Molecules in food contains chemical energy that cells use to produce MORE CELLS. This energy is gotten from the chemical bond energy in food molecules, which in this way serve as fuel for cells. The particles in food additionally give the atoms that animals need to develop new living matter.
A horseshoe crab has been around for almost 500 million years. They are classified as arthropods and not actual crabs. However, There are many reasons that have helped them survive this long including, they can eat almost any organic matter. There blood is different from normal, in fact it’s blue. This blood helps them heal any wounds right away. They can also live in areas with very low levels of oxygen, meaning habitat is not a big issue for them. Evolution has also helped them grow and adapt seeing as they’ve survived this long.
Hope that helps:)
Answer:
A) A decrease in Na+ permeability, and an increase in K+ permeability.
Explanation:
When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell K+ permeability while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels so as to restore the charge valance, that means that there is an increase in K+ permeability.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
Answer:
The celebrity of the defendant, the other major players, and the case itself had, and continues to have, society as a whole discussing domestic violence and the effectiveness of our laws that deal with this area of criminal law. Since the commission of the crimes in June of 1994, the Simpson' case brought to the forefront the issue of what role evidence of prior domestic violence should play in criminal prosecutions. In addition to the forensic evidence which the Los Angeles prosecutors relied upon to attempt to convict Mr. Simpson, the theory of the prosecution's case rested on the proposition that Mr. Simpson committed the murders against his former wife, Nicole Brown Simpson (hereinafter Ms. Brown), and her friend, Ronald Goldman, because of jealousy, obsession, and the need to dominate Ms. Brown. The prosecution's case rested entirely upon circumstantial evidence, and as such, the prosecutors sought to introduce evidence of Mr. Simpson's past abusive conduct toward Ms. Brown to establish the identity of the perpetrator and his motives to commit the brutal crimes. The prosecution argued that the history of domestic violence and prior threats were probative evidence of Mr. Simpson's motive, intent, plan, and identity as the killer. According to Los Angeles District Attorney Gil Garcetti, the trial judge's ruling on the admissibility of this evidence was the "most critical ruling" that the Court would make in the case The prior conduct which the prosecution wanted to introduce on its direct case included acts of physical beatings upon Ms. Brown by Mr. Simpson, some of which were documented by photographs showing Ms. Brown's injuries. Other incidents included an episode in which Mr. Simpson had thrown Ms. Brown out of a moving car; a 1989 assault for which Ms. Brown had been hospitalized due to her injuries; Mr. Simpson's 1989 no contest plea to spousal abuse for which he was ordered to undergo counseling and pay a fine; letters of apology for the abuse written by Mr. Simpson to Ms. Brown; Mr. Simpson's repeated threats to kill Ms. Brown; a 1993 recording of a "911" telephone call made by Ms. Brown to the police, during which the voice of Mr. Simpson was heard making threats and shouting obscenities at Ms. Brown; evidence that Mr. Simpson was stalking Ms. Brown, and that shortly before her death, Ms. Brown had made contact with a battered women's shelter help-line; and many other instances of actual and threatened violence committed by Mr. Simpson against Ms. Brown dating back to 1977. In January 1995, Judge Lance Ito, who presided over the murder trial, ruled that much of the domestic violence history would be admissible on the prosecution's direct case, including the 1993 "911" tape-recorded telephone call by Ms. Brown. The evidence was admitted to provide the jury with an appreciation of the "nature and quality" of the relationship between Mr. Simpson anji Ms. Brown, and to aid in establishing motive, intent, plan, and identity of the killer.
