What are the smallest structures that biologists consider to be living?
Cells are the smallest structures of an organism. (nothing simpler than a cell is considered to be alive)
Why are spores refractile?
Retractile means that the object in question is good at bending light, or refraction. Spores have structures that vary in density compared to the whole. This allows them to be very easily studied under light microscopes.
At the end of mitosis 2 each parent cell becomes what numbero of gametes?
You mean meiosis. At the end of meiosis II, each diploid parent cell produces four haploid cells. In males, all four will become gametes called sperm cells. In females, one of the four haploid cells will receive the vast majority of cytoplasm and will become the female gamete, which is an ovum or egg cell. The other three cells will be reabsorbed.
Why do chromosomes line up in the middle of the cell during metaphase?
It is important that chromosomes move during mitosis because the chromosomes' sister chromatids need to separate. They must separate to become daughter cell-carrying chromosomes themselves.
What organic molecules studied today are present in cells?

What did the post World War 2 independence movements in India and Africa have in common?
Several key figures in the movements had studied in Great Britain or the United States.
Why aren't bacterial cells suitable for studying the stages of mitosis?
Mitosis is type of cell division which is found in Eukaryotic cells .It is different from cell division of bacteria which is not mitosis, but called amitosis or binary fission.Mitosis is actually nuclear divisionwith 4 stages i,e. prophase , metaphase , anaphase and telophase . Mitosis can be studied only in Eukaryotes , as Bacteria are prokaryotic which lack mitosis , hence they can`t be used for study of mitosis. ..
When a biochemist is studying the process of how a protein chain is assembled Which of the following cellular structures would be studied?
The ribosomes would be studied, because that is the site of protein synthesis.

yes they are, I studied this in college

What types of objects can be studied with a light microscopes. what types can be studied with an electron microscopes?
Light microscopes are used to study living organism and to watch and analyze their structures. Electron microscopes use a dead specimen and are able to observe structures in great detail and with much much higher magnification. +++The electron microscope has a far higher definition and magnification than an optical microscope could achieve, but as you say you could not use it to study a living organism.
What is the present perfect tense of study?
'have studied' or 'has studied' I have studied you have studied (singular) he, she or it has studied we have studied you have studied (plural) they have studied Some examples (using abbreviations) are: I've studied more than enough science. The trainees have really studied hard. She has studied just enough to pass the test.
What does the fluorescent microscope view?
The fluorescent microscope only views light of wavelengths equaling the fluorescing material that's being studied. If you have a dark background, cells and their structures can be glowing when seen.

In Asia, the mantis is considered lucky and a good omen, and was studied by Shaolin monks, who developed a fighting style based upon its movements.
What did the Maya study from observation?
The Maya studied astronomy, calendrics, agriculture, and the movements of celestial bodies from observation. They built impressive observatories and used their knowledge to develop sophisticated calendars and accurately predict celestial events.
