Answer:
proteins
Explanation:
Transport protein is responsible for the movement of molecules across the cell membrane. This process occurs in active transport. Active transport is a type of transport in which energy is used in the form of Adenine tri phosphate (ATP) to move particle across semi-permeable of the cell. Molecules such as nutrients, Sodium, glucose, oxygen and carbondioxide can pass through it.
This procedure is called In Vitro Fertilization (IVF)
The gene which is produced once or twice in a lifetime is the milk producing hormone after childbirth. This is because it is produced only after the birth of the child. The growth of the mammary glands takes place during pregnancy. The breast continue to increase in size after giving birth to a child. After delivery only copious milk is produced which is generally done with the help of milk hormone. During pregnancy the secretion of the milk is inhibited by the estrogen and progesterone which circulates in the blood stream which in turn inhibits the release of prolactin from the pituitary gland thus making the mammary glands unresponsive. Where as insulin is a hormone which helps the body to utilise the sugar or glucose from different sources like carbohydrates that we get while we eat food and adrenaline is secreted when we are scared or when we feel that we are in danger. Therefore, milk producing hormone is the gene that are turned once or twice in a lifetime.
