Answer:
Out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Explanation:
As we all know, that rate of diffusion is linked to the surface area--to--volume ratio. Larger surface area--to--volume ratio depicts that the surface area of an object is higher that than of its volume. The higher surface area provides higher area for diffusion.
Thus, any smaller object with larger surface area--to--volume ratio will provide higher diffusion rate and hence the time for diffusion will decrease.
While any object with smaller surface area--to--volume ratio will provide lower diffusion rate and hence the time for diffusion will increase.
Thus, out of two objects the one with ratio of surface area to volume equal 2.2 m-1 will have higher diffusion rate and hence will take less time in a diffusion test
Answer:c
Explanation: I did the same quiz and the answer is c
Answer:
The involvement of more than two genes.
Explanation:
The polygenic characteristics have many phenotypes because more than two genes governs the phenotype of individual organism. The single gene contains a pair of alleles that codes for two phenotype and two genes will code for 4 phenotype. Thus, more than two genes for example, three genes will have six phenotypes.
The skin color and height are polygenic characterstics in humans.
Answer:
A B and C but not D
Explanation:
Moving from a Hight concentration gradient to a low concentration gradient means moving from an area where a substance in quantity to an area where it is lower in quantity. D is the only one showing something to be moved against a concentration gradient because there are more squares inside the cell than outside the cell yet the squares are still being moved into the cell.
