The answer is the apoplast, the symplast, and the transmembrane pathway.
1. The apoplast pathway occurs through cell walls and space between cells. So, water does not cross any cell membrane as it travels this pathway.
2. The symplast pathway occurs through the continuum of cytoplasm. So, water travels through plasmodesmata which connect cells.
3. The transmembrane pathway occurs across cell membranes. So, water enters the cell on one side of the membrane and exits on the other.
To find the similarities and differences in organisms by using possible chromosome and physical characteristics.
Natural selection states that the most advantageous trait in a species will become more common in the population, and can even replace other non useful trait over time. That is evolution by natural selection. In the case of anteaters, these animals became better adapted to the environment by growing a longer snout to have better access to food (ants).
Answer:
Explain how genes are expressed for a particular trait?
Genes are expressed phenotypically as it reflects through dominant gene which are represented through physical means such as height, skin color, shape e.t.c
Explanation:
The solution might be hypotonic.
When a drop of blood is added in the hypotonic solution, it may hemolyse Or bursting of cell take place, this is because the solvent comes inside the cell due to lower concentration of solute and it becomes hemolysed.
There are three types of solutions.
- Hypertonic condition of the solution occurs when the concentration of solute outside is higher than that inside the cell.
- Hypotonic condition of the solution occurs, when the concentration of solute outside is lower than that inside the cell.
- Isotonic condition of solution occurs when concentration of dissolved solute outside is equal to the concentration of solute inside the cell.
