Mr. hernandez is explaining how the gravitational forces of the moon and the sun pull the water in the earth's oceans causing tides he used a basketball to represent the sun and a golf ball to represent the moon. what would be a good object to represent earth and to show the effects of gravity on it?
a tennis ball
b basketball
c light bulb connected to battery
d balloon not fully inflated

Tennis ball

Explanation:

Tennis ball is of size in between the size of basket ball and golf ball. In reality earth is larger than moon but extremely small as compared to the size of sun.

Thus, when sun and moon are kept in front of each other with earth in between, then the size of earth prototype must be adequate enough to stop the passage of sun light to the moon just like the way it happens in nature. Therefore tennis ball be the best option among all.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

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!
