<span>Biotic factors are the living components of an
ecosystem. They are sorted into three groups: producers or autotrophs,
consumers or heterotrophs, and decomposers or detritivores.</span>
<span>The
answer is facilitated diffusion. It requires no energy because the ions are
traveling down the concentration
gradient. Facilitated diffusion is important
for the regulation of ions in a cell. It also enables
ions to pass across the hydrophobic layer of the cell membrane composed
of phospholipids.</span>
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).
