<span>Superior and inferior vena cava enters the right atrium which is pumped by the tricuspid valve to the right ventricle and to the pulmonary valve to the pulmonary artery then to the lungs from the lungs back thru the pulmonary veins entering the left atrium pumped by the mitral valve to the left ventricle to the aortic valve to the aorta.
The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.</span>
Answer:
The time to make the product will be reduced.
Explanation:
Enzymes are substances that acts as biological catalysts and speed up the rate at which a chemical reaction occurs by lowering the activation energy of the reaction. The activation energy is the energy required for the chemical reaction to occur.
Hence, when making a product of size 1mg, the presence of an ENZYME will reduce the amount of time required for the products to form i.e. the reaction will be sped up.
Plant cells have a cell wall and large central vacoule, and chloroplasts that animal cells do not.
Answer:
DNA is copied and transcribed into another form. This smaller segment is made of <em><u>genes.</u></em>
Explanation:
Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).
Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.
