Yes this is true. scientists discover different fossils at different times, usually discovering the oldest ones first. they find more information about life that existed. in conclusion, this statement is true
The substances that are being used up in cellular respiration are oxygen (O2) and glucose (C6H12O6). They are the main reactants. Cellular respiration happens in the mitochondria, the power house of the cell. Hope this answers the question.
Answer:
D
Explanation:
Conjugation is one of the processes employed by bacteria cells for genetic exchange. It involves the transfer of genetic material from one bacterium (donor) to another bacterium (recepient) via direct contact.
The donor bacterium carries a DNA sequence called Fertility factor or F-factor, which allows it to synthesize a tube-like stucture known as pilus (plural - pili). The pili that performs this function in bacteria is called CONJUGATE PILI. The pilus draws the mating pair (donor& recepient cell) close to each other to form a wall-wall contact triggering the formation of a mating bridge. This bridge enables the transfer of genetic material, usually in form of a plasmid (a small circular piece of DNA capable of replication independently of the bacterial chromosome).
In bacterial conjugation, the process involves a small portion of the genome of the donor cell getting inculcated into the complete genome of the recepient cell. Hence, conjugation is of immense importance to bacteria, as it is an avenue to confer certain genes e.g. antibiotic-resistant genes.
If you are saying they get a bad reputation for being dangerous, most likely because sharks in general a stereotyped and I am not sure ehh they evolved like that
A becuz that is the only answer where it is solid
