2- Explain how land that gets broken up can<br> contribute to loss of species diversity
Minchanka [31]

Explanation:

Broken up land land contributes to a loss of species diversity through geographoc isolation. Geographic isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.

Further Explanation:

Spontaneous modifications in the genome can occur during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications called single nucleotide polymorphisms to large-scale deletions and multi-gene additions.

Such mutations create variations that within a group become dominant, resulting in the creation of different, genetically distinct organisms called species.

Regulatory proteins typically contain sites that can bind to other proteins or small molecules. Through such binding interaction
nasty-shy [4]

Answer:

Regulatory sites e.g enhancers and silencers

Explanation:

Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.

Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.

Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.

Why would it be pointless for reptiles to sit on their eggs to incubate them as birds do?
agasfer [191]
The best and most correct answer among the choices provided by your question is the second choice or letter B.

Reptiles don't sit on their eggs like birds do because r<span>eptile eggs are not amniotic and have no shell, so sitting on them would crush them.</span>
