The carrying capacity of an environment may be decreased by
Answer:
Carrying capacity can be decreased by disease, an increase in predation, hunting or harvesting by humans, a decrease in available habitat such as habitat destruction by humans, parasites, competition with another species for a resource, or changes in the weather that make the species less suited to the environment.
The carrying capacity of an environment may be decreased by increased activity of predators, diseases, climate change, human activities, habitat destructions, etc.
What is Carrying capacity?Carrying capacity may be defined as the maximum number of individuals that can be supported by a habitat.
The carrying capacity of the same habitat may be different for different species. It actually depends on how a species utilizes the resources present in that habitat.
The carrying capacity of any species in its habitat depends on the numer of predators, the flow of diseases, the influence of human activities like overgrazing, industrialization, harvesting, habitat destructions, etc.
Therefore, it is well described above.

Expalin the physiological concepts associated with muscular tissue at a microscopic level
Answer:
Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity. Muscle tissue has four unique characteristics, which include excitability, contractility, extensibility, and elasticity.
Explanation:
Muscle tissue has four distinct properties: excitability, contractility, extensibility, and elasticity.
What are muscles?The human body contains approximately 600 muscles. Skeletal, smooth, and cardiac muscles are the three primary types of muscle.
The neuromuscular system is the collaboration of the brain, nerves, and skeletal muscles to end up causing mobility.
Muscle fibers are highly specialized cells that make up the muscular system. Their main function is contractility.
Movement is governed by muscles, which are attached to bones or vital organs and blood vessels. Muscle contraction causes nearly all movement in the body.
Muscle tissue is distinguished by characteristics that enable movement. Muscle cells are excitable, meaning they respond to stimuli.
They are contractile, which means they can simplify and produce a pulling force. When muscles are attached between two movable objects, such as two bones, they contract.
Thus, these are the three physiological concepts associated with muscular tissues.

Arrows are labeled as follows: A from the sunlight to photosynthesis, B from carbon dioxide in atmosphere to photosynthesis, C from factory emissions to carbon dioxide in atmosphere, D from carbon dioxide in atmosphere to carbonates in water, E from dead organisms to fossils and fossil fuels, and F from plant respiration to the sky.
Using the diagram above, answer the following questions:
6. True or False. The arrow labeled C represents a transfer of chemical energy to mechanical energy. Explain why this is true or false.
7. True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
8. Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
9. Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
10. Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
From factory emissions to carbon dioxide in the atmosphere (C)
The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.
from dead organisms to fossils and fossil fuels (E)
The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.
from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)
Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure

the source of plant cells in the experiment. A sweet potato was diced into evenly sized andshaped cubes and placed
in beakers containing various glucose concentrations. The experimental setup is shown in the table here.
Which statements accurately predict the beaker in which water will enter the cells at a greater rate, causing an
Increase in mass for the sweet potato cells?
A)
Beaker 1
B)
Beaker 3
C) beaker 4
Answer:
A
Explanation:
Water will enter and leave the cells at the same rate via osmosis
The correct option is (A) Beaker 1 in which water will enter the cells at a greater rate, causing an increase in mass for the sweet potato cells.
What is Osmosis?Osmosis refers to a process in which the water or solvent diffuse across a semipermeable membrane (here cell membrane) from the area of high solute (here glucose) concentration to low solute concentration. The concentration of glucose in the water of beaker 1 is 1.5M which is highest as compared to other beakers.
The concentration of glucose solution in beaker 1 is hypertonic to the concentration of glucose in the cell which makes the water to move inside the cell via osmosis. Movement of water inside the cell results in increase in mass for the (sweet potato) cells.
Thus, the water will enter the cells at a greater rate in the beaker 1 because the glucose concentration is highest in the beaker 1 corresponding to its cell glucose concentration.
