Answer:
Polyphenol oxidase (PPO) activity was determined by measuring the initial rate of quinone formation,
as indicated by an increase in the absorbance units (AUs) at 420 nm. An increase in absorbance of 0.001 min−1 was taken as one unit of enzyme activity
<h2>Active & Passive transport</h2>
Explanation:
- Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
- Molecules move against a concentration gradient ( low concentration ―→ high concentration)
- Cellular energy (ATP) is required
- Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
- Molecules move along the concentration gradient (high concentration ―→ low concentration)
- No cellular energy is required
Answer:
In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.
Explanation:
In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).
