Answer:
The Right ventricle and the Left atrium.
Explanation:
The pulmonary circulation loop starts in the right ventricle, where the
deoxygenated blood is. From there, the blood goes through the pulmonary semilunar valves and into the pulmonary trunk. The pulmonary trunk divides into two arteries, the left, and right pulmonary arteries. These arteries conduct the deoxygenated blood to the capillaries in the lungs where we exchange the CO₂ for O₂. Then, the oxygenated blood goes to the pulmonary venules and the pulmonary vein. The pulmonary vein conducts the oxygenated blood from the lungs to the left atrium of the heart. Lastly, the blood goes to the left ventricle, where the systemic circulation starts.
<span>Lungs take in air, and diffuse (absorb) air into the capillaries of the blood. However, this process is two steps, one for inhalation and one for exhalation. Diffusion takes place in both processes, and serves different purposes. One is to absorb oxygen, the other is to rid co2.</span>
I would say B: A bar graph.
definitely not c or d
The right answer is It connects amino acids.
• Amino acids are the building blocks of proteins.
• There are 21 amino acids, but only one type of binding used to connect them: it is the peptide bond.
The peptide bond is formed during the translation step by a covalent bond between an α-amino group of an amino acid and the carboxylic group of another amino acid. A molecule of water is eliminated.
Question: Please use the following information to answer the question(s) below. A group of six students has taken samples of their own cheek cells, purified the DNA, and used a restriction enzyme known to cut at zero, one, or two sites in a particular gene of interest.
Analysis of the data obtained shows that two students each have two fragments, two students each have three fragments, and two students each have one only. What does this demonstrate?
Answer:
"The two students who have two fragments have one restriction site in this region."
Explanation:
A restriction enzyme, restriction endonuclease, or restrictase is an enzyme that cuts DNA into trashes at or close precise appreciation sites inside particles identified as restriction locations. Restriction enzymes are one session of the wider endonuclease collection of enzymes. In the laboratory, restriction enzymes (or restriction endonucleases) are used to cut DNA into minor trashes. The scratches are constantly made at exact nucleotide arrangements. Unlike restriction enzymes recognise and cut diverse DNA sequences.
