❖ The term that matches this statement is Metaphase. Metaphase occurs in Mitosis and Meiosis. The homologous chromosomes line up in single file.

Answer: B. It is associated with a negative change in free energy.
Explanation:
<u>A polymer is an organic compose made of many simple molecules </u>that are repeating structural units called monomers. Examples of polymers are DNA, lipids, carbohydrates and proteins.
Polymers are broken down into monomers in a process known as hydrolysis, which is a reaction that splits the bond between monomers. During these reactions, the polymer is broken into many components.
This process of breakdown is called catabolic reactions, which, as it was said, is the break down of larger molecules into smaller molecules through the hydrolysis of its bonds. <u>This reaction releases energy which was found in the bond between this monomers.</u> And, when energy is released, there is a negative change in free energy. This means there is more free energy available for the cell to be used.
Answer:
Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy
Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.
Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.
Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.
Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.
Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.
Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.
Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.
Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.
Answer:
by inhibiting the mitotic spindle plasticity
Explanation:
In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).
