SVETLANKA909090 [29]

Answer:

The correct option is A. they evolved from land mammals.

Explanation:

Evolution can be described as a process through which organisms in a species change over a period of time due to the natural selection of the environment. Those organisms that have many similarities in their functions or structures are considered closer to one another and have the same common ancestors.

The properties mentioned in the question about cetaceans resembles the properties of land mammals. For example, cetaceans lack gills and breathe air. Land mammals also do not have gills and need to respire for living. The cetaceans have fin bones which are similar to the limb bones in the land mammals. Hence, these observations show that cetaceas have evolved from land mammals.

Elena L [17]

There are two types of bipolar cells present in the retina which are differentiated on the way the centres of their receptive fields respond to light. The names of bipolar cells are ON-centre and OFF-centre.

If a light fall at the centre of the receptive field of a bipolar cell, it will experience an exciting effect on that cell, resulting in it being depolarized, it is an ON-center cell.

Hence, the correct option is B.

150 - 300 bp

Explanation:

Micrococcal nuclease, indistinctly from the time of treatment and in average organisms, will realize the cuts on DNA o RNA zones rich in AT or AU. It is not a specific endonuclease.

Even so, the mean size of the expected fragments will have between 150 bp and 300 bp.

It is very important to run your digestion along with a proper label.
