Answer:
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The roots absorb water and minerals from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the Sun and make food for the plant, using an amazing process called photosynthesis.
Explanation:
Hershey and chase have concluded that DNA is not protein it was the genetic material.
Explanation:
Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.
The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.
The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division. There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis.[1][2][3] Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
Calvin Bridges and Thomas Hunt Morgan are credited with discovering nondisjunction in Drosophila melanogaster sex chromosomes in the spring of 1910, while working in the Zoological Laboratory of Columbia University.[4]
