Which scenario describes an interaction between two of Earth’s spheres?
Water flows from a stream to a lake.
Gravity moves rocks to another location.
Lions use energy to catch other animals for food.
Bears dig big holes in the ground to protect their young.
Answer:
The scenario that describes an interaction between two of Earth's spheres is "bears dig big holes in the ground to protect their young".
Explanation:
The Earth spheres include the biosphere, the hydrosphere, the geosphere, and the atmosphere. In this context, there is an interaction between two spheres: the biosphere and the geosphere, when a bear digs holes in the ground because a living organism that is part of the biosphere is modifying the structure and shape of superficial soil, which is part of the geosphere.
Which of the following are characteristics of the tundra biome? (Choose all that apply.)
much rainfall throughout the year
low biodiversity
very cold temperatures
lack of trees
A lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.
What is Tundra Biome?The polar ice caps and the boreal woodlands (also known as taiga), it is located. Extremely low temperatures and barren, icy terrain define the tundra biome. The arctic tundra and the alpine tundra are the two different forms of tundra.
The Tundra Biome: The Ice Deserts of the World. The tundra is the coldest biome, with an average annual temperature of less than 5°C and yearly precipitation of less than 100 mm, most of it snow.
Only a few number of plants and animals can even thrive on the tundra due to its extreme weather conditions. The Finnish term "tunturia" is where the word "tundra" originates.
Therefore, a lack of trees, a lack of biodiversity, and extreme circumstances are what most clearly identify the tundra.

What is the difference between a producer and a consumer? (Select all that apply.)
Consumers convert sunlight energy into fuel and producers cannot.
Producers convert sunlight energy into fuel and consumers cannot.
Consumers can make their own food energy and producers cannot.
Producers can make their own food energy and consumers cannot.
Answer:
B & D
Explanation:
Producers make
Consumers eat/use producers and/or what they make
Hope its right :)
The difference between a producer and a consumer is producers convert sunlight energy into fuel and consumers cannot and producers can make their own food energy and consumers cannot. Thus, option B and D are correct.
Who is considered as producer?All green plants which prepares their own food is considered as the producers. Decomposers are usually defined as as those organisms which converts the complex organic matter into simpler ones, hence consuming the required amount needed and liberating the left over to the environment.
The cycle goes on and helps in maintaining a state of between the living and the decaying particles and the producers, consumers and the decomposers are interdependent on each other.Consumers convert sunlight energy into fuel and producers cannot.
So, it can be concluded that, after the death of an organism (consumer), some amount of energy is consumed by the decomposers and the remaining is mixed with the environment.
Therefore, The difference between a producer and a consumer is producers convert sunlight energy into fuel and consumers cannot and producers can make their own food energy and consumers cannot. Thus, option B and D are correct.

All living things have internal that helps them carry out basic functions.
true
................................
Answer:
True
Explanation:
By the end of grade 2. All organisms have external parts. Different animals use their body parts in different ways to see, hear, grasp objects, protect themselves, move from place to place, and seek, find, and take in food, water and air. Plants also have different parts (roots, stems, leaves, flowers, fruits) that help them survive, grow, and produce more plants.
By the end of grade 5. Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction. (Boundary: Stress at this grade level is on understanding the macroscale systems and their function, not microscopic processes.)
By the end of grade 8. All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). Unicellular organisms (microorganisms), like multicellular organisms, need food, water, a way to dispose of waste, and an environment in which they can live.
Within cells, special structures are responsible for particular functions, and the cell membrane forms the boundary that controls what enters and leaves the cell. In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues or organs that are specialized for particular body functions. (Boundary: At this grade level, only a few major cell structures should be introduced.)
By the end of grade 12. Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. Feedback mechanisms maintain a living system’s internal conditions within certain limits and mediate behaviors, allowing it to remain alive and functional even as external conditions change within some range. Outside that range (e.g., at a too high or too low external temperature, with too little food or water available), the organism cannot survive. Feedback mechanisms can encourage (through positive feedback) or discourage (negative feedback) what is going on inside the living system.
A central feature of life is that organisms grow, reproduce, and die. They have characteristic structures (anatomy and morphology), functions (molecular-scale processes to organism-level physiology), and behaviors (neurobiology and, for some animal species, psychology). Organisms and their parts are made of cells, which are the structural units of life and which themselves have molecular substructures that support their functioning. Organisms range in composition from a single cell (unicellular microorganisms) to multi-cellular organisms, in which different groups of large numbers of cells work together to form systems of tissues and organs (e.g., circulatory, respiratory, nervous, musculoskeletal), that are specialized for particular functions.
Special structures within cells are also responsible for specific cellular functions. The essential functions of a cell involve chemical reactions between many types of molecules, including water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information, in the form of DNA. Genes are specific regions within the extremely large DNA molecules that form the chromosomes. Genes contain the instructions that code for the formation of molecules called proteins, which carry out most of the work of cells to perform the essential functions of life. That is, proteins provide structural components, serve as signaling devices, regulate cell activities, and determine the performance of cells through their enzymatic actions.

resistance to exploitation is a battle of wits with your captor
The statement is false because resistance to exploitation is not related to wits.
What is social exploitation?Social exploitation is understood as a social relationship in which some people are abused or used for the benefit of others due to their belonging to that category or status.
An example of social exploitation was slavery in which African blacks were used for different purposes during the colony because they belonged to indigenous communities in Africa.
In the example above, Africans had to submit to their captors by force and had no opportunity to oppose it because resistance to exploitation is not a matter of wits.
