I believe it relates because as we know the cell membrane is permeable meaning that allows oxygen, carbohydrates, food to enter the cell but it doesn't allow the entrance of large molecules that harm the cells.
After all the movement around it, matters because for example without food the mitochondria won't be able to create the energy and then with that energy, the nucleus to use it to complete the main the activities of the cell.
Hopefully this what you meant when you asked the question. Have a nice day/evening
Answer: A) By increasing the need for genetic engineering of fish
Fish is a globally accepted source of food, with the increase in population all over the world the demand for fish as a source of food is also increasing. Genetic engineering is a field of biotechnology in which the genome of the organism is manipulated by addition, deletion or substitution. This is done to improve the productivity of the animals and plant crops and to obtain desires characteristics in them.
A) By increasing the need for genetic engineering of fish is the correct option which can directly improve fish agriculture because a fish species can be genetically modified so that it can be able to produce more number of offsprings and nutritious quality of flesh, useful for human consumption.
The horse and donkey, though closely related by sharing a common ancestor, are different species. They have different number of chromosomes hence pairing of homologous chromosomes during fusion of gametes becomes complicated. The mule will have an extra chromosome from the horse hence will have abnormalities such as sterility. A Mule is unable to reproduce due to this same phenomenon. Homologous chromosomes are not well paired for meiosis I.
