Answer: the blue squares are B and the white squares are BB
Answer:
Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.
Explanation:
Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.
Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.
Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.
Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
Because protists have traits that are similar to animals, plants, and fungi. Some protists have a mixture of all three. The three types of protists are Slime Molds, Algae, and Protozoans.

Answer:
DNA sequence from left to right
T G A G G A C T T
Explanation:
There are four DNA nitogenous base they include thymine, guanine, cytosine and Adenine. The Nitrogenous bases are complementary that is Adenine is complementary to thymine and cytosine is completely to quanine and they both can replace each other in this manner A-T,C-G and it means that Adenine can pair with thymine and cytosine can only pair with guanine. DNA is known as Deoxyribonucleic acid. DNA sequencing are shown usually from the 5' end to the 3' end . The sense strand in DNA is used in DNA sequences and also it has the antisense strand and also called the coding strand and the non-coding strand are information are contained in the sequence
