Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
Answer:
Xylem is different from phloem structurally and functionally
Explanation:
Xylem conducts water and minerals to the leaves where phloem transports the prepared food from leaves to different parts of plant body.
<span>microorganisms that are similar to bacteria in size and simplicity of structure but radically different in molecular organization. They are now believed to constitute an ancient intermediate group between the bacteria and eukaryotes.
</span>FULL ANSWER<span>Archaebacteria, or archaeans, are single-celled organisms. Although they were first classified with bacteria, they have since earned their own category. While they have a simple structure much like bacteria, there are many differences. They have a unique type of rRNA that sets them apart from their fellow prokaryotes. Furthermore, they do not cause sickness in people.Archaebacteria are considered extremophiles because they live in a variety of harsh environments and can tolerate extreme conditions such as, acidity and salinity. They are divided into three main groups: crenarchaeota, euryarchaeota and korarchaeota.Crenarchaeota consist of hyperthermophiles and thermoacidophiles that thrive in very hot, cold or acidic environments. Euryarchaeota consist of halophiels and methanogens that thrive in salty and oxygen-free environments. For example, euyarchaeota often live inside in the guts of animals. Compared to other the other groups of archaebacteria, less is known about korarchaeota. Scientists do konw that they are thermophilic and live in hot springs.</span>
