Answer:
I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.
Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.
Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that). You have big toes because they used to be useful thumbs for your grasping feet.
Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.

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.

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 ..

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?

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.

A
Explanation:
I hope this helps :)
Answer:
1 - D
2 - B
3 - A
4 - A
Explanation:
Hello There!
D=Distance
T=Time
S=Speed
For the first one we are given the speed and the time and we need to find the distance
To do so we multiply the two together( the two meaning the speed and the time)
They run 20 m per second and
if they run for 40 second
(20*40=800)
they will run for a total of 800m therefore the answer to the first one is D
for the second one we are given the distance and the time and we need to find the speed.
Looking at the formula chart we can find the speed by dividing the distance over the time
so speed = 80/5
80/5=16 so the speed is 16m/s (B)
For the third one we are given the distance and the time and we need to find the speed
Once again we can find the speed by dividing the distance over time
20/5=4 so the bunny hops 4m/s
For the last one we are given the speed and the distance and we need to find the time it took to get to the associated distance
another way we can find the time is by dividing the given speed by the distance
so time = 1500/250
1500/250=6 so it will take the space ship 6 seconds to reach a distance of 1500m
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.

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.
This process occurs when the cell uses energy to bring something in from outside the cell.
