Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
It's basically a wave that moves back and forth at regular speed through matter. because of that it transfers energy through a medium (matter). however the movement of the wave is limited because of this but it can still move over long distances. so because of this these types of waves don't move far from their original point or Equilibrium position. in short think of throwing a pebble into water and seeing the little ripples from it, that's a mechanical wave.
Answer: phosphates absorbed by plant roots
Explanation:
The inorganic phosphate ions are available in the rocks which are distributed into the soil by the withering process. The aquatic plants absorb the phosphate ions through their roots. The plants are consumed by the animals. The inorganic phosphate is converted by the plants and animals into organic form incorporated in the DNA.
Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
In most animal life cycles, the multicellular diploid stage is the dominant ploidy.
The multicellular diploid stage is the most obvious life stage in the diploid-dominant life cycle, as it is in most animals, including humans. Almost all animals follow a diploid-dominant life cycle strategy in which the organism's only haploid cells are gametes. Almost all animals have a diploid-dominant life cycle, with the gametes being the only haploid cells. The gonads produce special diploid cells known as germ cells early in the development of an animal embryo. During the sporophyte phase, a diploid (two-chromosome) plant body grows and eventually produces spores via meiosis.
