Answers

Answer:

1. Respiration results in the production of energy and Breathing doesn’t provide energy.

2. Breathing is a biophysical process that involves the exchange of gases through inhalation and exhalation while respiration is a biochemical process to release energy from organic compounds which are then used for performing different physical activities.

Why are plants like grasse able to
reproduce more quickly than others?
A.) The pollen is able to spread with the wind farther and faster.
B.) The seeds are able to fertilize and grow in the soil at a faster rate.
C.) The root may grow horizontal rhizomes that make new shoots.

Answers

Answer:

C.) The root may grow horizontal rhizomes that make new shoots.

Explanation:

Plants like grasses able to reproduce more quickly than others because their roots grow horizontal rhizomes into a new shoots. These grasses spreads in the soil due to movement of rhizomes horizontally and grows its shoot with this movement. This spreading helps the grasses to make carpets in the grounds and has the ability to grow faster than other plants so we can say that growth of horizontal rhizomes is responsible for quick growth of grasses.

What is the benefit of using sunscreen when working outside every day?

Answers

Answer:

Not only does it protect from UV rays, it also works to reduce the appearance of pores and fine lines over time, so you're actually improving your skin while wearing it.

Explanation:

Answer:

It prevents cancer.

Explanation:

UV rays penetrate the many layers of the epidermis, reaching the deep layers of our skin, which is meant to be protected. This activates pigment cells, releasing Melanin and darkening the skin.

When the UV rays penetrate these deep cells, it reacts similarly to radiation, denaturing and breaking apart DNA. If enough damage is done and the cell becomes irreparable a tumor forms.

Consistent exposure to UV rays has detrimental effects because it puts your skin cells through this same stress every day.

Explain the process of photosynthesis in a plant in detail.

Answers

Answer:

Photosynthesis is the process through which plants convert light energy from the sun to chemical energy. The chemical energy is then stored as sugar. During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food).

Explanation:

The plant takes in carbon dioxide in the atmosphere through the stomata on its leaves. It is worth noting that there are some stomata on the stems as well.

Water gets into the plant mainly through the roots and finds its way to the leaves, where photosynthesis occurs. Plant roots are specially designed to draw water from the ground and transport it to the plant leaves through the stem.

Chlorophyll, the green coloring matter of the leaf, traps the energy from sunlight as it shines on the leaf. It is worth noting that it is chlorophyll that gives the leaf its green color.

The solar energy is used to break water down into hydrogen and oxygen. Then hydrogen is combined with carbon dioxide to make sugar, which is food for the plant. Oxygen is released as a byproduct through the stomata.

Answer:

The roots absorb water and nutrients. Water is carried to the leaf by the xylem in the stem. Carbon dioxide enters the leaf through the stomata. Energy from the sun is captured by chlorophyll in the chloroplasts. The process begins once these three reactants are present. Sunlight provides energy for a series of chemical reactions. Molecules break apart and join with other molecules to form glucose, which is a sugar or food for the plant, and oxygen, which is released into the air.

5. When is extinction of a species most likely to occur?
A)when environmental conditions remain the same and the proportion of individuals within the species that lack adaptive traits increases
B)when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce
C)when environmental conditions change and the adaptive traits of the species favor the survival and reproduction of some of its members
D)when environmental conditions remain the same and the proportion of individuals within the species that possess adaptive traits increases

Answers

Answer:

Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).

The extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.

What do you mean by Species?

Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.

If the members of species do not have adaptive traits to survive and reproduce, they will definitely become extinct in near future.

This is because the relative fitness is directly related to the appearance or existence of particular species in the habitat.

Therefore, the extinction of a species is most likely to occur when environmental conditions change and the members of the species lack adaptive traits to survive and reproduce.

Is the Amazon Rainforest Resilient or Fragile to change and why?

I thought Resilient because the rainforest has changed over time because it was fragile before.

Answers

Answer:

Resilient.

Explanation:

Amazon Rainforest is more Resilient to change because Amazon rainforest has evolved over millions of years. Amazon rainforests may be more resilient to climate change induced by carbon dioxide due to storing a lot of carbon as living biomass. The climate change is unable to change the Amazon rainforest due to their dense vegetation but if the rainfall patterns changes means the Amazon rainforest experience less rainfall due to climate change so it has a change this Amazon rainforests.

I keep getting syntax errors when I do the "add:" part. Can someone walk me through this code?Part A One of the biggest benefits of writing code inside functions is that we can reuse the code. We simply call it whenever we need it! Lets take a look at a calculator program that could be rewritten in a more reusable way with functions. Notice that two floats (decimal numbers, but they can also include integers) are inputted by the user, as an operation that the user would like to do. A series of if statements are used to determine what operation the user has chosen, and then, the answer is printed inside a formatted print statement. num1 = float(input("Enter your first number: ")) num2 = float(input("Enter your second number: ")) operation = input("What operation would you like to do? Type add, subtract, multiply, or divide.") if operation == "add": print(num1, "+", num2,"=", num1 + num2) elif operation == "subtract": print(num1, "-", num2,"=", num1 - num2) elif operation == "multiply": print(num1, "*", num2,"=", num1 * num2) elif operation == "divide": print(num1, "/", num2,"=", num1 / num2) else: print("Not a valid operation.") Your job is to rewrite the program using functions. We have already looked at a function that adds two numbers. Using that as a starting point, we could call the add function from within our program in this way: if operation == add: result = add(num1, num2) print(num1, "+", num2,"=",result) Now its your turn to do the following: Type all of the original code into a new file in REPL.it. Copy the add function from the unit and paste it at the top of your program. Write 3 additional functions: subtract, multiply, and divide. Pay careful attention to the parameters and return statement. Remember to put the three functions at the top of your Python program before your main code. Rewrite the main code so that your functions are called. Part B There are many different ways that a user could tell us that he or she would like to add two numbers in our calculator program. The user could type add, Add, ADD, or +, to name a few possibilities.
