Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)

Answers

Answer 1

Nitrogen is a limiting plant nutrient because the bulk of the available nitrogen in the atmosphere is not usable by plants.

Plants are not able to make use of the nitrogen in the atmosphere directly. Atmospheric nitrogen needs to be converted into usable forms before it can be accessed by plants.

The conversion of atmospheric nitrogen to usable form by plants is known as nitrogen fixation and this is achievable by the activities of certain bacteria.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.


A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.


Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question.


Part B - Whats the students scientific question?

Part C - Construct at least two possible hypotheses for the students experiment

Part D - Choose one hypotheses to make a prediction

Part E - How would you conduct your investigation? In your answer, explain your independent and dependent variables.

B- Do tomato plants grow faster and taller using natural compost or artificial fertilizer?

C- 1: Tomato plants grow faster in compost than in fertilizer. 2: Tomato plants grow taller in compost than in fertilizer.

D- Tomato plants grow taller in natural compost rather than artificial fertilizer.

E- First, I would plant three tomato plants in different pots. One would be full of natural compost, one full of artificial fertilizer, and one with regular dirt. Then, I would wait a few months, giving them the same amount of water each day, and record the results. The independent variables are the amount of time and water, while the dependent variable is the height of the plant after a few months.

F- My design includes a control group, being the plant with the plain dirt, as well as minimizing error by treating the plants with the same amount of water.

G- After a few months, I would record the height of all three plants and see if the tomato plants grown in natural compost or artificial fertilizer were taller.

The question can be solved by using the difference between eukaryotic and prokaryotic cell.Prokaryotic cell does not have a well defined nucleus. The nuclear material lies naked in the cytoplasm. It is known as nucleoid. While, eukaryotic cell has a well defined nucleus with a nuclear membrane.Prokaryotic cell has a single chromosome while eukaryotic cell has more than one chromosome.Finally, prokaryotic cell do not have membrane-bound cell organelles while eukaryotic cell have membrane-bound cell organelles.

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?


Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.


In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.


In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.


In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.


In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.

Answers

Answers: A,B,D

Explanation: :I took the test and got this question right .

The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.

In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.

Therefore the statement below about anaphase is correct.

Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.

In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.

That is, the cell now has 92 chromosomes which is enough DNA for two cells.

Therefore the statement below about interphase is correct.

In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.

In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.

The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.

Therefore the statement below about prophase is correct.

In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
