in bacteria binary fission can be modeled in

Question

A. Two stages
B. One stages
C. Four stages
D. Three stages

Answer 1

Binary fission in bacteria is typically modeled in A. Two stages.

This process involves:

1. DNA replication – where the bacterial DNA is copied.
2. Cytoplasmic division – where the cell divides into two daughter cells, each containing a copy of the DNA.

Thus, the process is simplified to these two primary stages.

Answer 2

the process by which a modified stem or root of a parent plant grows offspring that remains attached is called
A. Tuber reproduction
B. Fragmentation
C. Vegetative reproduction
D. Binary fission

Answer 3

The process by which a modified stem or root of a parent plant grows offspring that remains attached is called C. Vegetative reproduction.

This type of reproduction involves structures like runners, tubers, and bulbs, where new plants grow from parts of the parent plant. In this context, the offspring are often still connected to the parent plant until they are ready to establish themselves independently.

Answer 4

Without external forces, the third generation of a bacterium and the original parent cell will have approximately _matching DNA sequences. (1 point)
A. 33%
B. 100%
C. 25%
D. 12.5%

Answer 5

Without external forces, the third generation of a bacterium and the original parent cell will have approximately B. 100% matching DNA sequences.

Bacteria reproduce through binary fission, which means that the daughter cells are genetically identical to the parent cell, barring mutations or external genetic influences. This results in the original cell and its descendants having nearly identical DNA sequences.
