A concentration.
In cells, there are two types of transportation of needed organic compounds. The active and passive transport.
The active transport requires energy or ATP while passive doesn't. Further, diffusion, a passive transport transfers compounds from higher to lower concentrations.
Answer: Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

Answer:
Water / 
Explanation:
Energy that is released from glucose during respiration but not transferred to ATP bonds can be detected as 
Answer: A). 2.7 million people per year
Explanation:
From 2000 to 2010 is 10 years. Change in population in 10 years = population at the beginning of 2010 minus the population at the beginning of 2000. This is:
309 million -282 million = 27 million.
Therefore average change in population person year = 27 million/10 = 2.7 million per year
Answer:
The correct answer will be-
1. Chromosomes are made up of protein and nucleic acid.
2. Genes are located on chromosomes.
3. Chromosomes are found in the nucleus.
Explanation:
Watson and Crick are known for their findings on the structure of DNA in 1953. Their findings were motivated by the book called "What is Life?".
The book stated the concepts which were well accepted by the scientific communities that is the gene determines the trait which is located on the chromosomes proved by the experiments of Morgan.
The chromosomes are the condensed structure present in the nucleus was suggested by the Nageli in 1884. The chromosomes are composed of nucleic acid and protein was also proved and was well-accepted fact.
But the genes are made up of DNA was not well accepted which was suggested by the experiments of Avery in 1940s.
Thus, the selected options are the correct answer.
