You are the RN starting your shift on a pediatric unit. You are taking care of a 7-month-old infant who has been alert and behaving in an age-appropriate manner on the previous shift. When you perform your first assessment, his parents tell you that in the last hour, he has become sleepier and did not cry when the lab technician drew blood a few minutes ago. Your response is to
A. encourage the parents to keep the room quiet to allow him to sleep.
B. document it and plan to recheck him in an hour.
C. tell his parents to make him wake up because it is not time for him to go to bed.
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding. And can lose alertness and pays less attention to sounds and the baby is always drowsy. The registered nurse has to assess this baby immediately because lethargy could happen because the baby may have an infection or probably have low blood sugar. Therefore the last option is the best option for the nurse to take.
Translate the mRNA codons into the
amino acid sequence.
(DO put a comma and a space between the codons and make sure you spell out the names of amino acids!)
Answer:
mRNA sequence: AUG; GCU; AAU; UGU; UGA
protein sequence: Met-Ala-Asn-Cys-stop codon (Methionine-Alanine-Asparagine-Cysteine-stop codon)
Explanation:
Transcription is the process by which a fragment of DNA (e.g., a gene) is used as template to synthesize a complementary RNA sequence, usually a messenger RNA (mRNA) sequence that is then used to synthesize a protein by the process of translation. In RNA, Adenine bases are replaced by Uracil bases. During translation, each codon (i.e., each triplet of nucleotides of the mRNA) indicates a specific amino acid (according to the genetic code). UGA, UAA, and UAG are stop codons that signal the end or termination of translation.

For the study of a particular drug, Marcus proposes an experiment with a particular population. Approximately 200,000 people in the United States take this drug. He started out with a sample size of 300 people. First, he conducts research on the medical history of the people in his study. He collects the information using reliable sources. He decides to repeat the experiment using a larger sample size.
The missing part of the question is as follows:
Phrase indicates a limit to the scientific accuracy of the experiment?
Answer:
The correct answer is - a sample size of 300 people.
Explanation:
In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.
The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.

The growth of two plant saplings A and B, were observed for a period of 6 months. The graph shows the linear growth of the saplings, in centimeters.
Which sapling shows the greatest amount of growth during the 6 month time period? Explain.
Answer:
Sapling B
Explanation:
Since month 2 is the first month that is a point that has an ordered pair, you would take 10/2, which is, and Sapling A has its first full ordered pair at 50,3 then you would take 10/3, which is 3.3. So 5 is greater than 3.

Which change would best aid a farmer in making the transition from conventional farming techniques to more sustainable farming techniques?
Answer:
The correct answer is - Rotate the types of crops grown.
Explanation:
Crop rotation is the practice of growing the different types of crops sequentially on the same field to improve nutrients in the soil for better soil health and helps in fighting pest and weed pressure.
Different crops required different nutrients and therefore, rotating crops helps to not exploiting the same nutrients again and again. Rotating crops also helps in removing weeds and pests as different weeds and different pests associate with different crops.

Describe & explain why the effect of temperature as a
limiting factor for photosynthesis is different to the
effects of Co2 and light intensity.
Answer:
Although the light dependent reactions of photosynthesis are not affected by changes in temperature, the light independent reactions of photosynthesis are dependent on temperature. They are reactions catalysed by enzymes. As the enzymes approach their optimum temperatures the overall rate increases. It approximately doubles for every 10°C increase in temperature. Above the optimum temperature the rate begins to decrease, as enzymes are denatured, until it stops.
Explanation:
At low light intensities, as light intensity increases,the rate of the light-dependent reaction,and therefore photosynthesis generally, increases proportionately (straight line relationship). The more photons of light that fall on a leaf, the greater the number of chlorophyll molecules that are ionised and the more ATP and NADPH are generated. Lightdependent reactions use light energy and so are not affected by changes in temperature.As light intensity is increased further, however, the rate of photosynthesis is eventually limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph).Chlorophyll ais used in both photosystems. The wavelength of light is also important. PSI absorbs energy most efficiently at 700 nm and PSII at 680 nm. Light with a higher proportion of energy concentrated in these wavelengths will produce a higher rate of photosynthesis.An increase in the carbon dioxide concentrationincreases the rate at which carbon is incorporated into carbohydrate in the light-independent reaction, and so the rate of photosynthesis generally increases until limited by another factor.As it is normally present in the atmosphere at very low concentrations (about 0.04%), increasing carbon dioxide concentration causes a rapid rise in the rate of photosynthesis, which eventually plateaus when the maximum rate of fixation is reached.

i) Describe the function of stomata.
Answer:
Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
Explanation:
the main fiction of stomata is to open and close the pores in the leaves for an exchange of gases.
it allows the plants to take in carbondioxide and gives out oxygen for photosynthesis.

Which of the following molecules is not needed for the Calvin Cycle?
a. CO2
b. ATP
c. NADPH
d. H2O
pls help
Answer:
c. NADPH is the correct answer .
Explanation:
Hey mate..!
NADPH molecules is not needed for the Calvin Cycle.
The correct answer is water as the water molecules are produced during photosynthesis.
Co2 produces the starch from sugar. ATP and NADPH are also used to convert sugar molecules during the Calvin cycle.
Carbon enters the Calvin cycle as CO2 and leaves as sugar. ATP is the power source, even as NADPH is the decreasing agent that provides high-power electrons to shape sugar. The Calvin cycle absolutely produces a three-carbon sugar glyceraldehyde 3-phosphate (G3P).
What is the Calvin cycle?The Calvin cycle is a technique that plant life and algae use to show carbon dioxide from the air into sugar, the meals autotrophs want to grow. Every dwelling element on Earth relies upon the Calvin cycle. Plants rely on the Calvin cycle for power and meals.
Thus it's clear that it has no water needed.

Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.
