<h2>Answer:</h2>

The substances which cannot be separated are called elements.

<h2>Explanation:</h2>

An element is a type of particle having a similar number of protons in their nuclear cores. For instance, the nuclear number of oxygen is 8, so the component oxygen comprises all iotas which have 8 protons.  

One hundred eighteen elements have been recognized: the initial 94 happen normally on Earth, and the rest 24 are manufactured ones. There are 80 components that have at any rate one stable isotope and 38 that have solely radionuclide, which rot after some time into different components.

What major organelle are prokaryotes missing that eukaryotes have?
djyliett [7]

Answer:

Nucleus

Explanation:

Prokaryotes are the organism that came earlier than eukaryotes on this earth. These prokaryotes do not have a nucleus and other membrane-bound organelles like chloroplast, mitochondria, Golgi apparatus, endoplasmic reticulum, etc.  

So as prokaryotes lack membrane-bound organelle their genetic material is not enclosed in the nucleus therefore their genetic material remains in the cytoplasm of the cell while eukaryotes have membrane-bound nucleus in which their genetic material are present.  

So the nucleus is the major organelle that prokaryotes are missing that eukaryotes have.

Lisa had 20 grams of water. She poured out 15 grams. Which of the following physical properties of the water changes? (4 points)
Black_prince [1.1K]

Answer:

Volume

Explanation:

The boiling point and density of water never changes, no matter how much you add

So the answer CAN'T be Boiling point or Density

Electrical Conductivity changes <em>only when the number of ions in a solution changes</em>

So it CAN'T be Electrical Conductivity

It has to be VOLUME because volume is the only physical property that changes when you add or take away liquid from a liquidous mixture
