Answer:
The boundary between two air masses that have different temperatures or humidity. In the mid-latitude areas of the Earth, where warm tropical air meets cooler polar air, the systems of fronts define the weather and often cause precipitation to form.
Explanation:
Scientific definition for front
Answer:
Cell cycle regulators are the cell cycle only when they are tight bound to CDKS.
Explanation:
To be fully active, the CDK/Cyclin complex must also be phosphorylated in specific locations. Like all kinases, CDKS are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.
Should be 50%
male genes: Gg
female genes: GG
Scientists use the light year because nothing can travel fast than light. Therefore, in any given time frame, light will travel farther than any other substance or particle in the universe. For more precise measurements, scientists use astronomical units. One AU is equal to the distance between the earth and the sun. For anything less, scientists usually use kilometers. For extremely large, interstellar distances, light years are very useful. You wouldn’t want to measure the distance between Earth and Proxima Centauri in kilometers or even AU. The lightyear gives a simple, relative measurement.
