Answer:

B. In horizontal rock layers, each layer is younger than the one below it

Explanation:

Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence. ... It is one of the great general principles of geology..

What is one way that early scientific practice differed from modern scientific practice?
Kobotan [32]
Well considering how far you want to go back, back in the witch trial days, science wasn't even practiced because it was believed to be tied into witchcraft. but in the medieval times, they believed that science should follow the teachings of the church, anything outside of the church's beliefs were labeled as "hypocrisy." hope this helped! feel free to ask me anything ^^<span />

Which of the following is TRUE? Conjugation is a type of reproduction During fission, a conjugation tube forms between the donor
emmasim [6.3K]

Answer:

THE FOLLOWING ARE TRUE;

1. CONJUGATION IS A TYPE OF REPRODUCTION

2. CONJUGATION INCREASES THE GENETIC DIVERSITY OF BACTERIA

3. FISSION CAN OCCUR AS OFTEN AS ONCE EVERY HOUR UNDER IDEAL CONDITIONS

Explanation:

Conjugation is a form of reproduction in bacterial cells in which cells transfer DNA by direct contact with the recipient cell. The process is mediated by plasmids which are non-chromosomal DNA molecules. Conjugation occurs in one direction because the donor cell is the only one with the conjugate plasmids. The donor cell sends out its sex pilus and attaches it to the recipient cell creating a conjugal bridge from which genetic materials can be transferred between the two cells. The bacterial chromosomes can also be transferred through conjugation. Conjugation allows for genetic diversity in bacterial cells because the transfer is unilateral and non-identical daughter cells are produced.

Fission of bacterial cells involves the splitting of the bacterial DNA that is replication, then the bacterial cell elongates and later split into two daughter cells with identical DNA. Fission in bacteria can take place every twenty minutes or often every hour under ideal and optimum conditions and a bacteria can produce a generation in just few hours.

During fission a conjugation tube is not formed, conjugation tube is formed during conjugation type of reproduction of bacterial cells and also conjugation does not produce genetically identical daughter cells because wide varieties of DNA or genes can be transferred resulting in bacteria with traits of several different species.
