What do these two changes have in common?
saliva breaking down a piece of bread
a penny tarnishing
Select all that apply.
both are caused by heating
both are chemical changes
both conserve mass
both are changes of state
Answer: both are changes of state and both are changes of state
Explanation:
.
The two changes like the Saliva breaking down a piece of bread and a penny tarnishing involves chemical change. Thus, the correct option for this question is B.
What do you mean by Chemical change?A Chemical change may be defined as a type of change that significantly involves the production of new substances from old ones by combining each other with different properties.
The action of saliva is stimulated by the action of the enzyme salivary amylase which hydrolyzed the starch into maltose, a disaccharide. A penny tarnishing involves the dissolution of copper oxide in a mixture of weak acid and table salt.
Therefore, the given two changes have in common that both are chemical changes. Thus, the correct option for this question is B.

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.

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 does NASA expect to gain by studying the effects of long-term space travel on the human body?
Answer:
NASA studied astronaut twins Mark & Scott Kelly to determine the effects of staying in space for a year. ... Space presents unique stresses to the human body. With lower gravity levels, for example, bones and muscles are more likely to become weak since they no longer have to support the weight of the body.
