Tachycardia is a condition when the heart rate is greater than 100 beats per min at rest. The electrocardiogram is a diagnostic tool that measures and records the electrical activity of the heart. Bradycardia on the other hand is when the heart rate is slower than normal. The Tachycardia and bradycardia can arise from either the SA node or from other areas of the cardiac.
Answer:
All the statements are true except the second i. e. the soil quality in an ecosystem Does not matter as much as soil quantity.
Explanation:
In an ecosystem both quality and quantity of water is very important. If the quality of water is not suitable, that it contains polluted substances so the health of the organism such as fishes and other aquatic animals will adversely affected and sometimes dealth occurs and the ecosystem will be negatively affected.
Answer:
C. Amoebae and paramecia is the answer.
Explanation:
A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.
<u>Explanation:</u>
With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.
If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.
