Yuki888 [10]

Answer:

Simple cell

Explanation:

Simple cells are found in primary visual cortex and are made up of large number of receptive fields from neurons and the respond to light at specific Orientation and oriented edges. The cells were discovered by Torsten Wiesel and David Hubel in the late 1950s. The simple cells respond to stimuli with some particular orientations to objects within their receptive fields. Receptive fields comprises of sensory receptors in the sensory neurons that draw out neurosonal responses when there are stimulated

Gala2k [10]

Answer:

The reason why there is so much diversity of life, despite the fact that DNA is the same for all living things, the pairings are always the same and there are only six components that make up the DNA, is that sequences of base pairs are different.

Explanation:

DNA is the molecule that contains all the genetic information, whose structure consists of four nitrogenous bases, adenine, guanine, thymine and cytosine, plus deoxyribose and a phosphate group. This DNA molecule constitutes the basis of life and inheritance of all living beings.

The nitrogenous bases of DNA are found in a number and specific sequences, which determine the proteins and biomolecules that must be synthesized in the cells.

What makes different types of living beings and diversity of life is the length of the DNA and the sequence of bases that form part of each molecule.

The other options are not correct because:

  • <em>The sugar component of DNA is always the same, not different. </em>
  • <em>Organisms always use DNA in the same way. </em>
  • <em>The DNA molecule is always the same.</em>
