Answer:
Cork is a protective tissue that separates the living cells of the plant from the outside environment. The formation of cork in the periderm is the result of the activity of a secondary meristem, the cork cambium, or phellogen.
Explanation:
The way that you could use molecular biology to determine whether these birds have evolved from a shared common ancestor is to take a look at their proteins, RNA, and DNA. Because the more similar these things are in the two types of birds, the more possible it is that they are somewhat connected via a common ancestor.
Yes, this is correct!
Let's imagine two systems, one with 50 species and one with 4000. Both of them experience a draught and as a result 25 species of the first one die (that's quite likely) and 800 of the second population die out (more would not be very likely).
So the first one lost 50% of species and the second one 20% - that means that the second one, with greater biodiversity has a bigger stability:)
1: over population
2:disease
3: Darwinism.
