the lower surface of the leaf. The most likely explanation for this fact
is that water loss would be less on the shaded lower surface than in
direct sun. </span>
Genetically dominant means that the trait will always be dominant to the genetically recessive trait as long as the allele for that trait is present.
Let's say you have an R allele that codes for a brown coat and an r allele that codes for a white coat. Say the R allele is genetically dominant to the r allele.
If you have an animal with the genotype RR or Rr, it will show a brown coat because the genetically dominant R allele is present.
Only if the animal as a rr genotype will the white coat show because the genetically dominant R allele isn't present.
When you crossbreed, genetic dominance can be important because it can increase the chances you'll have more diverse offspring with increased chance of survival since the dominant traits, if favorable, will always show for a trait.
It is distributed by a blast of energy that happened approximately 13.7 billion years ago. This sudden explosion is known as the Big Bang. This bang created matter. The energy from the explosion blasted the matter throughout the universe. This is explained by Hubble Theory. Edwin Hubble discovered that the universe was moving at an extraordinary pace.

Answer:
The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks.
Explanation:
Remember that physical changes are when you are only changing a physical characteristic of an object. A common example of a physical change would be breaking a piece of wood. Even though the wood is now smaller, and its physical appearance has changed, the wood is still wood.
Sedimentary rocks are formed by compaction, where many rocks are compacted together, and the pressure causes all the rocks to form together into one big rock.
Sedimentary rocks are formed by many different rocks, which means they are still rocks, but they are now compacted together to form one bigger rock. "The formation of sedimentary rocks is indeed a physical change because we are only changing the physical structure of the rock/rocks by compacting them together, they're still rocks."
Hope this helps.
Answer:
Humans have impacted the Colorado river in many ways by, building dams, polluting the rivers, and by using to much of the river's water for themselves.
