Answer:
Evolution.
Explanation:
The ground finch could not survive after the drought with the size of its beak.
The beak required in order to feed on the hard seeds needed to be stronger and longer.
Due to this, the finch beak <em>evolved and developed into a stronger longer beak</em> adapted to feeding on large hard seeds.
Without this evolution, all the finches left on the Galapagos island could face <em>extinction out of starvation.</em>
Answer: Lek Polygyny
Explanation:
Polygyny is a mating system inwhich one male is associated with multiple females. This mating system is found in a few birds and insects, but is most common in mammals. Polygyny is a strategy used by males to increase their reproductive fitness.
Lek polygyny is a system where male aggregate at a location and try to attract females for mating and the females leave after mating. It is believed that males attract more mate in this way than in isolation.
Answer:
Saliva contains amylase, a starch digesting enzyme (chemical compound that catalyses the breakdown of starch); the starch gradually converts to sugar. Once the starch is broken down, the blue color disappears.
Hope that will help mwah!
Answer:
The DNA helicase comes and splits the hydrogen bonds that are holding them together which allows DNA primase and DNA Polymerase (3) to come and replicate the strands from 5' to 3'. Then both strands have half of the old and half of the new, and have a collected 2 double-helical structures, which means there is technically 1 copy.
Hope this helps!
Explanation:
Answer:
Because there is already presence of soil and nutrients in secondary succession
Explanation:
Ecological succession, which is the series of gradual change that occurs in a community over time, can be of two forms namely: primary succession and secondary succession.
- Primary succession is a kind of succession that occurs in a barren land where no form of life has existed before while secondary succession occurs on a land that has been previously colonized by certain organisms called PIONEER SPECIES, and hence, a substrate containing nutrients called SOIL for growth is available during secondary succession.
This accounts for the reason the secondary succession is faster than the primary succession because there is already presence of soil and nutrients in secondary succession.
