Which is occurring during conjugation? A. There is a change in the nucleotide sequence of a DNA molecule.

B. A bridge-like connection is created between bacterial cells for genetic material to
be transferred.

C. A bacterial cell takes DNA fragments from a dead cell and incorporates them into
their DNA molecule.

D. There is a transfer of DNA from bacterium to another by a virus.

B. A bridge-like connection is created between bacterial cells for genetic material to  be transferred.

Explanation:

A. There is a change in the nucleotide sequence of a DNA molecule.  - this is describing a genetic mutation

B. A bridge-like connection is created between bacterial cells for genetic material to  be transferred.  - this is conjugation, a type of genetic transfer between donor and recipient bacterial cells. It is a way that bacterial cells achieve genetic variation. For example, bacteria can share antibiotic resistance genes between one another. They do not directly contact one another, instead, they use a structure called a pilus to exchange material

C. A bacterial cell takes DNA fragments from a dead cell and incorporates them into  their DNA molecule.  - this is transformation, another type of genetic transfer where bacterial cells take up bacterial DNA from the environment. These molecules of DNA are usually from dead bacteria

D. There is a transfer of DNA from bacterium to another by a virus. - this is another type of gene transfer called transduction, where a virus takes genetic material from one bacteria to another.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
