You have found that there is an area around one of Nina’s brackets that has tenacious calc. In order to remove successfully you determine that you need more lateral pressure than you are able to generate with your dominant hand alone.  Which of the following advanced fulcrums best meets the demands of this situation?

Eukaryotic cells carry out multiple metabolic processes in order to harness energy from the environment. Cellular respiration refers to a series of metabolic pathways that convert glucose into usable energy. In [answer1], glucose is converted to pyruvate. Pyruvate then enters the [answer2], where it is converted to carbon dioxide during the [answer3] cycle. The electrons that are released during these earlier stages are input into the electron transport chain, where [answer4] phosphorylation occurs. The end goal of cellular respiration is to produce a chemical called ATP, which stands for [answer5]. When oxygen is low, some cells can carry out an alternative metabolic pathway called [answer6]. Plant cells have a special organelle called the [answer7], where they harness energy from sunlight in a process called [answer8].

All living things share certain characteristics. For example, all living things are composed of one or more [answer1]. They [answer2] autonomously using DNA. They also need to obtain [answer3] to support metabolism. All organisms can sense and respond to the [answer4]. Organisms are also capable of maintaining constant internal conditions, a process called [answer5]. Finally, all organisms [answer6] as groups.

In eukaryotes, cells divide by a process called [answer1] division. This process includes multiple distinct phases. In [answer2], the chromosomes condense, and the [answer3] envelope fragments into small pieces. Next, the chromosomes align at the center of the cell, at the [answer4] plate. The mitotic spindle attaches to the chromosomes, at a special chromosomal structure called the [answer5]. The [answer6] chromatids separate during [answer7]. Finally, the chromosomes decondense during [answer8]. The cell itself physically divides during a process called [answer9]. During sexual reproduction, cells undergo a specialized type of cell division called [answer10].

Our understanding of genetics began with Gregor Mendel. Mendel established two laws of heredity. The law of [answer1] states that each individual contains two versions of each gene (alleles). These alleles separate during gamete formation, so that offspring receive one copy of each gene from one parent. Mendel’s law of [answer2] states that each gene separates independently of other genes. For a given gene, and individual can have two copies of the same allele – these individuals are [answer3]. Alternatively, they could have two different alleles, making them [answer4]. The phenotype that is observed in an individual with two different alleles is called the [answer5] phenotype, while the phenotype for the allele that is NOT observed is called the [answer6] phenotype.
