Which of the following observations tells the biologist that the organism is eukaryotic? choose all that apply. a it has membrane-bound organelles. b it has a cell membrane. c it converts stored energy to use for cellular processes d it moves with flagella.

a It has membrane-bound organelles

b It converts stored energy to use for cellular processes

Explanation:

Prokaryotic cells lack membrane-bound organelles such as a nucleus and mitochondria, that are present in eukaryotic cells. However, they do have a cell membrane that separates the cell from the outer environment.

Prokaryotic cells do not have mitochondria to break down stored material into energy, instead they obtain their energy from light or chemical sources. This is in contrast to eukaryotic cells, which can break down sugars to produce energy.

Single celled prokaryotes and eukaryotes can both possess flagella

not sure but try c two haploid cells

explanation:

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!
