A baby is assessed at one minute after birth using the Apgar scale. Three of the five vital signs are good, but the baby is weak
timama [110]

Answer: The two vital signs the medical team is concerned about are:

1. MUSCLE TONE

2. REFLEX IRRITABILITY

Explanation:

What does APGAR stand for, and what does it measure?

When the scoring system was put into common use, medical professionals created an acronym using Apgar’s last name, so that each criterion included in the assessment would be easier to remember. The five criteria assessed in the Apgar score are:

A – Appearance (skin color)

This is an evaluation of the baby’s skin color. The medical team measures if the baby blue or pale all over, blue at the extremities, or pink all over.

P – Pulse (heart rate)

During this evaluation, the medical team measures if the baby’s heart rate is absent, slow (<100 beats per minute (bpm), or fast (>100 bpm).

G – Grimace (reflex irritability/response)

During this evaluation, the medical team asks if the baby lacks a response to stimulation, responds with a grimace, or responds by crying and pulling away.

A – Activity (muscle tone)

During this evaluation, the medical team asks if the baby is limp, if the baby has some flexion (joint movement), or if the baby shows active motion.

R – Respiration (breathing ability)

During this step, the medical team asks if the baby is failing to breathe, if the baby has a weak cry and slow breathing, or if the baby is breathing well and crying normally.

<u>Answer:</u>

<em>The south beach in Florida is at high risk of flood from high tide.</em>

<u>Explanation:</u>

Even at the no rain days the sea level of the south beach rises creating a fear for the resident about the flooding. The cities in the Florida are maximum on the limestone, so it is obvious that water will rise through it very soon.

The interaction between the sun and moon causes the high tides to occur even in the sunny days.

In what way(s) can mRNAs be processed? In what way(s) can mRNAs be processed? By adding caps and tails to the ends of the mRNAs
sergejj [24]

Answer:

<h2>All of the above are ways in which mRNA can be processed.</h2>

Explanation:

DNA is transcribed into pre-mRNA which is further processed into mature mRNA. mRNA be processed by various ways: as at the 5' end of RNA, addition of capping occurs,  and at the 3' end, there is addition of large number of adenosine ( approx 200), known as polyadenylation.

RNA splicing is the process of removal of introns and of addition of exons, through which only coding sequences (exons) remain in the mature mRNA and non coding regions(intron) are removed.

Alternative splicing may produced various type of mRNA from a single type of pre- mRNA.
