Ecologists study both biotic and abiotic factors and how they interact. Therefore, ecologists often use methods and data from other areas of science, such as geology, geography, climatology, chemistry, and physics.
Abiotic factors refer to non-living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Examples of abiotic factors are water, air, soil, sunlight, and minerals

Through geology and geography, we can study biotic and abiotic factors within an ecosystem.
How can you study biotic and abiotic factors within an ecosystem?The interactions between biotic factors, such as organisms like flora and fauna, and abiotic factors.
For example, all animals (biotic factors) breathe in oxygen (abiotic factor). All plants (biotic factor) absorb carbon dioxide (abiotic factor) and need water (abiotic factor) to survive.
Thus, geology and geography, are the two ways to study biotic and abiotic factors within an ecosystem.

What causes stomach cramps?
Answer:
the main causes are, infection,abdominal growth,inflammation,obstruction blockages
Explanation:
“Stomach cramps” is a general term that refers to sharp, intermittent contractions or feelings of pain or discomfort that occur anywhere in the abdomen between the lower chest and the pelvis or groin. The abdomen consists of many organs, including the stomach, intestines, liver, gallbladder, pancreas, esophagus, and numerous blood vessels.
Stomach cramps are a common symptom of a wide variety of mild to serious diseases, disorders and conditions that are often related to the abdominal organs and sometimes the pelvic organs, such as the uterus and bladder. Most people will experience stomach cramps at some point during their lifetime, and they can occur in any age group or population. Common causes of stomach cramps include indigestion, gastroenteritis, menstrual cramps, bladder infection, and excessive flatulence (gas).
Stomach cramps may be generalized, which means they occur throughout the abdomen. Stomach cramps may also be localized in a small area of the belly, such as the lower abdomen or pelvis near the groin, or in the upper abdomen where the stomach is located.
Depending on the cause, stomach cramps can last for a few minutes or hours, such as when they occur from indigestion due to eating rich food or from vigorous exercise. Stomach cramps can also last for a few days, such as when they are due to a menstrual period. Long-term stomach cramping may be continuous or occur periodically and may be due to more serious conditions, such as colorectal cancer.
In some cases, stomach cramps may be caused by serious conditions, such as food poisoning or colorectal cancer. Seek prompt medical care if your stomach cramps are unexplained, persistent, or cause you concern.
Stomach cramps may accompany other symptoms, which vary depending on the underlying disease, disorder or condition. If you have other symptoms along with stomach cramps, be sure to inform your health care provider. This information will help your doctor diagnose the reason for your stomach cramps.

A student graphed distance versus time for an object that moves 14 m every 2 seconds. What is the slope of the ling on the graph. Please explain!
Answer:
A slope of 7, representing a speed 7 m/s.
Explanation:
Speed is defined as the distance traveled over time. Mathematically, it's calculated with the equation:
[tex]speed = \frac{distance}{time}[/tex]
Slope of a graph is the rate at which the y and x axis change together, the "rise over the run." Slope can be simply calculated using this equation:
[tex]slope = \frac{x_{2} - x_{1}}{y_{2} - y_{1}}[/tex]
Therefore, when graphing distance versus time, the change in distance is divided by the change in time to find the slope. This is the same as speed.
True or false Men can be carriers of X-linked disorders?
Answer:
True.
Explanation:
X-linked recessive diseases most often occur in males. Males have only one X chromosome.
HOPED THIS HELPED!!
Color-blindness results from both the expression of a single recessive sex-linked allele (b.)
Which of the following is a genotype of a colorblind male?
XbY
XBXB
XBY
XbXb
Answer:
XbY
Explanation:
because the question asks genotype of a male, the chromosomes would be XY, so XBX and XbXb can be eliminated leaving only XBY and XbY. XBY is incorrect because the question states that colorblindness is represented by lowercase b, so the correct answer is XbY.

The total wind power capacity in the united states in 2000 was about 2540MW. By 2015, the total wind power capacity in the United States was about 72,500MW Calculate percent change in the total wind power capacity in the United States from 2000 to 2015. Show the work
Answer:
2754.33% increase
Explanation:
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:
Percent change = [(total wind power capacity in 2015 - total wind power capacity in 2000) / total wind power capacity in 2000] * 100%
Percent change = [(72500 MW - 2540 MW) / 2540 MW] * 100%
Percent change = 2754.33% increase
Power is the amount of energy transferred or converted per unit of time. In the International System of Units, the unit of power is the watt, equal to one joule per second.
The total increase is 2754.33% increase
The total wind power capacity in the united states increased between 2000 and 2015. The percent change in the total wind power capacity in the United States from 2000 to 2015 is given by the formula:

Use of the GAH may increase the amount of hormones in the milk.
C.
Use of the GAH may provide extra milk to feed the poor.
D.
Use of the GAH may allow the farmer to reduce milk prices.
Answer:
B
Explanation:
A farmer uses genetic engineering to inject dairy cows with a genetically altered hormone (GAH) to result in the production of more milk, and the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.
What is a genetically altered hormone(GAH)?The GAHs that are used in dairy farming can result in an increase in the levels of hormones such as insulin-like growth factor 1 (IGF-1) in the milk, and these hormones can be harmful to human health and are also associated with an increased risk of certain cancers, such as breast cancer and In addition to concerns about the health effects of GAHs, there are also environmental concerns. The increased milk production resulting from GAH use can lead to overproduction, and animals get harmed by these genetically altered hormones.
Hence, the use of the GAH may increase the amount of hormones in the milk, which is a risk that is present in Option B.

How are Earth's structures created over time?
Answer:
Earth crust is constantly changing primarily due to plate tectonics (plate motion), but it also changes from activity on the surface from river, man made and meteorite impact. ... Continents and oceans do not ride atop the plates without changing. As the plates move and change so do the continents and oceans
Answer:
Explanation:
Earth's structures were created when the planet was first formed. Over time, its own gravitational and magnetic forces drove the Earth's core rotation. Other geological activities affected its structures; such as glacial movements, tectonic plates collisions and submersion, volcanic eruptions and so on. There were also major external events the asteroid impact that killed most lives on Earth. Human activities' impact on Earth's structures were relatively small until the recent centuries.
How are these atoms used to make new molecules and what types of molecules are made? Where does the energy come from to produce these new molecules?
Answer:
Atoms used energy to make new molecules.
Explanation:
Atoms used energy to make new molecules through making bonds with one another because bonds allow atoms to attached tightly with each other. The energy come from the external environment in order to produce new molecules. So we can conclude that energy is the main ingredient needed for making new molecules and this energy is gained from the environment.
