Which part of an animal forms a thin layer around outside?
cell membrane
In what way is an ovum adapted to carry out its special role?
The ovum is bound by many membranes preventing the breakage of it. The ovum contains food which is essential for the developing zygote. It forms a fertilization membrane after fertilization to prevent the entry of the other sperms.
How does osmosis explain the fact that watery syrup forms when you put sugar on strawberries?
Osmosis is the diffusion of water across a membrane from the side of higher concentration to lower concentration. When sugar is placed on strawberries, the water diffuses across the cell membranes out of the strawberries and mixes with the sugar to form a syrupy substance.
What is the most significant difference between precambrian life forms and paleozoic life forms?
The Precambrian life forms were less developed than the Paleozoic life forms.
Where can you find simple squamous epithelium?
The skin of amphibians is made of that kind of epithelium, but mostly, they are found in capillaries (circulatory system) and alveoli (lung), they are needed where it is necessary to have rapid exchange by diffusion.
The extraembryonic membrane that forms the fetal portion of the placenta is the?
The chorion.
What forms the stalk of the umbilical cord?
newtest3eggs
What forms the umbilical cord?
allantois
What membranes forms the umbilical cord?
allantois
What are the combining forms for the umbilical cord?
omphal/o
Where is respiratory change made in a fetal life?
In simple words respiration means exchange of gases.The fetus or foetus is actually a more developed form of an embryo when it has acquired its basic forms although the sources of oxygen to the fetus are the placenta and umbilical cord.
What is the double layer of phospholipids?
The double layer of phospholipids is called the phospholipid bilayer. It forms the basis of every membrane, both the plasma membrane and all internal membranes.The idea that the bilayer has protein molecules embedded in it is the essence of the fluid mosaic model of the cell membrane.
What is a small sac that forms part of a cell membrane?
A vesicle forms as a small sac from the cell's membrane.
Which type of molecule forms the cell membrane?
The basic structure of cell membranes is a phospholipid bilayer. Phospholipids have a phosphate group (the head) and a lipid tail.
What forms from a peice of membrane breaking loose from cell membrane?
vacuoles
What visceral membrane forms part of the filtration membrane?
glomerular capsule
What is the membrane that forms the embryonic side of the placenta?
The placenta is completely formed by 10 weeks, by the joining of the decidua basalis (maternal side) and chorionic villi (fetal side). The chorion and amnion are the placental membranes. The Chorion is the membrane furthest from the embryo, and the amnion in the inner layer that is closest to the embryo.
