The dodo, which is also named Raphus cucllatus, is an extinct bird that has the disability in flying. Accordingly, dodos are very likely to be eaten by Dutch sailors as they are extremely easy to be caught. It is also mentioned that dodos became more and more scarce after the sailors have landed on the island in 1598. The fundamental reason that cause the extinction…

Hydrosphere the earth. It includes oceans, lakes, seas,
Hydrosphere The hydrosphere is the liquid component of the earth. It includes oceans, lakes, seas, ponds, rivers, and streams. The hydrosphere cover up almost 70% of the earth’s surface.Lithosphere The lithosphere is the solid, outer part of the Earth. The lithosphere includes the upper bit of the earth’s mantle and crust, it is bounded by the atmosphere above and the asthenosphere.Atmosphere The atmosphere is a…
Many hence this is one tragic reason why
Many people normalize supporting animal cruelty each year and they may not know it. In today’s society “we” use these products not knowing that they’re being tested on animals. Imagine being defenseless not being able to help yourself, constant pain and suffering, well this is the harsh reality of what happens to millions of animals each year. These “experiments” do not benefit us like we…
Introduction action of drug classes which includes
IntroductionPharmacological ClassPharmacological class which is also known as drug class is a set of medications and other compounds that have same chemical structures. Examples would be Fibrate, Benzodiazepine, Cardiac glycoside to name a few. Second, drug classes is to have the same mechanism of action that share a common molecular by modulating the activity of a specific biological target and also include the type of…

1. There are reasons human activities can cause shortcomings in biogeochemical cycling. Fish kills can be caused by eutrophication and an increased growth of algae. Algae causes a loss of available oxygen, called anoxia. Anoxia can kill fish and other aquatic organisms. Algae does produce oxygen but only when there is enough light. Eutrophication reduces the clarify of water so in eutrophic lakes, algae is…

Animals
Animals: they have been used for centuries as a means of food, pleasure and everyday resources. This statement raises the question weather it is okay for humans to clone animals for our needs and wants. There have been many studies to show how cloning animals that are nearly extinct can help restore ecosystems that are dieing. Also, there are medical breakthroughs that show cloning animals…
unlight
unlight, water, temperature, food and air are the five basic needs that every living organism on earth requires to survive. However, factors called ‘limiting factors’ in a living organism’s environment can prevent it from surviving there. Limiting factors are described as an issue that limits growth, abundance, and distribution of a population of organisms in an ecosystem outside of their preferred niche (Biology Online 2018).…
POLLUTION OF THE ENVIRONMENT – the introduction of new
POLLUTION OF THE ENVIRONMENT – the introduction of new, not characteristic for it physical, chemical and biological agents or excess of their natural level. MAIN TYPES OF POLLUTION1. Physical (thermal, noise, electromagnetic, light, radioactive)2. Chemical (heavy metals, pesticides, plastics and other chemicals)3. Biological (biogenic, microbiological, genetic)Physical pollution is pollution associated with changes in the physical parameters of the environment. Depending on which parameters exceed the…
