Changes to an environment, such as drought or human activity, can reduce the available resources. What do you predict might happen if resources were to become reduced or unavailable?
Answer:
Animals and Human may die
Explanation:
If your talking about natural resources etc trees which give oxygen might not be here (The oxygen will still be in the air for awhile, but it may run out) Animals and us humans may suffocate or starve. Than we have the plants which we use for food or medicine. They wouldn't be here either and we wouldn't be able to take care of ourselves safely and go unharmed.
A person's basic material necessities for a happy existence, health, positive social relationships, security, and their freedom of choice and action are all impacted by changes to ecosystem services.
What are resources?A resource is an element or component of the environment that an organism needs for healthy development, maintenance, and reproduction in biology and ecology.
One organism's consumption of resources may make them unavailable to other organisms.
Human welfare and ecosystem services have a nonlinear relationship. A marginal increase in environmental services often makes only a small positive impact on human well-being when supply is abundant compared to demand.
However, a little reduction in the service's availability can have a significant negative impact on people's well-being.
Similar to trees, plants provide us with food and the oxygen we breathe; if they disappeared, people and other animals would go hungry and perish.
Thus, this may happen if resources were to become reduced or unavailable.

What methods do scientists use to monitor different sources of pollution and their environmental effects? How do they model runoff from land that creates water pollution? Your answer should include at least six complete sentences to explain the claim, evidence, and reasoning.
Answer:
Explanation:
Overview
NPS pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. NPS pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources. NPS pollution is caused by rainfall or snowmelt moving over and through the ground. As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.
Nonpoint source pollution can include:
Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas
Oil, grease and toxic chemicals from urban runoff and energy production
Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks
Salt from irrigation practices and acid drainage from abandoned mines
Bacteria and nutrients from livestock, pet wastes and faulty septic systems
Atmospheric deposition and hydromodification
States report that nonpoint source pollution is the leading remaining cause of water quality problems. The effects of nonpoint source pollutants on specific waters vary and may not always be fully assessed. However, we know that these pollutants have harmful effects on drinking water supplies, recreation, fisheries and wildlife.
There are several methods which are used to done environmental monitoring for different sources of pollution.
What is environmental monitoring?Environmental monitoring is a tool to assess environmental conditions and trends, support policy development and its implementation, and develop information for reporting to national policymakers, international forums and the public.
Air monitoringWater monitoring BiodiversityWaste monitoringRemote sensingEnterprise monitoringPollution control in environmental engineering, any of a variety of means employed to limit damage done to the environment by the discharge of harmful substances and energies.
Specific means of pollution control might include refuse disposal systems such as sanitary landfills, emission control systems for automobiles, sedimentation tanks in sewerage systems, the electrostatic precipitation of impurities from industrial gas, or the practice of recycling.For full treatment of major areas of pollution control, wastewater treatment, solid-waste management, and hazardous-waste management.

Create a hypothesis that can be tested in an experiment.
Remember, a hypothesis has a specific "if then" wording.It describes what will happen to the dependent variable when changes are made to the independent variable.For example, "If a plant is fertilized (independent variable), then it will grow faster (dependent variable)."
Design and plan an experiment.
Be sure to identify an independent variable, a dependent variable, and any controls.Remember, controls are factors which stay the same.In an experiment designed to test the previously stated hypothesis, one control would be to use the same kind of plant.Write a complete description of your experiment.Include a list of necessary materials.It is a good idea to follow a step-by-step procedure format.Think of everything you need to do, then write it down in the order it must be completed.Your description and procedure should be clear enough that another person could duplicate your experiment exactly.

How do auxins cause plants to bend?
A) Auxins make plant cells grow larger towards the light causing it to bend.
B) Auxins make plant cells grow heavier causing it to tip on one side.
C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

What is the function of junk DNA in cells?
Select all that apply.
a) protecting the ends of chromosomes
b) turning genes on and off
c) holding the nucleus together
d) coding for proteins
Answer:d
Explanation:
What best describes ribosomes?
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein
Explanation:
Are both strands of DNA copied continuously during replication? Explain your answer.
Answer:
Since the two strands of a DNA double helix are antiparallel, this 5′-to-3′ DNA synthesis can take place continuously on only one of the strands at a replication fork (the leading strand). On the lagging strand, short DNA fragments must be made by a “backstitching” process.

How does heart failure affect the lungs?
Carbon dioxide enters the lungs.
Blood leaves the lungs.
Fluid can build up in the lungs.
Too much oxygen enters the lungs.
Answer:
A damaged heart can't pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.

While savannas and temperate grasslands are both types of
grasslands and share many characteristics, they also have
some differences. Compare them below by writing each
characteristic in the correct location. You will use each only
once.
• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).
