Answer 1

Answer:

thats crazyyyy

Explanation:

Answer 2

Woolly mammoths developed thick fur and large ears to survive in cold climates through natural selection.

The cold climate of the Pleistocene epoch favored the survival of animals that were well-adapted to cold weather. Woolly mammoths had thick coats of fur that helped to keep them warm, and they also had large ears that helped to dissipate heat. Woolly mammoths had a long trunk.

The trunk of the woolly mammoth was used for a variety of purposes, including gathering food, drinking water, and communicating with other mammoths. The trunk was also a valuable tool for helping the mammoth to survive in cold weather.

For example, the mammoth could use its trunk to blow snow away from its food or to reach food that was buried under the snow. Woolly mammoths were social animals. Woolly mammoths lived in herds, which helped them to survive in cold weather. The herds provided protection from predators and helped to keep the mammoths warm.

Imagine an animal cell lost half of its mitochondria. Explain how the cell would be different.
YOU WILL GET 100 POINTS.

Answers

Answer:

Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. ...

Explanation:

Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.

mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found; an apparent case of endosymbiosis. Scientists hypothesize that millions of years ago small, free-living prokaryotes were engulfed, but not consumed, by larger prokaryotes, perhaps because they were able to resist the digestive enzymes of the host organism. The two organisms developed a symbiotic relationship over time, the larger organism providing the smaller with ample nutrients and the smaller organism providing ATP molecules to the larger one. Eventually, according to this view, the larger organism developed into the eukaryotic cell and the smaller organism into the mitochondrion.

in most animal species, mitochondria appear to be primarily inherited through the maternal lineage, though some recent evidence suggests that in rare instances mitochondria may also be inherited via a paternal route. Typically, a sperm carries mitochondria in its tail as an energy source for its long journey to the egg. When the sperm attaches to the egg during fertilization, the tail falls off. Consequently, the only mitochondria the new organism usually gets are from the egg its mother provided. Therefore, unlike nuclear DNA, mitochondrial DNA doesn't get shuffled every generation, so it is presumed to change at a slower rate, which is useful for the study of human evolution. Mitochondrial DNA is also used in forensic science as a tool for identifying corpses or body parts, and has been implicated in a number of genetic diseases, such as Alzheimer's disease and diabetes.

Answers

Answer:

The correct answer is A. real-time PCR can measure the amount of DNA amplified as the reaction proceeds, while standard PCR cannot.

Explanation:

PCR (Polymerase Chain Reaction) is a molecular biology technique. Conventional PCR and real-time PCR are diferent types of PCR, and are both used to exponentially amplify DNA molecules. In both types, a polimerase enzyme is employed to sinthesize DNA copies. The main difference is that conventional PCR is qualitative whereas real-time PCR is quantitative. So, real-time PCR permits not only to detect and amplify DNA but also permits to perform a quantification of the target DNA. This is accomplished by measuring a fluorescence signal - which is directly the amount of DNA amplified- during the course of the reaction.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).

Answers

Answer:

Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.

Identify four of Jerusalem's holy sites. To which religion is each site sacred, and why is it considered important?Holy Sites of the Ancient City of JerusalemJerusalem is one of the oldest cities in the world. People settled there about 3,000 BCE. The area has been occupied ever since. Today, Jerusalem is located in Israel. The city is a holy place for people of three world religions. There are many sites in the city that are important to the faiths of Islam, Judaism, and Christianity.Temple Mount, the Dome of the Rock, and El Aqsa MosqueTemple Mounta large, walled, stone plaza on a hilltopis one of the most important spiritual sites in Jerusalem. It is called Al-Haram al-Sharf in Arabic, which is the language of Islams holy book called the Quran. Temple Mount is so large that hundreds of thousands of people can visit the site at the same time. This is important because Muslims (followers of Islam), Jews, and Christians all consider Temple Mount a holy place.Muslims believe that this site is the place where Muhammad, the prophet and founder of Islam, ascended to heaven. The oldest existing Islamic monument, the Dome of the Rock shrine, was built on Temple Mount. The shrine is called Qubbat al-akhrah in Arabic. It was completed in 692 CE. The Al-Aqsa Mosque is also located on Temple Mount. This place of Muslim worship is the largest mosque in Jerusalem. Al-Aqsa can accommodate more than 4,000 worshippers at once. Muslims consider the entirety of Temple Mount a mosque. It is their third most important spiritual site, after Mecca and Medina.The Dome of the Rock also marks an area important in the Jewish tradition. Jews believe that Abrahamthe patriarch of the Hebrewsprepared to sacrifice his son Isaac at the site.The First and Second Temples and the Western WallIn Hebrewthe language of the Jewish holy book, the TorahTemple Mount is called Har Ha-Bayit. To Jews, Temple Mount is the site of the First and Second Temples, Jewish places of worship in ancient Israel that were destroyed in conflicts. Parts of the walls that surround Temple Mount were built to support the Second Temple. The Western Wall, which is also called the Wailing Wall or the Kotel, is one of these walls. It is the most important Jewish spiritual site, and Jews worship here daily.To Christians, the Temple Mount is important because it played a central role in the life of Jesus Christ. He was a Jewish religious leader whom Christians consider the incarnation of God. Christians believe that Jesus prayed and taught at the Second Temple.The Church of the Holy SepulchreThe holiest site for Christians is the Church of the Holy Sepulchre in Jerusalem. Christians believe that at this site, Jesus Christ was crucified on a cross and buried in a nearby stone tomb. (The word sepulchre means tomb.) Three days later, they believe, he rose from the dead at this spot. The Church of the Holy Sepulchre contains more than 30 chapels and places of worship. The most important is the Tomb of Christ, also called the Edicule. Another is Golgotha, the rock where Jesus Christ was crucified, which was enclosed within the church sometime after his death.
