Answer:

What are centrioles and centrosome?

Within the cell, a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM. They also enable movement of other organelles within the cytoplasm

Explanation:

Answer:

a centrosome is a structure that organizes microtubules during cell division. Each centrosome contains “paired barrel-shaped organelles” called centrioles and a “cloud” of proteins referred to as the pericentriolar material, or PCM.

Centrioles are made up of short lengths of microtubules “arranged around a central cavity.” Each centriole is around 500 nm long and 200 nm in diameter. The function of centrioles in animal cells is to organize the PCM to aid in microtubule formation.

Answers

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable

Pluto's surface is made mostly of frozen nitrogen..Pluto's orbit is slowing down due to tidal friction.What is Falsifiable and Non-falsifiable hypotheses?

Falsifiability is the capability for some proposition, statement, theory or hypothesis to be confirmed wrong. That capacity exists as an important component of the scientific approach and hypothesis testing. In a scientific context, falsifiability exists sometimes regarded synonymous with testability.

The falsifiable hypothesis can be denied by tests done with the most delinquent technology. The non-falsifiable hypotheses on the other hand can't refuted as tests have confirmed them to be true.

Hence,

The hypotheses about the dwarf planet Pluto can be divided into the following:

Non-falsifiable

Pluto has an unpleasant climate.Pluto's landscape is dull and boring compared to other dwarf planets in its vicinity.  

Falsifiable

Pluto's surface is made mostly of frozen nitrogen..Pluto's orbit is slowing down due to tidal friction.
