Which best describes what is occurring in this population of squirrels? number of squirrels entering and leaving a population after 1 yearcause of changenumber of squirrelsdied from predation-2 born- 4immigration-10left to find food-3died from disease-8left to find a mate-3a. population growth is decreasing. b. population growth is increasing. c. population growth stays the same. d. population reaches carrying capacity.?

A is the answer. Population growth is decreasing.

Explanation:

The formula is (birth rate + immigration) - (death rate + emigration). So, 4+10=14, 2+3+8+3= 16, 14-16 = -2. -2 is a negative number, meaning population is decreasing. Hope this helped!

i dont know this but ask your teacher for !

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!
