The arachnoid, a structure resembling a web and filled with fluid, is the middle layer and protects the brain. The durable outer layer is referred to as the dura mater.
What are the three dura mater layers?The brain and spinal cord are shielded by three layers of membranes called meninges. Pia mater is the thin inner layer. The arachnoid, a structure resembling a web and filled with fluid, is the middle layer and protects the brain. The durable outer layer is referred to as the dura mater.
Why is Duramat known as the "difficult mother"?Dura mater is defined. the topmost of three membranes, or meninges, that encircle the brain and spinal cord. Its Latin translation is "difficult mother." Due to the membrane's strength and thickness, which is typically firmly linked to the inside side of the skull, the term is appropriate.

Cell division is the process by which a parent cell divides into daughter cells.
Why is cell division important?Cell division is important as it helps in the production of identical copies of cell. It also helps in repairing the damaged tissues or cells that are worn out.
The difference between mitosis and meiosis is that mitosis results in two identical daughter cells while meiosis results in four se-x cells.
Mitosis creates diploid daughter cells while meiosis creates haploid daughter cells.
Lastly, the four main phases of cell division include prophase, prometaphase, metaphase, anaphase, and telophase.

gravity
Answers
Answer: Newton developed a mathematical formulation of gravity that explained both the motion of a falling apple and that of the planets. He showed that the gravitational force between any two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Explanation:
Answer: laws of motion, gravity
Explanation:
They were the only theories that were his.
Sir Isaac Newton, an English mathematician and physicist, developed three laws of motion that helped explain why the planets move the way they do. He also developed the first widely accepted theory of gravity, which also explained why objects in the solar system move the way that they do.

Early in genetic research, it was suggested that the genetic code might be made up of overlapping codons in which the last two bases of one codon make up the first two bases of the next codon, as below:
mRNA codons
overlapping code GGUAUA 1st codon = GGU
2nd codon = GUA
nonoverlapping code GGUAUA 1st codon = GGU
2nd codon = AUA
Supposing it were discovered that, in a life-form from another planet, even a single base pair substitution in the DNA caused three adjacent amino acid changes in the protein coded for. Would you conclude that the code was overlapping or nonoverlapping? Explain your logic.
Answers
The genetic code is called non-overlapping because adjacent codons can not overlap, whereas in this case, the code is overlapping.
What does 'overlapping code' mean?The genetic code does not overlap because the same nucleotide in the sequence cannot be used to encode two different codons.
In genetics, overlapping refers to a feature of the genetic code associated with how this nucleotide code is read.
In conclusion, the genetic code in this case is overlapping.

Why is the sympathetic nervous system referred to as the fight or flight system?
Answers
As you can see from the diagram below, the human nervous system is divided into two main components, the peripheral nervous system and the central nervous system.
The peripheral nervous system is further divided into two components. The somatic nervous system involves the voluntary movement of skeletal muscle. When you decide to raise your cup of coffee to your mouth, that is the somatic nervous system at work activating the appropriate muscles. The second component of the PNS is the autonomic nervous system, which controls processes that are out of our conscious control.
The autonomic nervous system is further subdivided into the parasympathetic nervous system and the sympathetic nervous system (which you are interested in). In very generalized terms, they have antagonistic effects on each other. The sympathetic nervous system generally activates the body, whereas the parasympathetic nervous system primarily acts to relax the body. This is a simplified view of things, but it is useful to think of it in this way.
The sympathetic division of the autonomic nervous system increases heart rate, inhibits digestion, relaxes bronchi in the the lungs to allow more airflow, causes the release of glucose from the liver, and relaxes the bladder. All of this activates the body, prepares it for a "fight".
In contrast, the parasympathetic division reduces heart rate, constricts bronchi in the lungs, and increases blood flow to the digestive tract. It has been called the "rest and digest" system.
As you can see from the diagram, the nerves of the parasympathetic nervous system come directly from the brainstem and spinal cord. However, with the sympathetic nervous system, there are "ganglia" (groups of cell bodies) outside the spinal cord itself.
Interestingly, the parasympathetic nervous system only uses Acetylcholine (ACh) to exert its effects on organs, but the sympathetic nervous system uses both ACh and norepinephrine (NE) to activate the body.
Its important to remember that the sympathetic and parasympathetic nervous systems are autonomic, meaning we generally have little control over them.

Answers
D. The measure of how stretched out an ellipse is, is referred to as eccentricity.
What is eccentricity of ellipse?
Eccentricity for an ellipse is the ratio of the length of the semimajor axis (a) to the distance (c )between the ellipse's center and each focus.
e = c/a
The greatest ellipse has the smallest eccentricity, whereas the perfect circle has the maximum eccentricity. The eccentricity of an ellipse e, which ranges from 0 (the limiting case of a circle) to 1 (the length of the ellipse), is used to determine how long it is (the limiting case of infinite elongation, no longer an ellipse but a parabola). Because the distance from the fixed point on the plane has a constant ratio that is less than the distance from the fixed line on the plane, the eccentricity of an ellipse ranges from 0 to 1.

What does this graph tell you about the concentration of salt inside the cell?
Answers
The concentration of salt inside the cell was lower than the concentration of salt in the salt water, since the cell got much smaller in size due to water outward movement.
What is osmosis?Osmosis is the movement of water molecules through a semi-permeable membrane from regions of low solute concentration to regions of high solute concentration.
If salt concentration is higher inside the cell than outside, water will move into the cells. However, if the salt concentration outside the cell is higher, water will move out of the cells.
The cell became smaller, indicating that water moved out of the cell.
Thus, the salt concentration in the cell was lower inside the cell.
