Which two generalizations can be made based on what you know about cycles of matter in a closed system?
1 New matter is added, and old matter is destroyed.
2 Matter changes its physical form, allowing it to return to its original state.
3 The amount of matter within the system remains the same.
4 Matter and energy can cross the boundaries of the system.
5 The cycle has a well-defined starting and stopping point.
Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.
A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.
In a closed system, the cycle has a well-defined starting and stopping point.
Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)
The statements 3 and 5 can be two generalization made by the information of a closed system.
Explanation:A closed system is system in which neither matter nor energy cannot cross the boundaries of the system.So the statement 3 which is the amount of matter remains same in the system is correct one on the bases of the law of conservation of mass.This law states that neither mass and energy can be created nor destroyed but they can change from one form to another form.In the given system, reaction of matter is in cyclic form, the starting and stopping points of reaction can be well defined on the basis of reaction.what is a specific region of an enzyme where a substrate binds and the chemical reaction occurs
The correct answer is an active site.
The active site, in biology, refers to the region of an enzyme where the molecules of substrate combine and goes through a chemical reaction. The active site comprises of the residues, which produce temporary bonds with the binding site (substrate) and residues that catalyze a reaction of that substrate, that is, the catalytic site.
Active site is a specific region of an enzyme where a substrate binds and the chemical reaction occurs.
Explanation:The active site is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.

A researcher investigates a recently discovered species of plant. The plant has vascular tissues and exhibits a sporophyte and a gametophyte generation, but lacks seeds. How should the researcher classify the plant?
A. bryophyte
B. angiosperm
C. pteridophyte
D. gymnosperm
- It can't be a bryophyte because bryophytes are non-vascular.
- It can't be an angiosperm because angiosperms produce seeds.
- It can't be a gymnosper because gymnospers also produce seeds.
So, this means it's a pteridophyte because pteridophytes produce sprores insted of seeds, are vasuclar (meaning they have a vascular tissue).

Imagine an ecosystem with the following populations.
Level of Food Chain Types of Organisms
1.Producers
berry bushes
fruit trees
oak trees
maple trees
2.Primary Consumers
rabbits
mice
squirrels
crickets
ants
grasshoppers
3.Secondary Consumers
foxes
owls
Final answer:
The ecosystem described includes producers like trees and bushes, primary consumers such as rabbits and insects, and secondary consumers including foxes and owls, showcasing the transfer of energy through food chains from the sun to herbivores and carnivores.
Explanation:
Understanding the Ecosystem Food Chain
The ecosystem described involves a hierarchy of organisms from producers to consumers defining their relationships in a food chain. At the base, producers like berry bushes, fruit trees, oak trees, and maple trees capture sunlight to produce energy. These producers are consumed by primary consumers, including rabbits, mice, squirrels, crickets, ants, and grasshoppers, which are herbivores feeding on plants. Moving up the chain, secondary consumers such as foxes and owls, are carnivores that predate on the primary consumers.
In this structured ecosystem, each level of the food chain depends on the organisms below it for energy. Producers harness energy from the sun, primary consumers feed on this generated biomass, and secondary consumers feed on primary consumers. This energy flow demonstrates a basic but crucial ecological concept: the transfer of energy from the sun through various trophic levels up to carnivores.
The described system is a simplified presentation of a complex food web where multiple predators and prey interactions can exist. In the real world, organisms often consume from different trophic levels, making the food web an intricate network of energy transfer contributing to the ecosystem's stability and sustainability.

A gas with constant temperature has a pressure of 123 kPa and a volume of 123.13 L. A pressure change caused the volume to decrease to 28.15 L. What is the new pressure?
T = const.
P1 = 123 kPa
V1 = 123.13 L
V2 = 28.15 L
P2 = ?
This is an example of Boyle’s law which describes how the pressure of a gas tends to increase as the volume of the container decreases, meaning that P*V=const. For comparing the same substance under two different sets of conditions, the law can be expressed as P1*V1=P2*V2
P2=P1V1/V2
P2=123kPa*123.13L/28.15 L
P2=538.01 kPa

microbes are also the foundation of what that feeds all life on earth?
The microorganisms are the foundation of all forms of life on Earth, they have prevailed for about 3.5 billion years. The animals, plants, and the modern microbes have all evolved from the primitive bacteria. The life on Earth relies on their activities. According to the human's point of role, one could not survive in the absence of microorganisms.
The microbes demonstrate numerous benefits like the production of oxygen, nitrogen fixation, degradation of substances (like sewage, wastewater, and cellulose). Microbes play vital roles in the biosphere, the economic uses of microbes take place in the field of agriculture, industry, bioremediation, and medical microbiology.
Microorganism are also the foundation of Food chains that feed all life on earth.
Explanation:A microorganism, or microbe, is a microscopic organism, which may exist in its single-celled form or in a colony of cells. Microorganisms facilitates plants in fixing nitrogen.The convert waste organic compounds to carbon, oxygen and nitrogen for use by plants.Hence plant are primary source of food for almost all animals on earth.They are also indirectly providing food to some animals.What structures on the ventral side of the planaria propel it forward?
Cilia are the structures on the ventral side of the planaria that propel it forward.
Planaria is a type of flatworm that belongs to the class Turbellaria. Some species of planaria are terrestrial, while some are aquatic. Planarians have a soft and ciliated body. Cilia are hair like organelles situated on the ventral dermis of the planarians. Cilia function for locomotion by propelling the planarians forward, and allowing them to move smoothly on a layer of mucus.
During respiration, a seed metabolizes sugars. what is the source of the sugar metabolized by the seed?
The source of the sugar metabolized by the seed is photosynthesis.
The procedure used by plants to transform light energy into a chemical form of energy is known as photosynthesis. The chemical energy can afterward be discharged to fuel the plants to perform their activities.
During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates). However, the prime component generated in the procedure is glucose (sugar) that is the molecule, which generates energy to mediate the activities of the cell.
The source of sugar metabolized by the seed during respiration is the stored carbohydrates in seeds and bulbs, which are converted into simple sugars like sucrose. Once the seed starts growing, the plant can produce its own food through photosynthesis.
Explanation:The source of the sugar metabolized by the seed during respiration is the carbohydrates stored in seeds and bulbs. These carbohydrates, such as starch, are converted into simple sugars like sucrose through metabolic processes. Once the seed starts germinating and new shoots and leaves grow, the plant can produce its own food through photosynthesis.

From approximately 240 to 66 million years ago, dinosaurs dominated most of the land habitats on Earth. Around 66 million years ago, most dinosaurs went extinct when an asteroid struck the Earth. Mammals, which were much smaller and lived primarily in underground habitats, were able to avoid extinction. Mammals then underwent an adaptive radiation to develop a wide variety of new species. Which statement best explains why the adaptive radiation of mammals was possible?
A.
New species were able to form because the change in environmental conditions increased the mutation rate of mammals.
B.
Populations of mammals were able to rapidly increase since the Earth had a single, large habitat after the asteroid hit.
C.
Mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
D.
The loss of predation decreased the rate at which mammals became reproductively isolated from one another.
The correct answer is option C, that is, mammals were able to diversify to make use of the variety of habitats that were previously occupied by dinosaurs.
Adaptive radiation refers to the comparatively fast evolution of various species from a single common ancestor. Adaptive radiation usually takes place when a species enters a novel area and distinct traits influence its existence. An illustration of adaptive radiation is the progression of mammals after the annihilation of dinosaurs.
