Frogs are amphibians, which means they need to live in both water and land.
They are adapted to hop on land with their feet, and their tongue to eat.
The reason frogs have lungs and also breathe through skin is so they can breathe in both of their habitats
Hag Fish and Lamprey
Vertebrates are the organism which posses a vertibral column(aka the spine or back bone structure), while the earliest had a head they lacked a spine and jaw, these jawless vertebrae lived 500-600 million years ago. they are the ancestors of bony fish which in time became amphibians and other groups of animals
Answer:
5556
Explanation:
If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.
However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.
5556 molecules of DNA polymerases acting on 5556 origins of replication are needed.
Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
