Answer:
The fluid constituent of the cytoplasm is known as the cytosol, and within the cytosol various organelles are present. The first or the initial stage of cellular respiration, that is, glycolysis takes place within the cytosol of the eukaryotic cell. Glycolysis in simple terms is also known as the dissociation of sugar molecule. In the process of glycolysis, glucose gets transformed into the molecule of pyruvate.
The pyruvate, that is, the end product of glycolysis is further used in other steps of cellular respiration. The other steps of cellular respiration take place within the mitochondria.
A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
