Answer:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

Explanation:
Tidal power can be harnesed and be used to drive turbines which are used in hydroelectric power stations. Tide involves the movement of water from one place to another and this results in ocean currents. The tides carry a huge amount of renewable energy in them.
Wave power: waves accompany tides. These waves can be easily harnessed to drive wind turbines which in turn produces electricity. They can also be used in wind mills.
Power from fossil fuels: Oceans contain a vast reserve of fossil fuels. Most oceans in times past are sedimentary basins that accumulates remain of organisms. As natural processes plays out, they yield fossil fuels. These fossil fuels can be tapped for use in different machines and gas power plants.

Explanation:
For fertilization to occur in angiosperms, pollen has to be transferred to the stigma of a flower: a process known as pollination. Gymnosperm pollination involves the transfer of pollen from a male cone to a female cone.
Answer:
The correct answer is -
nucleus - reproduction, mitochondria- reproduction, golgi apparatus - waste production, endoplasmic reticulum - growth, ribosomes - growth, lysosomes- waste production, vacuoles - growth, cell membrane - interaction with the environment, chloroplast - uses energy, cell wall - interaction with the environment
Explanation:
A Cell has various organelles with more than one generic function such as the nucleus not just play role in cell reproduction but also plays role in regulating other organelle and cell growth by transcription. Mitochondria produces and provides energy for many functions such as growth, reproduction and substance transport.
Golgi apparatus package proteins and wastes to transfer them out of the cell. The ndoplasmic reticulum modifies the protein produced by ribosomes and helps in growth of the cell. Lysosomes digest waste and cell debris by lysosomal vesicles. Cell membrane and cell wall interact with outer environement.
