What are the two types of limiting factors and how do they differ?
Answer:
Limiting factors fall into two broad categories: density-dependent factors and density-independent factors. ... Other density-independent factors include hurricanes, pollutants, and seasonal climate extremes. Density-dependent limiting factors tend to be biotic—having to do with living organisms.
Explanation:
answer up there. answer up there. answer up there. answer up thereThe two types of limiting factors are density-dependent factors and density-independent factors. These differ in their influence by the size of a population.
What are limiting factors?
A limiting factor is a variable of a system which causes a noticeable change in the output or another measure of a type of system. These are present in a limited amount.
Limiting factors are of two types: Density-dependent factors and density-independent factors. Density-dependent factors have varying impacts according to the size of the population. Density-dependent factors include food availability, predator density and disease risk. Density-independent factors are not influenced by a species population size. Density-independent factors include temperature, altitude, amount of sunlight, etc.

In Plants photosynthesis can only take place in the presence of sunlight during the day, respiration happens all day long, hence option c is correct.
What is respiration in plants?Plants' respiration is visible at night and day, plants consume oxygen during respiration while also releasing carbon dioxide. Both photosynthesis and respiration take place during the day.
However, only respiration takes place at night, which uses oxygen. A sequence of chemical processes known as cellular respiration converts glucose into ATP, which may then be utilized as energy for a variety of bodily functions.
Glycolysis, citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration.
Therefore photosynthesis takes place during the day but plants respire all the time, hence option c is correct.

Dandelions grow quickly and produce many seeds, ensuring that at least some plants will survive and produce seeds themselves. Which curve best represents the survivorship of dandelions?
Species strategies to survive and successfully reproduce define three basic survivorship curves. The survivorship curve type III is the one that best represents the Dandelion plants.
------------------------------
According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,
Type I.
Mortality often occurs at the end of the cycle, representing species with low mortality. Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough. These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.Type II.
The probabilities of dying are equals all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle. These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.Type III.
Significant mortality during the early stages of life. Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.These species produce large offspring at the same time, but they provide little or no parental care. The reproductive success of these species depends on the number of descendants and not on the parenting time spent.
According to this information, and the characteristics of the Dandelions, we might assume that this species is represented by type III curve.

How might an increase in the use of fertilizers affect the catfish carrying capacity
Explanation:
It might affect them by decreasing the carrying capacity, because an increase in food= larger fish=less carrying capacity
Answer:
When manure or commercial fertilizers enter surface water, the nutrients they release stimulate microorganism growth. The growth and reproduction of microorganisms reduce the dissolved oxygen content of the water body. Without sufficient dissolved oxygen in surface water, fish and other aquatic species suffocate.Hope this helps you !!Explanation:

Cross-sections of different areas of the same plant show cells with very different structures what does this tell you about the different areas.
A. The cells in the top image are a different color from the cells in the bottom image.
B. The cells in these 2 areas have different DNA.
C. The cells in these 2 areas have different functions.
D. The cells in the top image are similar than the cells in the bottom image.
Answer:
C. the cells in these 2 areas have different functions
Answer:
C. The cells in these two areas have different functions.
Explanation:
The plant tissues are classified into three major systems: vascular, epidermic, and root systems. The vascular system is formed by tissues referred to as xylem and phloem. The epidermis is composed of superficial tissues that cover plant organs (i.e., leaves, stem, roots, etc). Finally, the root system is formed by tissues whose function is to supply to other plant tissues and store nutrients. Moreover, the plant tissues are also classified into meristematic and permanent tissues. In this case, it is reasonable to suppose that structurally different plant cells that are located at different areas of the plant will have distinct functions.
Which statement explains what happens as magma rises inside a volcano?
Gases will contract in the chamber.
The pressure of the gas will disappear.
The magmatic pressure decreases.
Magma moves to other chambers.
Answer: the answer is C which is “the magmatic pressure decreases“
The magma rises and collects in chambers within the crust and as magma fills the chamber, pressure grows. If the pressure gets high enough the magma can break through the crust and spew out in a volcanic eruption., but If the pressure is low, do not break the crust. Thus the correct option is C.
What is molten magma?Magma is a molten and semi-molten rock mixture present under the surface of the Earth.
This mixture is usually made up of four parts such as a hot liquid base, called the melt, minerals crystallized by the melt, solid rocks incorporated into the melt from the surrounding confines, and dissolved gases.
