Answer:
Homology is a study of similar characters found in two species because of common ancestry.
Explanation:
1.Morphological homology: Species placed under same taxonomic category exhibit similar anatomical structures.
2.Ontogenetic homology: Species belongs to same taxonomic category embryological similarities
3.Molecular homology: Species show molecular similarities such as DNA,RNA and protein
An example of homology is seen in the skeletal strycture of vertebrates. That is arm of a human,leg of a cat,fin of a whale and wing of a bat.
Neutrophils They kill and then digest the bacteria and the fungi. They are the most numerous type of the white blood cell and your first line of the defense when the infection strikes.
A high level of neutrophils in the blood is called neutrophilia. This is a sign that your body is infected. Neutrophilia can indicate many underlying conditions and factors, including: Infection, possibly bacteria. They capture and destroy invading microbes through phagocytosis and intracellular degradation, release of granules, and formation of neutrophil extracellular traps upon detection of pathogens. Neutrophils are also involved as inflammatory mediators. What is the most common cause of high neutrophils? infection. This is the most common cause of high neutrophil counts. Most bacterial infections cause elevated neutrophil counts, but not all. Viral infections generally do not cause neutrophilia, but it can occur early in the infection.

Metales alcalinos
El grupo 1A (o IA) de la tabla periódica son los metales alcalinos: hidrógeno (H), litio (Li), sodio (Na), potasio (K), rubidio (Rb), cesio (Cs) y francio (Fr). . Estos son (excepto el hidrógeno) metales suaves, brillantes, de bajo punto de fusión y altamente reactivos, que se empañan cuando se exponen al aire.
