DNA is like a blueprint telling enzymes and acids like RNA and mRNA what to do with its "code." The first option is not correct because the situation is actually vice versa. Chromosomes are made up of DNA and proteins; DNA is not made up of chromosomes and proteins. There are 23 pairs of chromosomes in the human cell. In that cell there is also DNA and ribosomes that make up proteins. Option three is not entirely true because, well, if the option is referring to the process of transcription, then it is mRNA that translated DNA's code not RNA's. The fourth option is also wrong because alleles are located in parts of chromosomes. Thus, the second option is the correct option because the option both makes sense and is what DNA contains.
Answer:
The probability is 99.99%
Explanation:
Because the probability that the DNA of a random person matches the DNA of the crime scene is 1/10000, that is 0.01%, then the probability that Kevin is guilty after the test is 9999/10000, that is, 99.99%.
Answer:
Billiard Ball Model
Explanation:
I used process of elimination.
The plum pudding model looks more like chocolate chip ice cream scoop.
As you can probably tell, that is not a solar system model.
It also is not a nuclear model because those look more like the attached file.
Answer:
Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles.
Answer:
Answered below
Explanation:
In the 1920s, Russian Chemist A.I Oparan and English geneticist Haldane, first conceived and developed independently, the theory of Primordial soup. The primordial soup theory suggests that life began in a pond or ocean as a result of the combination of the right amounts of chemicals from the atmosphere and some form of energy, under the right conditions, which resulted in the production of amino acids, the building blocks of proteins from which life evolved. This is suggested to have happened 3 to 4 billion years ago.
This theory was tested by Chemist Stanley Miller and Physicist Harold Urey, in 1950. They mixed gases thought to be present in the primitive earth and electrically sparked the mixture, which resulted in the formation of amino acids.
