As scientists have developed more productive crop varieties, farmers have switched from growing many traditional varieties to ne

w high-yield varieties. For example, in Peru, the Indians once grew 500 native varieties of potatoes. That number has been reduced to about twenty major potato varieties, worldwide.

Switching from traditional crop varieties to new high-yielding varieties of potatoes will lead to a <u>reduction</u> in the<u> </u><u>varieties of potato</u><u> </u>as well as the <u>potato</u><u> </u><u>gene pool</u><u>.</u>  

Explanation:

This switching led to the green revolution in many countries with increased production of crops. However, the traditional healthier varieties of crops are lost over the period and only the newer high-yielding varieties remain. When the genetic pool of a crop is downsized it leads to declining of the genetic diversity.  

A large gene pool will help to maintain the genetic diversity of a species to withstand environmental challenges and stresses. Smaller a gene pool becomes, greater are the chances for it become wiped out or extinct.  

Hence to maintain the gene pool of a crop and the genetic diversity, traditional varieties should be maintained.

During a choking episode, most foreign objects are more likely to become lodged in the ________ bronchus due to its larger diame
yKpoI14uk [10]
There are choices for this question namely:

<span>right primary
right secondary
left secondary
left primary
</span>
The correct answer is "right primary" or the right main bronchus. Anatomically, the right main bronchus has a larger diameter and a steeper angle (to compensate for the location of the liver). When a foreign body is accidentally aspirated, most commonly, it will lodge on the right main bronchus; especially in children.

vesna_86 [32]
Auxin is used to stimulate plant growth which occurs at the roots and shoots of plants. you must have heard that plant growth is apical therefore it helps for apical dominance. <span>Apical dominance is the phenomenon whereby the main, central stem of the plant is dominant over (i.e., grows more strongly than) other side stems; on a branch the main stem of the branch is further dominant over its own side branchlets that is the shoot has more control over the lateral bud growth.</span>
