Hi , cytoplasmic streaming is actually circulating around in the cell . It moves and by doing do it can help move organelles and harmful/helpful chemicals to where they need to be in the cell , so that's why cytoplasmic streaming is also called active mass movement of cytoplasm.

Answer:
The correct answer would be C, burning of wood and coal
Explanation:
The burning of fossil fuels (coal, oil, natural gases) increases the greenhouse gases in the atmosphere.
Cancer cells affect the cell cycle by not following the checkpoints and dividing abnormally and not getting destroyed by the process of apoptosis leading to the formation of tumours.
In the cell cycle during the mitotic phase the cell divides resulting in two daughter cells and segregation of DNA occurs in this. In cell cycle, there are checkpoints of signalling pathways which determine when the cell has to grow and divide. The healthy cells follow the cell cycle.
Explanation:
Cancer cells become immortal and result in faulty proteins which are not required by the system. The cancer cells grow uncontrollably and are abnormally shaped.
The cell cycle has check points at S phase and G2 phase before it enters the Mitotic phase of division. Normal cells follow the checkpoints.
In DNA there are two types of strands, 5'/5 prime, which is the strand, aka the leading strand.
There is also the 3' strand which is the lagging strand.
The difference between these two is the the leading strand is discontinous during replication, they must create ozaki fragments.
The other lagging strand can just have the whole strand replicated at the same time
Answer:
DNA
proteins
genes
chromatin
chromosomes
chromosome
Explanation:
The “code” for physical traits is found in a molecule called DNA. Segments of this molecule that code for specific proteins are called genes. In order to conserve space and protect the molecule, DNA wraps around proteins to form chromatin. When a cell is about to divide, DNA wraps up even tighter into chromosomes. Complex organisms have many molecules of DNA in every cell, and each molecule is commonly referred to as a chromosome, even if it is not wrapped up as one.
