Which of the following describes a relationship of predator-prey

oxpecker birds eat parasitic ticks off the backs of zebras

a tapeworm latches itself in the intestines of a rat, feeding off all the nutrients eaten by the rat

a polar bear catches a seal for dinner

birds feed off the insects that are stirred up from the grasses as cattle move through

The correct answer would be A polar bear catches a seal for dinner.

Predator-prey is an ecological relationship between organisms in which one organism kills or hunts the other organism and eats it for nutrition.

The organism which kills the other organism is termed as predator and the organism which gets killed is termed as prey.

For example, tiger and deer follow the predator-prey relationship in which the tiger is the predator and deer is the prey.

Similarly, polar bears are the predators of the seal as they hunt and eat the seals.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

the index of refraction of the second medium is higher. i just took the test trust me !
