Answer: b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.
Answer:
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment.
Explanation:
Chimpanzee for the first one
The correct answer should be B. Small regions interspersed with other biomes. This type of a biome is found on all continents and in many countries. It's specific because it's similar to a desert when it comes to yearly precipitation, but it is different insofar that it has a lot of plants and animals that are mostly nocturnal predators.
Incomplete question. The remaining part of the question read;
Put the processes in order to describe the interaction between these two systems.
- Then Blood is pumped through the circulatory system to deliver nutrients to other organs.
- Digestive processes break nutrients down in the mouth, stomach, and small intestine.
- Nutrients are ingested at the mouth. Nutrients enter the capillaries of the circulatory system.
- Nutrients diffuse through the villi of the small intestine.
<u>Explanation:</u>
<u><em>The correct order of processes:</em></u>
- Nutrients are ingested at the mouth.
- Digestive processes break nutrients down in the mouth, stomach, and small intestine.
- Nutrients diffuse through the villi of the small intestine.
- Nutrients enter the capillaries of the circulatory system.
- Then, Blood is pumped through the circulatory system to deliver nutrients to other organs.
So, the first sequence begins when nutrients from the food we eat enter the mouth. Our digestive system begins to work as we chew the food using our teeth. When the food is swallowed into the stomach the digestive process continues until nutrients contained in the food are then diffused or absorbed by the Villi; a part of our small intestine, to be used by other body organs. Then, Blood is pumped through the circulatory system to deliver nutrients to other organs.
