Answer:
The career in marine biology that appeals to me the most is aquatic science. Aquatic scientists use comparative studies, long term data, models, and theory to address a myriad of questions pertaining to water: water movement, water chemistry, aquatic organisms, aquatic ecosystems, movement of materials in and out of aquatic ecosystems, and the use of water by humans. This sounds very compelling to me.
Answer:
water (H2O); during the light-dependent reactions (the first half of photosynthesis), water does the following roles: it replaces used electrons, contributes hydrogen ions into the thylakoid space, and releases an oxygen molecule as a byproduct.
The four types of fossils are:
<span><span>mold fossils = (a fossilized impression made in the substrate - a negative image of the organism)
</span><span>
cast fossils = (formed when a mold is filled in)
</span><span>
trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.)
</span><span>
true form fossils= (fossils of the actual animal or animal part).</span></span>
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
False, common examples of pathogens are pollen and animal hair.
An antigen called an allergen causes the immune system to react in an excessively ferocious way to a perceived threat that would otherwise be harmless to the body. Allergies are the term for such reactions.
Technically speaking, an allergen is an antigen that, when exposed to atopic persons, can trigger an immunoglobulin E (IgE) response, resulting in a type-I hypersensitivity reaction.
The majority of Immunoglobulin E responses in humans are only activated in response to parasite infections. Some people, however, may react to a variety of widespread environmental antigens. Atopy is the name given to this inherited tendency. Non-parasitic antigens in atopic people cause erroneous IgE production, which results in type I hypersensitivity.
