Answer:B
Explanation:
WHEN WE RESPIRE THE CO2 EXCHANGES TO 02 IN THE ALEVOLI
Attached is the image of the concerned ECG reading.
In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.
<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>
Answer:
They remain in an environment,even as more competitive species arrive
Explanation:
Pioneer species, in ecological succession, are the first set of organisms to colonize a bare area of land or a disturbed area of land. Pioneer species include lichens, grasses, fungi etc.
Pioneer species have unique characteristics that distinguishes them from every other species of organism. These include:
- They facilitate environmental change, making an environment more habitable for other species.
- They tolerate a wide range of environmental conditions.
- They are capable of colonizing a barren environment, as in primary succession.
However, pioneer species do not remain in an environment, even as more competitive species arrive. They rather give way for new species to emerge and dominate.
Answer:
i think it would be A for wild fire, D for flood and E for Tsunami
Explanation: wild fire are one of the most common ways for a secondary succession that can bring change when the environment is disturbed or damaged. For instance, by allowing fast-growing plants to grow and provide a source of food and shelter for many animals to use and eventually draw them back into the ecosystem. Both flooding and tsunamis help push older organisms and other stuff from the environment to create for room for other plants and animals to come and keep the ecosystem healthy and ongoing.
