Answer:
C) Plants
Explanation:
"Ecosystem" is the topic. Then "Plants" is the sub topic. Next the "Number of trees" and "Number of shrubs" branch out from there (Pun intended (; ).
Answer:
ring network
Explanation:
In a ring network, the nodes are arranged in a circular pattern where each node is connected to two adjacent nodes. In this topology, any node can communicate with any other node via the intermediaries.
In comparison,
- in a star network every communication needs to pass through a central hub node
- in a bus, each node is connected to a shared linear communication bus.
- in a hierarchical network nodes are organized along a tree structure layout.
[B] True.
In something like Microsoft Publisher, you are able to go to Insert -> Table, and specify the dimensions for the table you want.
Answer:
Gradient, in mathematics, a differential operator applied to a three-dimensional vector-valued function to yield a vector whose three components are the partial derivatives of the function with respect to its three variables. The symbol for gradient is ∇.
Explanation:
Answer:
- food_category = {
- "Fruits": ["Apple", "Strawberries", "Orange"],
- "Vegetables": ["Carrots", "Peas", "Onions"],
- "Meats": ["Chicken", "Beef", "Mutton"]
- }
-
- for cat in food_category:
- output = cat + ": "
- for food in food_category[cat]:
- output += food + ", "
- print(output)
-
- answer = input("Do you want to add category or food (Y - Yes N - No): ")
-
- while(answer == "Y"):
- choice = input("New Category (N) or New Food (nf): ")
-
- if(choice == "N"):
- new_cat = input("Enter new category name: ")
- if(new_cat not in food_category):
- food_category[new_cat] = ""
- elif(choice == "nf"):
- cat = input("Enter category: ")
- new_food = input("Enter new food name: ")
- food_category[cat].append(new_food)
-
- answer = input("Do you want to add new category or food (Y - Yes N - No): ")
-
- print("All food categories: ")
- for cat in food_category:
- print(cat)
-
- selected_cat = input("Select a category to view the food list: ")
- output = ""
- for food in food_category[selected_cat]:
- output += food + ", "
- print(output)
Explanation:
The solution code is written in Python 3.
Firstly, create a food category dictionary data structure (Line 1 -5). Next, display all the food category and the food in each category (Line 7 - 11)
Next prompt user to feedback if they wish to add new category or new food (Line 13).
While the answer is yes prompt user to enter their choice, either category or food and use if else if statements to handle the choice made by the user. If the choice is new category, prompt user to enter new category name and check if the new category is already exist in the dictionary. If not, add that category to dictionary (Line 18 - 21).
If the choice is food, nf, prompt user to input food category and enter the new food name and add it to the food_category list (Line 22 - 25).
After that prompt user to enter if they wish to continue to add new data (Line 27).
After collecting all info from user, write a for loop to display all the categories (Line 29 - 31).
At last, prompt user to select a category and display all the food of the selected category (Line 33 - 37).
