Not only for ourself, but for our further generations. As a teenagers, especially a college student, there are lots of things we can do to stop damaging our environment. Firstly, changing the way we think of our environment, facing the reality of our environment which have been seriously dam...
Living organisms need water to survive. ... All oxygen-dependent organisms need waterto aid in the respiration process. Some organisms, such as fish, can only breathe in water. Other organisms require water to break down food molecules or generate energy during the respiration process. What are...
One very common group of organisms seen in mulch and mistaken for fungi are the slime molds. They are not related to fungi, but do develop spores and have a mobile (plasmodium) phase where they can be seen to slowly move from one spot to another. Eventually, when the plasmodial stage is...
Some living things need sunlight to make food. Animals need oxygen to produce energy for their bodies. The environment must also have the right tcperature for organisms to survive. Without these non-living things, life would not exist (存在). Just like abiotic factors make it possible for ...
The extremes of this normal variation appear to be strongly driven by genetics, along with other features of circadian periodicity in humans; sensitivity to zeitgebers (environmental stimuli that synchronize the biological rhythms of organisms with their environment) has also been shown to be ...
food by converting carbon dioxide and water into sugar with the aid of the sun's energy viaphotosynthesis. Other autotrophic bacteria use chemicals such as sulfur to make energy in a process called chemosynthesis. The energy organisms need comes in the form of a molecule called ATP, oradenosine...
Describe how energy is stored in an ATP molecule? Why is cellular respiration beneficial for living organisms? Explain briefly the process that creates the majority of the ATP yield and why we need oxygen. Why, in eukaryotic cells, does an NADH from glycolysis result in only 2 ATP but in ...
Which macromolecule is the primary energy source for organisms? What are proteins? How can diversity of proteins in living organisms be explained? (a) What are proteins? (b) How can the diversity of proteins in living organisms be explained?
Primitive organisms behave in mainly reflexive and mechanistic ways as they respond to stimuli. Their responses are usually based on the value of the stimulus to the organism (good, e.g., an energy source, or bad, e.g., a noxious substance). As animals evolved to become larger, ...
Coral reefs are complex three-dimensional habitats where the sizes, shapes, diversity and composition of hard corals influence the overall reef structure,
