Limiting factors and carrying capacity are connected to the number of organisms in an ecosystem.
Limiting Factor
A limiting factor is any part of an environment that controls a population within one area. For example, available food is a limiting factor. There is not unlimited food, so it limits how many organisms can survive in one area. Organisms can only survive if there is enough food for them. Space is also a limiting factor because there is only so much space for the population. Overall, any factor that forces the organisms to compete or that limits resources is a limiting factor.
Carrying Capacity
The carrying capacity of an area is the total number of organisms that an ecosystem can safely support. For example, one ecosystem might have a carrying capacity of 5,000 bunnies. This means that the ecosystem cannot sustain more than 5,000 bunnies. When a population begins to near the carrying capacity, birth rate will decrease or death rate will increase. Since resources start to dwindle as carrying capacity is reached, it becomes more difficult for the population to grow.
The limiting factors of an ecosystem create the carrying capacity. For instance, if there is only enough food to feed 5,000 bunnies, then the carrying capacity will be 5,000.

take a position on the existence of a priori knowledge referencing relevant rationalist and empiricist philosophers.
A sort of epistemic justification known as a priori justification is in some ways independent of experience.
What does philosophy mean by a priori knowledge?Since Immanuel Kant, a posteriori knowledge—which is obtained through experience—has been contrasted with a priori knowledge, which is information that is learned independently of any particular experience.
Do rationalists think that knowledge is known beforehand?In the area of epistemology, or the theory of knowledge, where its claims are most clear, rationalism maintains that at least some human knowledge is acquired through a priori (prior to experience), or rational, insight as opposed to sense experience, which all too frequently offers a confused and merely tentative approach.

starvation would cause which of the following acid-base conditions? also, determine what type of compensation (metabolic or respiratory) there would be
Option c is the appropriate response. With respiratory compensation, acid-base conditions caused by starvation would result in metabolic acidosis.
Respiration and metabolism are interdependent. Metabolic compensation and respiratory acidosis or alkalosis go hand in hand. Similar to metabolic alkalosis, respiratory compensation is related to metabolic acidosis. Within cells, a process known as cellular respiration uses enzymatic pathways (such as glycolysis and the Krebs cycle) to break down glucose, releasing water, carbon dioxide, and ATP in the process. Direct responses to metabolic demands are made through respiration. The lungs carry out a number of metabolic processes, such as gas exchange, the inactivation of vasoactive chemicals, the conversion of angiotensin I to angiotensin II by the angiotensin-converting enzyme (ACE), and protein synthesis.
Therefore, we can conclude that Option C is the proper response. Acid-base conditions brought on by hunger would lead to metabolic acidosis with respiratory correction.

In animal cells, the plasma membrane's external side comes into touch with the extracellular space. While bacteria's cell wall is formed of peptidoglycan, plants' cell walls are composed of cellulose.
What are the differences in the cell borders between animal and plant cells?Animal cells are eukaryotic cells with a nucleus that is membrane-bound. In a number of crucial ways, they vary from plant cells. These cells are devoid of plastids, a cell wall, and other cellular organelles.
Bacteria lack a nucleus and organelles that are attached to membranes because they are prokaryotic. A nucleus and membrane-bound organelles like the mitochondria or golgi apparatus are present in eukaryotic cells, which are what make up plants and animals.

4. A car of mass 800 kg accelerates from 5m / s to 25m / s in 10 s. a) Calculate the acceleration. b) Calculate the resultant force exerted.
Answer: To calculate the acceleration of the car, we can use the equation:
acceleration = (final velocity - initial velocity) / time
Plugging in the values given in the question, we get:
acceleration = (25 m/s - 5 m/s) / 10 s = 2 m/s^2
To calculate the resultant force exerted on the car, we can use the equation:
resultant force = mass * acceleration
Plugging in the values given in the question, we get:
resultant force = 800 kg * 2 m/s^2 = 1600 N
This is the force that must be exerted on the car to accelerate it from 5 m/s to 25 m/s in 10 s.
A) As, the accelerarion equation is V - U/t
so its 25-5/10 so its 2m/s^2
B) With the above answer in A) we can calculate the force with the equation f = m * a
so , 800*2 = 1600N

What is an approximate interval?If you know the exact distribution of the test statistic, and use that distribution's quantiles to make confidence intervals, that interval is exact. If you approximate the distribution of the test statistic, then the interval is approximate.The Empirical rule states that for a normal distribution, nearly all of the data will fall within three standard deviations of the mean . The empirical rule is further illustrated belowThe Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
68% of data falls within the first standard deviation from the mean.95% fall within two standard deviations.99.7% fall within three standard deviations.From the information given, the mean is $150 and the standard deviation is $20.2 standard deviations = 2 × 20 = 40
