<span>The grouping of organisms based on their common descent is called evolutionary classification. Through evolution, one species has changed and become modified until it became what it is today. However, some of today's organisms have the same predecessor, which is evident if you take evolution into consideration. </span>
Answer:
A. anaerobic respiration in muscle cells, forming lactic acid
Explanation:
Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.
The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.
The answer is the third option. she could still get hypertension if she becomes a heavy smoker because of the chemicals in tobacco can cause your artery walls to narrow increasing blood pressure
Answer:
6.) larger diameter of stomatal pores
A) Increased transpiration pull
1.) thicker film of water on surface of mesophyll cells
2.) higher relative humidity in air around leaf
B) decreases transpiration pull
3.) less curvature of water surface on mesophyll cell walls
4.) lower rate of water evaporation from surface of mesophyll cells.
5.) larger air space in leaf interior
C) has no effect on transpirational pull.
Explanation:
- Transpiration primarily occurs through stomatal openings in the leaves. Increasing the diameter or size of these opening would ultimately increase the amount of water escaping from them and therefore, increase the transpiration rate.
- Higher humidity in the air entails the presence of greater number of water vapours in the atmosphere. Since osmotic pressure plays a major role in transpiration, therefore, this decreases the rate of transpiration.
