Answer:

Dissimilatory- oxygen absent

Assimilatory- high concentration of nitrite

Explanation:

In assimilatory nitrate reduction, ammonium is produced and subsequently incorporated into biomass to build up e.g., proteins and nucleic acids. Dissimilatory nitrate reduction is a process for energy conservation, in which nitrate is used as an electron acceptor in the (near) absence of oxygen . Dissimilatory nitrate reduction and nitrate storage in particular are physiological life traits that provide microbes with environmental flexibility (i.e., metabolic activity under both oxic and anoxic conditions) and resource independence (i.e., anaerobic metabolism without immediate nitrate supply), respectively. Such life traits are especially important in environments that are temporarily anoxic and/or nitrate-free and they may have developed as a “life strategy” in both prokaryotes and eukaryotes

What types of cells have DNA? Where in the cell is it located
LuckyWell [14K]

Answer:

Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis? The L-
Yuliya22 [10]

Answer;

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

Explanation;

-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.

-The process takes place in two phases; light dependent stage and light independent stage.

-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.

-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.

What are some effects agriculture has on the water system?
madreJ [45]
Improper agricultural methods may elevate concentrations of nutrients, fecal coliforms, and sediment loads. increased nutrient loading from animal waste can lead to eutrophication of water bodies which may eventually damage aquatic systems.
