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.
What else can I help you with?
Do bacteria contain proteins?
Yes, bacteria contain proteins. Proteins are essential molecules that perform various functions within bacterial cells, such as structure, metabolism, and communication.
How many bacteria are in a pinch of soil?
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.
What would contain prokaryotic cells Bacteria Fungi Plants Animals?
prokaryotic cells does not have nuclear membrane surrounded DNA, a characteristic of only bacterial cells.
Can bacteria grow in distilled water?
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.
What is a small single celled organisms that do not contain nuclei?
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.
Do Carbonaceous chondrites contain simple amino acids?
Yes
What are chondrites?
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.
What are the moons of mars made of?
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.
What are carbonaceous conderites?
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.
Biological term for layers of fossilised bacteria?
Very few ancient stromatolites contain fossilized microbes. While features of some stromatolites are suggestive of biological activity.
Uranium in meteorites?
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.
What are 3 main types of meteoroids?
stony - rocksmetallic - a nickel iron alloycarbonaceous chondrites - contain large amounts of organic chemicals
Does water exist on meteorites?
Yes, water can exist on meteorites, primarily in the form of hydroxyl (OH) and water ice. Some meteorites, particularly those from carbonaceous chondrites, have been found to contain significant amounts of water, which may have originated from the primordial solar system. Additionally, certain studies have detected molecular water within the mineral structures of these meteorites, suggesting that water was present during their formation.
Why is there salt in bacteria?
Bacteria doesn't contain salt.
Why don't cyanobacteria and bacteria reproduce by mitosis?
The reason bacteria do not reproduce by mitosis is because bacteria do not contain chromosomes. There are numerous types of bacteria.
Definition of a carbonaceous film fossil?
Carbonaceous film fossils are traces of plants or animals preserved as a thin film of carbon. All living organisms contain carbon. If they are compressed by layers of sediment fine details of the organism may be preserved. See http://facstaff.gpc.edu/~pgore/geology/historical_lab/preservationlab.php
Does mitochondria have bacteria in it?
Mitochondria are evolved from bacteria.They do not contain bacteria.
