A, B, C, D and E are pathogens of different diseases for human beings. The route of entry of pathogens in human body is differen

Goryan [66]

Answer:

Microorganisms which causes diseases is known as pathogen.

Explanation:

PATHOGEN -: Pathogens are agents that live in a host and are responsible for causing infections or diseases in that host, such as a human being. Microorganisms such as bacteria , viruses , fungi or protozoa, or other organisms such as parasites, worms and even contagious proteins such as prions, may be pathogens.

Viruses: Viruses are micro-organisms that are composed of nucleic acid and covered by a protein sheet. A lipid (fatty) outer layer is also present in some viruses. Enveloped viruses are called these. Non-enveloped viruses are considered those that do not have this lipid outer layer. Only inside their host's living cells are viruses able to replicate. EXAMPLE -: Influenza (influenza A and B viruses) and the common cold (rhinovirus) are examples of infections caused by viruses.

Bacteria: These are microorganisms which have a nucleus containing DNA surrounded by a cell wall or membrane. Among bacteria, the composition of the cell wall differs. If they are able to access food and nutrients, they have a more complex structure than viruses and can multiply beyond the host. EXAMPLE -: Foodborne diseases can be caused by bacteria such as Salmonella enterica and Escherichia coli, while Staphylococcus aureus can cause skin infections.

Fungi: Fungi are single-celled or multicelled species that can live outside a host. They consume food and nutrients created after digestive enzymes have been secreted into their atmosphere. example-:  The foot of the athlete (Trichophyton mentagrophytes) and yeast infections (Candida albicans) are examples of infections caused by fungi.

Prions: These are infectious agents made up entirely of proteins and capable of transferring to other prion proteins their infectious properties. EXAMPLE -: Extreme infectious diseases such as bovine spongiform encephalopathy (mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) can be caused by prions.

Protozoa: Protozoa are single-celled organisms that display habits that are similar to animals, such as the ability to travel through water, and are capable of harvesting other microorganisms. They are able to live outside the human host, but when they enter the human host and spread, causing infections and diseases, they may also be parasitic in nature.  EXAMPLE -: Malaria and giardia include common infections

Yes , pathogen enter into the body directly -: Direct contact infections spread when, through direct physical contact with blood or body fluids, disease-causing microorganisms move from the infected person to the healthy person. Touching, kissing, sexual contact, contact with oral secretions, or contact with bodily lesions are examples of direct contact.
INCUBATION PERIOD OF A PATHOGEN -:The period of incubation is the interval between exposure to a pathogenic organism, a drug, or radiation, and when the first signs and symptoms are evident.

During the S phase in the cell cycle, the chromosomes are replicated so that there are two copies. These copies are necessary so that each daughter cell created during the M phase will have an identical copy of the DNA.

Therefore, the answer is A: The DNA must be replicated.

The chromosomes joining, cell membrane expanding, and cytoplasm separating all happen during the M phase (mitosis).

Hawking states that much of human behavior has not been calculated to “aid in

ss7ja [257]

The complete statement made by Stephen Hawking is: "though much of its behaviour through out history, has been pretty stupid, and not calculated to aid the survival of the species."

If one looks at our history, there are some events that defy our capacity for logical thinking. One would think that, as we possess this capacity, we would be able to direct our decisions towards the survival of the human species.

However, in many cases greed and the desire for personal gain have taken precedence. One good example was the burning of the great library of Alexandria, one of the most significant libraries in the ancient world. This magnificent collection was lost during the siege of Alexandria, when Julius Caesar set on fire the ships in the harbor.

Another example is the atomic bomb, when science has been used to invent one of the most destructive weapons known to us. Atomic warfare is still a threat that may end all life on Earth.

Furthermore, the greed of some corporations has led to multiple ecological catastrophes that endanger not only other species but our own future as well. One example is the Bhopal gas leak in India, where in 1984, due to poor maintenance, the chemical plant released 30 metric tons of methyl isocyanite into the atmosphere.
