Vegetative Propagation.
Vegetative propagation is technique through which plants reproduction takes place in an asexual way. This is usually done by cutting a stem of a plant and to reproduce another plant from the existing one. This can also be done via sexual means.
The advantages of growing of fruits and vegetables by using vegetative propagation are many. The biggest benefit is if we have a plant of a desirable trait, that same plant can be used again and again to reproduce fruits and vegetables. Vegetative propagation is also treated as cloning method.
Answer:
Paleozoic
Explanation:
The first insect fossils are dated to the Devonian, but because of the development of the genetics, the scientists have been able to trace the appearance of the first insects in the Ordovician. The insects originated from the crustaceans. Initially they were walking on land, but they hadn't developed wings. The wings came to develop in some insects in the Devonian, and since than it has gradually became one of their trademark features. It is interesting that the first insects actually appeared at the same time with the first terrestrial plants, and also that they are the first organisms to develop wings and be able to fly.
Answer:The pressure of Mercury = 588,600Pa
Explanation:
The pressure of Mercury is given as
p=h x ρ x g
Where h =height= 20 dm
changing to meters
10 decimeters (dm) =1 meter
20dm =2 meter, 2m
ρ is the density =30000-kg/m³
g , gravity = 9.81-m/s²
Pressure = 2.0m x 30000-kg/m³ x 9.81-m/s²
588,600 kg.m/ s²/m² =588,600 N/m²
The pressure of Mercury=588,600Pa
Wind which is caused by uneven heating.
