* NCERT 1. Reproduction in Organisms INTRODUCTION Biology in essence is the story of life on earth. While individual organisms die without fail‚ species continue to live through millions of years unless threatened by natural or anthropogenic extinction. Reproduction becomes a vital process without which species cannot survive for long. Each individual leaves its progeny by asexual or sexual means. Sexual mode of reproduction enables creation of new variants‚ so that survival advantage is enhanced

by the enzymes of bacteria and fungi that can spoil food. Benzoquinone reflects light of orange wavelengths and absorbs light of green wavelengths‚ which makes us measure enzymatic activity by measuring light absorbance. There is a hypothesis that enzyme kept at 37 degrees Celsius will show the most absorbance which shows most enzymatic activity. Also calcium and magnesium are hypothesized as the cofactors necessary in the functioning of enzymes in bacteria and fungi that spoil food‚ due to EDTA binding

microorganisms. Fungi‚ Protista‚ Bacteria‚ and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures‚ prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of eukaryotes. These eukaryotes then evolved into protists‚ fungi‚ plants‚ and animals

Microbiologist Microbiologists are scientists that focus on organisms that can sometimes cause infection. They study bacteria‚ fungi and viruses. They try and diagnose infections so that they can identify and characterise organisms. They have a big effect on the world as without them‚ we would have no cure for illnesses. A skill that a microbiologist requires is to be able to create a sample using one hand as this is more efficient and also vastly more productive than performing the procedure without

is a universal donor. Lymphocytes is a white blood cell that has a round nucleus surrounded by blue halo of cytoplasm with no visible granules. They have B cells that differentiate into cells that produce antibodies‚ T cells that attack viruses‚ fungi‚ transplanted cells‚ cancers‚ some bacteria‚ allergic reactions‚ natural killer cells that attack wide variety of infectious microbes and certain spontaneously arising tumor cells.2. Basophils are white blood cells that contain dense blue-purple granules

Coral & Coral Reefs Introduction Coral needs light to thrive and grow‚ but they grow faster in clean water. The largest coral reef in the world is the Great Barrier Reef located off north western Australia. This reef covers 135‚000 square miles. There are a wide variety of coral. They all have unbelievable fun facts‚ unusual habitats‚ unique characteristics‚ and interesting behaviors. Fun Facts There are many unbelievable fun facts about coral. Coral are small creatures‚ that often

Tortoises | Bacteria | Jumping Cholla | Water-holding frog | Fungi | There are three major categories of all living organisms’ producers‚ consumers and decomposers. Producers‚ also called autotrophs‚ in an ecosystem consist of mostly plants and some bacteria and algae that use photosynthesis to catch energy by sunlight‚ carbon dioxide‚ water to create carbohydrates. Consumers‚ also called heterotrophs‚ include animals‚ bacteria‚ and fungi that get their energy consuming other organisms. Decomposers

Fungal contribution in the etiology of infections has increased considerably. However‚ as medical technology has improved‚ The number of infections by intrinsically drug-resistant species has increased rapidly. Despite the constant introduction of new and effective synthetic drugs to the market‚ medicinal plants‚ which are the historical basis of therapeutic health care‚ represent an alternative that is economical‚ accessible‚ and applicable to various pathologies‚ particularly in developing countries

Have you ever thought about how many animals there were back then? We have been researching the 10 geological time periods and we found some interesting things. Like for example‚ there were many species of animals‚ plant‚ and fungi. There is one big question‚ has the amount of species gone up or down over time? Yes‚ I believe that the number of animals living on earth has increased over time‚ i believe this because scientist are finding new species of some sort‚ There is a lot of land that could

to act‚ there are a few factors that affect them which are: substrate concentration‚ temperature‚ salt concentration‚ pH‚ and inhibitors‚ activators and cofactors being present (Kumar‚ 2015) Finding the optimal temperature for amylase Bacteria and Fungi with the presence of starch is the purpose of this experiment. Optimal conditions are known as conditions in which organism are able to thrive in‚ where it is able to function at its best. If an organism was to surpass its optimal temperature‚ the
