Answer:
Echinoderms evolved from animals with bilateral symmetry. Although adult echinoderms possess pentaradial, or five-sided, symmetry, echinoderm larvae are ciliated, free-swimming organisms that organize in bilateral symmetry which makes them look like embryonic chordates.

You're in a town called Watertown. You need to save it from water pollution. They don't have any money! SO, they need you to use stuff from your house (imagine). Make a design that shows how to stop it from happening. How could you clean the water in your model using the materials around the house?
PLEASE HELP ME! I NEED HELP!! IF YOU GOT ONE, MAKE A QUESTION AND ILL GIVE YOU ALL MY POINTS.
Answer: You can clean the water pollution by the water bottle activity.
Explanation:
You can do the water bottle filteration. From your house, you should find a large soda bottle or water bottle. YOu layer it with sand and gravel at the bottom. Line the top of the bottle with a coffee filter. This will allow for a natural filtration system.
You can find this on many science experiments websites because it is a common science fair project.
Search tool would be: homemade water filter

What is happening when the angle of the sun hitting the planet during our winter solstice when is that?
WILL BE MARKED BRAINLIEST!
Answer:The summer solstice occurs at the moment the earth's tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice. The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China. For every place north of the Tropic of Cancer, the sun is at its highest point in the sky and this is the longest day of the year.
The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.

(Write a brief summary for people who aren’t familiar with the science of bringing back extinct species). This section should be at least one paragraph which includes information on how cloning works (in your own words), the opinion you stated in step one (we should try to bring back extinct animals) and your supporting evidence.
Answer:
Earth is in the midst of its sixth mass extinction: Somewhere between 30 and 159 species disappear every day, thanks largely to humans, and more than 300 types of mammals, birds, reptiles, and amphibians have vanished since 1500. These rates do not bode well for the future of life on our planet, but what if extinction wasn’t permanent? What if we could resurrect some of the species we’ve lost?
For decades the notion of “de-extinction” hovered on the scientific fringes, but new advances in genetic engineering, especially the CRISPR-Cas9 revolution, have researchers believing that it’s time to start thinking seriously about which animals we might be able to bring back, and which ones would do the most good for the ecosystems they left behind.
Please help me :/ im not smart
Answer:
Well I'm not smart either. But i'll give you the answer.
Explanation:
Since the population of gray squirrels and brown squirrels decreased, and the population of black squirrels increased, that means the gray and brown squirrels were eaten/left and didn't blend in very well to their habitat. However, the population of black squirrels increased, so they blended in well with their environment. This tells us that the color of the trees became darker, closer to black, since there were more of them.
Answer: in explanation
Explanation:
Over time the color of the trees changed to black or a dark color. Because the color of the trees changed the gray and brown squirrels were more noticeable to the foxes causing them to be killed off. This meant over time the squirrells with black fur survived and bred eventually populating the area with black squirrells.
1. Adult blank reproduce sexually by releasing sperm and egg.
2. The egg develops into a blank.
3. The blank attaches to a hard surface and develops into a polyp.
4. Parts of the polyp may break away. This is a form of blank reproduction
5. Each polyp matures into an adult, called a blank.

Does the plant cell or animal cell have a larger vacuole?
Answer:
Plant cell
Explanation:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright.

Can organisms grow in environments that do not meet their needs?
(Please be legit about the answer thank you)
Answer:
In most cases, no.
Explanation:
Some basic needs of an organism are an appropriate environment ( E.g. Having water for fishes, be it salty or fresh), have a reasonable temperature and pH value of its surroundings, and having enough food to sustain itself. You can even look at things like air composition.
There's no way an organism that normally lives in slightly alkaline water can survive in water with a pH of 3. Similarly, organisms can't survive in unsuitable temperatures, like how a polar bear can't survive in the desert.
In cases like food, they would die from starvation without appropriate amounts of food.
In essence, an organism is not likely to be able to grow in environments that do not meet their needs.
Some organisms adapt and change over time depending on the organisms, but most of them may die before adulthood.
