The Andean countries have landforms such as mountain peaks, plateaus, and depressions.
Explanation:
The Andean countries are mostly located on the Andean Mountain Range. This is one of the largest mountain ranges in the world, stretching across all of South America, more specifically on its western side, in a north-south direction. This mountain range has created lot of high mountain peaks. There are also numerous plateaus of varying sizes, as well as lot of intermediate depressions.
- These mountains have formed as a result of the subduction zone between the South Americana and Nazca plates.
- There are high peaks on this mountain range across all of its stretching.
- The mountain range is divided into numerous sections, all of which are sharply divided by large depressions.
- There are also lot of plateaus on the Andes, big portion of which have been used for creation of large human settlements.

It's caused by blood pooling in the legs, so there's insufficient return to the heart and brain. Normally, moving one's legs helps to pump blood back to the heart through muscle contraction. Locking the knees makes standing still easier, but reduces use of the leg muscles. In some people, this pooling may lead to hypoperfusion of the brain and fainting, which is essentially the body's way of putting the brain and the legs and the heart at the same level.
If there is an increase in coronavirus that means that the animals that eat the producers will be less which causes more producers
Answer:
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
Explanation:
In laborador retrievers, pigment color is influenced by two genes. Gene A determines the type of pigment produced and gene B affects whether the pigment gets deposited in the hair shaft. If two heterozygous black laborator retrievers were crossed and offspring were produced in a ratio of 9 black dogs to 3 brown dogs to 4 yellow dogs, what are the genotypes of the offspring?
Gene A determines colored pigment.
Gene B ensures that the colored pigment is deposited.
Two heterozygous black laborador retrievers were crossed.
AaBb x AaBb
Progeny
9 A_B_
3 A_bb
3 aaB_
1 aabb
<em>Since there were 9 black, 3 brown and 4 yellow dogs, the possible genotype of the different colors are: </em>
Black dogs = A_B_
Brown dogs = aaB_
Yellow dogs = A_bb and aabb
