A true-breeding black rabbit is crossed with a true-breeding white rabbit to produce an F1 generation of 16 individuals. If the black color trait is dominant, 0 black rabbits, 0 white rabbits, 8 grey rabbits outcomes represents the expected phenotype of an F1 generation cross.
1. Pathogens enter the body through a cut in the skin 2. Cells recognize the foreign invaders 3. Histamine is released 4. White blood cells travel to the invaded area
The two lines on the outside of the chloroplast indicate a double membrane: True
The Golgi apparatus is not shown in this cell but this does not mean that this organelle does not occur in the cell: True
The relative dimensions and placement of the membranes and organelles in this model are exact representations of those structures in a living cell: False
The large structure in the center is a nucleus: False
This cell is capable of photosynthesis: True
Explanation:
Chloroplast, like mitochondra, have double membrane called the chloroplast envelope. Hence the first statement is true.
Golgi apparatus is found in all plant and animal cell. It is usually located close to endoplasmic reticulum. Hence this statement is true.
The relative dimensions and placement of the membranes and organelles in this model are not an exact representation of those structures found in living cell. Hence its a false statement.
The large structure in the centre is vacuole and not nucleus. Hence its a false statement.
Since its a plant cell so it is capable of photosynthesis. Hence its a true statement
