Four students provide their teacher with an explanation of why photosynthesis is considered a chemical change. Luke: Photosynthesis is considered a chemical change because the CO2 molecules disappear and the O2 molecules reappear. Jackie: I know that photosynthesis is a chemical change because all of the reactants undergo a state of matter change and are all present as a product. Tara: Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change. Skyler: Photosynthesis is a chemical change because solar energy is required. Which student provides the best explanation of why photosynthesis is a chemical change
Answer:
The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".
Explanation:
A chemical change is one which is not easily reversible and which results in the formation of new subsatances.
For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.
From explanations provided by the students :
Luke does not give any explanation of the process but only an observation
Jackie's explanation does not state the main reason why a chemical change differs from a physical one.
Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.
Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.

How many chromosomes would you expect to be in the daughter cells of the mosquito after meiosis? When starting with 6
Answer:
The correct answer would be - three chromosomes.
Explanation:
Meiosis is the type of cell division that takes place in only sex cells and called reduction division as a single parent cell divide into four daughter cell that contains a half number of chromosomes as the parent cell.
The daughter cells are always haploid and have the half number of chromosomes. If an organism has 2n number of in its parent sex cell the daughter cells after meiosis will have n number of chromosomes
Therefore, mosquito = 2n = 6
after meiosis = n = 6/2 = 3
Thus, the correct answer would be - 3 chromosomes.
4. Analyze: Compare the offspring traits to the parent traits.
A. Which traits were passed from parents to offspring? __________________________
B. Which traits were not passed down? ______________________________________
Traits that are not passed down (not inherited) are called acquired traits.
Answer: 4a. The transmission of characteristics from parents to offspring is called heredity, and the characteristics that are inherited can be predicted. 4b. An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics.

Explain the terms “criteria” and “constraints.” Criteria are things the design needs to do in order to be successful--its requirements. Constraints are limitations on the design. These may be materials available, the cost of the materials, the amount of time they have to develop the solution, etc.
Design criteria are the explicit goals that a project must achieve in order to be successful. ... Design criteria can be divided into primary and secondary criteria. Primary criteria are those that constitute a successful project; the project will be unsuccessful if it does not meet these goals.
Explain why finding the average energy of the system would be a smarter way to record the temperature than giving the energy of each individual particle
Answer:
See Explanation
Explanation:
Temperature is defined as the average kinetic energy of the particles of a system.
In a system, there are several particles moving at various velocities and having various values of kinetic energy. It is very difficult to determine the individual kinetic energies of each individual particle.
Hence, we only need to obtain the average kinetic energy of the particles of the system in order to record the temperature.
Explain why you you think the population of each organism changed the way it did
Answer:
If populations don't change very much over time, the ecosystem is in equilibrium .Populations decrease at higher levels of the food chain because they require more energy from other organisms.
The given question is seems it lacks some information, however, on the best knowledge of the provided information the correct answer would:
The change in the population of each organism is due to the evolution process that takes place because of changes in the environment in order to survive.
The changes in the genetic material of a particular population occur over a long period of time, the cause of this change is the process called evolution.
Evolution exhibits the adaptations that took place in organisms to their environmental changes that lead to altered genes, novel characteristics, and new species.changes in genetic variability and changes in allele frequencies over timenatural selection is the cause of evolution that occurs in organisms that are more likely to survive and reproducerandom fluctuations in allele frequencies in a population called genetic driftThus, the correct answer is - evolution.

Answer:
D.Predation
Explanation:
Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.
Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.
The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.
