
The one that listened to music is the Experimental Group
The independent variable is the thing that they change, the music
And the dependant variable is what is being measured, their pulse and heart rate
Answer:
The question refers to the classification of enzymes, which can be found in plants or in plants and animals, despite the evolutionary differences some examples in nature can be found that are mentioned below
Only enzymes are found in plants:
1. Malate synthase
2. Isocitrate lyase
In plants and animals we can see that there are:
1. succinate dehydrogenase
2. citrate synthase
3. fumarase
4. aconitasa
5. malate dehydrogenase
<span>Invertebrate<span>, </span>any animal that lacks a vertebral column, or backbone, in contrast to the cartilaginous or bony vertebrates. More than 90 percent of all living animal species are invertebrates. Worldwide in distribution, they include animals as diverse as sea stars, sea urchins, earthworms, sponges, jellyfish, lobsters, crabs, insects, spiders, snails, clams, and squid. Invertebrates are especially important as agricultural pests, parasites, or agents for the transmission of parasitic infections to humans and other vertebrates. Invertebrates serve as food for humans and are key elements in food chains that support birds, fish, and many other vertebrate species.Apart from the absence of a vertebral column, invertebrates have little in common. Indeed, they are distributed between more than 35 phyla. In contrast, all vertebrates are contained within a single phylum, the Chordata. (Phylum Chordata also includes the sea squirts and some other invertebrate groups.) Invertebrates are generally soft-bodied animals that lack a rigid internal skeleton for the attachment of muscles but often possess a hard outer skeleton (as in most mollusks, crustaceans, and insects) that serves, as well, for body protection.</span>
Electrical charged atom or group of atoms formed by lose or gain of electrons are ions
Explanation
Ions are formed when atom gain or lose electron.
They are two type of ion that is cation and anion.
Cation are positively charged ion and are formed when atom loses one or more electrons. for example Na+ formed when Na atom loses 1 electron.
Anion are negatively charged ion and are formed when atom gain one or more electrons. for example Cl- is formed when Cl atom gain 1 electron.
