Introduction The interaction between genetic variation and natural selection is one of the most important concepts in modern biology. The product of this interaction, evolution, which is a change in a populations allele frequency, is responsible for the great complexity and diversity of life seen on earth today. Allele frequencies of a non-evolving population (one…

The subject I will cover is lipids. I will tell you about the description of it s organic compound. I will tell you where it is found. I will tell you what the uses are in plants and animals. I will also tell you about its chemical structure and give examples of types of these…

1. In a multi-cellular organism, the activity of the entire organism depends on the total activity of its independent cells. 2. Explain Biogenesis and Abiogenesis. Biogenesis is the idea that living organisms develope only from other living things and not from non- living matter. Abiogenesis is the erroneous idea that life can arise spontaneously from…

When studying the grass under a microscope, you can see the chloroplasts containing chlorophyll, which from the Greek language is literally translated as a “green leaf”. This pigment has a green color and gives it to all plants. Under the influence of sunlight in plants, photosynthesis takes place, the main role in which it is…

Prokaryotes have three principal structures which are posts, cocci and winding. The bacterial cell divider is irrefutably the most essential supporter of cell shape. Alive and well of cell divider, closeness or nonappearance of flagellum, and if appear, spots of flagellum, the eubacteria can be requested by Gram Stain. Above all, gram positive tiny creatures…

The plant rhododendron belongs to the family Ericaceae which also includes the Heath, and there are about eight-hundred fifty species which grow worldwide (Turner and Szczawinski, 171-2). The Heath family is a large one with so many species, all of the poisonous species fall into two of its subfamilies, one of which is the rhododendron….

Hormones are organic substances that are secreted by plants and animals and that function in the regulation of physiological activities and in maintaining homeostasis. They carry out their functions by evoking responses from specific organs or tissues that are adapted to react to minute quantities of them. The classical view of hormones is that they…

Enzymes are a biological reaction that remains unchanged, most enzymes are chemical of hydrogen peroxide which changes that release energy and build new materials for cells and tissues. Each enzyme has its own specific shape, but without enzymes, the digestive system will take weeks and weeks to digest food. When the enzyme changes shape it…

Several people have puzzled over this question. There is no one single answer to this. Several factors contribute: Tropisms, environment, hormones, biological clocks, and even humans. We are trying to determine the effects of music on plants. It takes all these combined to have a plant that actually grows and a plant that is healthy…

The ability to reproduce human beings without sexual reproduction is no longer only an idea to be explored in sci-fi movies and books. After over forty years of research and development, human cloning is quickly becoming a reality. Cloning captured the publics attention when Scottish scientists startled the world in July of 1996 when they…
