Cookware companies have been using a chemical called C-8, which helps to create a nonstick coating to pans. However, the Environmental Protection Agency (EPA) recently claimed that the use of C-8 in the manufacturing of nonstick cookware should be discontinued because studies show it causes cancer.
Who might benefit financially the most from the EPA’s claim?
Answer:
Explanation:
The choices provided are:
a.restaurants that use C-8-coated cookware
b.cookware manufacturers who make pans out of steel only
c.stores that sell C-8 nonstick cookware
d.individuals who use steel cookware at home
From these choices B is the correct answer.
Restaurants that use C-8 cookware will not profit from using it but will need to lose money by replacing the old C-8 coated cookware.
Stores that sell this nonstick cookware will also need to replace their inventory so they won't be making extra money, only losing it.
And individuals at home will still be using steel cookware and won't benefit or lose anything by this change with the regulations of the c-8 coated nonstick cookware.

Recovering Ecosystems Worksheet Section 1: Select the Kitakami River region, the Abukuma Highlands, or Japan's coastal habitat as the ecosystem you want to help with recovery. List the main problem faced by this ecosystem as described in the lesson. Then list at least two sub-problems that need to be considered to solve the main problem. List the sub-problems in order of most to least important. In the rationale column, explain why you placed your sub-problems in the order you selected. Main Problem Sub-Problems Rationale Section 2: Conduct internet research on your selected ecosystem to help you generate a list of three criteria and two constraints. Your criteria and constraints should consider relevant factors to the problem, such as costs, reliability, safety (to humans and wildlife), human needs, environmental impact, local biodiversity, and the aesthetics of the area. List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale column, explain why you placed your criteria in the order you selected. Constraints Criteria Rationale Which Sub-Problems does this criteria address? Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem. Sub-Problem Proposed Solutions Rationale Section 4: Answer the following analysis questions about your proposed solutions. Describe the ways your proposed solutions decrease the negative effects of habitat destruction and human activity on your selected ecosystem. Describe the costs, safety, and reliability of your proposed solutions, as well as any social, cultural, and environmental impacts your solutions address. Evaluate your proposed solutions for their impact on overall environmental stability and changes. Which solution has more impact? Explain your reasoning for picking one solution over another.

Both code for the proteins needed for reproduction of the structures.
Both provide energy for activities in the structures.
Both provide energy for activities in the structures.
This question is incomplete, here is the complete question:
A student produces a labeled drawing of a virus for a presentation. The student states that the capsid has a function similar to the nuclear membrane found in animal cells. Which of these describe the similar functions of capsids and nuclear membranes?
A. Both transport proteins throughout the structures
B. Both provide energy for activities in the structures
C. Both protect genetic information for the structures
D. Both code for the proteins needed for reproduction of the structures
The correct answer is C. Both protect genetic information for the structure.
Explanation
The capsid is the structure that protects and contains the genetic information of a virus, it is composed of proteins. On the other hand, the nuclear membrane of an animal cell is a structure that allows the cell to protect the DNA information, and to separate the chromosomes from the rest of the cell. According to the above, the capsid and the nuclear membrane of an animal cell have a similar function to protect the genetic information. So, the correct answer is C. Both protect genetic information for the structure.
Viruses are known to have different many shapes and sizes. The option that best describe the similar functions of capsids and nuclear membranes is that both protect genetic information for the structures.
The shapes of viruses are divided into four groups. They are;
FilamentousIsometric (or icosahedral) enveloped, head tail.The size and shape of a various can be determined by the amount and arrangement of the proteins and nucleic acid of the viruses. Note that the nucleic acid and proteins of each class of viruses often comes togetheer by themselves and form a structure called a nucleoprotein.

what are bony platelet?
Answer:
a minute colorless anucleate disklike body of mammalian blood that is derived from fragments of megakaryocyte cytoplasm, that is released from the bone marrow into the blood, and that assists in blood clotting by adhering to other platelets and to damaged epithelium — called also blood platelet, thrombocyte.
Similarly, you may ask, what is the medical term for platelets?
The medical term for having too many platelets is thrombocytosis, and there are two types: Primary or essential thrombocytosis – Abnormal cells in the bone marrow cause an increase in platelets, but the reason is unknown.
What is the medical name for platelets?
Platelet: An irregular, disc-shaped element in the blood that assists in blood clotting. During normal blood clotting, the platelets clump together (aggregate). Although platelets are often classed as blood cells, they are actually fragments of large bone marrow cells called megakaryocytes
Explanation:
Platelets are fragments of megakaryocytes, which are very large cells in the bone marrow. They aid in the formation of blood clots, which slow or stop bleeding and aid in the healing of wounds.
What is blood clotting?When a blood vessel is injured, blood clotting, or coagulation, is an important process that prevents excessive bleeding.
Platelets (a type of blood cell) and proteins in plasma (the liquid component of blood) collaborate to stop the bleeding by forming a clot over the injury.
Red bone marrow is responsible for the production of blood cells (hematopoiesis). Stem cells in your red bone marrow (hematopoietic stem cells) produce red, white, and platelets, which are all components of your whole blood.
Platelets are fragments of megakaryocytes, which are very large bone marrow cells. They promote the formation of blood clots, which slow or stop bleeding and aid in wound healing.
Thus, these are the main functions of platelets.

*****!!!! lots of points and brainliest!!!******** how do i find the codon and anti codon? :)
Answer:
The way to find a codon is by arranging the sequence of nitrogenous bases of the mRNA in groups of three, the triplets. Once the codon is found, the anticodon corresponds to a complementary triplet to that codon.
Explanation:
Codon corresponds to a triplet of mRNA nitrogen bases encoding an amino acid. Anticodon is responsible for carrying amino acids to the ribosome, according to the information of the mRNA, and the sequence of its triple must be complementary to that of the codon mRNA.
If, for example, a codon of the mRNA is AUG, its anticodon of the tRNA must be UAC, that is, complementary. Then, for the indicated exercises:
