Answer:
False
Explanation:
Ground beef labeled 75% lean could be a good choice, but that is because it contains only 25% fat, not 25% of its calories come from fat.
Answer:
From the energy stored in food substance( glucose) as Chemical energy to the energy of motion,which is Kinetic energy.
Explanation:
The energy is produced in the mitochondria which are packed in the flagellum of the a sperm cells.Thus as the sperms move the these flagella flips back and forth,Energy inform of ATPs are generated from the glucose(chemical energy) during cellular respiration in the mitochondria, this energy is converted to Kinetic energy for motility.
Specifically,ATP production for the sperm cells is initiated by Glycolysis. This is because the environments where it swims to meet the ovum punctuates with in oxygen, besides,Glycolysis can occur with or without oxygen.
Sperm motility is very important to male fertility.
The question that most likely relates to the ecologist's observations and collected data is, 'Are fish dying due to reduced oxygen in the water?'
<h3>Research questions</h3>
Research questions are usually coined from observations. Observation is the first step in the scientific method. Once the research questions have been formed, hypotheses follow.
In this case, the ecologist, who happens to be the researcher in this case, observed that fishes were dying in large numbers. Fortunately for the researcher, he also observed that the lakes around the city where fishes were dying had significant algae growth as well as reduced oxygen levels.
The right questions to ask, therefore, should try and relate to observations together.
Thus, linking the death of the fishes to reduced oxygen levels in the lakes is the right question to ask.
