Analyze how different concentrations of solutes in a solution can affect organism's cells.

1 answer:

4 0

Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.

Stage 1: which is characterized by high high birth and death rates. ALso known as pre-transition stage.
Stage 2: Characterized by falling death rate but continued high death rate. Also known as early transition stage.
Stage 3: characterized by a decline in birth rate and deceleration of population growth. It is also known as late transition period.
Stage 4: Characterized by low birth and death rate. Negligible population growth. Also known as post-transitional period.

Define the terms phenotype and genotype, and describe the relationship between them

Roman55 [17]

Genotype

DEFINITION

IT IS THE GENETIC MAKEUP OF THE CELLS.

Phenotype

DEFINITION

IT IS PHYSICAL APPEARANCE OF ORGANISMS.

The Genotype, carried by all living organisms, holds the critical instructions that are used and interpreted by the cellular machinary of the cells to produce the r Phenotype of the organism.

Thus, all the physical parts, the molecules, cells and other structures, are built and maintained by cells following the instructions give by the genotype.
