Answer:
They formed from a cloud of dust and gas.
Explanation:
A nebula is where the formation of stars takes place, so the Nebula Theory would pertain to the planets forming in the same way.
Answer:
-A solution is a mixture in which one substance is dissolved in another. When elements and compounds that are dissolved in water leave a solution, crystallization occurs.

For the answer to the question above,
<span>The only taxon in which the biological characteristics are clearly identifiable is the <em><u>"species".</u></em></span>
The doctor or nurse will ask a urine sample of the daughter for lab analysis to check for bacteria, red blood cells or white blood cells. Sometimes after the urine lab analysis it will be followed by a urine culture. This test will tell the doctor what kinds of bacteria are the source of the infection and which treatment or medicine will work the most. If the daughter is having frequent infections or low grade fever that the doctor concludes that it may have been caused by an abnormality in the urinary tract, she may have a magnetic resonance imaging (MRI), a computerized tomography (CT) scan or ultrasound. The doctor or nurse may use a contrast dye as well to highlight structures in the child’s urinary tract. Moreover, the doctor may conduct a cystoscopy, using a long, thin tube with a lens (cystoscope) to see inside the child’s bladder and urethra if the child will have recurrent UTIs.
Answer:
They have genetic material.
Explanation:
All three domains and viruses have genetic material. They have to, otherwise they couldn't reproduce, whether sexual or asexual. In viruses, it can be RNA or DNA; obviously in eukarya it tends to be DNA, remembering that humans are eukaryotes; and in the other two domains a similar pattern is followed.
Why not the other options?
They are composed of cells
- Viruses technically don't have "cells," and even to say cells plural can be a misnomer for some of the more simple forms of life that are unicellular.
They are living things.
- All three domains are alive (bacteria, archaea, eukarya) but viruses are technically not considered to be alive.
They have organelles.
- Eukarya and prokarya technically both have organelles (think of prokaryotic ribosomes), but not all groups that you mentioned have organelles. Remember that organelles ("little organs") are specific groups of cells performing a function, and they usually have names.
