Which of the following is an example of parasitism? a. clownfish defending sea anemone from other predators b. hookworms consuming blood from inside an animal's intestine c. barnacles living harmlessly on the side of a whale while collecting food d. tree frogs using the trees to hide from predators

Its B as the hookworm does have a mutual relation with the host in this case the animal so it feeds on the animal with out the animal gaining any benifit and may harm the host
hope that helps

The correct answer would be b. hookworms consuming blood from inside an animal's intestine.

Parasitism is a type of biological interaction in which an organism (parasite) lives on or inside the body of the other organism (host).

Parasites can be of two types:

Ectoparasites: They live on the body of the organism, for example, lice, fleas, leeches et cetera. Endoparasites: They live inside the cell or inside the body of the organism, for example, Plasmodium, hookworm, tapeworm et cetera.

Parasites do not kill their host but they harm their host and withdraw nutrients from them.

Hookworms are bloodsucking endoparasites which live in the intestine of an animal.

Science27 of the most iconic, jaw-dropping photos of the earth and the moon from spacedave mosher  oct 1, 2018, 11: 13 am etnasa/flickrapollo 11 astronauts took this photo of earth on july 20, 1969.from the ground, earth looks like a boundless fertile plain that beckons to be explored and exploited.but astronauts would beg -  and even plead  - to differ."you realize that people often say, 'i hope to go to heaven when i die,'" jim lovell, an astronaut who flew on the apollo 8 and apollo 13 missions to the moon, previously  told business insider. "in reality, if you think about it, you go to heaven when you're born."lovell has seen first-hand that we live on a tiny rock hopelessly lost in the void. he's also quick to tell you it's the only one we've got - a  fragile spaceship  for more than 7 billion people: "you arrive on a planet that has the proper mass, has the gravity to contain water and an atmosphere, which are the very essentials for life. and you arrive on this planet that's orbiting a star just at the right distance - not too far to be too cold, or too close to be too hot - and just at the right distance to absorb that star's energy and then, with that energy, cause life to evolve here in the first place. in reality, you know, god has really given us a stage, just looking at where we were around the moon, a stage on which we perform. and how that play turns out is up to us, i guess."humanity has recorded photos of earth from hundreds, thousands, millions, and even billions of miles away, some of them taken by lovell himself.these images not only scientists study our dynamic world, but also understand how a habitable planet looks from afar, which aids the search for  more worlds. most importantly, however, the images underscore our peculiar existence on  a mote of cosmic dust.take a moment to ponder 27 of the most arresting images of earth that humankind has ever captured from space.a
