Organisms obtain energy by breaking down food during a chemical reaction. Which substance reacts with the food in the chemical reaction?
A. carbon dioxide
B. chlorophyll
C. oxygen
D. water
Answer: carbon dioxide
Explanation:
Plants, unlike animals, can make their own food. They do this using a process called photosynthesis.
During photosynthesis, plants produce glucose from simple inorganic molecules – carbon dioxide and water – using light energy.
Answer:
For sure not Carbon Dioxide...

What 2 vocabulary words depend on each other, or "go hand in hand"?
A. Feature & Variation
B. Trait & Function
C. Structure & and Function
D. Structure & Protein Molecule
Answer:
C. Structure and Function
Explanation:
The reason as to why it is C is because, Structure means construct or arrange according to a plan; give a pattern or organization to, to put it more simple, the way something is built to help the way it functions. So for example, the structure of a hair brush is built to pull out the tangles, why would I use it on feet? It's not structured the way it will help function my feet. Function means, work or operate in a proper or particular way. Example: "bridges perform the function of providing access across water" Basketball shoes are "STRUCTURED" in a way it'll help the basketball player play better. You wouldn't wear boots to a basketball game because boots are structured in order to help the human feet get through the snow. Basketball shoes are structured in order to help it function so that the basketball player can move around freely on the court and play freely.

Organisms are classified according to shared characteristics. This process has led to the development of a classification system that has various levels of organization. Which of the following levels of classification is of the lowest hierarchy?
A. domain
B. class
C. family
D. species
Species levels of classification are of the lowest taxonomic hierarchy, hence option D is correct.
What is the lowest taxonomic hierarchy?The categorization of living things is the main objective of the biological field of taxonomy. Taxonomy is the formal categorization of organisms into groups based on those postulated links.
Eight levels of taxa make up the generally used categorization scheme, which is based on the Linnean system. They are, from most general to most particular, domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.
On earth, there are around 8.7 million distinct species. It describes a collection of organisms with comparable form, morphology, and reproductive characteristics.
Therefore, organisms are classified according to shared characteristics, species is the lowest taxonomic hierarchy.

Explanation:
The body absorbs nutrients through the small intestines. The blood transports these nutrients to every cell in the body. The blood also carries oxygen to every cell. The cells use the nutrients and oxygen to supply the energy the body needs. What three body-systems are working together in this situation?
A. nervous, digestive, and circulatory systems
B. digestive, circulatory, and excretory systems
C. respiratory, circulatory, and digestive systems
D. circulatory, immune, and respiratory systems
Answer:
(C) Respiratory, circulatory, and digestive systems
Explanation:
In this example, the respiratory system is being used because oxygen specifically is being transported through the bloodstream to the body. The way that oxygen enters the body and is stored until the blood can pick it up is of course through breathing! Another word for breathing is respiration and this involves the lungs, which all points to the respiratory system.
The circulatory system is being used due to the fact that blood specifically is being used to transport these nutrients and oxygen around the body. Blood passes through veins and arteries through the body and is all a part of the circulatory system!
Lasty, the digestive system is being used because the small intestines are absorbing nutrients and the intestines are where a majority of digestion takes place (hence, the digestive system).
Answering questions like these, or any question about body systems, means you need to know about what each system is and what it does. It can help to think about what body parts each system includes and one or two key words involved with that system. Ex. CIRCULATORY: blood. CARDIOVASCULAR: heart, capillaries, veins, arteries, pumping blood
In the given situation, the respiratory, circulatory and digestive systems are working together.
Working of the body systems:In the given case, as oxygen is mediated through the bloodstream in the body, therefore, respiratory system is being used. The blood is being used to mediate oxygen and nutrients all through the body, therefore, circulatory system is being used.
Blood is moved via arteries and veins throughout the body, which is a component of circulatory system. In the given case, as the small intestines are used to absorb nutrients, and it is the place where maximum of the digestion process takes place, therefore, digestive system is also taking part in the process.
Thus, the correct answer is option C.
