1. State the parts of the cell theory and who actually came up with the facts that certain types of organisms have cells. 2. Are you prokaryotic or eukaryotic? Explain your answer. 3. If you became too large certain things may happen in your body as such as cells. Explain why cells can’t become too [...]
1. What is the smallest unit of life?
2. Robert Hooke and Anton van Leeuwenhoek helped to discover the cell and invented what?
3. Leeuwnhoek called the animals he discovered in the pond animalcules. Today they are kown as what?
4. How did Matthias Schleiden contribute to the cell theory?
5. What is the cell theory?
6. Most cells are [...]
In the nucleus, there is an organelle called the nucleolous. This is the very dark area in the nucleus. This organelle makes ribosomes—which make protein. Where do you find ribosomes in the cell (two places). Why is protein important for the body. Where do you find alot of protein on the body?
The mitochondia is called the energy organelle of the cell. Would the heart of the kidneysa have more mitochondria? Explain your reasoning.
An international team of biologists has discovered a new species of microsporidia, a single-celled parasite of animals, in a roundworm used in genetic laboratories around the world.
The discovery is a breakthrough for public health researchers who until now had been looking for a suitable laboratory model in which to study microsporidia—a class of emerging pathogens [...]
The nucleus is the control center of the cell. In the cell you will find DNA in the nucleus. During cell division the DNA (cromatin) begins to twist and begome very thick—chromosomes are now made. Why is DNA, cromatin, and chromosomes very important to you? Explain in detail.
The U.S. Department of Energy Joint Genome Institute (DOE JGI) has released a complete draft assembly of the soybean (Glycine max) genetic code, making it widely available to the research community to advance new breeding strategies for one of the world’s most valuable plant commodities.
New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT.
Using computer modeling and a variety of advanced chip-manufacturing techniques, they have applied an antireflection coating to the front, and a novel combination of multi-layered reflective coatings [...]
Why do some species of birds lay only one egg in their nest, while others lay 10 or more?
A global study of the wide variation among birds in this trait, known as the “clutch size,” now provides biologists with some answers. The study, published in the current issue of the journal PLoS Biology, combined data [...]
This week you will have an opportunity to turn off all the lights in the room and view jello using flashlights. There are specimen moving around in the jello, what does this represent in the cell? What does the liquid gel of the jello represent in the cell compared to the cell?
