Nikoli was using a simulator to compare the gravitational force between the Earth and two different stars. He recorded his observations in the table below. Object Distance from Earth Force of gravity compared to Earth Gravitational
attraction between it and Earth
The Sun About 91 million miles About 28 times Earth Large
Alpha Centauri About 40 trillion miles About 28 times earth Very Small

Nikoli wondered why the gravitational attraction between the Earth and each star could be so different. What statement below accurately explains the difference in the gravitational attraction?

The gravitational attraction between the Earth and the Sun is larger because gravitational attraction increases as distance increases.

The gravitational attraction between the Earth and Alpha Centauri is smaller because gravitational attraction decreases as distance increases.

The gravitational attraction between the Earth and Alpha Centauri is smaller because the mass of Alpha Centauri is smaller than the mass of the Sun.

The gravitational attraction between Earth and the Sun is larger because gravitational attraction depends only on mass, and the masses of both stars are the same.

complete the square on the right side of the equation;

-5(x + 0)^2 + 15

answer: d. y = -x^2 + 15

the eggs of the insects should be the first thing collected at the scene.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!

thats not a question
