Answer:
trend toward a sporophyte-dominated life cycle
the trend toward larger gametophytes
Explanation:
<em>The major trend in the evolution of land plants is the domination of the sporophytic phase in the life cycle and alternation of generation. It also moves towards a larger gametophytes</em>
In lower plants, the gameophyte phase was dominant in the life cycle while in bryophyte, both gametophyte and sporophyte phase are co-dependent.
The sporophyte phase is the diploid phase while the gametophyte phase is the haploid phase.
Also, the gameotyptic stages are quite microscopic (usually in the form of spores) in lower plants while they become bigger in land plants (in the form of ovary and pollen) although with fewer cells.
Answer: a. begins to accumulate significantly at a point that is about 55-65% of Vo2 max
Explanation:
Lactate is produced in the body after the burning of glucose (glycolysis), to supply energy without the presence of oxygen (lactic anaerobic metabolism). In long-term physical activities, oxygen supply is not always sufficient. The organism seeks this energy in alternative sources, producing lactate. For the average human, blood lactate begins to accumulate significantly at a point that is about 55-65% of Vo2 max. The accumulation of this substance in the muscles can generate a hyperacidity, which causes pain and discomfort soon after exercise. Thus, the determination of lactate blood concentration allows indirect evaluation of the metabolic acidosis of the exercise, being one of the diagnostic tools used by Exercise Physiology.
