Plastics remain in the ocean environment because of their stability and resistance to degradation or biological processing. they do break up into smaller pieces either mechanically or by the action of ultraviolet light (UV).
<span>
The process of polymer (plastic) degradation by light is called photodegradation. Natural degradation of plastic begins with photodegradation, which then leads to thermooxidative degradation. UV provides the activation energy required to initiate the incorporation of O2 atoms into the polymer.</span>
Answer:
The gametes are haploid, having half the number of cells as compared to somatic cells. The gametes or s#x cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
Answer:
The correct answer is - Roots allow plants to obtain water and nutrients, while shoots allow plants to obtain gases and sunlight.
Explanation:
Plants have two major parts of the body normally root and shoot. roots are the parts of plants that usually present under the ground and absorbed the essential nutrients and minerals for the life of the plant. Water is also absorbed by the roots that are used in the various processes such as transpiration and photosynthesis.
The shoot includes stem and leaves and responsible for the exchange of gases, particularly taking in carbon dioxide and removes oxygen with help of stomata. These also absorbs sunlight with help of chlorophyll present on the leaves.
The correct answer should be something like: "Gene therapy involves the use of bacteria or viruses to deliver new or modified genes to cells". That is what can be concluded based on the paragraph you provided.
