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.

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.

the way a punnet square works is that you basically multiply two genes. for example:
b b
B Bb Bb
b bb bb
then, if it's uppercase, it is dominant. if it's dominant, it will take over the recessive gene. if it was Bo, B being brown and dominant, and o being recessive and orange, then brown would take over. there are also cases with codominant but that's not in the question. feel free to ask me anything about this.
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

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!

Humans have found that we can eat the space cow, and it's delicious! There are no laws currently in place protecting the environment of Planet Z. What would happen to the populations of both the Space Cows and the Vaderians if humans began to hunt for Space Cows on Planet Z?
Will it increase or decrease and why?
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.

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 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?
