Explanation:

Iron deficiency is one of the most common nutritional deficiencies in premenopausal women. Iron is a vital part of hemoglobin, which carries oxygen to red blood cells. Why do you think premenopausal women need more iron than men of the same age?

Answers

When a woman is entering her premenopausal state, fewer eggs are there for the ovaries to keep stimulating, so there is a high loss of iron in her menstrual blood.

So, a woman needs more iron than a man of the same age, because she is more prone to iron deficiency due to her loss of blood.

Answer:Premenopausal women shed blood as part of menstruation every month, which lowers the level of iron in the body. So, they need more iron than men and are also at a greater risk for this nutritional deficiency.

We can measure the length of an object using the units of measurement 'hand span,' 'forearm length,' or 'footstep.' Hand span, forearm length, and footstep, on the other hand, cannot be used as standard unit measurements because their length varies from person to person.

To conclude, the old system of measurement isn’t accepted anymore because it would not be accurate.

You are transporting an unresponsive intubated 4-year-old child. An IO catheter is in place, and you are ventilating the child at an age-appropriate rate. Suddenly, the child becomes cyanotic and experiences a significant drop in her heart rate and oxygen saturation, and loss of a capnographic waveform. You attempt to auscultate her lung sounds but are unable to hear over the drone of the engine. You should:
A. look for vapor mist in the ET tube and attach a colorimetric device.
B. extubate immediately and ventilate with a bag-mask device.
C. increase your ventilation rate and reassess the child's condition.
D. administer 0.02 mg/kg of atropine via rapid IO push and reassess

In what organelle do the Kreb's cycle and the electron transport chain take place?
(1 point)
0. chloroplast
O mitochondria
O cytoplasm
o nucleus

Answers

Answer:

mitochondria

Explanation:

-The aerobic phases of cellular respiration in eukaryotes occur within organelles called mitochondria. These aerobic phases are the Krebs Cycle and the electron transport chain.

The Kreb's cycle and the electron transport chain take place in the MITOCHONDRIA.

Cellular respiration is an aerobic process, i.e., a metabolic process that requires oxygen (O2) by which energy from foods is used to synthesize ATP, carbon dioxide (CO2), and water (H2O).

The three stages of cellular respiration are glycolysis, Kreb's cycle (also known as the citric acid cycle), and the electron transport chain.

Glycolysis is an anaerobic pathway (i.e., does not require O2) and occurs in the cytoplasm.

The Kreb's cycle and the electron transport chain (ETC) are both aerobic processes that occur in the intern membrane of the mitochondria.

In conclusion, Kreb's cycle and the electron transport chain occur in the mitochondria.
