Answer: transoceanic ships.

Explanation:

Zebra mussels are originally native of lakes in Russia and Ukraine.

They are ordinary found in the bottom of ships. For example in the ballast water of tansoceanic ships. So, it is likely that the zebra mussels adhered to those ships were accidentally introduced in the Great Lakes.

Zebra mussels are an invasice speicies so they a great concern for the ecology.

Some of the effects of Zebra mussels in the Great Lakes ecosystem, among others, are:

- they spread into streams and rivers throughout the US
- they cover the substrate of some areas
- they block pipelines
- they are believed to be the source of deadly avian botulism (responbile of killing birds)
- they are responsible for the near extinction of many species

Thiobacillus denitrificans is a species of bacteria that obtains its energy from carbon dioxide and inorganic compounds such as

tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.

sveta [45]

Answer:

Starch is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

Cellulose is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

Glycogen is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

How have scientists determined the earth's core is composed of iron and nickel?

Sedaia [141]

The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
To date materials the procedure of radiometric dating or radioactive dating is used, for example, rocks or carbon, in which trace radioactive impurities were specifically fused when they were framed. The strategy looks at the abundance of a normally happening radioactive isotope inside the material to the abundance of its decay items, which shape at a known consistent rate of decay.
