Studies of the similarity of the DNA in wasps and bees suggest that the first bees appeared about 130 million years ago, 50 million years before the first known fossil bee, and probably very shortly after the first flowers evolved in the Cretaceous.
Hi!
The correct options would be B & E.
Rock and granite are hard and tough materials that are allow very minor seepage of water, which is close to negligible which is why these materials have been employed as construction material in buildings.
Clay is relatively more permeable to water as compared to granite and rock, but still does not allow water to flow through easily as it has a low porosity and permeability to water.
Soil & Organic Layer (fertilizer), allow easy passage of water through them due to high porosity.
Hope this helps!
Answer: it could create new species in that same genius like how the pug was selectively bread.
Explanation:
The correct answer is Smooth Endoplasmic reticulum.
Ribosomes are distinct from other organelles as they possess no membrane enveloping them, which differs from other organelles, they comprise of two subunits, and when they are generating some of the proteins they can turn membrane bound to the ER.
The smooth endoplasmic reticulum does not possess ribosomes on its surface and thus does not take part in the formation of proteins. The SER has been found to take part in the synthesis of steroids.
