how does a change in concentration influence the diffusion of perfume
Answer:
Diffusion. Molecules are in constant motion and tend to move from regions where they are in higher concentration to regions where they are less concentrated. ... An example of diffusion in gases occurs when a bottle of perfume is opened at the front of a room.

Describe the natural process that creates a human clone.
Answer: Natural cloning also occurs in animal organisms during processes such as budding (offspring grows out of the body of the parent), fragmentation (the body of the parent breaks into distinct pieces, each of which can produce an offspring), and parthenogenesis. In humans and other mammals, the formation of identical twins is a type of natural cloning.

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.

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.

Does the plant use all wavelengths of light to carry out photosynthesis? Why does this make plants look green?
Answer:
Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. ... All photosynthetic organisms have chlorophyll a which absorbs violet-blue and reddish orange-red wavelengths. Chlorophyll a reflects green and yellow-green wavelengths. Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.

Mutations rarely occur.
No ones helping me. Only answer if you know :( Due by the end of today
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.

if humans begin hunt the space cows they will eventually become extinct causing the vaderians to lose a main source of food which would most likely cause their population to also decrease.
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?
