Answer:

C. more examples of parallel play among the 4-year-olds.

Explanation:

Parallel play usually starts after the first birthday and will be decreasing when the child starts to interact more with other kids and stop being egocentric. This kind of play consists of playing among other kids, but without interacting with each other, they observe what the other kid is doing and do the same. 4-year-olds kids are still egocentric and do not interact a lot with their mates, while 8-year-olds kids interact with each other, are not egocentric, and have a different type of play.

Which of the following describes postural instability
kipiarov [429]

Postural instability

Explanation:

Postural instability is one of the main symptoms observed among people with neuromuscular disorders like Parkinson's Disease.

Postural instability basically refers to loss of balance or balance impairment of the body's posture due to lack of neuromuscular coordination that controls body movements.

  • Postural instability will make the person to lean backwards or forward without any control.
  • They develop increased probabilities to fall easily because of this tendency.
  • A person who takes a backward leap will walk due to retropulsion.
  • The person may walk in a hurry and taking very short steps due to festination.
  • It makes the person to suddenly freeze and stop while moving.
  • Postural instability may lead to stooped posture due to walking with drooped shoulder, leaning front or back, and bowed head.

The nurse is talking with a woman who is in her 2nd trimester of pregnancy who has been diagnosed with polyhdyramnios. The physi
Phoenix [80]

Babies with esophageal atresia will have an inability to swallow amniotic fluid leading to the builtup - this statement  by the woman indicates an understanding of the relationship between polyhdyramnios and esophageal atresia.

Explanation:

Polyhdramnios is the excessive builtup of amniotic fluid in the uterus during pregnancy.

Many congenital anomalies of the fetus are associated with a disturbance in the swallowing and absorption of fluids by the fetus. Anomalies like esophageal or duodenal atresia can lead to increased amniotic fluid retention.  

As the fetus grows, it swallows the amniotic fluid and maintains a balance between production and absorption of the fluid. Signs of polyhydramnios are visible with a huge belly of the pregnant woman's filled with the fluid and these are mostly detected in the late second trimester of pregnancy.  

Polyhyramnios with respect to the fetus reflects any congenital anomalies, heart or kidney problems, or fetal anemia.

8. Edible vaccines, a more controversial approach to vaccine development, have been investigated by scientists. Plants can be ge
IceJOKER [234]
After some research I found the important parts mostly bolded

Advantages:

1) Although the technology at first seems like something done for convenience rather than being something of significant utility, the fact is that poorly developed nations like India which have a relatively poor vaccination program are most likely to benefit from such a vaccine.
This is also the reason why many of the projects mentioned here (including Arntzen's early work) have been funded by the WHO.


 

2) Mucosal immunity : The vaccines which are given parenterally (e.g. Intramuscularly) induce a systemic response but little or no local immune response in the GI tract. This so called "mucosal immunity " is increasingly being considered very important for defense against GI pathogens. ( Remember OPV..)

3) And of course, it's painless and convenient

 


Disadvantages:

1) The vaccine dose would be inadequate if the patient eats only one banana/potato instead of the recommended two. Furthermore, there might be difficulties in judging the dose itself since the amount of antigen in each fruit cannot be accurately measured.

2) The risk of introducing a new gene into the Plant DNA population is not known. The gene may jump species and propagate into other plants (or wild varieties of the same plants). 
This may cause unpredictable results including a decrease in the number or even extinction of a particular plant species due to growth stunting caused by the viral/bacterial gene. (This has been known to occur in research studies, including Arntzen's)

3)"Oral Tolerance":  In another concern, scientists need to be sure that vaccines meant to enhance immune responses do not backfire and suppress immunity instead. Research into a phenomenon called oral tolerance has shown that ingesting certain proteins can at times cause the body to shut down its responses to those proteins.
This may cause the body to become more susceptible to a particular disease agent rather than become immunized against it.

All of the following are positive strategies for improving self-esteem except
bezimeni [28]
Well by the way you put the question it seems like there are supposed to be answer choices but, since there are none. I'll still try to answer the question as best as possible
1. Comparing yourself to others is a bad way of trying to improve self esteem
2. Overthinking and overworking yourself is a bad way to improve self esteem
3. Trying to raise confidence in yourself takes time so you have to be patient
And that's all I can think of right now but I hope it helps!
