This is true because certain manufacturing companies and other industries still donot comply with the governmental regulations and release the toxic wastes containing sulfates, into the water bodies. This contaminates them and the maximum allowed sulfate level of the water body exceeds its limit.
SPINDLE FIBERS
In Mitosis, Spindle Fibres form at opposite poles of the cell and meet at the equator. Collectively, they form a spindle-shaped structure which attach to Centromeres.
CENTROSOMES
The organelle located near the nucleus in the cytoplasm,
composed of 2 centrioles that divides during S Phase
Centrioles are surrounded by a mass of proteins (Pericentriolar Material (PCM))
Migrates to opposite poles of the cell during mitosis
Involved in the creation of spindle fibres
CHROMOSOMES
A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Centromeres
The constricted region joining the two sister chromatids that make up an X-shaped chromosome. It also serves as the point of attachment for spindle fibers when the spindle fibers are pulling the chromosomes toward the centrioles (situated on opposite poles in a cell) prior to cytokinesis.
Answer:
B. The ddNTPs lack a 3′ hydroxyl group.
Explanation:
Dideoxynucleotides is a family of inhibitors of the DNA polymerase, its official name is 2',3' dideoxynucleotides but they are commonly called ddNTPs. One of the main characteristics of this compound is the absence of the 3'-hydroxyl group in the deoxyribose, due to the absence of this group, it is impossible to form a phosphodiester bond between nucleotides and the DNA synthesis is stopped.
Answer:
every cell in you body needs oxygen to help it metabolize it release from food for energy.cells that do the same job combines together to form body tissue such as muscles,skin bone tissue.cells can take in fuel.cells not only make up living things,they are living g things.
Answer:
zero
Explanation:
Displacement is a vector, meaning that the direction is very important. Displacement is the distance from the starting point to wherever the object is. So a car that does a 500 m lap will have covered 500 m in distance but displacement is zero because, having come back to the starting point, the distance between the starting point and where the object is, is zero.
