It's chemoautotrophs because cyanobacteria can be mixotrophic if needed and they are classified as algae.

Chemoautotrophs make their own food by extracting compounds from the ocean.

Chemoautotrophs are organisms that obtain their own food (energy) from inorganic chemical compounds such as sulfur, ferrous iron, hydrogen sulfide and ammonium in their environment. These occur by chemosynthesis in which the organisms use chemical energy to produce carbohydrates. Chemoautotrophs are usually found in hostile environments such as at the bottom of the ocean or in acidic hot springs. Examples of chemoautotrophs include; thermoacidophiles, methanogens, nitrifiers and halophiles.

The large population of microbes that contributes to the gut microbiota and have an important role in food processing are called <u>Commensal microorganisms</u> .

The human body is host to trillions of microbes or bacteria. Most of these are useful but may become harmful when out of control.

The microbiota consists of a wide variety of bacteria, viruses, fungi ,and other microorganisms present in a singular environment such as the human digestive tract.

<h3>Gut microbiota : </h3>

The gut microbiota is vast and complex collection of microorganisms that profoundly affects human health gut microbiota are present in the digestive tract of vertebrates including humans.

The function of gut microbiota in body function includes harvesting energy from digested food, protecting against pathogens, regulating immune system and strengthening biochemical barriers of the gut and intestine changes in microbiota composition can affects these functions.

The normal gut microbiota have specific functions like host nutrition metabolism, maintenance of structural integrity of the gut mucosal barrier, helps in immunity, protect against pathogens.

<h3>Commensal microorganisms:</h3>

Commensal microorganisms are those type of microbes that reside on either surface of the body or at mucosa without harming human health . commensal bacteria are 10 times more than the cells present in our body.

Example - Streptococcus oralis and Streptococcus salivarius .

Commensal microorganisms plays an important role against pathogens including respiratory pathogens. It acts on the host's immune system to induce protective response that prevents colonization an invasion by pathogens. On the other hand these bacteria can directly inhibits the growth of respiratory pathogens by producing antimicrobial products .it also competing for nutrients and adhesion sites. Provides the host with essential nutrients.

<h3>What are microbes ?</h3>

Microbes are tiny living things that are found all around us and are too small to be seen by eye. They live in soil, water and in air. The human body is the home of trillions of microbes.

The lac operon in E.coli regulates genes that code for enzymes required for breakdown of lactose. The lac operon is____ operon t

user100 [1]

Ans.

Lac (lactose) operon in a type of bacterial operon, which shows a cluster of genes that are regulated by a single promoter. It is composed of an operator, promoter, a terminator, and three structural genes (lacA, lacY, and lacZ), which are responsible for the transport and breakdown of lactose.

The lac operon is an inducible operon as it gets activated in the presence of lactose and expressed its functional genes in the form of proteins (or enzymes) for lactose metabolism.

Thus, the correct answer to be fill in first blank is 'inducible' and in second blank is 'lactose.'

Viktor [21]

Answer:

cAMP dependent pathway is important for processing of life.

Explanation:

cAMP pathway is also called as adenynyl cyclase pathway.

This mechanism requires different steps like-

G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
The Gα stimulate G protein complex to exchange GDP for GTP and then the complex is released.
Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.
