X is mathematically an unknown.
One structure that can be found is most plant cells is chloroplast. A plant cell may have around 0 to 20 chloroplast, depending on their location in plant or their function.
Chloroplast is the structure that photosynthesis occurs. Photosynthesis is the method that plant make food for themselves. They turn sunlight into food such as starch.
Plants are autotrophs, which means they make food themselves, they don't need food from other sources like animals. Therefore, chloroplast is not found in animal cells because we are heterotrophs, we feed on other food.
Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Explanation: First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)
Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid
The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Hope this helps :)
