Also , Wheat Plant have Fibrous Root System .
Kidney beans is a Dicotyledon Plant .
So , The leaves of Kidney Beans Plant have Reticulate Venation .
Also , Kidney Beans Plant have Taproot System .

Look at the image of a mountain goat and a goat found in the plains. Point out the similarities and differences between them. What are the reasons for these differences?
They have long , thick fur coat to protect it from cold .

Strong legs adapted for climbing steep and rocky surfaces .
They have short fur as plains are warmer .
Coat may be brown , black , or white for camouflage in plain areas .
Legs are not as strong for climbing but suited for walking on flat land .

As the population grows and people want more comfortable lives, forests are being cut down to meet various needs. How can this affect our surroundings? How do you think we can address this challenge?
Trees are cut
No food for herbivores
( Elephants , Deers , Etc )
No food for carnivores
( Lion , Tigers , Etc )
Population of both plants
and animals decrease
Loss of biodiversity of area
How to address the challenge ?
