What is carrying capacity in ecology?
In ecology, carrying capacity is measured as the maximum load of an environment. The physical features present in the environment act as limiting factors (e.g. food, water, competition, etc.). Thus, the population limit can be expected to depend on these factors.
What is carrying capacity of an ecosystem?
Populations grow at a rate limited by the availability of the Earth’s resources. A population may grow at a faster rate and follow a J-shaped curve. When the birth rate surpasses the death rate of the species, this results in exponential growth.

Write a summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.
Consider the motion of the balloon and its air contents in terms of momentum. In step 1 above, the total momentum of the balloon and its contents was zero. Recall that momentum = mv. Both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero.
Now think about what happened when the air escaped from the balloon. A certain mass of air accelerated in one direction. In order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. Use this scenario to help you explain why the soda can rotates when the water squirts out of the escape holes.
What was your hypothesis concerning the water-filled can? According to your data, do you think your hypothesis was correct? (Be sure to refer to your data when answering this question.)
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Give at least one more example of Newton's third law in everyday life.
Answer:
Consider the motion of the balloon and its air contents in terms of momentum. In order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. Use this scenario to help explain why the soda can rotates when the water squirts out of the escape holes. Give at least one more example of Newton's third law in everyday life to show how it applies to your life.
Explanation:
The motion of the balloon and its air contents in terms of momentum, balloon's motion, and even the air within. The mass-containing balloon itself would move in a reverse way in order to maintain the system's total momentum at zero, which can be explained by Newton's third law.
What is Newton's Third Law?According to Newton's third law, whenever two bodies come into contact, they exert forces on each other that really were equal in size and directed in the reverse direction.
What is motion?An object changing its location with regard to space as well as time is referred to as being in motion.

Describe the steps of the rock cycle and relate them to weathering, erosion, plate tectonics, and mountain building
Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Explanation:
The Rock cycle is the geological concept, in which transitions between sedimentary, metamorphic, and igneous rocks over geologic time occurs. The transitions between rocks occur due to weathering, metamorphism, erosion, and sedimentation.
The steps involved in the rock cycle are:
Weathering refers to the breakdown or dissolving of the rocks on the Earth's surface. After the weathering, the process of erosion occurs in which rock particles and minerals are transported via plants, animals, wind, and water. The igneous rocks are formed by plate tectonics. The heat from the mantle fuels the plate tectonics, which converts the igneous and sedimentary rocks into metamorphic rocks. Mountain building is caused by the intense deformation of layered rocks and the activity of metamorphic and igneous rocks in the orogenic stage.
Thus, the rock cycle is involved in various processes and transitions among different types of rocks that occur in the rock cycle.

A student wishes to measure the speed of a toy car at the bottom of an inclined plane. Which information is needed to calculate speed?
a) the mass of the car and the height of the inclined plane b) the friction of the surface of the inclined plane and the mass of the car c) the length of the inclined plane and the time for the car to descend the inclined planed) the length of the car and the time for the car to descend the inclined plane
Helpppppppppp!!!!!
Answer:
c) the length of the inclined plane and the time for the car to descend the inclined plane.
Explanation:
The information that is needed to calculate speed is the length of the inclined plane and the time for the car to descend the inclined plane. Thus, the correct option for this question is C.
How speed is defined?Speed is defined as the rate of change of position of an object in any direction. It is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
If you want to calculate the speed of the car, you must definitely be required to determine the length of the inclined plane through which it is running along with the time for the car to descend the inclined plane. There are some necessary quantities that are required prior to determining the actual values in the same or different contexts.
Therefore, the correct option for this question is C.

Explain the relationship between the variation in estradiol and progesterone rates in the female body and the events that occur in the uterus during the menstrual cycle
Answer:
The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces progesterone. During most of this phase, the estrogen level is high. Progesterone and estrogen cause the lining of the uterus to thicken more, to prepare for possible fertilization.
Progesterone and estrogen are necessary to prepare the uterus for menstruation, and their release is triggered by the hypothalamus. Once you reach puberty, the ovaries release a single egg each month (the ovaries typically alternate releasing an egg)—this is called ovulation.
Explanation:
The answer is an explaination itself.

Plants and trees absorb carbon dioxide from the atmosphere and convert it to sugars through photosynthesis as they grow. Furthermore, by planting more trees, more carbon will be extracted from the atmosphere and deposited for a long time.
