are worm neurons alive????
Answer:
Yes
Explanation:
In the inner-world perspective of the simulation, the worm is absolutely alive as it is obeying the laws of physics as presented by the simulation.
Answer: Yes
Explanation:
Growing to just one millimeter in length, these simple creatures have only 302 neurons, or nerve cells, in their bodies, a tiny fraction of the 80 billion or so neurons in the human brain. ... They found the circuit has "command neurons" that release serotonin to increase movement in the worms.

Read the passage about the fluoridation of drinking water.
Since the early 1960s, fluoride has been added to many sources of drinking water to prevent cavities in teeth. This is called fluoridation. There are some who say that this is unnecessary and increases the risk of cancer.
In 1993, the Subcommittee on Health Effects of Ingested Fluoride of the National Research Council, part of the National Academy of Sciences, conducted an extensive study about the link between fluoridated drinking water and increased cancer risk. The study included data from more than 50 human disease studies and six animal studies. The Subcommittee concluded that none of the data showed a link between fluoridated drinking water and cancer. A 1999 report by the CDC supported these findings. The CDC report concluded that studies so far have produced "no credible evidence” of a link between fluoridated drinking water and an increased risk for cancer.
According to the article, what valid claim came from the National Research Council?
A. There is no link between fluoride exposure and increased cancer risk in humans.
B. There is a possible link between fluoride exposure and increased cancer risk in humans.
C. There is a definite link between fluoride exposure and increased cancer risk in humans and animals.
D. There is a possible link between fluoride exposure and increased cancer risk in animals.
Answer: A. There is no association between fluoride exposure and increased cancer risk in humans.
Explanation: just did it.
What is the evidence that supports the autogenic hypothesis?
Answer:
Explanation:
The hypothesis is supported by the studies on mitochondria. The mitochondria contains its own DNA and sythesizes many of its RNA and proteins. The mitochondrial protein synthesis machine, the ribosomes are similar to those found in bacteria. Similar to the bacterial cells, the mitochondria also contain circular genome

The model shows a nucleic acid. Which is one function of the nucleic acid? It helps code for proteins. it help synthesize DNA It provides energy to the cell.. It helps synthesize DNA. It helps synthesize DNA. It is a major component of the cell membrane. It is a major component of the cell membrane.
Answer:
The correct answer is - It helps code for proteins.
Explanation:
Nucleic acids are biomolecules that are essential for all life forms, they are of two major types RNA and DNA. In RNA the sugar is ribose whereas in DA deoxyribose sugar is present.
Nucleic acids are helpful in protein synthesis in both types of cells and all organisms. These biomolecule codes for the protein and makes the polypeptide chain made up of amino acids with the help of mRNA and tRNA with ribosomes.

Your science class has taken swabs throughout the school. The image shows the petri dish containing a bacterial culture that developed from a swab of one computer keyboard in the classroom. You would like to make a detailed observation of the internal structures of the bacteria in your culture. You know that In order to see just their shape, it is necessary to use a magnification of about 400x to 1000x. Based on this, develop a logical argument for using a transmission electron microscope.
The TEM magnifies 1,500,000X and produces a 3D image.
In order to keep the students safe, the bacteria must be dead before viewing with any microscope.
The TEM magnifies up to 2000,000X and you can see great detail including the internal structure of cells.
The TEM produces a 2D image of whatever specimen you are viewing.
A logical argument for using a transmission electron microscope (TEM) is: C. The TEM magnifies up to 2000,000X and you can see great detail including the internal structure of cells.
What is a microscope?A microscope can be defined as an optical device that is typically designed and developed to produce an enlarged (magnified) image of a minute (very small) object, in order to show all the littlest and tiniest details about the object that cannot be seen by the natural human eye.
The types of microscopes.In Science, there are different types of microscopes and these include the following:
Scanning electron microscope.Polarizing microscopeInverted microscopeCompound light microscope.Transmission electron microscope.Ideally, a magnification of about 400x to 1000x is required to see the shape of a bacterial culture. However, a transmission electron microscope (TEM) can magnify up to 2000,000X and as such you can see great detail of a bacterial culture, including the internal structure of their cells.

Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm.

How might using a model help develop the design?
Answer:
The correct answer would be - it could be tested in a lab.
Explanation:
A model is a smaller representation or test unit for an idea, or a process that is which is used to test or explain the idea or process that can not be made multiple times on a large scale.
Developing a new method to heat an airplane's windshield to prevent it from ice accumulation when in flight, testing this new idea, is very risky in the actual plane during flight so testing this method in the lab on a model would be helpful.
