Around the year 1800, it was discovered that fossils are arranged in comparable patterns within the layers of the Earth. Name 3
frez [133]

Answer:

Study of comparative anatomy emerged in the 18th century and led to establishment of relationship between species based on the common traits

Explanation:

The three major events that occurred after this discovery are –  

a) Discovery of the fact that the age of earth is much higher than the age of earth as found in previous theories of continental drift theory

b) The age of the oldest fossils was determined and based on that relative age of all species (as found in fossils) was determined.  

c) The determination of age of fossil helped to find the gaps in the evolutionary tree and hence provoked search of these missing species.

The study of comparative anatomy started somewhere around 1800 when George Cuvier emerged as father of comparative anatomy

Based on comparative anatomy study, scientists such as Buffon and Lamarck worked on establishing relationship between species based on the common traits shared between them

The enzyme that makes new strands of DNA only in one direction is:_______ primase
Wittaler [7]

Answer:

Option C

Explanation:

Primase synthesizes DNA polymerase through the initiation of synthesis of RNA primer. DNA polymerase is able to add nucleotides in only one direction towards the direction of replication fork Hence, it add to the chain only at 3’ end  and build new strand from 5’ to 3’ end.  

The 5’ to 3’ strand is the leading strand and is easy to build as 5’ to 3’ progresses towards the replication fork and DNA polymerase also move in the same direction

Hence, option C is correct

ur data for diffusion of water across a differentially permeable membrane in response to a sucrose gradient could be graphed wit
musickatia [10]
The slopes show that sucrose gradient affects change in weight.

The slopes will be different because higher gradient concentration of sucrose will result in the higher amount of water moved. This means the higher sucrose gradient concentration, the more change in weight of the water.
