Charles Babbage is known as the father of computer.

Answer is A, searching information

Plants are able to make their own food through photosynthesis, thus are called Autotrophs. As animals are unable to synthesise their own food and organic material, they depend on plants and attain plant's complex organic material by consuming the plant. As a result animals eating plants are herbivores. The animals that cannot directly consume plants, depend on these herbivores for the complex organic material and energy, and are called Carnivores.

Step1. Scan a number

Step2. if number less than zero (0)

Step3: Inform user number is negetive 

Step 4. End

Carl Linnaeus was a swedish botanist/zoologist and physician. He is also known as the father of modern taxonomy.

Animals that can breathe on both (land & water) are called Amphibians.

For example:- frogs, salamanders & toads etc.

First thing to understand is the Resource Pool. As the name suggests, it can be visualized as a group of available CPU and memory resources, that can be shared among different processes. Through a resource pool, such resources can be effectively managed by maintaining for what the particular resources is reserved for, any limit details, and which other processes share the resource.

Now the Operating System is referred to as a 'Resource Allocator', as it allocates resources from the Resource Pool to various processes/programs as requested and/or required before the initiation of the process.

When a process/program is initiated, OS checks the Resource Pool to see if the required resources (CPU, memory) are available in the pool. If the resource(s) is/are free, it allocates them to the requesting program and updates the Resource Pool with the allocation status.

As and when a process completes, the OS de-allocates the resources assigned to it and add it back to the Resource Pool and re-assigns to any other process as per the need.

Please do let me know if this was helpful.

Let's understand the pros & cons of C programming in a simple way.

Pros:-

1) Portable language:- Since it is based on ASCII characters, it is compatible with a wide range of operating systems and platforms, for example, Windows, Linux, Mac OS X, Android, and iOS.

2) Simple 2 write

3) Simple 2 debug

4) Dynamic memory allocation - It implies that we have complete freedom to allocate memory at run time.

Cons:-

1) It doesn't support " Inheritance ".

2) Concept of OOPs - Like point no. 1, it doesn't support the concept of OOPs like Polymorphism, Encapsulation, Abstraction, and Data Hiding as well.

3) Run time checking - unlike other programming languages, it shows errors after the compilation. Which is not at all good for large codes of programs.

We hope it will clear your query.

Thanks

Hydrophytes - They are plants which are adapted to live in aquatic environments. They can  be fully or partially submerged or can be floating in water. They have special adaptations which help in their survival in water. For example, they have spongy tissue in stems, roots and leaves which creates air spaces and allows exchange of  gases. They also have floating leaves with long dissected petioles to prevent water flooding. Stomata in these plants can be absent or are always open if present. This is because they dont have the requirement to save water. Xylem vessels in these plants are poorly developed. Example:  Hydrilla .

Xerophytes -  They are plants which are adapted to  dry conditions. They have adaptations which help them in preventing water loss and store water. When they store water, such plants are called succulents which is possible due to presence of thick, fleshy stems. They also have waxy coatings on leaves which help them to prevent water loss. Some other adaptations which help them to prevent water loss are dropping of leaves during dry periods, folding or repositioning of leaves to prevent loss of water through excess sunlight exposure, hairy coverings on leaves. Examples - cacti, agave.
