Answer:
We can change the physical state of a substance by heating or cooling it. For example, liquid water can be heated to convert it into the gaseous form i.e steam. Steam can be cooled or condensed to convert it into liquid water.
Liquid water can be cooled to convert it into the solid physical state which will be ice. Ice can be heated to convert it into liquid again. Hence, we can change the physical states by heating or cooling a substance.
Answer:
Chemical bonds of ATP
Explanation:
Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups
Answer:
Basic Research
Explanation:
The initial discovery and analysis of the Lake Vida bacteria allowed them to be classified thereby leading to an understanding of their basic metabolic processes.
Although ,the introductory passage suggested several ways that this could lead to applied research by allowing the development of new products.
Conclusively, the research is a basic in nature because it gave a better understanding of the natural world.
<u>Answer</u>:
It is important for the chromosomes to condense during mitosis to facilitate chromosome movement.
<u>Explanation</u>:
The chemical called colchicine is found to be used during the process of mitosis, so as to freeze the cells, which can stop or prevent the movement of the chromosomes. This process is also essential for the faithful genome replication or transmission to those daughter cells. During the interphase cell division occurs but during the prophase the cell condensation is found to be happening. Before the process of the mitosis chromosomes are allowed to move and during this entangled and breaking were also noticed.
