Answer:
b. Vitamin K deficiency inhibits the blood’s ability to clot.
Explanation:
The main form is vitamin K1 (phylloquinone); followed by vitamin K2 (menaquinone), formed from the bacterial action on the large intestine tract and a third compound, vitamin K3 (menadione), a synthetic fat-soluble molecule. These vitamins can be found in many foods: in green vegetables (lettuce, cauliflower and spinach), in tomatoes, Brazil nuts, cashews, potatoes, contained in soybean oil, egg yolk, milk and to a lesser extent in wheat and oats.
Vitamin K participates in blood clotting, its deficiency can make it difficult to stop bleeding. Also causing damage to the body when in excessive concentration, for example: dyspnea (shortness of breath), and chest pain in adults with high vitamin K1 disorder and hyperbilirubinemia in newborns whose mothers in gestation underwent treatment with based on vitamin K3.
Answer:
The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.
Explanation:
Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:
- rapid growth of Algae and other plants
- due to algal bloom, the sunlight is blocked, and plants and organism start dying.
- The decomposers take up most of the oxygen by decomposition
- The animals start dying without oxygen
Answer:
There is no question, so what are we supposed to answer?
A mineral is a naturally occurring inorganic solid that has a fix chemical composition.
Another naturally occurring solid substance is Rocks.
Rocks are different from the Minerals as they are composed of several minerals and have different proportion of chemical compounds present in them along with some organic components also.
Explanation:
- Minerals have a fix chemical composition and are classified as metallic minerals, non metallic minerals and mineral fuels.
- Minerals are of immense use as they are the source from which pure elements can be obtained.
- Some examples of common minerals are Magnetite an ore of irone, Bauxite an ore of aluminium, Limestone, coal an example of mineral fuel.
Typical methods of classroom scientific communication depending on the level of study could include a range of these activities which have been listed in the answers. However, at the elementary, middle, and high school levels it would be safe to argue that the typical methods of communication are B) lectures, lab reports, term papers, and poster presentations. At higher levels would some of the other methods of communication be used such as scientific journals, oral presentations, lectured, conferences, etc.
