There is certain class of this type of meteorite that has been shown to contain structures that resemble fossilized bacteria and some larger structures of more complex nature, but the subject is still hotly debated and considered as unproven at best. These meteorites are very ancient and are thought to have been in existence during the creation of the solar system. They are made up of tiny grains that have fused together in space at high temperatures, so the likelyhood of them containing bacteria is very remote indeed.
Yes, bacteria contain proteins. Proteins are essential molecules that perform various functions within bacterial cells, such as structure, metabolism, and communication.
A pinch of soil can contain billions to trillions of bacteria, depending on factors like soil type, location, and environmental conditions. It is estimated that a gram of soil can contain anywhere from 100 million to 1 billion bacteria.
prokaryotic cells does not have nuclear membrane surrounded DNA, a characteristic of only bacterial cells.
Yes, bacteria can grow in distilled water if it is exposed to contaminants or nutrients that support their growth. Distilled water itself does not contain nutrients for bacteria to thrive, but if it comes into contact with substances that provide nutrients, bacteria can grow in it.
A small single-celled organism that does not contain nuclei is known as a prokaryote. Prokaryotes include bacteria and archaea, which are simpler in structure compared to eukaryotic cells that have a nucleus. These organisms have genetic material that is not enclosed within a membrane-bound nucleus.
Yes
A common type of meteorite that contains chondrules. Chondrites come from asteroids that did not melt when formed and are designated as H, L, LL, E, or C depending on chemical compositions. The H, L, and LL types are called ordinary chondrites. The L chondrites are composed of silicate minerals (mostly olivine and pyroxene, but feldspar as well), metallic nickel-iron, and iron sulfide (called troilite). Most L chondrites are severely shocked-damaged, probably by a large impact on the asteroid in which they formed. The C (or carbonaceous) chondrites are the most primitive meteorites. They contain water-bearing minerals and carbon compounds including a variety of organic molecules such as amino acids.For the source and more detailed information concerning your request, click on the related links section (Answers.com) indicated below.
They seem to be similar to C type asteroids or carbonaceous chondrites. That means they're made of rocky materials that never got hot enough to melt and differentiate. Phobos, at least, seems rather light for its size, indicating that it may contain a substantial proportion of ices as well.
Carbonaceous chondrites are a type of meteorite that contain a high percentage of carbon and other volatile compounds, along with silicate minerals and metal. They are among the oldest and most primitive materials in the solar system, believed to have formed around the same time as the planets. These meteorites are significant for understanding the early solar system's chemistry and the building blocks of life, as they often contain organic molecules and water-bearing minerals. Their diverse mineralogy and isotopic compositions provide insights into the processes that occurred during the formation of the solar system.
Very few ancient stromatolites contain fossilized microbes. While features of some stromatolites are suggestive of biological activity.
Uranium can be found in small quantities in some meteorites, especially those known as carbonaceous chondrites. These meteorites are valuable for studying the early solar system and can contain various radioactive elements, including uranium, which provides insights into the age and formation of the meteorite. Scientists use uranium isotopes in meteorites to date their formation and understand processes like nucleosynthesis in the early universe.

Bacteria doesn't contain salt.
The reason bacteria do not reproduce by mitosis is because bacteria do not contain chromosomes. There are numerous types of bacteria.
