Question

Why is it important for scientists to develop a way to grow tissues that have a built-in system to supply blood?

A lack of blood flow determines the number of cell layers that can survive when they are transplanted.
A lack of blood flow determines the types of tissues that can be grown in culture.
A lack of blood flow determines the amount of culture medium that is needed to keep a tissue alive.
A lack of blood flow determines the amount of time a tissue can be kept alive in culture.

Step-by-step explanation:

Answer 2

The answer would be: A lack of blood flow determines the number of cell layers that can survive when they are transplanted.

This question seems to talk about organ transplantation. Blood system is important to every organ as it supplies the food and oxygen. Lack of blood flow will decrease the food supplies, lead to starvation. This will limit the number of cell layers that survives as deeper layer will have less blood flow.
