Explain where most of your food originally came from and how your cells obtain and use that food.
Most of the food we eat comes from plants, either directly or indirectly. Plants are able to use energy from the sun to convert carbon dioxide and water into glucose, which can be used as food by both plants and animals. Humans obtain their food by consuming plants, such as fruits, vegetables, grains, and nuts, or by consuming other animals that have eaten plants.
Once we eat food, our digestive system breaks it down into nutrients, such as carbohydrates, proteins, and fats, which are then absorbed into the bloodstream. These nutrients are transported to cells throughout the body, where they are used for energy, growth, and repair.
The cells in our body use a process called cellular respiration to convert glucose and other nutrients into ATP (adenosine triphosphate), which is the primary source of energy for cellular processes. During cellular respiration, glucose is broken down into carbon dioxide and water, and energy is released.
For example, proteins obtained from food are used to build and repair muscles, while vitamins and minerals obtained from food are necessary for various physiological processes, such as blood clotting, immune system function, and bone health.
Overall, the food we eat provides the necessary nutrients and energy for our cells to carry out their functions and keep our bodies functioning properly.

Rusting of iron and cutting an onion are both examples of chemical changes.
How to explain the chemical changeRusting of iron is a chemical change because it involves a reaction between iron, oxygen from the air, and water. The iron reacts with oxygen to form iron oxide, commonly known as rust. This process is irreversible, and the chemical composition of the iron is altered during rusting.
Cutting an onion is also a chemical change because it involves the disruption of the onion's cell structure and the release of enzymes. When you cut an onion, enzymes stored within the cells are released, reacting with certain compounds to produce sulfur compounds. These compounds are responsible for the pungent smell and the tears that occur when cutting an onion. The cutting process causes a chemical transformation in the onion's composition, making it a chemical change.

What result allowed Dintzis to conclude that proteins are synthesized from the N terminus to C terminus
Answer:
The more newly synthesized peptides had greater levels of radiolabeled H
Explanation:
Using immature red blood cells (reticulocytes), Dintzis showed that polypeptide chains of hemoglobin were created from N-terminal to the C terminus during translation. Dintzis labeled with radioactive amino acids that were being actively translated, subsequently digested the translated proteins with trypsin and finally determined the amount of tryptic protein fragments. From this experiment, Dintzis observed that the radioactive products were concentrated in the C-terminus (i.e., labeled amino acids appeared first in the C terminal tryptic peptides), thereby showing that the direction of protein synthesis is from the N terminus to the C terminus.

Draw a model showing what would happen if poison blocked our cell ability to make tRNA (Specifically draw a model)
Answer:
Here is a model showing what would happen if poison blocked our cell ability to make tRNA:
[Image of a cell with a large red X over the tRNA]
tRNA is a type of RNA that is involved in protein synthesis. It helps to carry amino acids to the ribosome, where they are assembled into proteins. If poison blocked our cell ability to make tRNA, it would prevent us from making proteins. This would lead to a variety of health problems, including:
* Muscle weakness
* Weight loss
* Fatigue
* Hair loss
* Skin problems
* Infections
* Death
In severe cases, blocking tRNA production can be fatal.
Here is a more detailed explanation of how tRNA works:
When a cell needs to make a protein, it first reads the DNA code for that protein. This code is transcribed into messenger RNA (mRNA). The mRNA is then translated into a protein by the ribosome.
The ribosome reads the mRNA codon by codon. Each codon is a sequence of three nucleotides that codes for an amino acid. The ribosome uses tRNA to bring the correct amino acid to the ribosome for each codon.
The tRNA molecule has an anticodon that matches the codon on the mRNA. The anticodon is a sequence of three nucleotides that is complementary to the codon on the mRNA.
The tRNA molecule binds to the ribosome at the codon that it matches. The amino acid that is attached to the tRNA is then added to the growing protein chain.
This process continues until all of the codons on the mRNA have been translated. The ribosome then releases the protein chain.
If poison blocked our cell ability to make tRNA, it would prevent the ribosome from getting the correct amino acids for each codon. This would result in the production of faulty proteins. These faulty proteins could damage the cell or even kill it.

Allergies, such as those caused by pollen, occur when a specific type of immune cell recognizes that pollen is an allergen for which to create antibodies.
A substance that can trigger an allergic reaction is known as an allergen. The immune system of some individuals perceives allergens as threatening. In order to protect itself from the allergen, the immune system responds by producing a particular form of antibody known as IgE. Allergy symptoms result from this response.
The immune system's defense mechanisms include keeping harmful bacteria, viruses, and fungi out of the body and eradicating any infectious microbes that do get inside.
Allergens can enter the body through the skin, mouth, or respiratory system. Immunoglobulin E (IgE) is a kind of antibody generated by the body that has been related to common allergic reactions such as fever, some types of asthma, and hives. Each IgE antibody can respond quite specifically to particular allergens and pollens.
The immune system recognizes pollen as an allergen or intruder if someone has a pollen allergy. Immunoglobulin E (IgE) produces antibodies when the immune system overreacts.
Hence, the correct answer is an allergen.
