2) Cross-fertilization makes for more variation in the traits of plants, giving them immunities and resistances to weather, pests, and disease.
Meningocele
Meningocele (MM) is known as meningeal cyst and it is the protrusion
of the membrane that cover the part of spinal cord through the defect in the
vertebral column. Thus, Meningocele (MM) is the least
common fom of spinal bifida and spina bifida is the bony defect in the
vertebral column through the meningeal membrane.
A lemon has no colour, but when one see a lemon, the brain process the information and make one to perceive that the lemon has yellow colour.
The mental process used by the brain to do this is divided into two stages, the first stage is reflection. When light is incident on the lemon, it reflects the light energy into one's eyes, where it is transformed into neural message. The eye is made up of three different cones which are sensitive to different frequencies of light. These cones process the color and the colour perceived by the observer depend on the type of sensitive opponent cells that are stimulated. A yellow color is perceived when the yellow sensitive opponent cells are stimulated.

D
B
Explanation:
1) Reflection is when a ray hits something reflective then bounces back. For example, light reflects off a mirror, which is why you can see yourself in a mirror.
2) Wavelength measures the size of a wave. It is measured from the crest or trough of one wave to the crest or trough of another.
3) Refraction occurs when waves go through different mediums at different speeds. This is why a straw looks bent when in water.
4) Frequency is a way of measuring the speed of a wave. It shows how many waves pass every unit of time.
5) Absorption means that all of the waves were absorbed into the medium and none of them passed through.
