The third option: Increase the intensity of cardiovascular workouts, is the right one. we know this because the rest of the options don't give the right fit. anaerobic workout is a short burst of energy, so it wouldn't be a good fit. Doing fewer aerobic workouts would lower it even more. Decreasing intensity of a cardiovascular workout would also cause a larger decrease. so it is the third option. Hope this helps a lot.

Explain the biological structure hierarchy of the human body and the role of homeostasis in maintaining the body. Include the fo
Nuetrik [128]

Answer:

1. Biological structure of the human body

The human body is organized in different levels according to their complexity.

The levels are the folowing (increasing complexity).

1. Atom (N, O, C,..)

2. Molecule (Protein, lipids, water...)

3. Organelle (mitochondria, golgi apparatus,...)

4. Cell (blood cells, bone cell,..)

5. Tissue (connective tissue, epithelial tissue,..)

6. Organ (lungs, kidney,..)

7. Organ system (skeletal system, muscuar system,...)

8. Organism (the human body)

Each of the levels is formed by an agrupation of the previous level. For example, cells are formed by a number of organelles, and a group of cells form a tissue.

Cells are the basic units of structure of the body, and there are different types of them.

2. Homeostasis

Homeostasis is a process of the body by which the organism works to maintain a stable internal environment, while adjusting to changes in the external environment.

This process is possible because of the work of both the nervous system and the endocrine system. While the first controles the body's activities and detects the necesity of adjustments, the second regulates the activities by using hormones.

1) How many grams of CO are needed with an excess of Fe2O3 to produce 35.0 g Fe?
satela [25.4K]
1. Moles Fe = 209.7 g/ 55.847 g/mol= 3.75 

The ratio between Fe and CO is 2 : 3 

Moles CO = 3.75 x 3 /2 = 5.63 

<span>Mass CO = 5.63 mol x 28.01 g/mol= 157.7 g

2. </span><span />2Na + 2H2O --> 2NaOH + H2<span>atomic weight of sodium is 23             48.7/23 = 2.12 moles  of sodium 
2.12/2 x 24 = 25.44dm^3 hydrogen = 1.06 moles

so multiply it by Avogadro's number1.06 X 6.02x10^23 = 1.204x10^24 molecules of hydrogen
