Invasion biology terminology

Insect is an animal category that has a hard body on the outside knows as exoskeleton which are animals with three pairs of leg. They are recognized the insect which have evolved from worm-like ancestors. Through research by today’s researcher, he found that, “these insect ancestor were wingless and developed without metamorphis, for an example as silverfish that were present today” (Barnes, 1987). Insects have a lot of interest as their habits are the most diverse among other kingdoms, their…

In the Wells's novel, humanity is in a war against Martian invasion. The setting of the war is in 19th century Britain and the British military is at the verge of losing it. The novel starts with comments on how humans have been mistreating earth, such as " ... we must remember what ruthless and utter destruction…

Question 1 1.1) Hemichordates share some characters with echinoderms and chordates. Pharyngeal slits they share with chordates. Hemichordates are the sister taxon to echinoderms as described by Ambulacraria hypothesis, then gill slits are an ancestral feature for deuterostomes. These gill slits are supposedly lost in in lineage but some researchers have found evidence for gill slits in extinct carpoid echinoderms. The Ambulacraria hypothesis unites echinoderms and hemichordates on the basis of a…

1. What is alula? - Alula is a set of feathers on the first digit of birds which permits a slot on the wing. 2. What is crop milk? – Crop milk is a secretion from the lining of crop of parent…

It is easy to see how Darwin could have imagined that legs or arms would have been closely related to wings or fins; Behe attempts to render this line of thought obsolete, this explanation is too simplistic for the complex structures existing in biology. Again this is where Behe argues in favour of an intelligent designer, though this evidence does very little to support the theory as it only proves that the biological microstructures that make up life as incredibly complex. Darwin understood…

Importance of Microbes Introduction It was long ago when Man realized that, along with animals and plants, he was also accompanied by some other organisms as well, and though which remained hidden from his eyes. Those organisms were unveiled by Anton Van Leeuwenhoek, who first saw the tiny organisms which accompanied Man through the lenses of microscope. Later it was found out that microorganisms inhabited each and every surface of earth, on man himself, or even inside him, resided under the…

SPECIATION AND ADAPTATION Speciation is the evolution of biological species this is according to the Sage’s English dictionary and thesaurus. It is the continuous change in the genes of an existing specie until a formation of the new specie arise altogether. It is a result of two specie groups ceasing to share allele such that the genetic differences grow to the point of speciation. Many scientists have come up with different theories in an attempt to define and explain speciation, though…

primitively social behavior of Euglossa cordata (Hymenoptera, Apidae, Euglossini): a view from the perspective of kin selection theory and models of reproductive skew. The evolution of social behavior is perhaps one of the most controversial topics of biology, since the emergence of such behavior implies the evolution of altruistic traits that reduce the chance of reproduction (fitness) of individuals, through Natural Selection ( Freeman & Herron, 2009). Currently, there are models that link…

For decades, scientists have conducted research on all living things; to help us determine what life is, what life does, and why things live. During life, several miraculous things take place, and among those things is change. Change that can start a chain reaction over decades, centuries, even millenia. We call these changes evolution. There are, however, several doubts in the minds of people; most commonly, those people who believe in the words of the Bible. If evolution is a real thing, then…

RELATIONSHIP BETWEEN SPECIES DIVERSITY AND SIZE Effect of Surface Area on the number of species in biodiversity. Yes, there is a relationship between species diversity and size, the smaller the habitat the less diversity of species there will be. Species diversity is the variety of organisms that make up a community It has two components: • SPECIES RICHNESS: is the total number of different species in the area • RELATIVE ABANDANCE: is the proportion each species represents in that certain…
