The energy source of the sperm for them to swim is the protein breakdown by mitochondria in the midpiece of the sperm.
Mitochondria are double membrane-bound organelles found in the cells. It is said to be the "powerhouse of the cell". They provide ATP as a source of chemical energy for the cells.
The answer is lag. The number of bacterial cells doubles at a constant, exponential rate during log phase, while growth rate and death rate are the same during stationary phase. The fourth phase is the death phase, when the rate of cell death is faster than the population growth.
Varies
Explanation:
From the differences in the width of the alternating stripes, we can conclude that the lengths of time represented by this evidence varies.
Normal and reversed polarity do not have equal length of time when they occur.
- The paleomagnetic field just like the earths geomagnetic field we have today varies from time to time.
- During period of normal polarity, the north pole of the geomagnetic field is close to that of the earth.
- At reversed polarity, the north of the magnet changes position.
- Their is no regular interval to this
- Magma that are getting magnetized during this period will have different variations in the width of the magnetic fields.
- The width of the stripe shows the duration of the anomaly.
- Since the geomagnetic field takes their root from the core, the intensity varies and it affects the extent of magnetization of magnetic minerals in rocks.

Answer:
. Experimentation is the heart of science. Scientists ask questions, gather evidence, share ideas, and analyze data. In designing an experiment, the specific question (or questions) that the experiment is meant to answer must first be clearly identified.
