Coniferophyta

Explanation:

Plants and trees belonging to coniferphyta are gymnosperms which are vascular plants with unprotected or naked seeds. These are called conifers because they bear male and female cones produced by the sporophytes on the same tree . The female conifers have many seeds on the cone scales.

These cones have spores which undergoes meiosis and produce male and female gametes respectively. Male gametes with pollen grains produces sperm cells and female gametes produce egg cells inside the ovules.

During the spring season with winds blowing, pollen released from the male cone disperses on the female cone present on the same tree.

Upon reaching the female cone, the sperms in the male gametes will fertilize the egg cells in the female and will fertilize to form zygote. This zygote will develop into an embryo in the ovules and later develop into seeds.

When these seeds fall on the ground, they get germinated into a new conifer. Thus dispersal of the seeds is taken care of by the seeds itself without the production of any fruit.

What kind of waves are present during an earthquake? ...
Aleksandr [31]

Answer:

1.The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.

2. As the combustible materials burn, some of the chemical energy is transformed into heat energy, and some is transformed into light energy. Light energy, also known as radiation or electromagnetic energy, is a type of kinetic energy that takes the form of visible light waves, such as the light from a match

3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

4. Answer: Refraction is the bending of light (it also happens with sound, water, and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms, and rainbows. Explanation: Refraction.

5. The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
