Plant cell walls are rigid membranes on the outermost part of the cell. The cell wall provides a structured shape for the cell, helping the cell retain its form and shape. The cell wall also controls the rate of replication, allowing plant cells to replicate at a much slower rate than animal cells.
Answer:
The correct answer would be - mycobacterium, and streptomyces.
Explanation:
Actinobacteria is a phylum that consists of a group of gram-positive bacteria with cytosine and guanine content in their DNA. These bacteria can be aquatic or land bacteria. Actinobacteria do not have cell wall however they make a non-sptate and mycelium.
Mycobacterium is one of the genera of the actinobacterium phylum. This genus includes pathogenic species in it that cause deadly diseases in humans and other mammals such as leprosy and tuberculosis Whereas streptomyces is another genus of the actinobacteria that is yielded the very first drug to fight with the ancient scourge.
Thus, the correct answer is - mycobacterium and streptomyces.
Answer:
As a result of the Hershey and Chase experiments, scientists believe
that the “transforming principle” is DNA.
Explanation:
Hershey and Chase determined that DNA, not protein, was the inherent material. They resolute that a defensive protein coat was molded everywhere the bacteriophage, but that the interior DNA is what discussed its capability to produce offspring inside a bacterium. Transformation occurs when one bacterium picks up free-floating DNA and incorporates it into its own genome. When scientists first observed this behavior, it seemed that genes were transforming one type of bacteria into another, so they concluded there must be a 'transforming principle' at work.
Answer:I don’t know this one.
