So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds. When you see the flash of a lightning bolt, you can start counting seconds and then divide to see how far away the lightning struck.

10. what is the probability of a yellow (Y) and wrinkled pea (r) will appear from a cross of Yyrr x YyRr?
Oliga [24]

Answer:

D

Explanation:

The punnett square showing the cross Yyrr x YyRr is attached

The gametes that the Yyrr individual can produce are either Yr or yr. The yyRr individual can produce YR, Yr, yR, or yr. The possible genotypes are shown in the punnett square.

For a pea to be yellow and wrinkled, it would have the genotype YYrr, or Yyrr (as yellow is dominant (Y) and wrinkled is recessive (r)). Therefore, we count the number of those genotypes of the total genotypes we get.

There are 4/8 that are either Yyrr or YYrr, so the answer is d.

What is meant by suggesting that Earth's oceans are connected?
Katen [24]
C seems like the answer because at the end of South America, there's nothing blocking the two oceans there from connecting. All of the oceans are connected together. They're just different because of where they are and the conditions of that area of earth.

I dont' think water flows under the continents either so D doesn't sound right at all. A is just beyond logical because there's no way that has anything to do with how the oceans are connected to each other. B MAY be the answer but I'm leaning more towards C.

Answer: The correct answer is D

Explanation: Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. ... At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
