Answer:
The correct option is D: An 11-month-old girl may show anxiety when her mother goes into another room.
Explanation:
Option C is wrong because: A 5 month old baby will not develop fear of strangers and separation anxiety because it is between the age of 4 to 6 months that they begin to develop vision, which means that they may not have the ability to distinguish between their mother and strangers.
Option B is wrong because Young infants begin to experience distress and contentment even before they are 12 months.
Option A is wrong because at 12 weeks, which is 3 months, the baby still uses sound and not facial expression. Hence at, three months, a baby is more likely to smile to a sound from a person rather than in response to a smile.
The correct option is D: At 11 months, a baby's vision is clear and can differentiate between his parents and others, and at this point they begin to show some emotions like anxiety, fear and others.

In this case, the emt should: <span>assist the patient's ventilations with a bag-valve mask.
The key factor of this diagnosis is the cyanotic skin. Cyanotic skin is a discoloration on the skin that's most commonly caused by low oxygen saturation (probably related to the diabetes). As a first aid, the emt should make it easier for the patient to inhale as much oxygen as possible.</span>
Answer: B, D, and E.
Explanation:
Birds and reptiles are most closely related, Frogs are more closely related to birds than fish and fish are the most primitive are three statements that are correct because a cladogram is considering a diagram that is used in cladistics.
This type of diagram is there to show relations between organisms and in this case, it is true that birds and reptiles are related most closely, frogs are more closely related to birds and the fish( C is incorrect) is the most primitive( that is why answer A. is not correct).
