Answer: uncharged particle found in atomic nuclei
Explanation: A neutron is one of the three components of an atomic nucleus. A neutron has no charge that is, it is unchanged. An atom has three components: electrons, protons and neutrons. The neutrons and protons are located inside the nucleus of an atom while electrons are found outside the nucleus where they revolve round the nucleus. The number of neutrons and protons in a nucleus of an atom makes up the mass number of an element.
Answer;
An ineffective developing solvent was used.
Explanation;
-Quick elution and poor separation are indicative of the compounds traveling quickly up the plate and not interacting sufficiently with the stationary phase.
-Chromatography works on the principle that different compounds will have different solubility and adsorption to the two phases between which they are to be partitioned. Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases are a solid (stationary phase) and a liquid (moving phase).
3. Fimbriae
Fimbriae enable bacterial cells to stick to a surface
Migratory behaviors, such as the particular routes animals use, are said to be instictive. This type of behaviour is also called innate which means that animals perform particular action pattern that is essential for their being. Here are some examples to make it absolutely clear : when animal is shaking water from wet fur, when the spider makes a net, when a bear hibernate. All this behaviours are <span>not learned they just come naturally so that animal will accustom to its environment.</span>
