Explanation:
No tilling farming is a type of agricultural practice where new crops are grown without spreading the soil through the tillage. This is a very age old practice used by farmers to replant new crops.
The advantages of using thus technique are many. It helps to kill hundreds of insects, it also helps in protecting the soil by leaving crop residue, apart from this is increases the irrigation productivity. Which is why farmers prefer no tilling agriculture mainly because the long term benefits of this technique are many.
Divergent evolution is when two different species share the same ancestral origins but have evolved differently whereas convergent evolution is when species with different ancestral origins have developed similar features.
In convergent evolution, two species that are not necessarily closely related develop similar features often as a result of adaptation to similar conditions.
An enzyme lowers the activation energy of a reaction so it can take place within living organism, so an enzyme is a biological catalyst.
<span>Bone marrow which is located <span>within the spongy or cancellous portions of bones is the essential site of new blood cell production or hematopoiesis. Bone marrow contains stem cells which able to differentiate into specialized cell types. People with diseases like blood cancers, such as leukaemia and lymphoma, sickle cell anaemia, and other rely on bone marrow transplantation to survive.</span></span>
1) The process arrow A represents is photosynthesis.
2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.
3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.
I hope this makes sense. Hope this helps! :)
