How will you know if a chemical change has occurred when the reactants are combined? Use evidence and scientific reasoning to support your answer.
Answer:
I would know if a chemical change is occurred if a new material is formed which doesn't share any characteristics of the reactants example if we expose iron to water and air a new material is formed (rust) which doesn't share any characteristics of iron,water or air.
Heat Transfer Lab
The following represents a lab set up for heat transfer. The cup on the left started with boiling water at 100 degrees C and the cup on the right has water at 20 degrees C. There is an aluminum bar between the two cups allowing heat to transfer from one cup into the other. The set up will be left alone for 20 minutes and temperatures of each cup of water will be recorded every minute for 20 minutes.

Which example shows an interaction between the urinary system and the circulatory system?
A. a break in a bone
B. the inhalation of air
C. a bee stinging the skin D. the blood flowing to the kidneys
The blood flowing to the kidneys is an example of interaction between urinary and circulatory system.
What is circulatory system?Circulatory system is a system which consists of heart, blood vessels and blood which is circulated throughout the entire human body. It also includes the cardiovascular system or the vascular system comprising of the heart and blood vessels.
The circulatory system has two divisions :1) systemic circulation 2) pulmonary circulation. The network of blood vessels are large elastic arteries and large veins.Blood is a fluid which consists of plasma ,red blood cells ,white blood cells and platelets which are circulated around the body.
This way oxygen and nutrients are circulated to the tissues. The circulated nutrients include proteins and minerals and gases such as oxygen ,carbon dioxide hormones and hemoglobin which provides nourishment.
It also helps the immune system to fight against diseases and maintain homeostasis by maintaining temperature and pH.

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

What three things happen to plates at the plate boundaries (where two or more plates come together)?
a. _______________________________ at spreading ridges.
b. _______________________________ at convergent margins.
c. _______________________________ at transform faults.
Plates are thin at spreading ridges, plates sink at convergent margins, and plates slide past one another at transform faults. Plate boundaries are borders where two tectonic plates interact with each other.
What are plate boundaries?Plate boundaries can be defined as the borders where two tectonic plates meet and interact with each other.
Geologic activity (e.g., volcanic activity) always occurs at the plate boundaries.
Convergent plate boundaries refer to the place where plates are moving towards one another.
Transform plate boundaries refer to boundaries where the motion is predominantly horizontal.
