Answer: Mutations in the GALT, GALK1, and GALE genes cause galactosemia.
Explanation: Galactosemia is a disorder that affects how the body processes a simple sugar called galactose. A small amount of galactose is present in many foods. It is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas. The signs and symptoms of galactosemia result from an inability to use galactose to produce energy.Classic galactosemia, also known as type I, is the most common and most severe form of the condition. If infants with classic galactosemia are not treated promptly with a low-galactose diet, life-threatening complications appear within a few days after birth. Affected infants typically develop feeding difficulties, a lack of energy (lethargy), a failure to gain weight and grow as expected (failure to thrive), yellowing of the skin and whites of the eyes (jaundice), liver damage, and abnormal bleeding. Other serious complications of this condition can include overwhelming bacterial infections (sepsis) and shock. Affected children are also at increased risk of delayed development, clouding of the lens of the eye (cataract), speech difficulties, and intellectual disability. Females with classic galactosemia may develop reproductive problems caused by an early loss of function of the ovaries (premature ovarian insufficiency). Galactosemia type II (also called galactokinase deficiency) and type III (also called galactose epimerase deficiency) cause different patterns of signs and symptoms. Galactosemia type II causes fewer medical problems than the classic type. Affected infants develop cataracts but otherwise experience few long-term complications. The signs and symptoms of galactosemia type III vary from mild to severe and can include cataracts, delayed growth and development, intellectual disability, liver disease, and kidney problems.
Answer:
The answer is C: motor end plate.
Explanation:
The region where somatic neurons join a skeletal muscle is known as a motor terminal plate. These plates are formed by an axon and a muscle fiber. Depolarization is produced by a nerve stimulation activating the corresponding muscle; Each muscle has its own motor plate and its corresponding axon.
When you have a runny nose, "brain fluid leaking" typically isn't the first thing that comes to mind.
<h3>Why does CSF flow out of my nose?</h3>
The skull bone injury causes CSF to seep through the nose. Drainage of clear, watery fluid through one or both sides of the nose is the most typical sign of a CSF leak. When bending forward, tilting the head, or straining, this leaking can get worse.
<h3>Why is clear fluid dripping from my nose?</h3>
Allergies and illnesses like the common cold and influenza are the most frequent causes of clear liquid pouring from the nose. Another cause of a persistent runny nose is vasomotor rhinitis, in which there is no obvious reason why the condition exists. A leaking nose can be caused by nasal polyps, migraines, foreign bodies, and, very rarely, certain tumors.

Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).
