Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.
<h3>Answer:</h3>
Jean has a sample of a liquid. If she changes the liquid's phase by <u>Evaporating</u> it, the molecules will spread out, allowing the sample to expand and fill a container of any shape or volume.
<h3>Explanation:</h3>
Evaporation is a kind of condensation that happens on the surface of a liquid as it turns into the gas state before approaching its boiling point. The enclosing gas must not be immersed with the evaporating matter. Evaporation is a major element of the water cycle and is continually happening throughout the environment.
The lungs are considered to be an organ.
