I need help with this ASAP I’ll give brainliest :))) To begin, design a solar model that meets the given criteria:

projected lifespan of the sun based on its initial mass
location of nuclear fusion within the sun based on its star age and mass
types of energy released due to nuclear fusion
approximate ratio of hydrogen and helium in the sun’s core based on its current age.
Your model can be an illustration or diagram of the given criteria. You may choose to draw it freehand and photograph the drawing for your instructor, or you may use a computer program to digitally create your model.

Each pair of clay balls represents two planetesimals. if each planetesimal is composed of the same material and is separated he the same distance, which pair experiences the frayed gravitational attraction?

What is the similarities and differences between bacteria and eukaryote?

Female luna moths (actias luna) attract males by emitting chemical signals that spread through the air. a male hundreds of meters away can detect these molecules and fly toward their source. the sensory organs responsible for this behavior are the comblike antennae visible in the photograph shown here. each filament of an antenna is equipped with thousands of receptor cells that detect the sex attractant. based on what you learned in this chapter, propose a hypothesis to account for the ability of the male moth to detect a specific molecule in the presence of many other molecules in the air. what predictions does your hypothesis make? design an experiment to test one of these predictions.
