Answer:
The experiment conducted in 1952 by hershey and chase consisted in the use of sulfur to track proteins and radioactive phosphorus to track DNA from T2 phages that infect bacterial cells, the key result was that phage proteins were outside the cell during the infection but the DNA was inside the cells because new phages were obtained with radioactive phosphorus. This allows us to conclude that DNA acts as a genetic material of phage T2
Answer:
c. imprinting
Explanation:
Imprinting is the object of study of ethology, which is related to animal behavior. In the early stage of an animal's life, imprinting is an essential and most conducive phase for learning and subsequent development. The two main types of imprinting are sexual and filial. In sexual imprinting, a young animal learns the traits it seeks in a mate. Affiliate imprinting is the learning of a offspring from his / her parent.
In the case of the salmon fish situation, the need for workers to raise fingerlings (salmon) in stream water during a certain critical period in their early development is an example of imprinting. In this case, imprinting is necessary for the development of this animal in a different environment from the one it was raised.
The movement of particles in diffusion are determined when particles from one area go to another with little or no particles.
Answer:
mitochondria
Explanation:
In aerobic glycolysis: NADH is transferred into mitochondria via the mitochondrial shuttle, where it is oxidized to NAD in the respiratory chain, ultimately producing ATP.
They are all freshwater. So the closest would be c. an estuary since it has a free connection with the sea since the sea is not freshwater.
So C.
hope this helps!
