Answer:
1. Nitrification occurs when soil microbes convert ammonium into nitrate. Much of the overlap between the carbon cycle and the nitrogen cycle occurs in the soil, in processes conducted by soil microbes. Microbes break down nutrients, build new compounds for their own growth, and eventually die.
The second question im not sure sorry- the positive and negative one ;(
3. Many human activities have a significant impact on the nitrogen cycle. Burning fossil fuels, application of nitrogen-based fertilizers, and other activities can dramatically increase the amount of biologically available nitrogen in an ecosystem. As nitrogen makes up 78% of the atmosphere, there is no shortage of it – it just isn't in a form plants and animals can use.
4. Carbon makes its way through living things as carbon-based compounds, like energy molecules, fats and proteins, eventually cycling its way back into the atmosphere. Nitrogen is mainly found in the atmosphere as well and enters the ecosystems as nutrients for plants. Water, nitrogen and carbon cycles. Carbon moves from the atmosphere and back via animals and plants. Nitrogen moves from the atmosphere and back via organisms. Water moves on, above, or below the surface of the Earth.
5. Carbon cycle, Nitrogen cycle, Nutrient cycle, Oxygen cycle, Phosphorus cycle, Sulfur cycle, Rock cycle, Water cycle.
6. Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth's plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Earth's surface is the only habitat available to the human race. Understanding the processes by which that habitat has been created and continually altered is important to determine the causes of environmental degradation.

Chan Hee is inflating a basketball using an air pump. He notices that the pump gets warm as he uses it. What is a good
hypothesis that could lead to new experimentation?
If there is no air in a basketball, then it is hard to play the game.
A basketball that is inflated bounces better than one that is not inflated.
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Basketball is more fun to play than baseball because you have to move a lot more.
Answer:
If air in a pump is squeezed more, then the air gets hotter because energy is added to it.
Explanation:
A good hypothesis in the given case is that inflating basketball is getting warmer, the more it is pumped, and as a result, it would possess more heat or more friction due to all the air being pumped into the basketball at a single time.

One function of the poly-A tail on eukaryotic MRNA sequences is to help the MRNA be transported from the nucleus to the cytoplasm. Prokaryotic mRNA also has a poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.
Answer:
In eukaryotes, it is well known that polyadenylation is required to produce the mature messenger RNA (mRNA) molecule and it provides stability to the mRNA during translation initiation. In prokaryotic organisms, polyadenylation is required for the degradation of the mRNA in a mechanism that involves three steps: endonucleolytic cleavage, polyadenylation and exonucleolytic degradation. Moreover, it is also important to note that no evidence of polyadenylation has bee reported in some prokaryotes including the halophilic bacteria Haloferax volcanic (Slomovic et al. 2005).

define the ratio of sperm to egg?
Answer:
1,2 × 10⁹ : 1
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Explanation:
Therefore, a standard sperm to egg ratio of 1 × 105 sperm per egg is recommended for fertilization in Atlantic cod. At the 1 × 103:1, 5 × 103:1, and 1 × 104:1 sperm to egg ratios maximum fertilization occurred after 30 min sperm to egg contact time.

Hospital patients often receive medications, nutrients, and water intravenously (IV), which means they are injected directly into the patient’s veins through a needle. IV fluid is not pure water, but is instead a saline solution (water containing NaCl). What do you think is the appropriate NaCl concentration for IV fluid? Why?
Answer:
The answer to the following question is given below.
Explanation:
Saline includes 9 g NaCl dissolved in 1 liter of distilled water utilized primarily for sick people with moisturization.
This NaCl concentration has been presumed to be the physiologic concentration necessary for the restoration of vitamins and minerals by the body to control a suitable osmotic balance.
NaCl is mainly used to cover up the salt missing. In order to help nerves function properly, our bodies do require sodium.
The explanation regarding appropriate NaCl concentration for IV fluid is explained below:
The following information should be considered:
Saline involved 9 g NaCl that dissolved in 1 liter of distilled water utilized primarily for sick people with moisturization.

When multiple glaciers start their downward flow from a single point, they create a .
Answer:
They create a Mountain Peak
When multiple glaciers start their downward flow from a single point, they create a Mountain peak. So, the correct option is B.
What are Glaciers?A glacier is a sizable, slowly moving mass of ice that develops over a considerable amount of time as a result of the buildup of snow and ice. In areas where the average temperature is below freezing and there is enough snowfall to offset the melting that takes place during the summer, glaciers can be discovered. They can occur at lower elevations in some places, although they are mainly found at high altitudes or in the polar regions.
When several glaciers begin to flow downward, they build something resembling a pyramid. The mountain peak is created as a result of the glacier's movement from a single location. Due to the simultaneous movement of several glaciers to the ground, a pointed structure has recently created.
Therefore, the correct option is B.

When can exponential growth happen?
O A. When there is unlimited food and space
B. When the death rate is high
C. When carrying capacity is reached
D. When there is competition for resources
Answer: when there is Unlimited food and space
Explanation:
When there is unlimited food and space. Exponential growth occurs when a population has unlimited resources, such as food and space, and there are no limiting factors such as predation, disease, or competition for resources. In such a scenario, the population will continue to grow at an accelerating rate without reaching a carrying capacity. Hence option A is correct.
What is exponential growth?
Exponential growth can occur when there are no limiting factors that affect the population size. This means that the population has access to unlimited resources such as food, water, and space. In this scenario, the birth rate exceeds the death rate, and the population grows at an increasing rate over time.
As the population grows larger, the rate of growth also increases, resulting in a J-shaped curve on a graph.
However, in the real world, exponential growth is limited by factors such as predation, disease, competition for resources, and environmental factors like weather and natural disasters.
When these limiting factors are present, the growth rate of the population slows down, and the population may eventually reach a maximum size that the environment can support, known as the carrying capacity.
At this point, the population growth rate slows down to zero, and the population size stabilizes at or around the carrying capacity.
Hence option A is correct.
