Which of the following results from a mark-recapture study done on mice would reflect a larger population size? when taking the second sample, 200 individuals are caught and 80 are marked from the first sample. both of these scenarios would result in the same population estimate. when taking the second sample, 200 individuals are caught and 20 are marked from the first sample.

Option (3).

Explanation:

Mark recapture method is used for the estimation of population size of an area. The individuals are identified by  some mark on them. The formula of mark recapture method is

N = M * C/ R

Here, N is the number of the individuals, M is the individuals are marked and captured, C is the individual captured again with mark or non mark and R is recaptured marked individual.

The individual with 200 population, 20 are marked for the first time represent the large population size.

Thus, the correct answer is option (3).

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!

protein makes up the building blocks of organs, muscles, skin, hormones and pretty much everything that matters in your body.

some choices are:

peanut butter

seeds

eggs

yogurt

meats

fish

so pretty much meat, dairy, nuts, and grains.
