These defenses are described as nonspecific because they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.
Is innate immunity nonspecific resistance?
The innate immune system provides this kind of nonspecific protection through a number of defense mechanisms, which include physical barriers such as the skin, chemical barriers such as antimicrobial proteins that harm or destroy invaders, and cells that attack foreign cells and body cells harbouring infectious agents.
Thus, they do not target any specific pathogen; rather, they defend against a wide range of potential pathogens.

describe the five cellular targets of antibiotics, and explain antibiotics are effective against bacteria but not viruses.
Five cellular targets of antibiotics were exploited withinside the improvement of antimicrobial drugs: cell wall synthesis, protein , ribonucleic acid , (DNA) , and middleman metabolism.
How do antibiotics acts as resitance?The principal mechanisms of resistance are: proscribing uptake of a drug, amendment of a drug target, inactivation of a drug, and lively efflux of a drug. These mechanisms can be local to the microorganisms, or received from different microorganisms.
In principal, there are 3 principal antibiotic objectives in bacteria: The cell wall or membranes that surrounds the bacterial mobileular. The machineries that make the nucleic acids DNA and RNA. The equipment that produce proteins (the ribosome and related proteins).

Which environmental factor can lead to a decreases in the genetic variation of the population of tuna
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.

Homo erectus was likely the first hominid to successfully migrate to regions beyond Africa. Discuss how the biology and culture of Homo erectus led to its success on three major continents with varying environments.
Being the first designer of hand axes, stone fire, and other tools, Homo erectus was successfully established in other continents with varying environments.
What do you mean by Environment?The Environment may be defined as anything which is present in the surroundings of living organisms.
While making such tools for their use, they need proteins to survive and play their functional role. It leads to the mutation in their protein structure and behavior.
They used fire for cooking, heating their body during winter, and threatening away large predators.
Due to all these inventions, they successfully adapted to three major continents with varying environments.

With reference to the induced fit model, describe how the tertiary structure of a named enzyme facilitates its function as a biological catalyst
The induced-fit model includes the change in the conformational site of the substrate and enzyme. It is done till the enzyme completely binds the substrate. This will then activates the enzyme to perform its work.
What is induced fit theory?Induced fit theory or model suggest that the activation site of enzymes and the binding site of substrates undergo some conformational changes to fit into each other.
This binding results in activation of the enzyme and as the enzyme has a three-dimensional tertiary structure, this would help it to get fitted into the substrate.
Thus, with reference to the induced fit model tertiary structure of enzyme facilitates its function as a biological catalyst.
