Carrying capacity is a constant that equals population size at the equilibrium point. The term that best describes the continued stability of the population is option B, carrying capacity.
---------------------------------
Populations that exhibit the logistic growth model depend on density.
Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate.
The population per capita growth rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that equals population size at the equilibrium point, in which the natality and the mortality rate get equal to each other.
Assuming that population size is N, when
N<K, the population can still grow. N approximates to K, the population´s growth speed decreases. N=K the population reaches equilibrium, N>K, the population must decrease in size because there are not enough resources to maintain that size.The sigmoid curve represents the logistic growth model.
The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent.
Dense-independent factors might be human impact or natural disasters (fires, volcanic eruption, flooding).
In the exposed example we have a small population of deer that could grow and increase in size because of the absence of its predator.
This deer population exhibited continuous growth until it reached a certain point in which it remained stable.
This point is the carrying capacity.
At this point N = K ⇒ the deer population stoped increasing its size because it reached the environmental maximal capacity.

Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
Explanation: is this good enough?
Answer:
Because its a sequence in which molecules can store their own energy and use it when needed such as in a chemical reaction , note that this is the main reason some molecules stay dormant during a chemical reaction and that is because they didn't use ATP
Explanation:
The principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ... AMP can then be recycled into ADP or ATP by forming new phosphoanhydride bonds to store energy once again. (This Is A Web Response) but feel free to use mine if it helps its a more simpler term.

why a genetic bottleneck can be an important evolutionary factor for a species
Answer:
Genetic drift decreases genetic diversity within a population.
Explanation:
Genetic drift decreases genetic diversity within a population. It is a change in allele frequencies due entirely to random chance and is more likely to affect smaller populations than large ones. Population bottlenecks can lead to genetic drift.

C. radioactivity
D. extinction
Answer:
A. greenhouse effect
Explanation:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. Climate change results from the shedding of gases like CO2 into the atmosphere where it can trap more heat.

Answer:
D. Design a device that can throw an object at least 15 meters.
Explanation:
First of all, the object shown as you may be able to tell, look like a catapult. It also shows the top end of it holding a ball, getting ready to launch it. It then shows a line of the ball traveling after being launched. The balls land of the ground at 15 meters. From this iformation you look at the options:
A. Design an object that is 10 meters tall.
No, because 10 meter is just the highest point of the ball being launched.
B. Design a vehicle that can travel across a 10-meter feild.
No, because it is the ball that is traveling, not the catapult.
C is about a vehicle traveling again, so eliminate that too.
D. Design a device that can throw an object at least 15 meters.
This describes exactly what we soo in the picture. Meaning D is correct.

Why are hydrogen bonding and popularity so important for water molecules?
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

Homeostasis is necessary for a cell to survive. What is the definition of homeostasis
Answer:
Homeostasis is the process of maintaining a constant internal environment suitable sustaining life.
Homeostasis continues to maintain ideal environment for enzyme action and all cell functions throughout the body.
Why homeostasis is necessary?It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
A series of control mechanisms at the organ, tissue, or cellular level maintain homeostasis.
Substrate supply, activation or inhibition of individual enzymes and receptors, enzyme synthesis and degradation, and compartmentalization are examples of control mechanisms.
The liver, pancreas, kidneys, and brain (hypothalamus, autonomic nervous system, and endocrine system) all contribute to homeostasis.
The liver is in charge of metabolizing toxic substances and maintaining carbohydrate metabolism with pancreatic signaling.
Thus, homeostasis is necessary for a cell to survive.

In terms of structure and function how do the vacuoles in a typical plant cell compare to those of a typical animal cell
Answer:
Vacuoles in animal cells do NOT help the cell take its shape, however, in plant cells, vacuoles are larger, and DO affect the shape of the cell.
The function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials.
What is the significance of the vacuole in plants and animals?Vacuoles are cell organelles found in both plants and animals, in plants, vacuoles are large, fluid-filled structures that occupy a large portion of the cell, and they perform several important functions, including storing water and helping to maintain the shape of the cell, while in animals, vacuoles are smaller and less in number than in plants, as they have a variety of functions, like storing waste materials, etc.
Hence, the function of the vacuole in plants is different from that in animals, as the vacuole in animals is smaller, while in plants it is larger and pushes the nucleus to one side while consisting of water and other materials
