Natural disaster e.g. Global warming
This photo shows the differences between phloem and xylem/functions of stems
description of root: is the organ of a plant that typically lies below the surface of the soil.
function of roots: absorption of water
storage of food and nutrients
description of leaves: organ of a vascular plant
function of leaves: gas exchange occurs here!!!
1) leaves have large SA for fast diffusion
2) contain many stomata to allow movement of gases into and out of the leaf.
Answer:
The correct answer is c. Specific beak sizes are adaptations to the seeds of different species.
Explanation:
Allopatric speciation occurs when a population of a species is isolated geographically from their group. Then these isolated populations evolve in different species due to the selective pressure of natural selection.
The best example of allopatric speciation is seen in finches that live in the Galapagos Islands. These finches are isolated due to oceans on different islands of Galapagos and they developed different types of beaks according to the food they get on their island.
Some developed large blunt beaks to crack nuts, some developed long beaks to eat flowers and due to geographical isolation they did not interbreed and developed into a new species of finch. Therefore the correct answer is c.
The maximum rate of DNA replication in E coli is 1000 NUCLEOTIDE PER SECOND.
DNA replication is the process by which living cells produce two identical DNA from one original DNA molecule. The process occur in all living cells and its the basis of inheritance. In E coli, DNA replication starts from a single point of origin and proceeds in two different directions and new nucleotides are added to the replicating fork at the rate of 1000 nucleotides per second.<span />
