Answer:
Sound travels as waves of energy, but, unlike light, the waves transmit energy by ... You can think of it like a tiny air explosion that travels outward around the thing ... If you drop a marble into a bucket of water, you will be able to see the ripples ... it sounds funny because the water is carrying the sound wave instead of air.
Explanation:
Plants reproduce through the
process of fertilisation. Fertilisation is the process where female and male
cells join together to form an embryo inside the seed. The seed protects the
embryo in preparation for germination when conditions permit the plant to
produce new plants.
Seed plants are classified into
two types to determine reproduction. First are the Angiosperms, this type of
seed plant has flowers that have special structures for reproduction. Pollens
are made by male cells, while ovules are made by female cells. Pollens are carried
out through the process of pollination (e.g. wind blows, insects carrying
pollen). Most angiosperms that don’t undergo pollination develop intro fruits.
If it goes into pollination they become new flowering plants.

Second classification is the
Gymnosperms, which are seed plants that are held in cones. Gymnosperms like
Angiosperms also have male and female reproductive cells. Reproduction also
occurs through pollination but most gymnosperms are trees. The best example of
a gymnosperm are pine cones. </span>
Answer:
<u>Uranium</u> is the inner transition metals is critical to the nuclear power industry.
Explanation:
Uranium is a common transition metal found in rocks and is used for nuclear fission reactions. In a nuclear fission reaction, a neutron atom is hit on a uranium atom. As a result, the uranium atoms breaks down releasing huge amounts of energy. Also, more neutrons are released by the breakdown and hence the this neutron hits other uranium atoms and the cycle continues. The most active radioisotope of uranium being used in nuclear fission reactions is U-235.
