Answer:
The sporangium matures and releases spores into the air. There are about 30,000 species of ascomycetes, members of the division ascomycota, commonly called sac fungi. The most well known members of this group, yeasts, are used to make bread rise and to carry out anaerobic fermentation in brewing alcohol.Apr 17, 2006

Explanation:
Gregor Mendel developed the model of heredity that now bears his name by experiments on various charactersitics of pea plants: height (tall vs. Short); seed color (yellow vs. Green); seat coat (smooth vs. wrinkled), etc. The following explanation uses the tall/short trait. The other traits Mendel studied can be substituted for tall and short.
Mendel started out with plants that "bred true". That is, when tall plants were self-pollinated (or cross-pollinated with others like them), plants in following generations were all tall; when the short plants were self-pollinated (or cross- pollinated with others like them) the plants in following generations were all short.
Mendel found that if true breeding Tall [T] plants are crossed (bred) with true breeding short [t] plants, all the next generation of plants, called F1, are all tall.
Next, he showed that self-pollinated F1 plants (or cross- pollinated with other F1 plants) produce an F2 generation with 3/4 of the plants tall and 1/4 short.
A. 1/4 of the F2 generation are short plants, which produce only short plants in the F3 generation, if they are self- pollinated (or crossed with other short F2 plants;) these F2 plants breed true.
B, 1/4 of the F2 generation (1/3 of the tall plants) are tall plants that produce only tall plants in the F3 generation, if they are self-pollinated; these tall F2 plants breed true.
C. 1/2 of the F2 generation (2/3 of the tall plants) are tall plants that produce 1/4 short plants and 3/4 tall plants in the next [F3] generation, if they are self-pollinated. This is the same proportion of tall to short that F1 plants produce.

The answer is; right atrium, pulmonary arteries, pulmonary veins, left ventricle, aorta
Deoxygenated blood from the tissues flows into the heart through the vena cava vein. The blood is pumped by the right ventricle to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs and flows back to the heart through the pulmonary vein. The heart (left ventricle) then pumps the oxygenated blood to tissues through the aorta.
