Explain why it is important to monitor ecosystems over long periods of time?
Answer:
Biodiversity monitoring is important because it provides a basis for evaluating the integrity of ecosystems, their responses to disturbances, and the success of actions taken to conserve or recover biodiversity.
Monitoring keeps us informed, helps us to maintain our health, and alerts us to future problems that may arise. Monitoring ecosystems is similar to monitoring human health. ... Ecosystem monitoring means measuring physical, chemical, and/or biological variables over time to provide information on ecosystem change.

Using the idea of a concentration
gradient, explain why the blue
colour gradually spreads throughout
the water in the jar. When does
diffusion stop?
Answer:
Explanation:
Osmosis. Osmosis is the diffusion of water through a semipermeable membrane down its concentration gradient. If a membrane is permeable to water, though not to a solute, water will equalize its own concentration by diffusing to the side of lower water concentration (and thus the side of higher solute concentration).
do organisms use all potential energy they consume
Answer:
Yes, organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Scientists know that some methods used to increase the food supply are dangerous to humans. Which method is known to be harmful to human health?
A. Using genetically engineered crops
B. Spreading pesticides with planes
C. Increasing the number of vertical farms
D. Increasing the number of rural farms
Answer: Spreading pesticides with planes
Explanation: The use of pesticides has allowed the world’s food production to expand greatly over the last century. However, the chemicals in pesticides can be dangerous to humans and animals.
Pesticides also add chemicals and poisons to the plants and crops, which, if taken by people, can result in fatal diseases, allergies, malnutrition, and other ailments, hence option B is correct.
How are pesticides harmful to human health?A special chemical known as a pesticide is added to the agricultural field to protect the crops from harm caused by disease-carrying bugs.
While protecting the plants from pests that spread illness. Some farmers abuse pesticides without understanding the proper concentration to apply in their fields.
As a result, the population of humans and animals will experience more of the negative consequences of chemicals and poisons.
Therefore, spreading pesticides with planes to increase the food supply is dangerous to humans.

What things do humans do in the flower garden that alter the biotic elements of
the ecosystem? What effects do they have on biodiversity?
Answer:
Humans often use pesticides to destroy undesirable organisms that live in flower gardens, such as insects, weeds, or fungi. The use of such chemicals will reduce biodiversity. Humans also plant many of the same plants in gardens, which reduces biodiversity.
Humans perform different functions in the flower garden that alter the biotic elements of the garden, which include the usage of most of the pesticides that affect the soil and the microorganisms present in it, the planting of non native species, etc.
What is the significance of human interference in the garden?Human interference in the garden has many negative impacts, such as the introduction of non-native plant species to a garden, which can lead to the replacement of native plants, excess watering and fertilizing lead to an overgrowth of certain species and create an imbalance that changes the naturalness of the garden.
Hence, humans perform different functions in the flower garden that alter the biotic elements of the garden, which include the usage of most of the pesticides that affect the soil and the microorganisms present in it, the planting of non native species, etc.

A person walked 3 miles north turns and walks 2 miles east. Calculate the persons distance traveled and the displacement.
Answer:
displacement
Explanation:
3.61
Distance travelled by the person is 3 + 2 = 5 miles. Displacement of the object is 1 mile.
What are distance and displacement?Distance is the actual length travelled by the body. Displacement is the shortest distance travelled by the body.
Total distance travelled by the thing. This is dependent on the entire route taken, not just the beginning and ending locations. Travel distance is usually a positive quantity. a scalar quantity with the following units.
A change in an object's location. We write "change" as "Delta xx delta," where "x" stands for displacement. a vector quantity.
Therefore, the Distance travelled by the person is 3 + 2 = 5 miles. Displacement of the object is 1 mile.

in the lung model how does the air move and out of the smaller balloons
Answer:
The plastic at the bottom of the balloons act like diaphragm , as it expands air move in throw the straw which represent trachea and when it contract, the air move out the balloons.
Explanation:
In the lung ballin model, the plastic at the bottom acts as the diaphragm. Diaphragm is a strong muscle that expand and contracts that cause air to flow in and out of the lungs. The movement of the balloon matches with breathing. When someone breathe in, air moves into the lungs like the balloons and it is because the diaphragm/plastic expands and these make air to enter through the straw which represent trachea and when you breathe out, the diaphragm contracts which allow air to move out.

Cells contain small specialized structures called___________that act just like organs in your body
Answer:
Organelles
Explanation:
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.
Cells contain small specialized structures called organelle that act just like organs in your body.
What are cell organelles?An organelle is a subcellular structure that, like an organ, has one or more specific jobs to do in the cell.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.
The major organelles and cellular structures found within the cytoplasm include the nucleolus, nucleus, ribosome, vesicle, rough endoplasmic reticulum, Golgi apparatus, cytoskeleton, smooth endoplasmic reticulum, mitochondria, vacuole, cytosol, lysosome, and centriole.
The nuclei, which store genetic information, mitochondria, which produce chemical energy, and ribosomes, which assemble proteins, are among the more important cell organelles.

8. Alexander was studying the effect of playing rock music on plant growth.
One of the plants was exposed to rock music for 24 hours a day for a
period of 6 weeks. Data on the growth of the plant was collected at
the end of each week and plotted in a graph. Based on the data,
which would be the MOST reasonable measurement at the end of an
8-week period?
A. 2 decimeters B. 6 decimeters
C. 8 decimeters D. 16 decimeters
Answer:
C. 8 decimeters
Explanation:
As seen on the graph, the height of the plant is located on the y-axis while the period of growth or time in weeks is located on the x-axis. If you observe closely, the plant has an average growth of 1 decimeter per week.
week 1 = 1 decimeter
week 2 = 2 decimeters
week 3 = 3 decimeters
week 4 = 4 decimeters
week 5 = 5 decimeters
week 6 = 6 decimeters
week 7 = 7 decimeters
So, this means that at the end of the 8-week period, the plant's height is at 8 decimeters.
