Food prices increase when more farmland is converted to urban land. The correct option is D.

Farmland is land that is temporarily covered in agricultural crops (areas with numerous crops are only included once), temporary grazing or mowing meadows, market and kitchen gardens, and land that is temporarily fallow.

Urban development entails transforming a region into an urban state in a variety of ways, including physically, geographically, economically, and societally, through changes in population and land use.

Food security decreased agricultural output, and agricultural labor is only a few of the repercussions of turning farmland into urban expansion. Because there is less land available for crop cultivation as a result of urban growth, local food prices may rise.

Therefore, the correct option is D. Food prices increase.

Answer:

Charles Darwin proposed the theory of natural selection.

Answer:

Unbalanced= Fe + H2SO4 Fe2(SO4)3 + H2

Balanced with same coefficients in the same order= 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2

Explanation:

Balancing a chemical equation means having the same number of atoms of an element on the reactant side as on the product side in accordance to the law of conservation of mass. To do this, coefficients (number behind the element) are used.

In this question,the below balanced equation was given

2CO2 + 3H20 ---> C2H6O + 3O2

Four other unbalanced equations were also given to be balanced and see which will have the same coefficients in the same order as the template equation. Let's start balancing each equation.

1. FeCl3 + NH4OH ---> Fe(OH)3 + NH4Cl (unbalanced)

Atoms of nitrogen, hydrogen, oxygen and Chlorine are unequal in both sides. Hence, we have

FeCl3 + 3NH4OH ---> Fe(OH)3 + 3NH4Cl (balanced)

2. CH4 + O2 ---> CO2 + H2O (unbalanced)

Atoms of hydrogen and oxygen are unequal in both sides. We have;

CH4 + 2O2 ---> CO2 + 2H2O (balanced)

3. Fe + H2SO4 ---> Fe2(SO4)3 + H2 (unbalanced)

Atoms of iron, sulphur, and oxygen are unequal in both sides. Hence,

2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 (balanced)

4. PCl5 + H2O ---> HCl + H3PO4 (unbalanced)

Atoms of chlorine, hydrogen, and oxygen are unequal in both sides. Hence,

PCl5 + 4H2O ---> 5HCl + H3PO4 (balanced).

From the above balanced equations, it can be observed that; 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 has the same coefficients in the same order as 2CO2 + 3H20 ---> C2H6O + 3O2

That is, coefficient 2---- 3 ---- 1 ----- 3.

Taking into accoun the law of conservation of matter, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

In first place, you have the balanced equation:

2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

The coefficients of the balanced reaction in order are: 2 -3- 1- 3

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Considering the law of conservation of matter, you must balance the chemical equation.

For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

On the other side the coefficients located in front of each molecule indicate the amount of each compound for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Considering what was expressed above and the reactions given, the following balanced reactions are obtained:

The coefficients of each balanced reaction in order are:

Finally, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

Answer:

The correct answer would be - red fruit white flower (Rrff) and yellow fruit yellow flower (rrFf).

Explanation:

It is given that R is dominant over r and F is dominant over f.

So the possible combination of genotype for Red fruit = RR, Rr

or, Yellow fruit = rr

for Yellow flower = FF, Ff

and White flower = ff

The cross between the true-breeding plants one has red fruit and yellow flowers and the other has green fruit and white flowers

RRFF × rrff = F1 = RrFf (red fruit, yellow flower)

RrFf × rrff

Gametes rf

RF RrFf red fruit yellow flower

Rf Rrff red fruit white flower

rF rrFf yellow fruit yellow flower

rf rrff yellow fruit white flower

Thus, the correct answer would be - Recombinant offsprings - red fruit white flower, yellow fruit yellow flower

When teaching Processing, it is essential to design and organize learning experiences that align with local circumstances and provide practical applications.

Here is a suggested approach for teaching Processing, including traditional processing of raw materials, metal processing, and food processing, considering local circumstances:

1. Introduction and Contextualization:

Start by introducing the concept of processing and its importance in various industries. Provide examples of local raw materials, metals, and food products that undergo processing. Discuss the significance of processing in the local economy and its impact on society.

2. Field Trips and Industry Visits:

Arrange field trips to local processing facilities such as factories, mills, or food processing plants. These visits offer students firsthand exposure to different processing techniques and machinery. Encourage students to observe and interact with professionals in the field, asking questions and understanding the practical aspects of processing.

3. Hands-on Workshops:

Organize hands-on workshops where students can engage in practical activities related to processing. For example, set up a metalworking workshop where students can learn basic metal processing techniques like cutting, shaping, and welding. Provide guidance on safety measures and proper tool usage.

4. Local Case Studies:

Explore local case studies of successful processing businesses or initiatives. This could involve inviting guest speakers from local processing companies or inviting entrepreneurs who have started their own processing ventures. Students can learn about the challenges, opportunities, and sustainable practices in the local processing industry.

5. Project-Based Learning:

Assign project-based tasks that allow students to apply their knowledge of processing. For example, students could design and develop a prototype for a food processing machine or propose innovative methods to improve traditional processing techniques using local resources. Encourage creativity, critical thinking, and problem-solving skills throughout the project.

6. Community Engagement:

Encourage students to engage with the local community by organizing outreach programs related to processing. This could involve organizing workshops for local artisans or collaborating with local farmers to develop value-added food products. Such activities foster a sense of social responsibility and provide students with real-world experiences.

7. Assessment and Reflection:

Regularly assess student understanding through quizzes, assignments, and presentations. Encourage reflective practices where students can evaluate their own learning journey and identify areas for improvement. Incorporate feedback mechanisms to continuously enhance the learning experiences.

By designing learning experiences that incorporate field trips, hands-on workshops, local case studies, project-based learning, community engagement, and reflective practices, students will develop a holistic understanding of processing and its significance in their local context. This approach will equip them with practical skills, foster creativity, and promote an entrepreneurial mindset, preparing them for future opportunities in the processing industry.
