Question about nitrogen and phosphorous cycle? Which statements are true, list all that apply

Biology

vaieri [72.5K]3 years ago
4 0

Answer: 1) When phosphorous is not bound in rocks, it moves quickly through land food webs. Constant use of phosphate-rich fertilizers will help increase phosphorus availability to plants, thus ultimately helping our ecosystems.

3) Minimizing the use of ammonia-rich fertilizers on lawns would not add excess nitrogen to the nitrogen cycle. As a result, it would help decrease the pollution of food webs in the oceans, decrease soil acidity on land, and decrease the amount of greenhouse gases in the atmosphere

Explanation:

The nitrogen and phosphorus cycles both are biochemical cycles. The nitrogen cycle involves the process of uptake of nitrogen from the atmosphere by the soil bacteria which is then become available to the plants for plant growth, from plants it is transferred to the other organisms in different forms.

The phosphorus is found in the rocks and these rocks wither and the inorganic phosphorus become available to the ecosystems.

Option 1 is correct, this is because the phosphorus is available on earth in the inorganic form inside the rocks, the withering and erosion processes make the phosphorus available to the plants. Another source of phosphorus to plants is phosphorus rich fertilizers. Thus plants will absorb phosphorus and grow. These plants will be consumed by other organisms thus the ecosystem will remain healthy.

Option 3 is correct, this is because nitrogen rich fertilizers can cause eutrophication in water bodies, or can contaminate the water. It will decrease the pH of the soil due to the formation of nitric acid. Also the nitrogen dioxide is the greenhouse gas.

The cell of humans contains 46 chromosomes and is about to undergo cell division. What type of cells are created after this?
Ghella [55]

Answer:

The cell of humans contains 46 chromosomes and is about to undergo cell division so two types of cells are formed. If the cell division occurs in somatic cells then mitosis occurs or if the cell division occurs in sex cells then meiosis occurs. In mitosis, two daughter cells are formed while in meiosis, four daughter cells are produced. In mitosis, each daughter cell has 46 chromosomes while in meiosis each daughter cell has 23 chromosomes.

Ostrovityanka [42]

Answer:

B: The shorter and more rounded the Appalachian Mountains are more than four times older than the taller and more jagged Rocky Mountains

Explanation:

  • The Appalachian mountains form a system of mountains in eastern North America and are older than rocky mountains as they were formed 480 million years ago and are similar to those of the alps. They form a barrier to the east to the west.
  • They extend to southeast Canada and form zones of 300 miles wide. They form the mountain ranges surrounding hills and the dissected plateaus forming at an elevation of 6,684 meters from the sea level. <u>Whereas the rocky mountains are younger and have an elevation of 4,401 meters.</u>
