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.

Does the light independent pathway of photosynthesis continue to occur when the leaf disks are placed in the dark environment
Yes, the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.
What is photosynthesis?“The process by which green plants make their own food in presence of sunlight, chlorophyll and carbon dioxide is called photosynthesis.”In this process oxygen molecule is released as by product.It has two pathways: light dependent and light independent.
In light dependent pathway, light energy is used by chlorophyll and is converted into chemical energy.In light independent pathway, the energy produced during light dependent pathway is used to convert carbon dioxide into carbohydrates. It occurs in the stroma of the chloroplast.Hence, it is true that the light independent pathway of photosynthesis continues to occur when the leaf disks are placed in the dark environment.

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.

since they normally have an internal salt concentration of 0.9% salt. Which statement best explains why the cells shrink?
Sall causes the cell membrane to swet and absorb water trom the cytoplam
Sat moves from the 8 sal solution into the cell and chemically bind with water
Water moestrom the cell through the cell membrane to an area of lower water concentration
O Water moves from a lower concentration of water in colis cytoplasm into the nucles and colorganelles
The cell shrinks because of the movement of water away from the cell into the more concentrated salt solution.
Osmosis is the movement of water from one region to another through a semi - permeable membrane. A hypertonic solution contains more solute than the cell.
In this case, the external salt solution is hypertonic because it contains a 8% salt concentration whereas the cell contains only a 0.9% salt concentration. As such, water moves out of the cell into the solution.

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.
