Because the gram stain differentiates two types of bacteria based on the composition of their cell walls.
Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the
phase,</em> - <em>the
phase,</em> - <em>the S phase; and</em>
- <em>the
phase</em>.
The phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of phase.
The correct option is b.
The parachute needs time to open up out of the compressed backpack.
Answer:
DNA, genes and chromosomes are inside every cell in your body. ... Bill defines a gene as a piece of a DNA molecule.
Explanation:
Answer:
fibrous, cartilaginous
Explanation:
There are two types of joint on the basis of composition of material such as fibrous and cartilaginous joints. Fibrous joints are those joints which are connected with dense connective tissue composed of collagen. These joints are immovable joints while cartilaginous joints are those joints which is connected to cartilage. It is movable joint which allows some movement to the joint.
