The statement is false because a plant dying from exposure to poison is an example of a chemical change, as it involves a change in the plant's chemical composition, not just a physical alteration.

The question: A plant dying after being exposed to poison represents a physical change, true or false?. False. This statement is false because a plant dying from poison represents a chemical change, not a physical one. This is due to the alteration of the chemical structure within the plant as a result of the poison, which causes damage or death to the plant. For instance, when a toxic agent like poison interacts with a plant's biological systems, it can lead to a series of biochemical reactions that ultimately cause the plant cells to die, a process that involves a change in the chemical composition of the plant.

Additionally, the terms chlorotic (yellowing of leaves due to lack of chlorophyll) and necrotic (dead tissue) refer to conditions that are symptomatic of underlying chemical changes within the plant tissues. Therefore, exposure to poison and the resulting damage is a clear example of a chemical change.

Answer:

The cell can be identify by looking at their shape.

Explanation:

Plant cells have cell walls outside the cell membrane. Animals cells doesn't have any cell wall.

The shape of plant cells are generally square or rectangle. The slide contains cells with square shape cells, that means the cells are plant cells. If the slide has oval or round shape cells , the cells are animal cells. Large vacuoles are visible only under the slides of plant cells.

Thus, the difference on the basis of cell shape and vacuoles can be used to identify plant and animal cells.

Cells are the living entities, which are the structural, basic, and functional units of all living beings. The eukaryotic cell can be divided into plant cells and animal cells.

The difference between the plant cell and animal cell are:

Thus, the person can identify the plant cell and animal by the presence of cell walls in the plant cell.

Developing a science question requires prioritizing testability and reliance on observable phenomena, ensuring meaningful contributions to scientific inquiry and knowledge generation. The correct answer is C. Ensuring it is testable and based on observable phenomena.

In developing a science question, the critical aspect lies in its ability to contribute to scientific inquiry and understanding. It should not merely conform to popular trends or aim for complexity to impress.

Instead, the question should prioritize testability and reliance on observable phenomena.

Firstly, a scientifically rigorous question must be testable. This means that it should be possible to design experiments or gather data that can provide evidence to support or refute hypotheses related to the question.

Testability ensures that the question leads to empirical investigation, which is fundamental to the scientific method.

Without the ability to test a question, it remains speculative and cannot contribute meaningfully to scientific knowledge.

Moreover, a science question should be based on observable phenomena.

This means that it should be grounded in real-world observations or measurable phenomena that can be studied systematically. By focusing on observable phenomena, scientists can gather empirical evidence to support their hypotheses and conclusions.

Observable phenomena provide the basis for constructing scientific models and theories that accurately describe and predict natural phenomena.

Contrary to the options presented, aligning with current popular trends or emphasizing complexity and technical jargon may detract from the scientific validity of a question.

Popular trends may be fleeting and not necessarily grounded in scientific inquiry, while complexity for the sake of impressiveness may obscure the clarity and coherence of the question.

Additionally, inundating a question with technical terms can alienate audiences and obscure the underlying concepts.

In summary, the critical aspect in developing a science question is ensuring it is testable and based on observable phenomena. This ensures that the question contributes meaningfully to scientific inquiry and facilitates the generation of reliable knowledge.

The correct answer is C. Ensuring it is testable and based on observable phenomena.

Scientific names are more useful because they refer to the same, identical organism regardless of place.

In theory, every recognized species on Earth have a two-part scientific name. This system is known as “binomial nomenclature”.

These names are important because they make it possible for people all around the world to communicate clearly about different animal species.

Scientists give each organism a name that is well known because the use of common names can be confusing (also known as a scientific name).

Common names differ throughout languages and even between areas of the same country. Additionally, various species could use the same common name.

Therefore, So every organism is individually classified without the worry of mixing up two organisms like a fly and Nat.

Answer:  circulate and move within a liquid or gas

Explanation:

hope it helped xx

In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

Convection currents arise by the difference in particle density in the fluid. Generally, warmer particles are less dense and tend to rise, while colder particles are denser and tend to do the opposite motion.

For convection to occur, a propagating medium, usually fluid (liquid or gaseous), must exist, because convection cannot move through empty spaces. This process of heat propagation happens due to the emergence of convection currents in the fluids.

This happens, for example, when heating water in the stove. The deeper molecules near the fire heat up faster, becoming less dense than the molecules closer to the surface.

All bodies emit energy by radiation at all times. At temperatures close to the environment, this phenomenon can usually not be perceived by human eyes, but can be seen when the body is at very high temperatures, such as a glowing ember.

Therefore, In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

Final answer:

The dew point is the temperature at which air reaches 100% relative humidity and water vapor condenses into liquid water. To find the dew point, we can use the relative humidity and the temperature. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point using these values.

Explanation:

The dew point is the temperature at which air reaches 100% relative humidity. It is the point at which water vapor in the air begins to condense into liquid water. For example, if the temperature is 20.0°C and the relative humidity is 39.0%, we can find the dew point by multiplying the relative humidity by the saturation vapor density and converting it to a temperature.

ATP, known as the energy currency of the cell, transfers energy to cell processes and releases that energy upon breaking the bond between its second and third phosphate groups. The correct option is b.

Explanation:

The correct statement about Adenosine triphosphate (ATP) is that it transfers energy to cell processes. ATP is often referred to as the energy currency of the cell, as it stores the energy derived from the catabolism of nutrients, like glucose and fats, and releases it to power various cellular functions. ATP consists of an adenosine molecule attached to three phosphate groups; when it is used for energy, the bond between the second and third phosphate groups is broken, resulting in the formation of ADP (Adenosine diphosphate) and a release of energy. This process is known as phosphorylation, where the third phosphate group is temporarily attached to another molecule, often to activate or deactivate it or to enable it to participate in a subsequent reaction. Hence, Option b is accurate.

The characteristics of life that best explains people having a stable internal body temperature is homeostasis. The correct option is C.

Homeostasis is the state of constant internal, physical, and chemical conditions maintained by living systems in biology.

This is the state of the organism's optimal functioning, and it encompasses many variables, such as body temperature and fluid balance, being kept within certain pre-set limits.

The tendency to resist change in order to maintain a stable, relatively constant internal environment is referred to as homeostasis.

Negative feedback loops are commonly used in homeostasis to counteract changes in various properties from their predicted values, known as set points.

Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.

It is the preservation of a constant internal environment in the face of changing internal and external conditions.

Evidence of low rainfall in a specific year can be identified through decreased agricultural outputs, thin tree rings indicating stressful growing conditions, and historical climate events associated with dry conditions such as the Little Ice Age.

Evidence of a year with low rainfall can be seen in several aspects of our environment. Some of the clearest indicators may be observed in agricultural output, tree ring records and historical climate events.

First, significant droughts can impact agricultural production sharply. For instance, in 2014, the Manchuria Plain in China experienced its intense drought in 50 years, resulting in a dramatic decrease in wheat, corn, and soybeans supplies. Thus, in years with low rainfall, we may expect to see a decline in the amount of agricultural products supplied at any given price.

Secondly, nature provides its own historical record through annual tree rings. These rings can reveal prevailing climatic conditions during each growing season. A thin ring usually suggests low rainfall or high temperature stress which impaired growth.

Lastly, major historical climate events, like the Little Ice Age in Europe in the fourteenth century is characterized by cold weather and, in some areas, droughts which reduced available food supplies due to low rainfall.
