Answer:
E. 3, 6, 7, 4, 5, 8, 1, 2
Explanation:
Systemic circulation is the circulatory pathway which is involved in the transport of the oxygenated blood to the body when pumped by the heart through arteries, capillaries and then back to the heart.
In the given question, the order of vessels in the systemic circulation has been asked which begins with the entry of the deoxygenated blood to the heart.
1. The deoxygenated blood enters the blood from vena cava to the right ventricle.
2. From the right ventricle, the blood enters the right atrium which pumps the de-oxygenated blood to the lungs through an artery called the pulmonary artery.
3. In the lungs, the blood becomes oxygen rich and is returned to the left atrium through the pulmonary vein.
4. The blood then enters the left atrium which is then pumped to the body through the main artery called the aorta.
This completes the systemic circulation and thus, Option-E is correct.
Answer:
Carrying capacity is defined a the ability of the natural ecosystem to take care of the environment which does not necessarily cause the resistance in population increase.
Explanation:
The earth indeed has a mechanism of delivering changes to the system and keeping it intact but as the case of the rapid growth of population arises the mother nature sees this as an exponent of unsustainable growth as the resource used to sustain large populations is no longer available or are exhausted.
A population increase so does the carrying capacity and workload of the natural environment which at the time gets slow due either due to the man's artificial technology or the natural process like hurricane or earthquake itself.
But seeing the nature as providing possibilities for the existence of the societies throughout ages and hence trying to maintain its originality may break those activities that it considers resistance as several biotic factors like predators, disease, competition, and lack of food.
A biotic factor is all of the students in the classroom.
Hope this helps!!
If the temperature is too low, enzyme molecules don’t have enough kinetic energy to collide and combine with other substrate molecules. So the enzyme activity/ reaction rate will be very low. The rate will rise again once the temperature increases to its optimum temperature.
But if the temperature is too high, enzyme will be denatured, which means the shape of the active site of the enzyme is changed. It can no long combine with other substrate molecules. The rate will drop significantly. Yet, lowering the temperature won’t help because denaturation is permanent and irreversible.
All living things are made of cells. Within cells, there are tiny working parts called organelles. They each have a different job in the cell. A centriole is an organelle that helps cells divide, or make copies of themselves......
Centrioles are made of nine triplets of microtubules arranged in a cylinder.
