life. LGT and Descent Homology is one aspect of evolution and an important proof of evolution. Homologies are similar structures or genes in different species. For example‚ a human being’s arm‚ a dog’s leg and a bird’s wing all have identical bones structure. It supports that they have a common ancestor and separated into different species through evolution. Among homologies‚ homologous sequences can be created by horizontally acquired variations and vertically generated variations. Horizontally

field-based whole organism biology in an area with little human interferences. Method 1. Lay a horizontal transect on the mid-shore (1.75m) 2. Repeat for high-shore (2.25m) 3. At regular intervals of 1m on one of the transects record the number and species of each organism found within that quadrat. 4. Repeat at the same interval for the other transect. 5. Repeat at each interval. Conclusion Based on the data I have collected‚ I conclude that there is a greater biodiversity on the mid shore than

The Palearctic forms have a uniformly dark brown or black background wing color with one major band of white pigment running across both the dorsal and ventral surfaces of the wings. Variations among these species is predominately subtle in variations of this white-band wing pattern. In contrast‚ wing patterns in Nearctic forms are diverse. There are three lineages of mimicry in admiral butterflies that occur in North America which may have played a large

HOLD THE FUTURE: PRESERVING THE PHILIPPINES BIODIVERSITY The sum of all the different species of animals‚ plants‚ fungi‚ and microbial organisms living on Earth and the variety of habitats in which they live is called Biological Diversity or also known as the Biodiversity. Scientists estimate that upwards of 10 million—and some suggest more than 100 million—different species inhabit the Earth. Each species is adapted to its unique niche in the environment‚ from the peaks of mountains to the depths

relentless competition with the workingmen of the world‚ but handicapped by a training the very opposite to that of the modern self-reliant democratic laborer"(Dubois 21). The idea of fair competition that is discussed in Darwin’s On The Origin of Species is not in this society as people are not given a fair opportunity to succeed. This idea of a just chance of survival has been destroyed "after the brains of the race have been knocked out by two hundred and fifty years of assiduous education in submission

DEFORESTATION AND ENDANGERED SPECIES IN MALAYSIA Malaysia has a diverse number of animal and plant species in its rainforests. 20% of the world’s animal species are found here. These forests cover two-thirds of the Malaysian land. It has about 250 species of reptiles‚ 150 species of snakes and a thousand species of insects. There are around 14‚500 species of flowering plants and trees. Besides the rainforests‚ Malaysia has 1‚ 425 sq km of mangroves. However‚ with the current rate of deforestation

Food Chain: A sequence that links species by their feeding relationships. Herbivores: Organisms that only eat plants. Carnivores: Organisms that only eat animals. Omnivores: Organisms that eat both plants and animals. Detritivores: Organisms that eat detritus‚ or dead organic matter. Specialist: A consumer that primary eats one specific organism. Generalist: Consumer that has varying diet. Trophic levels: The levels of nourishment in a food chain. Food Web: Shows the network of feeding relationships

Our goal was to observe the effects of the competition in each instance.The first one was to observe the intraspecific competition between the wheat plant species‚ the second was for the intraspecific competition between the mustard plant species. The third was the interspecific competition of the wheat and mustard species together. The latter experiment’s

concept - which‚ granted‚ is a big one. Biodiversity: Life‚ the world‚ the variation of life for the entire globe. It’s a big idea with a long history. Biodiversity found on Earth today consists of many millions of distinct biological species‚ the product of four billion years of evolution. But the word “Biodiversity” itself is actually quite new. "Biodiversity" was coined as a contraction of "biological diversity" in 1985. Clever eh? And as politicians‚ scientists‚ and conservationists
