Explanation;

-A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A hypothesis is a tentative, testable answer to a scientific question.

-A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e, it can be tested by another individual through an experiment or measurement), leads to a hypothesis that is falsifiable (i.e. it should generate a hypothesis that can be shown to fail), etc.

Which statement is true? Lipids are a type of fat. Fats are a type of lipid. Fats and lipids are separate and unrelated substances. All lipids are fats, and all fats are lipids.

Answers

The correct answer is the second option: Fats are a type of lipid. The first option is incorrect, because lipids are the larger, overarching group that fats fall under. The third option is incorrect because fats and lipids are completely related, as displayed by the correct answer. Fats are a specific type of lipid. The last option is incorrect. Although all fats are lipids, all lipids are not fats. Lipids also comprise waxes, phospholipids, sterols, etc.

Final answer:

Among the provided options, the accurate statement is 'Fats are a type of lipid'. Lipids encompass a wider class of molecules which includes fats among others. Therefore, while all fats are lipids, not all lipids are fats.

Explanation:

The correct statement among the options is, 'Fats are a type of lipid'. Lipids are a broad group of naturally occurring molecules which include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, triglycerides, phospholipids, and others. The main biological functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Fats, on the other hand, are a subclass of lipids, known as triglycerides. So, not all lipids are fats, but all fats are lipids.

which image is formed when the real image is projected up through the microscope to the plane of the eyepiece?

Answers

Answer: flows through wires of flashlight.

Explanation: When the flashlight is turned on, the chemical energy stored in batteries is converted into electrical energy that flows through wires of flof the flashlightshlight. This electrical energy is then transformed first into heat energy and then light energy.

Which of the following conversion factors would you use to change 18 meters to kilometers? A. 1000 m/1 km
B. 1 km/1000 m
C. 100 m/1 km
D. 1 km/100 m

Answers

In converting a number with the unit of meter into kilometer we must use the conversion factor 1 km per 1000 meters.This is because in 1 kilometer there are 1000 meters and then the unit to be converted is already in meter so we need to divide it for us to convert.
