Answer:

C. The moon's gravitational pull and Earth's rotation

Explanation:

The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

the salivary glands, stomach, and pancreas secrete ____________ enzymes to break down triglycerides into monoglycerides, fatty a

likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

A primipara tells the nurse that her baby is breathing very rapidly and that the breaths are irregular. she expresses fear that

Nastasia [14]

For a nurse it is quite normal because she knows the pattern of breathing of a small baby but for a primipara ( a lady who is giving birth for the first time ) it might not be acceptable to understand the fact that a newly born baby has an irregular breathing pattern switching in between fast and slow .

As she is a new mother she might not be aware of the fact that a baby breathes very fastly to compensate the amount of energy required to maintain the homeostasis of the baby.As the baby is in growing stage the amount of energy required is much more as compared to that of adults.

Hence , the nurse will not take any medical action as the baby is not sick but yes she will definitely tell the mother that it is normal in baby

HELP ME PLZZZZZZ!!!!!!!!!!!

Answer:

Explanation:

Objective(s): To see what will happen to the egg after soaking in water for 72 hours checking it every 24 hours

Hypothesis: I think the egg will get very thick because it will absorb the water

Variables:Independant: The circumference is measured every 24 hours

Dependant: the circumference

Control: The same unit of measurement was used ( CM)

Materials:

Raw egg

String or thread or yarn

Ruler

White vinegar

Tap water

Syrup

Jar with lid (like a mayonnaise jar or something big enough to put the egg in)

Procedures:

Data and Observations:

Record your observations from the experiment in either the hands-on lab or the teacher-led video. Don't forget to include at least two detailed observations and the measurement of the egg's circumference in centimeters.

Time (hrs) Observations Circumference (cm)

0 the egg looks normal: 53 CM

24 Its starting to get bigger: 54 CM

48 It wont start getting bigger: 56 cm

72 Its huge: 57 CM

Conclusion:My hypothesis was correct. I knew the egg would get bigger because the water would absorb into the egg. The egg grew 4 cm

Was your hypothesis correct? Why or why not?My hypothesis was correct. I knew the egg would get bigger because the water would absorb into the egg.

How much did the egg change in size? (answer should be in centimeters)The egg grew 4 CM

Refining the Experiment:

Continue this experiment by removing the egg from the water and covering it in syrup. Be sure to allow at least 24 hours before making your observations. Handle the egg very carefully!

Predict what will happen to the egg and syrup system.

When refining your procedures describe the following:

How will the change in the syrup and within the egg be measured or identified?

How will you determine when homeostasis has been reached in your egg and syrup system?

Be sure to address each bullet in the conclusion of your lab report:

Was your hypothesis correct? Why or why not?

How much did the egg change in size? (answer should be in centimeters)

SORRY I DIDN'T HAVE TO DO THIS PART ON MINE.
