how does a tape worm feed
Answer:
The tapeworm feeds off the food that the host is digesting.
Explanation:
Tapeworms get into the body when a person eats or drinks something that's infected with a worm or its eggs. Once inside the body, the tapeworm head attaches to the inner wall of the intestines.
Answer:
Tapeworms do not have a digestive tract. Instead, they absorb their nutrients from the gut contents of the host directly through their outside surface, tegument. New proglottids are constantly formed in the neck of the worm and along the length of the tapeworm they mature.

Which of the following is not a role of ATP synthase?
ATP synthase assists in the formation of ATP from ADP and a free phosphate group.
ATP synthase acts as a channel protein.
ATP synthase donates an electron to the electron transport chain.
ATP synthase facilitates the movement of hydrogen ions from inside the mitochondrial membrane to the outside of the membrane.
Answer:
ATP synthase donates an electron to the electron transport chain.
Explanation:
ATP synthase donates an electron to the electron transport chain.
What is ATP synthase ?Adenosine triphosphate (ATP) is produced by the enzyme ATP synthase during the process of cellular respiration. The primary source of energy used by cells is ATP.
Adenosine diphosphate (ADP) and an inorganic phosphate (Pi) are used by ATP synthase in the process of oxidative phosphorylation, which is the mechanism by which enzymes oxidize substrates to produce ATP. All life forms contain ATP synthase, which is responsible for all cellular functions.
Producing ATP is the purpose of ATP synthase. All cellular functions are powered by ATP, which is constantly used by cells and required for production.
Therefore, ATP synthase donates an electron to the electron transport chain.

What is one way that asteroids and comets are different?
Astronomy.
Answer:
what they are made of
Answer:
While asteroids consist of metals and rocky material, comets are made up of ice, dust, rocky materials and organic compounds. When comets get closer to the Sun, they lose material with each orbit because some of their ice melts and vaporizes. Asteroids typically remain solid, even when near the Sun

Explanation:
There are more than 3,000 species of snakes on the planet and they’re found everywhere except in Antarctica, Iceland, Ireland, Greenland, and New Zealand. About 600 species are venomous, and only about 200—seven percent—are able to kill or significantly wound a human. Snake vision varies greatly between species. Some have keen eyesight and others are only able to distinguish light from dark, but the important trend is that a snake's visual perception is adequate enough to track movements. A young snake that is still growing may shed its skin up to four times a year, but an older snake may shed only once or twice a year.Snake venoms are complex mixtures of proteins, and are stored in venom glands at the back of the head.[

A) a nest of robin eggs is abandoned
B) a single robin dies
C) a population of robins compete for food
D) a population of robins die
Answer:
It should be D.
Explanation:
The food chain will be unbalanced if a whole population of robins die. I hope this helps! If this answer is wrong then I would love to recieve some feedback on what I did wrong! Thank you!
If population of robins die, the food chain will be unbalanced and this makes a large impact on the environment.
What is food chain?A food chain refers to the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism. The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain.
Moreover, it is a linear network of links in a food web starting from producer organisms and ending at an apex predator species, detritivores, or decomposer species. A food chain also shows how organisms are related to each other by the food they eat. Each level of a food chain represents a different trophic level.
Hence, imbalance of food chain results in the extinction of robins from the environment.
