Answer:
An organism would need a 4 chambered heart.
Explanation:
The heart consists of 4 chambers in which blood flows freely. Right atrium, left atrium, left ventricle and right ventricle.
The pulmonary arteries carry de-oxygenated blood to the lungs from where CO2 is released and O2 is picked up during the process of respiration. The pulmonary vein then takes the oxygenated blood to the left atrium of the heart and then to the left ventricle of the heart.
Answer:
1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases
2) To hold the genetic info for the cell
3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus
4) To bring amino acids to the ribosomes to help build a protein
5) A chain of amino acids held together by peptide bonds
6) Ribosomes
7) Because those are the bases that are complementary in DNA so they must be equal
8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made
9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
Answer:
A solid that forms from solution during a chemical reaction is called a precipitate.
