Astudent is investigating cellular transport. she fills a beaker with 250 ml of water. she places 10 drops of red food coloring into the beaker of water and makes an observation immediately, after 5 minutes, and after 30 minutes. her set up is shown below. image the student observes that the molecules of red dye move from an area of higher concentration to an area of lower concentration until equilibrium is reached. which best describes the type of cellular transport that the student is investigating? a the student is investigating the passive transport of diffusion. b the student is investigating the active transport of osmosis. c the student is investigating the active transport of diffusion. d the student is investigating the passive transport of osmosis.

The correct answer is A The student is investigating the passive transport of diffusion.

Explanation:

Diffusion is a type of transport process which helps in the transport of small molecules and gases towards their concentration gradient that"s means from region of high concentration to the low concentration region untill equilibrium is reached.

       In this question the 10 drops are red coloured food particles that are placed into the beaker, diffuses to all the regions of the beaker untill the concentration of that red colored food particle become same in all the regions to which red colored food particle diffuse.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
