30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
Answers
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.

In the atmosphere, 50% of the air lies below an altitude of 89.0000655.
What do you mean by altitude of atmosphere?Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth's surface, the exosphere is the highest layer of Earth's atmosphere and, at its top, merges with the solar wind.
The commonly accepted end of earth's atmosphere falls within the thermosphere at 62 miles (100 kilometers) above the earth's surface. This commonly accepted boundary is called the Kármán Line.
The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor.

Has the herd reached its carrying capacity for this
ecosystem? How do you know?
O a. The herd has reached its carrying capacity
because the growth rate is negative.
Ob.The herd has reached its carrying

Answers
Answer:
Choice: (A) The herd has reached its carrying capacity because the growth rate is negative.
Explanation:
The herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.
What is ecosystem?Ecosystem is defined as a ecology's structural and functional unit where living things interact with one another and their surroundings. Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They provide tools and raw ingredients for producing medicines and other goods. Major elements of many ecosystems include plants, animals, insects, microorganisms, rocks, soil, water, and sunlight.
Clumps can disperse in a region when there is an unequal distribution of resources like food, water, moisture, temperature, or other materials. More food supplies are available, finding a mate requires less migration for individuals, and organisms are better protected from predators.
Thus, the herd has reached its carrying capacity because the growth rate is negative. Hence option a is correct.

1. How do you think rapid changes in the chracteristics of habitats affect the niches of
animals occupying that habitat?
Answers
Answer:
The rapid changes would make an organism change their land, environment around them, and the food web
When the habitat of the animals living in it changes, both the animals and the habitat change. It changes the biotic and abiotic factors of the niche and ecosystem. Habitat is part of a niche.
What is the impact of the changing habitat?
Niche is a broad space in which the particular animal roams, searches for food, and reproduces, but habitat is a part of the niche where the animal spends most of its life. Human interventions, such as cutting down forests for industry, roads, and so on, have an impact on wildlife. Due to this, the temperature of the earth keeps on increasing, resulting in climate change, global warming, the melting of ice, a rise in water levels, etc.
If these changes happen, then animals will have difficulty living in their habitat. The environment will not be favorable for living, and both abiotic and biotic factors will be disturbed, such as the fertility of the soil, which is affected by fewer trees. Other animals affect by this change too.
Hence, in this way, the change in habitat changes the niche.

how does air pressure affect weather
Answers
Answer:
Hewo, Kiluawa (sorry if i spelled it wrong)
Explanation:
High Pressure
Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.
Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.
Low Pressure
On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.
Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.
In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.
