Why does the moon appear to change its shape as seen from earth?

Answers

D.
Different parts of the sun lit moon become visible as the moon revolves around earth

This happens because as the moon orbits earth the sun will project light towards it and the reason it seems to glow is because of the reflected light since the moon is white it reflects more light. Think of it as a day and night cycle except it’s on the moon when it becomes night on earth the part of earth facing towards the sun will be lit aka day/morning/afternoon etc
The part of the earth facing away will be dark aka night/midnight/etc.
D because as the moon revokes it goes around earth to every state and it takes 12 hours in our time for it to get to us.

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.

Answers

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

Rain catcher: paper towel, water jug, and water, strainer, and box use paint for decoration

If you add up all parts of a system then divide by how many parts you are finding the of the system.*

Please help me :/ im not smart

Answers

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.

how are traits passed down from one generation to another

Answers

Answer:

Genes & DNA

Explanation:

Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.

Answer:

Traits are passed down from one generation to another because of DNA.

Explanation:

Genetic inheritance occurs due to genetic material, in the form of DNA, being passed from parents to their offspring. When organisms reproduce, all the information for growth, survival, and reproduction for the next generation is found in the DNA passed down from the parent generation.

I think that cell types look the way they do because they are all very unique. They don’t have much space to look a certain way but they are all unique in their own ways. The structure of a cell does have something to do with it’s function, it has to be small to do it’s work.

(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.

Answers

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.

What are the functions of vitamins and minerals?

Vitamins and minerals help us fight infections, heal wounds, build strong bones, and regulate hormones, among other bodily functions. Nutrients and minerals can cause harmfulness whenever consumed in enormous sums.

Vitamins and minerals are essential for healthy growth and development in children. A variety of foods from each of the five food groups can provide vitamins and minerals to children.

In contrast to other dietary components known as macronutrients (such as fats, carbohydrates, and proteins), which are the compounds utilized in the reactions regulated by the vitamins, the vitamins regulate reactions that occur in metabolism.

Can organisms grow in environments that do not meet their needs?

(Please be legit about the answer thank you)

Answers

Yes organism can grow in environments that do not meet their needs but it would be very hard for them to stay alive in that environment since it doesn’t have all the requirements the organism needs to survive.

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.
