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.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )

a lot of people sadly don't know the best way to learn is cheating off of your friends or this amazing thing called google
