igor_vitrenko [27]

Answer: Divergence

Explanation:

One postsynaptic cell has the ability to receive the input from large number of different presynpatic cells and the divergent neurons can have connections with different postsynaptic cells.

The divergence in the neurons allows one neurons to have communication with the other neurons within a network.

The divergence neurons can communicate with any of the neurons (output) in the network.

Mutation is a random and non-adaptive process. This was first proven by:
s2008m [1.1K]

Answer:

Option (d).

Explanation:

Mutation may be defined as the sudden, heritable change in the nucleotide sequence of the organism. Mutation may occur due to the errors in DNA replication or may occurs due to the mutagens.

Joshua and Lederberg experiment explains that mutation is the non adaptive and random process that occur in the organism. He used the replica plating of E.coli and grows them on streptomycin drug. The bacteria was grown on the the primary plate and they are transferred to the secondary plate with streptomycin drug in the growth environment. The resistant strain of bacteria grows in the streptomycin environment.The pattern of bacteria growth on the plate explained that mutation occurs randomly and it is a non adaptive process.

Thus, the correct answer is option (d).

VLD [36.1K]

Answer:

are influenced by many different genes

Explanation:

A quantitative trait is a given phenotypic trait influenced by the combined effects of many genes and its environment. A quantitative trait locus (QTL) is a region of DNA (i.e., a <em>locus</em>) associated with the variation of a quantitative trait. In the last years, some QTLs correlated to the variation of HDL, LDL, and triglycerides levels were mapped in different genomic regions, thereby showing that these complex traits are regulated by the interaction of multiple genetic <em>loci</em>.
