This is a symbiotic relationship between the Boxer crab and sea anemone.
The symbiosis is a type of relationship between two species which has benifit for both the participating organisms.
Here in case of boxer crab, the crab gets the help from the sea anemone in the form of protection. The sea anemone chases the predators and thereby saves the organism from being hunted.
On the other hand, the sea anemone gets food from the crab's prey which he hunts.
So there's a benifit for both.
The given statement-Logistic growth curves are density-dependent is True.
Logistic growth curves describe population growth that takes into account density-dependent factors, such as competition for resources and predation.
The logistic growth model assumes that as a population grows, it will eventually reach a point where resources become limited, and the growth rate slows down.
This is known as the carrying capacity of the environment, which is the maximum population size that can be supported by the available resources. Thus, the growth rate of the population becomes dependent on the population size or density. Hence, the statement is True.

The correct answer is true.
The density dependent factors are those factors, which is affect the size of the population.
The logistic growth curve shows a a lag phase, a log phase and a stationary phase. In the lag phase, the growth of the organism is minimal, here it prepare for the growth, in log phase, the population growth is exponential. As the resources in a particular area is limited and carrying capacity is also limited, after a certain population density, the growth become stationary, which means mortality becomes equal to the birth rate. As the logistic curve is affected by the density of the population, it would be density dependent.
P.S.- if the resources are not limited, the population continuous to grow exponentially, and would represent exponential growth curve.
Answer:
The correct answer would be B. semi-permeable.
Plasma membrane of any cell including red blood cell is semi-permeable in nature as it is made up of lipid bilayer.
It permits the passage of certain substances across the membrane while it blocks other substances.
Gases, small uncharged or non-polar substances such as oxygen, carbon dioxide, et cetera can easily pass through the cell membrane of a cell.
Large or charged molecules such as proteins, sodium ions, potassium ions et cetera can not pass through the cell membrane. They require carrier proteins to pass through the membrane.
