It is expected to see in the offspring of a woman who has DMD and a man who does not have the disease that all of their sons and none of their daughters will have the disease

Option A.

<h3><u>Explanation:</u></h3>

Duchene muscular dystrophy, also known as DMD is a recessive, x-linked disease. It occurs when there is a mutation in the dystrophin gene. This mutation further affects the muscles of the body leading it to degenerate and ultimately death.

When a woman with DMD and a man without DMD have an offspring, their daughters and the sons will get the mutated gene signature from the mother as she is the carrier. But since the father has normal genes, the daughters will become the carriers and will not be afflicted by it. This is because the normal X chromosome from the father will be passed on to them. The sons on the other hand will have the disease as they will get one of their mother's X chromosome which would be carrying the mutated gene.

tatyana61 [14]

Answer:

Nature is alive and effective 24 hours a day. Moon flowers are nocturnal bloomers, best enjoyed by late night strollers and night owls.

Post sunset, these magnificent, light-reflecting white flowers bloom and glow all night long – hence their name. However, when the sun begins to rise, they close their perfectly perfumed flowers tightly shut. Although moon flowers are predominantly white, they are also available in rich reds and vibrant yellows, all of which will add contrast to your floral display.

Although extremely beautiful, several species of moon flowers are very poisonous. It’s therefore a good idea to exercise caution when choosing late night bloomers for your garden.

Why do scientists use weather and climate maps?
Nikolay [14]

Climate classifications help people know what types of conditions a region usually experiences through the year. Rather than having to describe the full range of conditions observed in a region over each month or season of a year, a classification scheme can communicate expected conditions using just two or three terms

For each phrase below, choose the most appropriate key term from the list above
natali 33 [55]

Answer:

a. Drug abuse

b. Inhalants

c. Stimulants

d. Neonatal abstinence syndrome

e. Club designer drugs

f. Depressants

Explanation:

Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.
