For this activity, you will be creating your own Mad Libs game. It’s similar to the way you created the Introduction paragraph in the unit.


Start by typing out your Mad Libs fill-in-the-blank story in a word processing document. Make it as creative as possible! Identify whether your blanks should be filled by nouns, verbs, adjectives, or adverbs. Your story should include at least 10 blanks.

Next, transform your story into one big Python print statement in OnlineGDB using variables in place of the blanks.

Finally, create the variables you need for your template by putting them at the top of your program. You should use input statements to make the game interactive.

Test out your program thoroughly, fixing any syntax errors or bugs that arise.

Copy and paste the link to your code into the same document where you wrote your fill-in-the-blank story so that you have the regular fill-in-the-blank version and the code version.

They want you to use OnlineGDB

Answers

Answer:

b. base molecules from high concentration through the membrane to low concentration

Note: the complete question is found in the attachment below

Explanation:

The process which enabled the color change in the water and phenology mixture is known as diffusion.

Diffusion is the movement of molecules from regions of higher concentration to regions of lower concentration until equilibrium concentration is attained.

In the setup by the student, the concentration of the base molecules are higher in container than in the test tube. The vaporized molecules of the base therefore, moved through the membrane into the water and phenolphthalein mixture, resulting in the color change to pink in the mixture due to the reaction of the base and the phenolphthalein.

The correct answer is ''The scientific study of heredity''

Explanation:

Genetics is a branch of biology that studies how hereditary characters are transmitted from generation to generation and the diversity that exists among living beings. Inheritance is the physical and biological characteristics that we share with our family and that can determine our appearance and our biological characteristics, that is, our phenotype (eye color, skin type, etc.) as well as our internal characteristics. All of this is largely derived from our genetic components, that is, our genotype.

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes * 1 point solutes to move out of the cell. solutes to move into the cell. water to move out of the cell. water to move into the cell.

Answers

Answer:

water to move into the cell.

Explanation:

Osmosis is the process by which water moves from a region of low solute concentration (high water conc.) to a region of high solute concentration (low water conc.) across a semipermeable membrane. The movement of water is initiated by the formation of an osmotic gradient i.e. difference in concentration between the two sides of the membrane.

In this case, an animal cell is said to be surrounded by fresh water. This means that the solution in the animal cell is HYPERTONIC (high in solute concentration) to the solution in the extracellular environment, which is HYPOTONIC. This osmotic pressure causes water to move into the animal cell i.e. from the region of high water conc. (freshwater) into region of low water conc. (animal cell), causing the cell to burst.

The products that plants produce in photosynthesis are different from the products that animals and some bacteria produce in cellular respiration. The products of photosynthesis are

Answers

Answer: Carbohydrates in the form of glucose and oxygen as byproduct.

Explanation:

Photosynthesis is a process which occurs in green plants and in other autotrophs. In this process the autotrophs can prepare their own food by using reactants like water and carbon dioxide to produce glucose which is a carbohydrate which a major source of energy for plants and oxygen gas is released as a byproduct of this chemical reaction. On the contrary to this the cellular respiration can be defined as the process in which the biochemical oxidation of food occurs and energy is released in the form of ATP and carbon dioxide and water are produced.

Thus in photosynthesis the carbon dioxide and water are the reactants whereas in cellular respiration they are the products.

Which is a reactant in the Calvin cycle?
A. Glucose
B. Oxygen
C. Carbon dioxide
D. Water

Answers

C. Carbon dioxide


The inputs are carbon dioxide from the air and the ATP and NADPH produced by the light reactions. The Calvin cycle uses carbon from the carbon dioxide, energy from the ATP, and high-energy electrons and hydrogen ions from the NADPH. The cycle's output is an energy-rich sugar molecule.

The reactant of the Calvin cycle is the carbon dioxide that is present in Option C, and the product of the Calvin cycle is glucose. The Calvin cycle takes place during the photosynthetic reaction.

What is the role of photosynthesis?

Photosynthesis is a process in which the plant plays an important role, such as when the plant absorbs the sun's light, water, and carbon dioxide and then produces oxygen and glucose by combining all of these elements; thus, glucose and oxygen are the products, and water and carbon dioxide are the reactants. The water is used in the light-dependent reaction and converted into oxygen as a product, while in the case of the Calvin cycle or the light-independent reaction, carbon dioxide is used as the reactant and the product that is formed is glucose.

Hence, the reactant of the Calvin cycle is the carbon dioxide that is present in Option C.
