why is a soda exploding/fizzing a physical change?

Answers

Answer:The fizzing of soda is a physical change that involves the release of gaseous carbon dioxide. During fizzing of a soda, you can see bubbles of carbon dioxide in the soda rise to the top. A bottle of soda doesn't fizz when it is closed because the pressure is higher, and keeps the carbon dioxide dissolved in the liquid.

Which of the following correctly describes how glucose becomes the product of a chemical reaction?
O Photosynthesis creates glucose using energy, a solid, and a liquid.
O Photosynthesis creates glucose using energy, a gas, and a liquid.
O Cellular respiration creates glucose using a gas and a liquid.
O Cellular respiration creates glucose using a solid, and a liquid

Answers

Answer:

[tex]\boxed {\tt B. \ Photosynthesis \ creates \ glucose \ using \ energy, \ a \ gas,and \ a \ liquid}[/tex]

Explanation:

Glucose is made in the process of photosynthesis. It is used in cellular respiration, but not made. So we can eliminate choices C and D.

Now, let's analyze the photosynthesis equation so we can pick between A and B.

6CO₂+6H₂O+light energy ⇒ C₆H₁₂O₆+6O₂

A gas (carbon dioxide), a liquid (water) and energy are used to make glucose and oxygen.

No solids are used, so we can eliminate choice A. We are left with choice B. Photosynthesis creates glucose using energy, a gas, and a liquid.

Large, circular lily pads are able to float on the water's surface.

Answers

Answer:

true

Explanation:

they're buoyancy

The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.

What is cohesion?

Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.

The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.

The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.

Thus, the property of water that is shown in the given statement is cohesion.

The five categories of adaptations are migration, hibernation, dormancy, camouflage, astivation.

What is migration?

The term migration has been defined as when the birds, animals, or human beings leaves the native place and move towards a new place due to weather or other physical condition is known as migration. Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

The stage of dormancy is the stage when seed gets closed and not able to germinate as it closes its outer wall. The term hibernation is defined as the particular time period in which the organism hybernate himself for a period of time when the weather or the outer environment is not safe, or fit for his survival.Generally, when it is too much cold the birds of that particular area migrated to the place where they found suitable temperature for their survival.

Select an ecosystem that is familiar to you and describe the biotic and abiotic factors that exist there?

Answers

Answer:

Forest Ecosystem

An ecosystem is composed of two main components: biotic and abiotic factors. Biotic factors are the living parts of the ecosystem, such as plants, animals, insects, fungi, and bacteria. Abiotic factors are the non-living parts of the ecosystem, which influence the size and composition of the living parts: these are components like minerals, light, heat, rocks, and water.

Biotic Factors by Type

The most obvious features of any forest ecosystem are its trees, the dominant biotic feature. They dominate the ecosystem: both in terms of visibility and in terms of biomass. However, they are only one type of organism living in a forest. Other biotic factors include:

shrubs , flowering plants , ferns , mosses , lichens , fungi , mammals , birds , reptiles , insects , worms , microbes

Abiotic Factors by Type

The most important abiotic feature of a forest ecosystem may not be obvious, despite its ubiquity and importance: sunlight. Tangible abiotic factors include soil, minerals, rocks, and water. But abiotic factors can be intangible, such as temperature, other types of radiation, and the chemistry of soil and water.

Biotic Factors by Function

Ecologists frequently group an ecosystem's factors by what role they play in the system, rather than by what particular species they are. This is known as a functional classification.

These functions relate to the movement of energy through an ecosystem, and trees — along with other photosynthetic plants — are the chief primary producers. This means that trees convert the sun's energy into food energy, which is then used by other members of the ecosystem.

These other members of the ecosystem can also be categorized. Primary consumers are, for example, herbivores that eat the primary producers. Secondary consumers are the carnivores and omnivores that eat the primary producers. Decomposers are the scavengers, microbes, and fungi that consume the droppings and the carcasses of other organisms.

Abiotic Factors by Function

The abiotic factors of a forest fall less obviously into functional classifications, but keep in mind that the energy transferred among the various biotic categories is itself a foundational abiotic element. This energy occurs in the form of solar radiation, which includes both visible light and heat (infrared).

Primary producers (plants like trees and shrubs) convert the light into carbohydrates, a form of energy that can be consumed by other organisms. The function of other abiotic factors relies on the minerals they contain, such as the nitrogen in the soil or the hydrogen in water molecules.

An ecosystem consist of various biotic and abiotic factors which interact with each other. A grassland ecosystem is a terrestrial ecosystem which have grass as the main producers (dominant) living thing.

What is a Grassland Ecosystem?

A grassland ecosystem is a type of terrestrial ecosystem in which grasses and the herbaceous plants are the dominant species. Grass controls the grassland ecosystems as they are the main producers of the ecosystem with few or no trees where there is not favorable conditions for a forest. It is more like a dry and desert ecosystem. Therefore, it is also called as a transitional landscape.

The four important abiotic components of grassland ecosystem includes climate, parent material and soil, topography, and natural disturbances. Climate includes the rainfall pattern, temperature and wind patterns of a particular area.

Biotic Factors in the Grassland ecosystem include Plants, Insects (Invertebrates), Grazers, and Predators.
