Differentiating cells delete the dna for genes they do not need.
a. True

Answers

The answer is false

The nurse hears a pregnant client yell, "oh my! the baby is coming!" after placing the client in a supine position and trying to maintain some privacy, the nurse sees that the neonate's head is being born. what should the nurse do first?

Answers

In an emergency in which the neonate's head is already delivering, the first action by the nurse should be to check for the presence of a cord around the neonate's neck. If the cord is present, the nurse should gently remove it from around the neck. The mother should be told to breathe gently and avoid forceful bearing-down efforts, which could lead to lacerations. Although blood and bodily fluid precautions are always present in client care, this is an emergency. If possible, the nurse should put on gloves. Suctioning the mouth can be done after the nurse has checked that the cord is not around the neonate's neck. Telling the mother that help is on the way is not reassuring because emergency medical technicians may take some time to arrive. Delivery is imminent because the neonate's head is delivering.

Answer:

To check for the presence of cord around the neonates neck.

Explanation:

In such a case as given in the question where the neonate's head is already delivering, the first action by the nurse should be to check for the presence of a cord around the neonate's neck.If the nurse finds out that a cord is present around the neonate's neck then she should gently remove it from around the neck. Further, the nurse should tell the mother to breathe gently and avoid any forceful movements and should start preparing for the delivery immediately.

What factor would account for a strong synovial joint? what factor would account for a strong synovial joint? small reinforcing ligaments synovial fluid low muscle tone the deepest articular surface?

Answers

Final answer:

The strength of a synovial joint is largely influenced by the ligaments that reinforce it, along with the presence of an articular disc and the supportive role of muscles and tendons.

Explanation:

Factors that contribute to the strength of a synovial joint include the robustness and arrangement of ligaments that surround and reinforce the joint. These ligaments hold the bones together and prevent excessive or abnormal joint motions. Moreover, the presence of an articular disc, such as a meniscus, can enhance the stability and strength of a synovial joint by providing additional cushioning, smoothing bone movements, or binding the bones more firmly. It's also important to acknowledge that muscles and their tendons contribute to joint strength by providing contractile force that indirectly supports the joint during movement.

​in which would the letter "p" be fastest recognized by an individual who spoke english

Answers

I found the exercise on the internet and these were the options:
"-Help
-Pelh  
-Elhp  
-Pleh"

The letter "p" would be fastest recognised by an English speaker in "Help". Letters are more recognisable when they are in a context that's known. If any of the other words was given to an English speaker to memorise, he would probably memorise the letter by letter, while with "help", he would be able to know straight way  what letters were contained in it without having to make a conscious effort to memorise them one by one. Because of this, the letter "p", for an English speaker would be the fastest recognised in the word "help" rather then in other unknown word.

The Diving Board Peering into the glassy, clear water, Aiden never imagined that standing on the edge of a diving board would feel like peering over the edge of the world. After all, it was only six feet up, but from where he was positioned, it felt like an insurmountable sixty. As the sweltering heat of the Sun beat down on his neck and back, the board slightly pulsated up and down from the weight of his body. This created a queasy, uneasy feeling in Aiden's stomach and it was one that he was not unfamiliar with. As he stood on the diving board squinting down at his friend Gavin, he remembered back to the beginning of middle school and the terror he experienced in Mrs. Erdon's English class. Seventh grade seemed like it was just yesterday, but he had to admit that a lot had transpired in two years. Because he was leaving his elementary school and beginning middle school, Aiden had an immense amount of fear and angst. Besides the fact that the new school was twice the size of his previous one, the student body was also enlarged which added to his anxieties. Furthermore, his older brother told him that the teachers would be rigorous and the classes more demanding; he questioned how he would ever survive in this jungle. Thankfully, he had English class first period which was his preferred subject, and to improve matters, his best friend Gavin was in the same class. Gavin and Aiden had been comrades since second grade and they complemented each other in just about everything. Where English was Aiden's best subject, it was Gavin's worst; Gavin made up for this in math though and often helped Aiden with his algebra homework. Now, at a new school and on a fresh adventure, the two boys were resolved to face whatever was going to come their way. Approximately four and a half minutes later, their determination disappeared when Aiden and Gavin picked up their class schedules and found out that they had the notorious "Mrs. Erdon" for English.
