Answer:

A person will be lactose intolerant if they do not have the lactase enzyme.

Explanation:

Lactose is milk sugar, in technical terms, it is a carbohydrate formed by galactose and glucose. It is estimated that 75% of the world's population suffers from lactose intolerance, a digestive disorder in which carriers have partial or complete difficulty digesting sugar in milk and milk derivatives.

Lactase is the enzyme responsible for breaking down lactose in the blood, making sugar digestion easier. When there is a lack or insufficient amount of lactase in the body, sugar reaches the large intestine unchanged and accumulates.

Bacteria that produce lactic acid and gases ferment the accumulated lactose, leading to greater water retention, causing diarrhea, bloating and abdominal pain. This is the face of lactose intolerance.

3. From problem 2, suppose another boy, Boy C pulls the heavy cabinet with 5 N
kykrilka [37]

Answer and Explanation:

As you can see the boys are pulling in the same direction. This means that we have an example of an unbalanced force, also called the resulting force, since the forces are not canceling out. This whole situation will have a result which is to create an unbalanced net force to move the object or keep it in repayment and that is what we will discover.

First, let's find out what force the two boys exerted. This is very simple, we only need to add the force exerted by the two. 5N + 5N = 10N

The cabinet will be able to move if the force exerted by the two boys (10N) manages to overcome the resistance and the force exerted by the cabinet itself. If they manage to overcome the resistance of the cabinet, the cabinet will move towards the force applied by the boys.

Twins are twins who are nearly identical, whereas __________ twins come from two separate ova.
mrs_skeptik [129]

Monozygotic twins are twins who are nearly identical, whereas dizygotic twins come from two separate ova.

Monozygotic twins- Identical twins, also known as monozygotic twins, are produced when a single egg is fertilized by a single sperm, resulting in the fertilized egg dividing into two. Identical twins always have the same sex and have the same DNA.

Dizygotic twins- Dizygotic twins are two siblings that develop from different ova, or eggs, that are produced from an ovary at the same time and are fertilized by different sperm. They are also known as fraternal twins or nonidentical twins.

Ova- In most anisogamous species, the female reproductive cell, or gamete, is the egg cell, or ovum (plural ova).

A client has edema of the lower extremities with crackles in the lung bases. What diuretic is most likely to be prescribed for a
OLga [1]

Answer:

Furosemide e.g. Lasix

Explanation:

Furosemide is a diuretic/water pill that is used to treat fluid retention in the body. Diuretics increase the removal of salts from the blood, they also cause more water to be drawn out of the blood and into the urine.

It works by causing the kidneys to increase the amount of salts such as potassium and sodium that are filtered out of the blood by the kidneys and into the urine, when the salt is filtered out, the excess water is drawn with it.
