Answer:

c. the cost to growth of allocating resources to defense

d. consistent fitness benefits of high allocations to defense

Explanation:

In order to ensure survival by  escape of  grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .

The basic idea of the hypothesis is that the type   of  defence that an organism e.g plant  will adopt  against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.

pantera1 [17]
In the development of a cancer cell, the formation of new blood vessels is called Angiogenesis, option B. When tumors are present in the body, circulation and the distribution of nutrients in the body is altered; thus, resulting in different kinds of disorders associated with cancer. With the presence of cancer, these tumors need more nutrients to spread and grow, which results in the formation of more blood vessels.

Which cell is most important for the defense against parasitic organisms ?
Murljashka [212]

I'd say, ina general way, that the most imporant cells in defense against parasitic organisms are definitely white blood cels, the cells responsible for defeating antigens, pathogens and deseases.

Although these might be the most important ones in that specific task (defending against parasitic organisms), all the cells in the immune system, along with other non-cell things are important, since they all play a specific role indispensable in our immune system.


Hope it helped,
