The human circulatory system is efficient because we were created with a system to be as efficient as possible. The circulatory system is basically a highway made of tunnels that allows RBC’s and WBC’s to pass through to every part of the body including major organs.

Compare the nervous system of the shrimp to that of a vertebrate.
Answers
Answer: The majority of animals on our planet, about 95 percent, do not possess a true backbone and are called invertebrates. It's common knowledge that vertebrates like humans have a complex nervous system that reacts to stimuli, but much less is known about invertebrates like shrimp and insects. While it's somewhat different from that of vertebrates, shrimp do have a central nervous system comprised of four main parts.
Explanation:
The nervous system is a highly specialized organ found in vertebrates.
The nervous system
The nervous system is a complicated system in the body of a vertebrate that is made up of the peripheral nervous system, which includes cranial nerves, spinal nerves, involuntary nerves, etc., and the central nervous system, which includes the brain and spinal cord.Neurons in the nervous system primarily relay signals to the various bodily parts.Somatic and visceral components are part of the peripheral nervous system.The two halves of the vertebrate nervous system are the grey matter and the white matter.The central nervous system and the peripheral nervous system make up the nervous system.The spinal cord and the brain, which regulate all bodily functions, make up the central nervous system.The cranial and spinal nerves, on the other hand, are part of the peripheral nervous system, which links the central nervous system to the rest of the body.Nerves carry electrical impulses from the skin and other sensory organs to the brain, which interprets the stimuli and delivers a reaction to the muscles and glands of the body.learn more about it

*****!!!! lots of points and brainliest!!!******** how do i find the codon and anti codon? :)
Answers
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:

Part C
Projected values are only estimates. Can you think of either a natural or artificial factor that could increase or decrease the actual amount of wind energy the United States produces in the future?
Edmentum sample explanation:
Technological advancements in the future could lead to the production of higher-efficiency turbines, which could generate more electricity than originally predicted. Climate changes over time could affect wind speeds in a region, leading to higher or lower energy production.
The factors that would exert influence through the process of natural selection are a natural selection: diseases; artificial selection: and genetic engineering. The correct option is C.
What is natural selection?The strongest survive through natural selection, and the most favored traits endure through evolution. Natural selection is the result of selection pressure on a population's frequencies of a specific allele. Evolution is the process through which, over an extended period of time, new sets of naturally selected organisms emerged.
Future technological developments might result in the creation of turbines with a higher efficiency, which might produce more electricity than was initially anticipated. Wind speeds in a place may alter as the climate shifts through time, which could result in increased or decreased energy output.
Therefore, the correct option is C. natural selection: diseases; artificial selection: genetic engineering.

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.

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?
Answers
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.

what are bony platelet?
Answers
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.
