After cooking the hot dogs, your friend's mom reminds you not to leave the grill out, or the iron (Fe) in the grill will react with oxygen (O2) in the air to produce rust (Fe2O3). a. Write a balanced equation for this reaction. Be sure to show your work.
Answer:
Explanation:
Oxygen gas and water must be present for iron to rust.
A region of the metal’s surface serves as the anode, where oxidation
occurs:
Fe(s) → Fe²⁺ (aq) + 2 e⁻
The electrons given up by iron reduce atmospheric oxygen to water at the cathode, which is another region of the same metal’s surface:
O₂ (g) + 4H⁺ (aq) + 4 e⁻ → 2 H₂O (l)
The overall redox reaction is:
2 Fe(s) + O₂(g) → 4H⁺(aq) + 2Fe²⁺ (aq) + 2 H₂O(l)
The Fe²⁺ ions formed at the anode are further oxidized by oxygen:
4 Fe²⁺ (aq) + O₂(g) 1 (4 + 2x) H₂O (l) → 2 Fe₂O₃ . xH₂O(s) + 8 H⁺(aq)
This hydrated form of iron(III) oxide is known as rust. The amount of water associated with the iron oxide varies, so we represent the formula as 2 Fe₂O₃ . xH₂O.
Describe the steps in making, packaging, and exporting a protein from a cell.
Answer:
1. proteins are assembled on ribosomes
2. proteins targeted for export to the cell membrane, or to specialized locations within the cell. They complete their assembly on ribosomes bound to the rough ER
3. Newly assembled proteins are carried from the rough ER to the golgi apparatus in vesicles
4. the golgi apparatus further modifies proteins before sorting and packaging them in the membrane-bound vesicles
5. vesicles from the golgi apparatus are shipped to their final destination in or out of the cell

Explanation:
In the 1960s the molecular biologist George Streisinger developed the strand- slippage hypothesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand -slippage occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?
The insertion mutation affects the DNA cause Nitrogenous bases are added to the mix. This is further explained below.
What is a DNA?Generally, DNA is ssimly defined as a molecule found inside cells of a living organism that holds the genetic information.
In conclusion. Nitrogenous bases are added to the mix with the insertion of mutation.

Answer:
Explanation:
The black trait is a recessive trait because it only shows up in 3 people in that is rare. It also only occurs in either male or female looking at the shapes. The first part may be wrong but I believe that this is a Autosomal trait because it isn't occuring in every single person meaning it is a mutation.
I honestly hope this helps you.

In order to maintain homeostasis, the human body must be able to get rid of the waste products produced by cellular processes. The kidneys, for example, are responsible for removing waste from the bloodstream by producing urine. Urine produced in the kidneys then travels through the ureter and into bladder, and is finally expelled from the body by the urethra. The kidneys, ureter, bladder, and urethra help the body maintain homeostasis through the process of what?

There are four kinds of tissues in the human body. They are muscle, nervous, connective, and epithelial tissues. Which of the following is true about all of these tissues?
Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body

Simulation
Explanation:
In an experiment where you find something out without being there would be a simulation. Hope this helps :)
Without actually going into space to find out, simulation can be used. Thus option D is correct.
What is simulation in research ?Simulation is the re-enactment of real-world situation for different reason as it cannot be done in real due to several reasons.
This is completely conducted in a controlled environment which also the modification or addition of variable factor if needed.
The primary aim of this technique is to teach people with the appropriate steps to take in the event.
It is mostly used in cardiopulmonary resuscitation (CPR), science experiments, movies, sports, and video games.
It is used to identify what type of situation needs to be recreated and assess will be feasible, the goal for doing simulation should be decided, the device, model or parts need to be executed during simulation.

What is the difference between transpiration and diffusion
Answer:
In sunlight the concentration of water and oxygen molecules just inside the stomata is higher than the concentration of the air around the leaves so water vapor and oxygen diffuse, or move out, from the leaves through the stomata. Diffusion, then, is a physical driver of transpiration. Hope this helps!
