Which equation best represents conservation of matter?
3H2O + 3CO2 → C6H12O6 + 6O2
6H2O + 10CO2 → C6H12O6 + 4O2
6H2O + 6CO2 → C6H12O6 + 6O2***
6H2O + 6CO2 → C3H6O3 + 3O2
A large portion of cellular respiration happens in the mitochondria. For this reason, the mitochondria are known colloquially as the “powerhouses of the cell.” Which body organ could best be compared to the mitochondria?
the stomach because it breaks down nutrients and creates energy for the body***
the lungs because they add oxygen to the body
the heart because it pumps nutrients around the body
the brain because it controls the body
Why does a diet high in sugar lead to weight gain?
Sugar is a lipid, which is stored as fat in the body.
Sugary food causes blood sugar levels to spike, telling the body to retain weight.
Fat is a carbohydrate, which leads to weight gain.
Sugar and fat are made of the same elements, so sugar can be converted to fat.***
What makes amino acids unique from one another?
the long strands of glucose molecules
the carboxyl group
the R group***
the amino group
What are reactants in a chemical reaction?
substances that are formed by reactions
outputs
substances that speed up reactions
inputs***
Reliability refers to
professionalism.
expertise.
consistency.***
relevancy.
During a chemical reaction, the quantity of products
increases.***
decreases.
stays the same.
fluctuates.
Everything was right for me except the last one "During a chemical reaction, the quantity of products" stays the same and doesn't increase.
All correct, 100% :)
Your friend asks for your help checking their essay about sugar production and use in plants. They have found an online encyclopedia stating that plants produce glucose via photosynthesis. Glucose is linked together to form the carbohydrate starch. They are confused, though, because a university website states that glucose is linked together to form cellulose, the main part of plant cell walls.
In 3–5 sentences, describe how you can help your friend check their information and how both statements can be true.
Starch is made up of long chains of glucose. While cell walls are made from cellulose created from photosynthesis. Cellulose is made up of glucose and cell walls are the most abundant carbohydrate.
(re-phrase pls) :)
The phrase "you are what you eat" is factually correct because when the body breaks down the food matter being consumed, the elements and molecules that form will be used by the body. These will be used to create new biomolecules that will be used for growth and repair. Without a healthy diet the body wont have these, effecting ur over all heath.
I can confirm all of these are correct!!! Thank you sooooooooooooo much!
Answer:
endothermic reaction
Explanation:
This is because it absorb heat from the surrounding which is required to break the bond hold it together hence as it absorb heat from the surrounding the temp of surrounding decrease.
