Explanation:
During a stimulus, there is an influx of Na+ ions into the cells. This causes the inside of the cell to develop a more positive charge compared to outside the cell. So, the cell attains a more positive charge when it is stimulated.

Answer:
E) In both mosses and ferns, moisture is required for sperm to reach the egg. In mosses, gametophyte is the dominant stage of the life cycle. In ferns, the sporophyte is the dominant stage of the life cycle.
Explanation:
The *sporophyte of fern plant is dominant over the smaller and nutritionally independent gametophyte*. The sporophytes are photosynthetic, long-lived and highly branched. *Sperm cells of fern possess whip-like flagella in their cell walls that enable moisture swim to reach the egg*
*In Mosses,the gametophyte is more prominent (dominant)* just like in lower plants. These organisms *require external water(moisture) in the form of dew or rain to move their sperm during fertilization*.
Therefore, *In ferns, the sporophyte is dominant over the gametophyte*, while *in mosses,gamatophyte is dominant over the sporophyte.* Both require moisture for sperm to reach egg.
.Answer:
1. s-waves
2. s-waves
3. p-waves
4. p-waves
5.surface waves
Explanation:
- A<em> </em><u><em>P-wave</em></u> is one of the two main types of elastic body waves, called seismic waves in seismology. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph. P-waves may be transmitted through gases, liquids, or solids.
- a <u><em>surface wave</em></u><em> </em>is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities
- <u><em>S-waves</em></u>, secondary waves, or shear waves (sometimes called an elastic S-wave) are a type of elastic wave and are one of the two main types of elastic body waves, so named because they move through the body of an object, unlike surface waves.

Lysozyme which is found in the lysosomes. They function at a relatively low pH and are so because if they functioned at physiological pH they would digest the cell. But in this case, they are in the lysosomes where they are safe and at a lower pH so when the vesicles open they can emit hydrogen ions and the lysozyme to digest the foreign material.
