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?
Claim: Individuals in a population have genetic variations that can be passed on to their offspring. How could an organism's traits influence the survival rate of the population?
Answer:
If an animal has a certain trait that decreases it's fitness ( i.e. less likely to survive), it can lower the survival rate of that population. Verses a population with a trait that increases fitness ( i.e. More likely to survive) and would most likely increase the survival rate.

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.

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.
PLEASE HELP - While walking in the woods one day,you come across A strange object. You decided to investigate the object to determine if it's a living organism or not.Explain the characteristics you would look for to determine if the object you found is a living organism.
1. Using the grid provided, label the x-axis “Year". Label the x-axis with the years listed in picture one below.
2. Based on the sizes of the numbers for each population, create a scale on the two separate y-axes (similar to the snowshoe hare-lynx graph). Place the moose population on the y-axis on the left side of the x-axis and the wolf population on the y-axis on the right side of the x-axis.
3. Construct a line graph using the data from Table 2. Use a different coloured line for each population.
4.Give your graph a title. Create a legend for your graph so it is easy to read.
after your done with graph please answer this questions!
1. Describe the relationship between the moose and wolf populations.
2. What biotic and abiotic factors might influence the moose and wolf populations?
3.How would the carrying capacity for wolves be influenced if a large number of moose were killed by humans?
also please make sure the grid your using is the same as in picture two below!
Answer:
Here is the graph
Explanation:
Working on answering questions
Answer:
the moose and wolf population is increasing on 1960 and 1965.moose population is increasing but wolf population decreases on 1970.both are increasing on 1975 and 1980.moose population decrease but wolf population increases on 1985.wolf population decrease but moose population increases on 1990 and 1995.moose population decrease but wolf population increases on 2000 and on 2005.Explanation:
2.yes, biotic and abiotic factors might influence the moose and wolf populations.if there is more population of wolf ,moose population will be less
3. the carrying capacity for wolves be influenced if a large number of moose were killed by humans is that the number of wolf automatically decrease when a large number of moose were killed.as wolf is totally depend on moose.
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.

What is a natural way to control an aphid population?
release ladybugs into habitat
praying mantis
insecticide
Answer:
I would say that the answer is A, or releasing ladybugs into a habitat.
Explanation:
This is the only "natural" way to control an aphid population. However, please note that as well as ladybugs, praying mantis's also eat aphids. But, the answer choice doesn't describe the option very well, so that is why I say that it is A.
Hope it helps!
The natural way to control an aphid population is release ladybugs into habitat. The correct option is 1.
What is Ladybug?Ladybugs are natural aphid predators that can consume large numbers of them, assisting in population control without the use of harmful chemicals.
A natural way to control an aphid population is to release ladybugs into the aphid's habitat.
Although praying mantises are natural predators of aphids, they are less effective at controlling their population than ladybugs.
Insecticides, on the other hand, are chemical treatments that can be harmful to both beneficial insects and the environment.
As a result, using insecticides to control aphid populations is not a preferred method, particularly in natural or organic settings.
Thus, the correct option is 1.
