What is the role of epinephrine in cell signaling?

Prokaryotic nature (does not have a membrane-bound nucleus) is the main characteristic used in classifying kingdom monera into archaea and bacteria.

Kingdom monera is classified into three sub-kingdoms - Archaebacteria, eubacteria, and cyanobacteria.

They contain 70S ribosomes DNA and is not bound by a nuclear membrane. It lacks organelles like mitochondria, lysosomes, plastids, Golgi bodies, endoplasmic reticulum, and centrosome. They reproduce by binary fission or budding. Lives in anaerobic or aerobic conditions.

They are generally unicellular. These are environmental decomposers and mineralizers. They have different modes of nutrition - autotrophic (photoautotrophs or chemoautotrophs), heterotropic, parasitic, saprophytic, and symbiotic.

Examples of monera include: blue-green algae (Cyanobacteria), cocci-shaped bacteria- Streptococcus, bacillus-shaped bacteria- E-coli, vibrio-shaped- vibrio cholera, spiral-shaped bacteria- Trepanoma palladium.

Hence scientists divide monera into 3 sub kingdoms based on the mode of nutrition, cellular organization, etc.

Even if the mitogen is removed, it will still trigger the cell in the G0 phase to enter the G1 phase. The division process is gonna get faster in the call in the G1 phase.

Mitogen is a small bioactive protein that triggers the cells to start dividing i.e., start the process of mitogenesis. The G0 phase is when the cells are in a state of rest. It does perform its functions but does that without actively dividing. In the G1 phase, the cells accumulate enough protein in order to undergo mitosis in the near future.

The first RNA molecule capable of self-replication, according to the RNA universe hypothesis, is what gave rise to life on Earth.

In the 1960s, Leslie Orgel, Francis Crick, and Carl Woese proposed the RNA World Hypothesis. It suggests that ancient living forms may have stored their genetic information exclusively in RNA.

The phrase "RNA World" was originally used in an article written by Harvard molecular scientist Walter Gilbert in 1986. Because RNA was a rather unstable molecule, the concept proposes that DNA eventually evolved into the genetic material as a result of evolution. The RNA World Hypothesis states that RNA was the main form of life approximately 4 billion years ago. This is partly because RNA can act as both genes and enzymes.

Heterotrophs must obtain their energy from other living things, whereas autotrophs can harness the sun's energy.

Organisms can be categorized into two main groups: autotrophs and heterotrophs, based on how they receive energy and nutrients. Because they can manufacture their own food from raw materials and energy, autotrophs are referred to as producers. Numerous varieties of bacteria, plants, and algae are examples.

When an organism uses other plants or animals for food and energy, it is referred to as a heterotroph. Heterotrophs are a group of organisms that are found in the second and third tiers of a food chain, and their name derives from the Greek terms hetero, which means "other," and troponin. Each food chain is composed of three trophic levels, which describe an organism's role in an ecosystem. Autotrophs, which include plants and algae, make up the first trophic level of the food chain. Herbivores—animals that eat plants—dwell on the second level. Omnivores and carnivores (animals that eat meat) live on the third level (animals that consume both plants and meat).

Lysogenic bacteriophages contribute to bacterial virulence because bacteriophages can carry and transfer virulence genes to the bacterial host. When a bacteriophage infects a bacterium and integrates its genetic material into the bacterial chromosome, the resulting lysogen (bacterium with integrated phage DNA) can carry additional genes that encode virulence factors.

Virulence factors are molecules or proteins that enhance the ability of a bacterium to cause disease in a host organism. These factors might include toxins, adhesion proteins, immune evasion molecules, or other elements that help the bacterium establish infection and evade the host's immune responses.

When a lysogenic bacteriophage carries virulence genes, it effectively turns a harmless or less virulent bacterium into a more pathogenic one. This phenomenon has been observed in several bacterial pathogens, such as the bacterium Vibrio cholerae, which causes cholera. In these cases, the presence of lysogenic phages can significantly increase the severity of the disease caused by the bacteria.

Plasma is the clear, straw-colored liquid portion of blood that constitutes 55% of total blood. Along with water, salt, and enzymes also contains important components like antibodies, clotting factors, and the proteins albumin and fibrinogen.

Plasma is formed from water and salts absorbed through the digestive tract. It is necessary to help our body recover from injury, distribute nutrients, remove waste and prevent infection, while moving through our circulatory system.

Plasma proteins are grouped into 3 fractions:

Plasma is the intravascular part of extracellular fluid that contains mostly water (up to 95% volume), and contains dissolved proteins (6-8%).
