If the top level consumers were eliminated from a food web would the populations in the levels below them increase without bounds

Answers

Answer:

That isn't true

Explanation:

That is not true bc if the top level consumers were removed from the food chain, then the level below would become the top level of the food chain. If that happened then the level below the NEW top level of the food chain would still be getting eaten and the food chain still goes on, just with one missing level.

every time you see the ATP starburst or lighting symbol you should relate to it which concept

Answers

Answer:

The concept must be identified: that the energy currency for cells is ATP.

Explanation:

ATP is the abbreviation of the term Adenosine Triphosphate, the presence of its three phosphors and the dephosphorylation of them are the sources of chemical and electronic energy that our body and our cells need to be able to develop life.

The following reaction occurs in each ATP molecule used for energy purposes:

ATP + KINASE ----> ADP + P (inorganic)

Kinase is the enzyme that dephosphorylates the phosphorous molecules of ATP resulting in an ADP (adenosine diphosphate) and a free inorganic phosphorus.

Which of the following is NOT a difference between normal cell division and cancer
cell division?
O Normal cells recognize signals that tell them to stop and start the cell cycle, but cancer cells
do not
Normal cells can invade other tissues, but cancer cells cannot
In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated
O Normal cells communicate with each other, but cancer cells do not

Answers

B.Normal cells can invade other tissues, but cancer cells can not.

In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.

What is Apoptosis?

Apoptosis is the process in which cells are destroyed or killed for the purpose of controlling their development and growth. The normal cells follow this process but the cancer cell do not response to it and keep growing.

Normal cells can invade other tissues, but cancer cells cannot. In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated.The difference between a normal cell and a cancer cell is that a normal cells undergo while cancer cells don't Also, normal cells respond to signals while cancer cells don't.

Cancer cells are grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. Ignore signals that normally tell cells to stop dividing or to die which is the process known as programmed cell death.

Therefore, In normal cells, DNA is replicated correctly, but in cancer cells DNA is mutated. This is not a difference between normal cell division and cancer cell division. Thus, option B is correct.

Explanation:

No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote.

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\[/tex]

From the question

mass of metal = 1170 g

volume = 150 cm³

We have

[tex]density = \frac{1170}{150} = \frac{117}{15} = \frac{39}{5} \\ [/tex]

Which of the following statements best describes the philosophy of the Progressives? rest represent silence in music which is a quarter rest Finding Your evidenceCan parents go too far in supporting their childrens dreams? This is a questionpeople sometimes ask when they hear the story of the teenage mountain climber,Jordan Romero. Between the ages of 10 and 15, Jordan climbed the highest mountainon every continentand his father and stepmother climbed them with him. They callthemselves Team Jordan.Paul Romero, Jordans father, was taken by surprise when his 9-year-old sonfirmly announced his intention to climb the seven summits. Jordan had seen a mural atschool, showing the seven peaks that make up this pantheon of mountains. When hetold his father what he wanted to do, Paul Romeros jaw dropped. Paul Romero is anexperienced mountaineer, so he knew what was involved. He also knew his son.Weve always taught him to just think big and well try to make it happen, PaulRomero said. But, as Romero later noted, there was a fine line between encouraginghis son and pushing him too far. The father began by training his son so that he couldbegin to even understand what mountaineering wasthat theres this long, hard, dirty,un-fun hours and days and weeks of carrying packs and long, extensive, brutal travel,and all this type of stuff just before you can even think of climbing a mountain.Jordan persevered, though, and in July 2006, when he was 10 years old, Jordanand his family climbed 19,300-foot-high Mount Kilimanjaro, the highest peak on theAfrican continent. This was the first rung in the amazing ladder that Jordan Romero hadset out to climb. Over the next five and a half years, Team Jordan climbed Mount Elbrusin Russia (2007), Mount Aconcagua in South America (2007), Mount McKinley in NorthAmerica (2008), Mount Carstensz Pyramid in Indonesia (2009), Mount Everest in Asia(2010), and Vinson Massif in Antarctica (2011). In many of these climbs, Jordan set aworld record as the youngest ever to climb the peak. When he completed the sevensummits at 15, he was the youngest person ever to accomplish that feat.It was the Mount Everest ascentwhen Jordan was only 13 years oldthat hascreated the greatest controversy. Jordans feat as the youngest person to reach thetop of the world was publicized around the world. How Young Is Too Young? askedone newspaper headline. Many mountain climbers and medical experts questionedwhether a 13-year-old boy could climb so high (Mount Everest is almost 30,000 feethigh) without physically harming his body. Dr. Michael Bradley, a psychologist andexpert on teen behavior, noted, Most 13-year-olds dont have the wiring to makecognitive life-and-death decisions and are not truly able to understand what theyresigning on for. Another physician, Dr. Peter Hackett, reported that there are conflictingopinions about the effects on a young brain. Some theories say that a young brain ismore resilient; others say that it may be more vulnerable.Many climbers take exception to the publicity surrounding Team Jordan. Everestclimber Todd Burleson summed it up by saying, Hes got his whole life to climbEverest. Being the youngest boy to climb is a fashionable, celebrity-oriented sort ofthing. But its not about the mountains. Its like trying to get your PhD at ten. PaulRomero claims that he is fully aware of the risks. There is a fine line betweenencouraging Jordan and pushing him too far, he says. He talked about the point whereJordan might have reached his maximum mentally, physically, and where the risk hasbecome too high. He said, Jordan has just not even come close to that point yet.And what about Jordan, now that he has accomplished his goal of climbing theseven summits before his 16th birthday? Unsurprisingly, he has a new mission. He callsit Find Your Everest. In 2012 Team Jordan set out to encourage young people to beactive and healthy and to pursue their own adventures. In the process, he is invitingyoung people to join him in climbing the highest peak in each state. (They range fromDenali or Mount McKinley at 20,320 feet to Floridas greatest height345-foot-highBritton Hill!)I feel good about what my parents have taught me about setting goals, Jordansays.
