Answer:
A) With the closer spacing for the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation.
Explanation:
If the space among plants is less, the shadow that they are going to produce is going to reduce the need of water, so they production will rise and the cost to maintain the crops will be less, so the producer can double the profits.
In asexual reproduction, reproductive organs aren't used but they're used.
advantage of sexual- A lot of genetic variation. since they have DNA of two parents. they can survive more and adapt more.
disadvantage of asexual- diversity is limited. Since the organism only gets the DNA of one parent, they wouldn't be able to really survive if something happened.They would easily be extinct.
Sorry I can't really cone up with better words but I hope you get the idea. it all comes down to natural selection really if you've learned about it. Hope it helped!!!
Adenine pairs with thymine (or uracil), and guanine pairs with cytosine.
Answer:
Explanation:
1. Which chamber receives blood from all the body veins?
= Right atrium
2. The blood passes from this chamber into the ...
= Right ventricle
While this is happening, the valve between the right atrium and right ventricle is (open OR closed)
= open
3. The blood in the right ventricle is high in (oxygen OR carbon dioxide)
= carbon dioxide
4. The body (can OR cannot) and low in (oxygen OR carbon dioxide) use this blood.
= cannot
= oxygen
5. Where must this blood go to get a fresh supply of oxygen?
= lungs
Hope this helps!
