All chemical equations must be balanced. This means that the same number of atoms
of each of the elements must be found in both the reactants and the products of the reaction. Which scientific law does this illustrate?
Law of Reflection
Law of Conservation of Energy
Law of Conservation of Mass
Law of Superposition
Answers
Answer:
The Law of Conservation of Mass.
Explanation:
The reasoning behind this is that when the chemical equation is balanced, so is the amount of mass. We make sure that the chemical equation is balanced to ensure that the law of conservation of mass is conserved. This is why we add coefficients to the beginning of reactants and products to make sure that the mass of the reactants combined is the same amount of mass of the products combined.

Turgor pressure is the pressure exerted on a plant cell wall by water. When wilted plants are placed in water, they demonstrate increased turgor pressure and become straighter. What is occurring at the cellular level when plants display increased turgor pressure?
Answers
Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them. When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
An adequate supply of water.The formation of osmotically substances.A semi-permeable membrane.Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Answer:
When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.'

The current device design will cost $I0,000 to manufacture, but the cost ofthe item cannot exceed $8,000. How should the engineer approach this problem using the engineering design process?
Answers
Answer:
the engineer needs to consider alternatives for all of the areas of the design process that are considered costs
Explanation:
In order to accomplish this, the engineer needs to consider alternatives for all of the areas of the design process that are considered costs. This includes materials, marketing, manufacturing, etc. Many times the material that is being used alone can skyrocket the cost of making a specific product. Therefore changing to a new material may lack some of the wanted benefits but will reduce the overall cost. Manufacturing techniques can also drastically reduce costs by simplifying the process you save on electricity costs and worker wages, while still outputting the same amount of product, which in term reduces the overall costs of the item.

light energy?
A. splitting carbon dioxide into carbon and oxygen
B. splitting water into hydrogen and oxygen
C. combining hydrogen and oxygen to form water
D. combining carbon and oxygen into carbon dioxide
Answers
Answer:
c.
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
The process of photosynthesis that is dependent on light energy involves splitting water into hydrogen and oxygen. The correct option is B.
What is photosynthesis?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
The main purpose of photosynthesis is to transform solar energy into chemical energy, which is then stored for later use. This mechanism primarily provides energy to the planet's life systems.
The light-dependent reaction of photosynthesis begins with the absorption of solar energy by pigment molecules.
Chlorophyll an is the most prevalent and plentiful pigment. To begin photosynthesis, a photon enters photosystem II.
Four significant stages make up a light-dependent reaction: the absorption of light energy, the splitting of water molecules, the release of oxygen, and the synthesis of the energy-carrying molecules ATP and NADPH.
Thus, the correct option is B.

Answers
Answer:
Diminuição do colesterol bom (HDL), aumento do colesterol mal (LDL)
Explanation.
Esto debe revertirse, debe ser una disminución del colesterol malo y un aumento del colesterol bueno.
Básicamente, el ejercicio aumenta el HDL y reduce los triglicéridos. En condiciones normales, los ejercicios aeróbicos no reducen el LDL. Sin embargo, cuando se combina con cambios en la dieta y una pérdida de peso bien controlada, el efecto combinado podría reducir el LDL.
En las condiciones estándar, el ejercicio recomendado por semana es de 150 minutos de ejercicios suaves o 75 minutos de ejercicio vigoroso por semana.
Por lo tanto, cuando se calcula por semana, esto sería un promedio de 20 minutos de ejercicio por día.
Andar en bicicleta, caminar, hacer jardinería y aeróbicos acuáticos son ejemplos prácticos de ejercicios leves o moderados que podrían aumentar el HDL. Sin embargo, el baile aeróbico, el trote y el salto de cuerda son ejemplos de ejercicios vigorosos que, cuando se combinan con la dieta y la pérdida de peso, conducen a una disminución del LDL.
This should be reversed, it should be a decrease in bad cholesterol and an increase in good cholesterol.
Basically, exercise boosts the HDL and lower triglycerides. Under normal conditions, Aerobic exercises do not reduce LDL. However, when combined with dietary changes and well-monitored weight loss the combined effect could lower LDL.
Under the standard conditions, the recommended exercise per week is 150 minutes of mild exercises or 75 minutes of vigorous exercise per week.
Therefore, when calculated per week this would be an average of 20 minutes of exercise per day.
Biking, walking, Gardening, and water aerobic are practical examples of mild or moderate exercises that could boost HDL. However, Aerobic dancing, jogging, and rope jumping are examples of vigorous exercises which when combined with dieting and weight losses leads to a lowering of LDL.

