Answer:
Water changing from a liquid to a gas (steam)
Explanation:
When water changes states of matter it is considered a physical change. Not a chemical one.
Water changing from liquid to steam is not a chemical reaction.
What is chemical reactions?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products. An arrow is drawn between the reactants and products to indicate the direction of the chemical reaction, though a chemical reaction is not always a "one-way street," as we'll explore further in the next section.
According to the question
1> Water changing from liquid to steam
Boiling of water to form steam is a physical change because during this only change of state occurs from liquid water to steam (gaseous) without any change in its chemical composition or there is no new bonds are formed or broken .
2> Apple turning brown from oxygen hitting it
Apples turn brown because of a chemical reaction called "oxidation", which is caused by oxygen from the air.
3> Baking soda and vinegar creating bubbles
Mixing baking soda and vinegar will create a chemical reaction because one is an acid and the other a base
4> Cellular respiration creating energy
The degradation of foodstuffs is to convert the energy contained in chemical bonds into the energy-rich compound adenosine triphosphate (ATP), which captures the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
Hence, the Water changing from liquid to steam is not a chemical reaction.

How does the coriolis effect cause global winds to move in the Northern and Southern hemisphere?
Answer:
But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect.

Your friend has researched the biological classification of an organism. However, he mistakenly scrambled the order of the different classification groups. In addition, he cannot remember the common name of the organism. Your friend needs your assistance. The list below shows his notes. Reorganize the information in the correct order, beginning with the largest classification group and ending with the smallest. Use clues in the scientific names to predict the identity of the organism. Then conduct research to see whether your prediction is correct. Notes on Unknown Organism 1. Order Falconiformes 2. Genus Haliaeetus 3. Class Aves 4. Species leucocephalus 5. Domain Eukarya 6. Phylum Chordata 7. Family Accipitridae 8. Kingdom Animalia

since i'm so du/mb, and forgot what newtons 2nd law was can someone explain?
Answer:
It's the equation f=m · a or, force equals mass of an object times acceleration.
Explanation:
you are far more smarter than you think.
Newton's second law states that the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

A cymothoid isopod lives inside the mouth of a snapper fish. The isopod servers blood vessels in the fish's tongue, causing the tongue to atrophy and degenerate. The isopod then hooks its pereopods, or legs, to the base of the fish's tongue, essentially replacing the tongue. The isopod stays there for the rest of its life, feeding on blood, mucus, and stray pieces of food from the fish.

Glaciers are formed by snow falling from the atmosphere on a place such as Alaska, where it does not melt. More and more snow falls and becomes compacted over a period of time to make a glacier. A glacier that moves seven miles per year is considered a very rapidly-moving glacier. Different parts of a glacier may move along at different rates of speed.
How do Earth’s spheres interact when a glacier moves across its surface? Name three spheres and give examples of interactions.

okay so i have two questions theres no right or wrong answers just give me ur opinion and why you feel that way pls ..
Opinionated question 1. Many plants like soy bean and corn have been selectively bred. Do you think this is acceptable?? why or why not???
Opinionated question 2. Do you think humans should have selectively bred dogs? Why or why not?
Thanks.
Answer:
1. No, because by selectively breeding the plants you are causing the population to be very similar and could possibly not allow the plants to benefit at all times from environmental factors that could cause them health risks.
2. No, because by not selective breeding dogs we allowed for their to be a larger population of different dogs which allows some to be good at a specific thing and others not to be. This allows variety and genetic diversity allowing us to choose which dog we want/need for different things like work or just to have.
