Why is it important for there to be different species in an ecosystem? What would happen if all the species were the same? Explain why biodiversity matters.
Answer: Biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines. If all animals in an ecosystem were of the same species, the balance would be lost.
Explanation:
An ecosystem is a set of living beings (of different species) that share the same habitat or biotope. There are first of all primary producers, those that are capable of producing organic matter from inorganic compounds. These organisms are autotrophs, such as plants. Then we find in the second step the consumers, heterotrophic organisms (herbivores, carnivores or omnivores) that feed on matter and energy produced by other living beings. And in the last link of the trophic chain of organisms that make up an ecosystem we find the decomposers, those that feed on dead organic matter. In this way, there are complex interactions between different organisms of different species.
Thus, biodiversity is the variety of life, which is responsible for ensuring the balance of ecosystems around the world. It provides necessary goods such as food or oxygen, it provides raw materials that favor economic development, it produces energy that we use as fuel, and it is the origin of some medicines.
If all animals in an ecosystem were of the same species, the balance described above would be lost. If they were all producers like plants, there would be no consumers to control the plant population. If they were all consumers, they would eventually run out of food. And if they were all decomposers, they would not have enough dead organic matter to feed on either. A greater number of species or biological diversity in an ecosystem makes it more resilient. Because species can absorb and reduce the effects of environmental changes on the overall structure of the ecosystem. In addition, they can reduce the chances of a change to a different state.
List the three parts of the cell cycle.
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

okay , so I am 13 years old . I had gotten my cartilage pierced on both ears for my 13th birthday. Fast foward, I had asked my mom if I could get another cartilage piercing and my tragus pierced . She told me to ask my father. I did not . So I had pierced my tragus and my cartilage on my ear .. And my mom nor my dad has no clue I done it .
I just feel guilty hiding it from them , more so my mom ..
Can anyone give me advice on how to tell them PLEASEEEEEEEEEE
Answer:
its better to tell them now, you will most definitely get in trouble for it but it'll be better than them finding out later. simple.
Okay, so the best thing to do is to tell them. They're going to find out eventually so it's better for them to hear it from you so they know you've learnt from your mistake rather than them finding out and wondering what other things you have to hide and also, you're 13, how did you get a piercing without parent permission required?
In this case, we have a large population of lizards that live on an island. These particular lizards can either have an all-green tail or a tail with a black tip. In the large population there are many of each type, but one day, two green-tailed lizards and three lizards with black-tipped tails were picked up by a sailor and dropped off on an island that had no lizards of this kind. It was noted that the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators. The lizards began to breed and eventually produced their own large population after a few years. Make a prediction about what you might find if you visited this island after several years based on what you have learned.
PLEASE HELP!!!
This is a complicated question that's a little easier if you break it down!
Island One:
- Lizard tails are all green or black tipped.
- This island has many of each type.
Sailors Moved:
- two green-tailed lizards
- three black-tipped lizards
On Island Two, we know that the black-tipped lizards are more likely to survive since the question tells us that "the black-tipped lizards could use the black tip of their tail to distract predators while they made a quick escape and this particular island had many predators".
The green tailed lizards do not have this advantage, and the predators are eating more of them because of this (especially if there are a lot of predators!).
We also know that the lizards on the island were able to reproduce and form a large popuation- not all of them were eaten by predators.
Based on this information we can predict:
There are going to be a lot more black tipped lizards (or they may all be black tipped lizards) because they have an advantage in surviving longer.
Which best describes the lower body structures of humans and chimpanzees?
The big toes of humans and chimpanzees are enlarged.
The human foot has three arches, but the chimpanzee foot only has one.
Human knees are very mobile, but chimpanzee knees are stabilized by tendons.
The blades of the human pelvis are not rotated inward like those of the chimpanzee.
Answer:
B. The human foot has three arches, but the chimpanzee foot only has one.
Explanation:
On edge finished the quiz
The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.
What is the difference between humans and chimpanzees?Humans have a significantly more developed brain, better motor control, and less body hair. The human brain's neural network has been found to be much more complex, and spindle neurons have also been discovered.
Nucleotide-for-nucleotide was discovered to differ from the human genome with which it was compared by roughly 1.23 percent. This equates to roughly 40 million changes in our DNA, with half most likely the result of mutations in the human ancestral line and the other half occurring in the chimpanzee line since the two species split.
The human foot has three arches, but the chimpanzee foot only has one. Therefore, option B is correct.

Sewage sludge (biosolids) removed from a municipal wastewater treatment plant is a mixture of organic material and water. Research and explain why the incineration of sewage sludge may require more energy than it produces. Explain why people may be reluctant to use biosolids as a fertilizer for food crops.
Hey love! <3
Answer:
Sewage systems are used all around the world transferring waste to treatment plants where they are filtered and traded in for organic material. If the sluge were to be incinerated it could be repurposed, however the gas used to burn the sewage waste comes from condensing saturated fuel oil and requires 195 SCM of natural gas to successfully complete the chemical transfer. That's a lot of energy, and the natural process costs plenty more then what you're getting in returns. Through the process toxins can develop inside of the incinerated waste which could poison crops and animals, studies also show the process can release carbon monoxide into the air. To conclude it's called sewage waste for a reason, what goes down should stay down instead of putting what we eat and inhale at stake.
Hope this helps out! (ﾟヮﾟ) Sincerely, Kelsey from Brainly.

The incineration of sewage sludge may require more energy than it produces because of the high cost of energy.
Municipal wastewater treatment plants are estimated to consume more terawatt hours per year of electricity, which equates to about billions in annual electric costs. That's a lot of energy, and the results show that wastewater sludge able to produced up to 44.82 ml biogas/kg of sludgePeople may be reluctant to use bio solids as a fertilizer for food crops.
because:-
One health risk with the land application of bio solids is the potential exposure to pathogens (disease causing organisms)One of the risk is that the bio solids may contain chemicals that are directly toxic in small concentrations or doses.What is sewage sludge?Sewage sludge is a product of wastewater treatment.