Answers
Answer:
Practice that provides the best means of protecting biodiversity in the wild for future generations is - expanding breeding programs for endangered species .
Explanation: The best way of preserving biodiversity for future generations in the wild -
Expanding breeding programs for endangered species . -: Breeding programmes, such as the panda, help conserve endangered species. Replanting hedgerows because there is greater biodiversity in them than the fields they surround, minimizing deforestation and the release of greenhouse gases, protecting and creating new endangered ecosystems, often by making National Parks.The other statements are not so suitable means of protecting biodiversity in the wild for future generation as the first statement indicates about the initiation of recycling programmes in neighborhood , which has no role in preservation of biodiversity or wildlife because the statement is about keeping the environment clean and healthy .
The other statement is about reduction of air pollution as buying vehicles with reduced carbon emissions improves the quality of air.
And the other statement of Protecting wildlife areas such as national parks comes under the other statement which states "expanding breeding programs for endangered species".
Hence , the correct option is D.

Does respiration expend more energy than photosynthesis?
Answers
Answer:
Explanation:
Photosynthesis vs Cellular Respiration Photosynthesis and cellular respiration are two basic metabolic processes occurring in the energy conversion of ecosystems. During photosynthesis, carbon dioxide and water are used in the synthesis of organic compounds with the aid of sunlight. This organic compounds can be used by cells as food. During cellular respiration, energy in the form of ATP is produced by breaking down food. The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.

D The development of the two types of forests has positively affected populations of shrubs by increasing the amount of sunlight in the area.
Answers
Answer: Option C.
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs
Explanation:
The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs because pine and hardwood are huge trees bigger than shrubs and occupy space. As they occupy space the received most of the sunlight, their roots is very extensive and draw water and nutrients from the soil which makes these resources not very much available for shrubs and hence it drastically affected the populations of shrubs. Because of their heights, wideness and big leaves, little sunlight gets to shrubs and hence shrubs photosynthesis is reduced.
The removal of one seral stage to another is called ecological succession.
The place which is used by the shrubs is now used by the tree and give the competition for the land. The development of the two types of forest has negatively affected the populations of shrubs by decreasing the amount of space available for shrubs.

Ecological success is valuable to understand, because it can change the biodiversity within an ecological community. Being able to teach a topic to a peer can demonstrate mastery! Explain the sequence of events that occur in secondary succession as you would to a friend who had not yet learned about the process.
Answers
Answer:
Secondary succession is a process in which a given area is disturbed, being re-colonized by other organisms following this process.
Explanation:
Secondary succession steps:
1- An area suffers a disturbance (e.g., fire, flood, earthquake, etc).
2-The process of disturbance destroys the food chain by removing primary producers (e.g., plants)
3- The vegetation grows back (i.e., first grasses and after higher trees). This process is known as recolonization
The secondary succession can regenerate an ecosystem in less than 50 years after disturbance. The first species re-established during secondary succession are the animals capable of living in disturbed habitats.
Secondary succession refers to the re-grow of species and the establishment of new ones in areas where a perturbation occurred leaving fertile good soil.
---------------------------------
Succession is a term used to refer to colonization and subsequent changes.
Colonization drives the establishment of individuals, populations, species, or bigger groups in areas where they were absent before.
When talking about succession, we refer to changes produced in the composition and structure of communities after a perturbation.
When a perturbation occurs -like fires, floods, earthquakes- and removes part or all of the aerial vegetable life forms, we talk about secondary succession.
In secondary succession, after the perturbation occurrence, the soil remains good and fertile, carrying viable spores, seeds, and roots of surviving species.
With time these species emerge and re-grow, colonizing the area. Also, new species can arrive at the open space, establishing there for the first time.
So, step by step,
1) A perturbation must occur in a community.
2) The perturbation damages or eliminates aerial parts of vegetable species. But the soil, which remains fertile, managed to protect seeds, spores, and roots of the species that used to live in these areas.
3) With time, these species regrow, and new species arrive in the area.
4) A new community emerges.
