What is the life cycle of a parasite in stages ?<br> Please help me thank you
tresset_1 [31]

Answer:

Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Explanation: The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the broomrapes. There are six major parasitic strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism, trophically transmitted parasitism, vector-transmitted parasitism, parasitoidism, and micropredation.

How do cells maintain water balance through osmosis?
neonofarm [45]
Water then moves from cell to cell through the root cortex by osmosisalong a concentration gradient; this means that each cell is hypertonic to the one before it. In the centre of the root the water enters the xylem vessels. Water may move by diffusionthrough the cell walls and intercellular spaces.
