no its not its not a statment
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells
Answer: Photosynthesis is the process of when a plant makes it's own food, and the main goal is to convert solar energy to chemical energy.
Explanation: Plants use photosynthesis by taking the sunlight, to synthesize foods from carbon dioxide and water. Since plants can't move and consume other organisms, they use photosynthesis. The formula is: 
.
Like I said, the main goal is converting solar energy to chemical energy then store the chemical energy for future use, for example it can be used for Chemical batteries, Natural gas, Heat, Food, etc.
B. a specific place on a chromosome where a particular gene resides.
A locus (plural loci) in genetics is the position of a gene on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 19,000-20,000, on the 23 different chromosomes. A variant of the similar DNA sequence located at a given locus is called an allele.
Answer:
If a person has extra chromosome you or they might have down syndrome
Explanation:
Normally a baby inherits 23 chromosome from each parent which is equal to 46 total and basically those who survive develop down syndrome
