and the last water dissolve many kinds of minerals

The characteristics of water can be responsible for mechanical weathering is that water expands when it freezes. The correct option is B.

Weathering by Mechanical Means Rocks crumble as a result of mechanical weathering, also known as physical weathering and disaggregation.

Water, whether liquid or solid, is a common mechanical weathering agent. Liquid water, for example, can seep into cracks and crevices in rock.

Mechanical weathering includes processes like water freezing and expanding in cracks, as well as temperature changes that expand and shrink individual minerals enough to break them apart.

One of the most essential types of mechanical weathering is the freezing of water in rocks. Water expands by 9% when it freezes. If it completely fills a crack, the crack will expand.

Thus, the correct option is B.

Science teachers consider practical sciences to be a valuable component of science education for several reasons:

Hands-on Learning: Practical sciences provide students with the opportunity to engage in hands-on learning experiences. This approach allows students to actively explore and manipulate materials, conduct experiments, and make observations.

Example: In a biology class, students may conduct a dissection of a preserved specimen to study the anatomy and structure of organisms. By physically dissecting and examining the different organs and systems, students gain a tangible understanding of the subject matter.

Application of Theory: Practical sciences enable students to apply theoretical knowledge acquired in the classroom to real-world situations. By engaging in practical activities, students can bridge the gap between abstract concepts and their practical applications, fostering a more comprehensive understanding of scientific principles.

Example: In a chemistry class, students might perform experiments to understand chemical reactions and concepts like stoichiometry. By actually mixing and observing different substances, measuring quantities, and analyzing the results, students can see how theoretical concepts translate into practical applications.

Development of Scientific Skills: Practical sciences help students develop essential scientific skills, such as critical thinking, problem-solving, observation, data analysis, and communication. Through practical activities, students learn to formulate hypotheses, design experiments, collect and analyze data, draw conclusions, and communicate their findings effectively.

Example: In a physics class, students could design and conduct an experiment to investigate the relationship between force and motion. By planning the experiment, taking measurements, analyzing the data, and presenting their findings, students enhance their scientific skills and develop a deeper understanding of physics concepts.

Engagement and Motivation: Practical sciences often increase student engagement and motivation in science education. Hands-on activities provide a more interactive and dynamic learning environment, making science more interesting and accessible to students. It can spark curiosity, promote active participation, and cultivate a sense of wonder and excitement about the natural world.

Example: In an environmental science class, students may visit a local ecosystem to conduct field observations, collect samples, and analyze the data they gather. By immersing themselves in the real environment and actively participating in the scientific process, students are more likely to be motivated and engaged in their learning.

Answer:

This question is incomplete; but from the understanding of the question, it is about identifying the variables in the experiment e.g independent variable, dependent variable, control variable, control group etc.

The variables are as follows:

Independent variable: HEAT at different temperatures

Dependent variable: GROWTH OF MOLD

Constants/Control variables: Same amount of food, Same type of food

Control group: Jars kept at 0°C

Explanation:

A variable in an experiment are those factors that are subject to change. The INDEPENDENT VARIABLE in an experiment is that variable that is manipulated or controlled in order to bring about an outcome. In this Sarah's experiment, the independent variable is the HEAT CHANGE.

The DEPENDENT variable is the variable that responds to the changes made to the independent variable. The response of the dependent variable is dependent on the independent variable. In this experiment, the dependent variable is the GROWTH OF THE MOLDS because it responds to changes in heat (independent variable).

The CONSTANT or CONTROL variables in an experiment refers to the variables that are kept constant or unchanged throughout the experiment. Although they are not part of the experiment but they can affect the outcome of the experiment if changed. The constants in this experiment are the SAME AMOUNT and SAME TYPE OF FOOD given to each jar.

A CONTROL group is the group that does not receive any experimental treatment I.e. In this experiment, the jars placed at 0°C did not receive any heat, hence, they are the control group.

The experimental groups were the jars kept at 90°C and 27°C respectively.

Answer:

Question 1):   2) they have a relationship to each other.

1. Photosynthesis and cellular respiration are often described as been chemically opposite because THE PRODUCTS OF ONE PROCESS ARE THE REACTANTS OF ANOTHER AND VICE VERSA.

The reactants of cellular respiration are glucose and oxygen and these happen to be the products of photosynthesis also. During the process of photosynthesis, plants take in carbon dioxide and water in the presence of sunlight to produce glucose and oxygen. During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water, which are the reactants of the photosynthesis process.  

2. Photosynthesis and cellular processes are related to each other, this is because, the photosynthesis process produces the glucose, which cellular respiration used to synthesis energy in the cells of living organisms. Thus, the glucose producing plants depend on the living organisms that carried out cellular respiration to produce carbon dioxide and water, which is the necessary reactants for photosynthesis process. The organisms using cellular respiration also depend on plants to produce glucose and oxygen for their use.

Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.

Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.

The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.

The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.

While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.

In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.
