population sizes of three African animals in 1990 and in 2000.
Lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetah.
Limiting factors are those factors in the ecosystem which can limit the growth of population of a species in an ecosystem. Predation and competition are two limiting factors in the ecosystem that can decrease or extinct the population of a species. Predation is a limiting factor in which predatory organisms are dependent upon a prey organisms. This is natures way of limiting the surplus growth of prey population and to maintain a balance in ecological community. Competition is a limiting factor in which one or more same or different type of organisms compete for the same resource in an ecosystem. The one which is more competitive will derive those resources other than the one which is less competitive.
According to the given data, it is evident that the population decline in predator cheetah and lion populations because of decline in zebra population but the decline in cheetah population is more than that of lion. It explains the fact that lion is more competitive than cheetah in deriving the food which is already limited. Therefore, lion outcompete cheetah.

Why does PE = mgh equal PE = Fw h ?
Answer:
Why is potential energy MGH?
Potential energy is energy an object has because of its position relative to some other object. ... For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.
Explanation:
Yes Yes Yes Yes Yes Yes
Observe: Click Reset. Move the Initial cell volume slider back and forth. How does the initial cell volume affect the solute concentrations inside and outside the cell?
True or False. More force is needed to move an object if you move the fulcrum closer to the load?
1. False
2. True
Answer:
false
Explanation:
if the fulcrum is closer to the load, it is esier and requires less force.
Answer:false
Explanation:A lever is a simple machine that is used to lift or move heavy loads by use of relatively smaller forces. It uses a fixed support or hinge known as a fulcrum.

Diabetes is often suspected when glucose shows up in urine tests. Use the model to explain how glucose could be present in urine. Why do you think this symptom is especially concerning for young people?
Answer:
S.A for Edmentum and Plato
Like and Rate
In step 1, blood goes to the kidney for filtration. If excess sugar exists in the blood, the filtered substances will have more sugar than they do in a person who doesn’t have diabetes. In step 2, there is some reabsorption of sugar. But if there’s an unusually high amount to filter, some sugar will stay in the urine as it passes through the renal tubule to be excreted by the body. This symptom is concerning because it could stress the kidney, which could lead to kidney problems at a young age.

Based on the video, do you think changes to the environment could still affect living things on Earth today? Explain your answer using information from the video to support your argument.
Answer:
I didn't see the video but global warming might be one.
Explanation:
Due to global warming the polar ice caps are melting, so that means a decrease in the food a polar bear might have.
Answer:
An ice age caused Earth’s oceans to cool, which killed many of the unicellular organisms. When the ice age ended and Earth warmed, the continents broke apart. This event allowed the shallow seas to cover the continents. The warming of Earth, accompanied by the seas covering the land, created the proper conditions for multicellular organisms to form.

If distance=rate x time, which of the following must also be true?
A- rate= distance x time
B- time= distance/rate
C- distance= rate/time
D- time= rate/distance
If distance = rate x time
then,
Time = Distance/Rate
Hence, Option B is correct.
Time is directly proportional to distance.
What is meant by Rate?The ratio of two related numbers expressed in several units is known as a rate in mathematics. If one of these numbers is used as the ratio's denominator and it is assumed that this quantity may be modified in a predictable way (i.e., is an independent variable), then the numerator of the ratio represents the rate of change in the other (dependent) variable.Speed, heart rate, and flux are examples of common rates that are expressed as "per unit of time." Exchange rates, literacy rates, and electric field are a few ratios that don't need time as the denominator (in volts per meter).A rate that is defined using two numbers of the same units will provide a dimensionless quantity that can be stated as a percentage, fraction, or multiple. Examples of these rates include tax rates and literacy rates.To learn more about Rate, refer to:
