Millions of species inhabit Earth. How do scientists make sense of them all? First‚ scientists study the similarities and differences between organisms. The scientists study characteristics including obvious physical traits‚ such as hair or leaves‚ and molecular traits‚ such as DNA sequences. Then‚ scientists use the information to classify species into meaningful groups. The groups may also reveal which species are related and how they fit along the evolutionary tree. Scientists who specialize in

BIOLOGY 1010L – BOTANY Laboratory Module 8. Plant Physiology (2): Plant Pigment Paper Chromatography All organisms need energy for their metabolic processes. They also need “food” to produce that energy. Plants are autotrophs (self-feeders). Plants produce their food through a process called Photosynthesis. The food that they produce is the sugar glucose. Animals and other organisms are heterotrophs (other- feeders). They must consume other organisms (plants) in order to eventually get their

TURRITOPSIS NUTRICULA No brain‚ no stomach‚ no central nervous system‚ no respiratory system‚ no circulatory system...You would think jellyfish would be weird enough creatures. But nope. One species has taken "freak" to a whole new level with the ability to be‚ well‚ immortal. Meet Turritopsis nutricula‚ better known as the immortal jellyfish -- and sometimes known as the Benjamin Button jellyfish because of how it transforms itself from mature adult back into baby form in times of stress or

1. Introduction Ageing is the accumulation of changes in an organism or object over time and is usually mainly seen as a biological process‚ however there are many other factors that can affect the ageing process such as the psychosocial and behavioral factors. These influence heavily on the aged person and the life they live. If any of these components of aging are neglected or ignored then person couldn’t possibly sustain a healthy standard of living. 2. Effects Of Ageing- Psychosocial

constructed; there are also a lot of biological and genetic factors that contribute. Two biological factors that affect our gender roles are our genes and hormones. When a baby is first conceived it is genderless for the first seven weeks of development and‚ since there is no gender‚ the development for males and females during this period is identical. At seven weeks when the sperm and egg combine to form the zygote‚ the genes activate the babies’ biological sex. Everyone has 23 pairs of chromosomes

Human development is a very complex process – from conception to death. There has been a long debate on whether human development is determined by nature or nurture. If their growths were all guided by nature only‚ they would all be born with a mind of “blank slate”. This means that they do not have any inborn ability to do anything when they are born. On the other hand‚ if their growth was determined by nurture only‚ it would mean that they were fully equipped with all the skills they need in
