[#386] First clone Dolly was made in
Correct Answer
(A) Sheep
Explanation
Solution: First clone Dolly was made in Sheep. Dolly (5 th July 1996 - 14 th February 2003) was a female Finn-Dorset sheep and the first mammal that was cloned from an adult somatic cell. She was cloned by associates of the Roslin Institute in Scotland, using the process of nuclear transfer from a cell taken from a mammary gland. Her cloning proved that a cloned organism could be produced from a mature cell from a specific body part.
[#387] Gestation period for swine
Correct Answer
(C) 114 days
Explanation
Solution: Gestation period for swine is 114 days. Fetal development occurs between attachments of fertilized embryos to the uterus, to the days right before parturition (birth). The length of time a sow is pregnant, or gestating, is about 115 days, or 3 months, 3 weeks, and 3 days. During this time the piglets go through different phases of development, which we will separate into 5 major phases: Day 0 - 15, Day 13 - 30, Day 30 - 77, Day 77 - 90, Day 90 - 114.
[#388] Hormone for milk secretion
Correct Answer
(C) Prolactin
Explanation
Solution: Hormone for milk secretion Prolactin. Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk. Prolactin levels decrease as lactation is established but nursing stimulates prolactin release from the pituitary which promotes continued milk production. Prolactin is secreted into milk at levels representative of the average circulating concentration.
[#389] Which of the following glands secretes oxytocin
Correct Answer
(C) Pituitary
Explanation
Solution: Pituitary glands secrete oxytocin. Pituitary gland (also known as hypophysis) is a small, pea-sized gland located at the base of your brain below your hypothalamus. It sits in its little chamber under your brain known as the sella turcica. It's a part of endocrine system and is in charge of making several essential hormones like oxytoxin. Oxytocin is a natural hormone that manages key aspects of the female and male reproductive systems, including labour and delivery and lactation, as well as aspects of human behaviour. Hypothalamus makes oxytocin, but your posterior pituitary gland stores and releases it into your bloodstream.
