Give yourself a minute to "catch" the "prey" with each "predator" separately (total of 3 minutes). Place each "prey" that is caught into a cup. Count your results after each "predator" simulation.
Which prey was the best adapted? What data do you have to support this?
In what ways does this activity demonstrate the process of natural selection and its consequences?
The activity demonstrated natural selection as the beans will most likely survive since they are better suited to their environment .
What is natural selection?Natural selection is the process which organisms which are better adapted to their environment survive and reproduce while those not adapted die.
In the simulation, the "prey" are beans, uncooked pasta, and cotton balls. The predators are fork, knife, and a spoon.
Using the predators to pick up the prey, the beans were more adapted as they escaped being caught the most, as they had the least number picked up.
Therefore, the beans will most likely survive, demonstrating natural selection which states that organisms better suited to their environment survive the most.

Atrazine is an herbicide that prevents plant growth by inhibiting photosynthesis. Atrazine works by binding to proteins in the electron transport chain of photosystem II. Once atrazine binds to the proteins, electrons can no longer travel down the chain to reach photosystem I.
Based on this information, how does atrazine stop plant growth?
A.
It prevents water from releasing oxygen, which is needed by the light-dependent reactions to fix carbon.
B.
It prevents the formation of NADH and FADH2, which are needed by the light-independent reactions to fix carbon.
C.
It prevents chlorophyll from creating electrons, which are needed by the light-dependent reactions to make sugars.
D.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
It prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars. Thus, the correct option is D.
The herbicide atrazine binds to the D1 protein and prevents plastoquinone from binding. By preventing plastoquinone from binding, the photosynthetic transport of electron is disrupted, putting the generation of ATP and NADPH in the chloroplast at risk.
What are herbicide?
Herbicides are chemicals that are used to control or manage unwanted vegetation. Herbicides are most commonly used in row-crop farming, where they are treated before or during planting to increase crop productivity while reducing other vegetation.
This results in the plant's inability to fix carbon dioxide and provide the nutrients it needs to survive. A halt in electron transmission causes oxidative stress and the generation of radicals, which leads to rapid cellular death.

Describe the hearing process
So to put this in a question, I would rephrase it to:
How does hearing work?
It's a little tough to ELI5 without using using the names of the particular organs but here goes:
Sound is nothing more than a wave of air pressure. In other words, it fundamentally involves changing degrees of energy-based air pushing and tugging. Additionally, it is because to this that sound cannot travel in a vacuum. When these waves reach your ear, they first come into contact with the "tympanic membrane," which vibrates and transmits these vibrations to the malleus, incus, and stapes, three small bones (Latin for hammer, anvil, and stirrup).
The waves will subsequently be transmitted via the bones' vibrations to the "cochlea," a spiral-shaped organ filled with fluid. The air pressure wave has so undergone many transformations at this point. Air pressure was followed by mechanical vibrations and is now "fluid pressure." The spiral-shaped cochlea is lined with neurons all the way around. Depending on the fluid pressure waves' intensity, frequency, etc., the cochlea will have to travel a particular distance. Based on these fluid waves, these neurons will then activate, sending information to your brain.
Your brain then decodes these messages to produce the "sound" that you hear. Although I'm not convinced this is the greatest ELI5, this is the main idea.
In essence, your ear works as follows:
Air pressure waves enter the ear, transform into mechanical vibrations, transform into fluid pressure waves, which signal neurons and cause those neurons to fire electrical impulses that communicate with the brain the sound you are hearing.
Cheers,
ROR
Answer:
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

GENES are the fundamental unit of heredity that transmit albinism from one generation to the next. Thus, the correct option is A.
What is DNA?Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce.
Because they contain unique sets of instructions to encode certain proteins, which are passed down across generations, genes are regarded as the fundamental functional and structural components of heredity (i.e., they are inherited).
When a gene is expressed, certain DNA fragments (i.e., genes) are used as templates to produce messenger RNAs (mRNAs), which are complementary RNA sequences.
