The male chiton releases his sperm cells into the water‚ and the female chiton releases her cells individually. As a result‚ fertilization is external. b. Not much changes

During this era‚ bronze‚ cast from alloys of copper‚ tin‚ lead‚ and other elements‚ was employed tremendously for dynamic compositions‚ displays of the nudity‚ and graphic expressions of individual identities. Surpassing marble with its tensile strength‚ reflective characteristics‚ and capability of embracing the finest details‚ bronze statues were produced

Lori Stenbeck Bio K121 June 7‚ 2012 The Microscope Introduction: The purpose of a microscope is to see either enlarge images of small objects and or make seen what is invisible to the naked eye. We have two types of microscopes available in the lab. The dissecting microscope is designed to study objects in three dimensions at low magnification. The compound microscope is used for examining small or thinly sliced sections of objects under magnification that is higher than the dissecting microscope

For as long as I can remember‚ I have been fascinated by marine life. I visited the Baltimore Aquarium many times as a child; I remember being amazed by the different kinds of animals I saw. I spent my summers at the library reading about marine organisms‚ their habitats‚ their adaptations‚ and how they interacted with other organisms. In middle school‚ I participated in a project that consisted of decorating the classroom to represent a biome‚ and I worked on the marine biome. In the summer before

CLASSIFICATION OF SEDIMENTARY ROCK Sedimentary rocks are classified according to two(2) major classes known as: • Clastic (detrital) Sedimentary Rocks • Chemical Sedimentary Rocks Clastic (detrital) Sedimentary Rocks 1. Made up of mineral grains‚ fragments of other rocks (called lithic fragment)‚ shells and other inorganic(hard) of formally living organisms. 2. The clastic particles or grains in a sedimentary rocks are cemented together by mineral precipitates that formed during the

The answer is‚ EUTROPHICATION: a complex process which occurs both in fresh and marine waters‚ where excessive development of certain types of algae disturbs the aquatic ecosystems and becomes a threat

Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect of diatoms is that when they die they hold onto CO2 trapped inside their silicon skeleton‚ carrying it to the ocean floor instead of being released into the atmosphere. d.

with the phenomenon known as an algal bloom. These algae fall into two categories. The first category of harmful algae produces toxins that are released when ingested by animals or humans. The dinoflagellate Alexandrium tamarense (left) and the diatom Pseudo-nitzschia australis (right) are examples of toxin producing alga. The other category of harmful algae kill without toxins. These are equipped with structures such as spines and serrated edges that allow them to lodge in fish gill tissues

Researchers of the University of Gothenburg shows that eutrophication of the seas may have an impact on genetic variation of the algae. The genetic variation of the algae may be affected by eutrophication. Different population of a diatom species has different growth and adaptability characteristics from one another. 16) Subject:Marine phytoplankton declining: Striking global changes at the base of the marine food web linked to rising ocean temperatures Marine phytoplankton
