Biomes/natural Vegetation: Needle-leaf Evergreen Forests

Needle-leaf evergreen forests are largely comprised of straight trunked, conical shaped trees that have comparatively shorter branches with narrow and small needle like leaves. These forests are composed of conifers predominantly. Where the needle-leaf forests are evergreen, they provide continuous deep shade to the ground, therefore, the lower layers of vegetation are either absent or sparse (Veregin 2005). Only a thick carpet of mosses can be found below the needle-leaf biome. There are very few species that can be found, however the large tracts of the vegetation have one or two species. According to the World Vegetation Map, this ...

1. DNA in forensic science: DNA contains the genetic code of a person. The genetic information stored in the DNA, is coded in the form of nucleotide sequence. The nucleotide sequence is formed by four fundamental nucleotides: A, T, G, C nucleotide, that formed a polymer in a set order. A typical human DNA, has 3 billion nucleotide bases. The DNA sequence is 99.8% identical in all human beings and is only 0.2% dissimilar. This dissimilarity is the basis for identification of the suspects in forensic medicine. No two human beings can have a DNA that is 100% identical. ...

Introduction

Even though the concept of evolution is a typical narrative, it remains one of the most highly contentious of the topics. Major disagreements persist in the field, particularly when the evolutionary origin and physical modification of primates are the subject matter of discussion. Because of these differences, lots of significant finds in the field have attracted considerable amounts of opposition from experts depending on the species, or the side angle of evolution one recognizes (Ravosa and Dagosto). Disputes often center around locomotion and posture – whether a particular species was fully upright or could walk bipedally, brain size (intelligence), sexuality ...

Introduction

In the recent past, many scientists have provided evidence on how global warming that result from greenhouse gases may adversely affect the arctic regions (including tundra biome). These scientists argue that the excess abundant of greenhouse gases will cause global warming of the earth's climate in the near future. This global rise in temperature is more likely to damage the Antarctic and Arctic biome that than all other biome. This is because global warming is expected to shorten arctic tundra's winters and melt snow that covers permafrost. As a result of this, there will be flooding in many coastal areas. ...
