fetal stage
Explanation:
Development begins around the ninth week and lasts until birth. This is when the embryo officially turns into a fetus.
From two months after conception until birth, the developing fertilized egg is known as a fetus. This follows earlier stages where the fertilized egg is known first as a zygote, then as an embryo before the ninth week of gestation.
From two months after conception until birth, the developing fertilized egg is called a fetus. The journey starts with a fertilized egg known as a zygote, which undergoes cell division and differentiation to form what is referred to as an embryo during weeks 3-8 post-conception. Starting from the ninth week of gestation until birth, this developing human is termed as a fetus. It is within this period that all of the organ systems continue their development, from their rudimentary form to a fully functional state.

Thank you!
Cell membranes are composed of what we call a "phospholipid bilayer" composed of phospholipids. Phospholipids have a hydrophillic (‘water loving’) head and a hydrophobic (‘water fearing’) tail. Water can get close to the hydrophillic head while it cannot pass through the hydrophobic tail, thus protecting the cell from foreign substances it does not need. Because of this dual property, the membrane can choose what substances may enter through it and this is what constitutes its semi-permeability.
One of the ways substances can enter through the membrane is through passive transport or diffusion, the movement of substances from higher concentration to lower concentration. This process does not require energy. Substances like oxygen and water easily diffuse through channel proteins when the concentration outside the cell is higher than the inside.
