The cell membrane is semi permeable in nature, that is, it allows the passage of some substances while it disallows some substances. Small and non polar molecules pass quite easily through the cell membrane but large and polar molecules can not do this.
The substances which can easily pass through the cell membranes make use of passive transports such as diffusion and facilitated diffusion to enter the cells while substances which can not pass through the cell membranes on their own make use of active transport. Examples of active transport are endocytosis and ectocytosis,
The phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase.
The series of canals used to transport materials throughout the cytoplasm in the cell is Endoplasmic reticulum. It comprises of the rough endoplasmic reticulum, with the ribosomes attached to its surface and the smooth endoplasmic reticulum( no ribosomes attached)
The questions which could be answered using the results of this investigation include:
- Is hair length in German shepherds a dominant or recessive trait?
- Is long hair in German shepherds an inherited trait?
- What percentage of offspring in the second generation of German Shepherd's are homzygous for the recessive hair length trait?
<h3>What is an Investigation?</h3>
This involves the process of searching for facts in order to solve a complex situation.
The cross breeding of the two German shepherds with various features will give rise to the questions given above.
