3. Expiration of air from the lungs is a mostly passive process not requiring muscle action.

True or False?


4. Oxygen is transported around the cardiovascular system by dissolving within the blood.

True or False?

Answers

Answer 1

Answer:

False and true (i'm not sure fully)

Explain:    

(False) Expiration is usually a passive mechanism that occurs when the diaphragm muscle relaxes (that contracted during inspiration). The elastic recoil of the lungs is the primary cause for passive expiration.(True)Despite the fact that oxygen dissolves in the blood, only a small amount is transferred this way.

         Inside the air sacs, oxygen flows through paper-thin walls to tiny blood vessels known as capillaries, where it is absorbed into the blood. The oxygen is then transported throughout your body by a protein called haemoglobin, which is found in red blood cells.

hope this helps!!!

Answer:

The liquid produced when making yogurt.

Explanation:

Whey is the liquid produced when making yogurt. It is typically an end or by product gotten during the Greek yoghurt production through centrifugation or straining and it is usually two-thirds (⅔) of the milk used. Also, it's acidic in nature and yellowish in colour.

Whey can be used by farmers to feed livestock and added to the soil as fertilizers in order to increase the nutrient level of the soil, as well as boosting crop production.

..Self-worth, you need to know that you deserve the best. Do not let anyone treat you like you are average. You get what you settle for, so aim high and surround yourself with those who see your self-worth, who love you, who respect you, who encourage you and build you up to a higher level. You are special, and you can achieve anything, remember that.
“Your value doesn’t decrease based on someone’s inability to see your worth.”
“Make sure you don’t start seeing yourself through the eyes of those who don’t value you. Know your worth even if they don’t.”
“If you find yourself constantly trying to prove your worth to someone, you have already forgotten your value.”
“Listen to the right people and ignore the wrong ones. People that doubt you, hate you and judge you are never worth your time or attention.”
“To be beautiful means to be yourself. You don’t need to be accepted by others. You need to accept yourself.”“If I could give you one gift, I would give you the ability to see yourself as I see you, so you could see how truly special you are.”

Compared to fats in meat, vegetable fats contain more?

Answers

Answer:

Animal Meat is Monounsaturated Fat, Meaning that it is more resistant to heat and longer lasting because of the Single Carbon-Carbon bonds, However the Vegetable Fat is Polyunsaturated Fat, Meaning that it is more susceptible to toxins because of it's one or more Double Carbon-Carbon bonds, Making it Unsaturated

Vegetable fats contain more unsaturated fatty acids than fats in meat.

Unsaturated fats are the better type of fats so to speak because they have benefits such as:

they lower cholesterol levels they help with heart rate stabilization and, they ease inflammation in the body

Vegetable fat have more of these fatty acids than animal fats which is why people are generally advised to eat less meat and more vegetables.

5. K+

6. Na+

7. into

8. Ca+

Explanation:

Pacemaker cells (also known as sinoatrial node cells) are cells that generate rhythmic impulses and set the pace for blood pumping in the heart. These cells have the ability to rhythmically depolarize and initiate action potentials. In pacemaker cells, Ca2+  and Na+ levels are higher in the extracellular environment, while K+ concentration is higher intracellularly. The pacemaker action potentials have three phases: 1-depolarization, where membrane potential reaches -40 mV and voltage-gated Ca2+ channels open, 2-repolarization, where voltage-gated Ca2+ channels close and voltage-gated K+ channels open, and finally 3-gradual depolarization, which is caused by the slow influx of Na+ ions.
