Light-independent reactions are the second stage of photosynthesis. They make sugars. Light-independent takes place in the stroma and doesn't require light. They need carbon dioxide (CO2) from the atmosphere to build the sugars. These sugars are used to build starches and cellulose in a cycle of chemical reactions.
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
D. Coal is naturally made and cannot be renewed by humans.
Through a cut or an injury where any skin has been broken.
An infection through an animal's bite or sting.(Like the West Nile Virus which spreads though mosquito bite, or Rabies though an infected mammal's bite).
Can be inhaled or consumed and go from the lungs into the other organs causing harm internally.
