How does the section “Many Chemical And Physical Changes Are Happening In Nature” relate to section “Matter Isn't Lost In Photosynthesis”
This chemical change conserves matter. These plants are eaten by animals within and near the stream. Their bodies use the chemical energy stored in their bodies to power their cells and move around.
What is law of mass conservation?The law of conservation of mass usually implies that mass can never be created nor destroyed in a chemical reaction.
When coal is ignited, for instance, the carbon atom transforms into carbon dioxide. The carbon atom changes from a solid to a gas, but its mass remains constant.
According to the law of conservation of mass, mass in an isolated system is neither generated or destroyed by chemical or physical transformations.
The mass of the products in a chemical reaction must equal the mass of the reactants, according to the law of conservation of mass.
The two sentences, i.e., “Many Chemical And Physical Changes Are Happening In Nature” relate to section “Matter Isn't Lost In Photosynthesis” as during photosynthesis, mass is conserved but there are many physical and chemical transformations during the process.
Thus, this way these two statements relate to each other.

3. The radula and crystalline style of molluscs are part of the:
A) reproductive system
B) defensive mechanisms
C) excretory system
D) nervous system
E) digestive system
Answer:
E. digestive system
Explanation:
Mollusks/Molluscs are invertebrates of the Kingdom Animalia. It is said to have the biggest population when it comes to the marine phylum.
It has an organ called the "radula" that is responsible for grinding food. This organ looks like a tongue. Its "crystalline style" is located in the middle part of its gut. It is responsible for secreting enzymes and it helps in extracellular digestions.
Clearly, the radula and crystalline style are both part of the mollusc's digestive system.
The excretory system helps the respiratory system by
O introducing more oxygen into the lungs.
O circulating blood into and out of the lungs.
O removing carbon dioxide that is produced during respiration.
O removing urine that is produced during respiration in
Answer:
The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).
Explanation:
The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.
As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.
The other options are not correct because:
The excretory system does not introduce more oxygen into the lungs. The circulation of blood in and out of the lungs is a function of the circulatory system. Urine is not produced by breathing.Answer:
The answer is C
Explanation:
What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2
Answer:
The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.
Explanation:
The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.
The process of cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions where, from a glucose molecule, energy is obtained in the form of ATP molecules.
Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:
C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂
This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.
For the other options it is important to mention that:
C₆H₁₂O₆ is the substrate from which cellular respiration takes place. ATP is the final product of cellular respiration, translated into energy to be used by the cell.Answer: The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

centrioles
mitochondria
golgi body
endoplasmic reticulum
Answer:
Endoplasmic reticulum
Explanation:
The endoplasmic reticulum is part of the endomembrane system inside almost all eukaryotic cells.
The membrane is continuous with the nuclear membrane. The endoplasmic reticulum is very important for modifying proteins and transporting them in vesicles to the Golgi body for further processing and transport to their final destinations.
The endoplasmic reticulum can be rough (have ribosomes attached) or smooth (lack ribosomes).
What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa's body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?
The missing part of the question is as follows:
Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
Answer:
1. The food she ate is peanut butter and bread, the peanut is rich in protein while the bread is rich in carbohydrate which provides sugar (glucose) by breathing she gets oxygen in a sufficient amount to perform cellular respiration (aerobic) to carry out energy for running. Carbohydrates are a better choice of nutrients befors exercise as carbohydrates provide energy immediately.
Aerobic respiration provides a high amount of energy, 36 ATP to be specific, per cycle of cellular respiration.
2. The carbohydrates (glucose) and oxygen she gets from food and breathing react together to perform aerobic cellular respiration to carry out maximum energy. By the digestive system and organs of this system, carbohydrates are broken down into glucose which is diffused into the blood.
Oxygen also diffused to blood from the lungs and heart with the help of the respiratory and cardiovascular systems of her body.
3. By the aerobic cellular respiration process takes place in the mitochondria of the cell helps in providing energy from glucose and oxygen by a three-step process:
Glycolysis, the Krebs cycle, and oxidative phosphorylation. Here glucose reacts with oxygen. Which ultimately provide 36 ATP molecules for the cell in a run.

Explanation:
Exocrine pancreatic insufficiency (EPI) is a condition characterized by lack of the exocrine pancreatic enzymes, resulting in the failure to digest food properly (especially fats). A healthy diet is important for everyone, but especially for people with EPI. One treatment called pancreatic enzyme replacement therapy, or PERT, replaces the digestive enzyme that your pancreas isn’t producing anymore. What function does PERT replace?
A. It serves as a reactant and is consumed in the reaction.
B. It serves as a product and lowers the activation energy.
C. It serves as a biological catalyst and lowers the activation energy.
D. It serves as a waste product and raises the activation energy.
Answer:
Pancreatic enzyme replacement therapy (PERT) serves as a biological catalyst and lowers the activation energy.
Explanation:
Enzymes act as biological catalysts that allow a reaction to occur faster and with less activation energy. An enzyme replacement therapy, such as PERT used in the case of exocrine pancreatic insufficiency, is able to supply the function of an enzyme that the body does not produce.
The exocrine pancreas produces digestive enzymes, such as amylase and lipase, which aid in the digestion of carbohydrates and lipids. In the absence of enzyme production by the pancreas, PERT provides the necessary enzymes for digestion.

The arrows in the model should point in the opposite directions to show ADP releasing its energy to form ATP
“ATP” and “ADP” should switch positions because ATP is a high energy molecule and ADP is a low energy molecule.
“Energy from Food/Light/etc.” should be going out of the cycle rather than into the cycle. Energy from food breaks down ADP into ATP.
“Energy used for cellular work” should be going into the cycle rather than out of the cycle. Energy for cellular work breaks down ADP into ATP.
