Cyanobacteria produce _______ from nitrogen gas as part of the nitrogen cycle. Only about _______ of Earth's water is available

to be consumed by humans or used for agriculture. Animals cannot consume nitrates directly. They must obtain nitrogen by _______ plants or other herbivore animals. _______ from forest fires and volcanoes, as well as the decay of dead plants and animals, causes a type of pollution from carbon oxides. One of the primary reasons that freshwater is unevenly distributed around the world is due to variation in amounts of _______.

Answer: ammonia

1%

consuming

combustion

rainfall

Plant and animal matter decay at the bottom of a body of water and become buried in sediments, forming kerogen. Plate tectonic forces can increase the pressure and temperature of the kerogen. This can cause hydrocarbons to release, and these hydrocarbons accumulate in underground reservoirs.

Answer:

Cyanobacteria produce _______ from nitrogen gas as part of the nitrogen cycle.

Only about _______ of Earth's water is available to be consumed by humans or used for agriculture.

Animals cannot consume nitrates directly. They must obtain nitrogen by _______ plants or other herbivore animals.

_______ from forest fires and volcanoes, as well as the decay of dead plants and animals, causes a type of pollution from carbon oxides.

One of the primary reasons that freshwater is unevenly distributed around the world is due to variation in amounts of _______.

Respond to the following based on your reading.

Briefly summarize how decomposition of plant and animal remains and plate tectonic forces can lead to the formation of fossil fuels.

Explanation:

ammonia

1%

consuming

combustion

rainfall

Plant and animal matter decay at the bottom of a body of water and become buried in sediments, forming kerogen. Plate tectonic forces can increase the pressure and temperature of the kerogen. This can cause hydrocarbons to release, and these hydrocarbons accumulate in underground reservoirs.

Please answer these
ruslelena [56]

Answer:

1 A prokaryote is a cellular organism that lacks an envelope-enclosed nucleus.

2 Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope.

3 Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

4 The plasma membrane.

Cytoplasm.

Ribosomes.

Genetic material (DNA and RNA)

5 Prokaryotes

How does possessing cilia, flagella, or a pseudopod directly contribute to the survival of a unicellular organism? A. By creatin
miskamm [114]

The correct answer is d. By causing movement of the organism.

Cilia, flagella and pseudopodia are structures used for movement and/or getting food. Cilia and flagella are very similar  in structure with the difference in their length (cilia-short flagella-long and how many of them are found on cells (cells  usually have hundreds of cilia while cells with flagella usually only have one or two of them). Pseudopodia is a cytoplasmic extension with the same function as cilia and flagella.

What is the most unusual characteristic of food webs in agroecosystems?
pickupchik [31]

In agroecosystems, farmers practice monoculture. It is a practice of growing one type of crop in the same field year after year. Monoculture is an attempt to check herbivores from eating crops. As a result population of herbivores get reduced from the food webs. Using different types of agro-chemicals such as insecticides, pesticides, weedicides also reduces number species. Therefore, the most unusual characteristic of food webs in agroecosystems is lack of biodiversity.

How is the ATP produced in glycolysis like earning a return on an investment ?
telo118 [61]

Glycolysis is the first step of cellular respiration - the process comprised of series of reactions in which energy is extracted from glucose molecules. The process of glycolysis is almost same in all living organisms.

If we quickly overview the process of glycolysis, we see that it is a process of earning ATPs as a return on ATP investment, why?

  • 2 ATP molecules are invested during the first or preparatory phase pf glycolysis.
  • 2 ATP molecules are formed for each glyceraldehyde 3-phosphate molecule. Therefore, total four ATP molecules are produced.
  • Other than ATP, 1 NADH + H+ is also produced for each molecule of glyceraldehyde 3-phosphate.

Therefore,total amount of 2 NADH and  4ATP molecules are produced.

But since, there was an investment of two ATPs during the preparatory phase of glycolysis. Therefore, a total of  4-2=2 ATPs is formed/ So it is like an earning on an investment.

Hope it help!
