[Sagot para sa’yo] The results section of a scientific investigation should include:a.The aim or problem being investigated b.A list of the materials and equipment usedc.Detailed data and observations collected d.The conclusions drawn from the investigation ​

[Sagot para sa’yo] Decantation is a technique used in separating a less-dense substancefrom a dense one. In the process of decantation, the mixture is leftundisturbed. When the components are separated, the less dense substancecould be removed by scooping using a spoon or it can be removed by slowlypouring out the less-dense substance. Oil in water could be removed usingthe decantation technique. The fats that float in your sinigang could beremoved by decantation or scooping.Some of the mixtures that can be separated by decantation are thefollowing:A. oil in waterB. Gasoline in waterC. Sinigang with floating fatsD. Mud and water​

If Glossopteris fossils were found in Antarctica, what was the climate ofthis continent before?Q3. If the climate and the position of a place were relative to each other, wherethen was the initial location of Antarctica 250 million years ago?Q4. Is the presence of animal fossils tells that South America, Africa, andAntarctica were once connected?​

[Sagot para sa’yo] DIRECTIONS: Answer the following questions. 1. How do heavier elements formed during stellar nucleosynthesis? Explain your answer using the concept map below. Answer: Heavier elements are formed through a series of nuclear fusion reactions that occur within stars. The concept map illustrates the main stages: - Stellar fusion or nucleosynthesis: This process happens in the core of stars, where the intense heat and pressure allow for atomic nuclei to fuse together.- Main-sequence stars: These are stars in their stable phase, primarily fusing hydrogen into helium through the proton-proton chain reaction and the CNO cycle.- Red giant stars/supergiant stars: As stars evolve, they become red giants or supergiants, expanding and fusing helium into heavier elements like carbon and oxygen through the triple-alpha process and the alpha ladder.- Supernova explosions: When massive stars reach the end of their lives, they explode as supernovae, releasing tremendous energy that allows for the formation of even heavier elements through the r-process. 2. What can you notice on the number of the atomic number patterns of the elements in alpha ladder being shown below. Discuss your findings. Answer: The alpha ladder reactions show a pattern of adding 4 to the atomic number of the element with each step. This is because each step involves the fusion of a helium nucleus (alpha particle), which has an atomic number of 2, with the previous element. - ¹²C + ⁴He → ¹⁶O (Atomic number increases from 6 to 8)- ¹⁶O + ⁴He → ²⁰Ne (Atomic number increases from 8 to 10)- ²⁰Ne + ⁴He → ²⁴Mg (Atomic number increases from 10 to 12)- ²⁴Mg + ⁴He → ²⁸Si (Atomic number increases from 12 to 14)- ²⁸Si + ⁴He → ³²S (Atomic number increases from 14 to 16) This pattern is a key characteristic of the alpha ladder process. Let me know if you have any other questions!​
