The correct answer is The star must be very large.

The visibility of a star totally depends on its brightness and luminosity. The star can be easily seen because it is very large in size. The light emitted from the star is visible only because the size of the star is very large as compared to that of other stars present in sky. For example: if you compare a headlight of a car and flashlight of the mobile phone which are kept 10 feet away from the observer. The headlight of car is easily visible as compared to that of flashlight because is it bigger in size and hence its brightness and luminosity will be more as compared to that of flashlight.

natulia [17]
That prokaryote is <span>Psychrophile, a coccus and a decomposer.

1)The prokaryote is</span> shaped like a ball or generally has a round shape so it's called a coccus (Cocci in plural). This is one out of three terms, that are used to name bacteria. The other ones are bacillus and spiral. For example, Staphylococcus aureus is a bacteria that has a round shape but it's formed by more that one ball, that together look like a bunch of grapes.

2) This organism lives deep under the water, so it's named as a psychrophile or cryophile. This means they can live and reproduction at extremely low temperatures(-20ºC), and some places with those temperatures are the polar regions and the deep sea.

3) This prokaryote consumes dead organisms so it's classified as a decomposer.
Decomposers are organisms that can break down dead or decaying organisms. The process is an essential part of the nutrient cycle and is important for recycling the organic matter that occupies space in the biosphere.
