Answer:
CENTROMERE
Explanation:
The CENTROMERE is the primary constriction region where the identical DNA molecules are most tightly bonded to each other during mitosis and meiosis.
The typical chromosome in metaphase is composed of two sister chromatids joined by the centromere.
Surrounding the centromere, we can find the kinetochores. These are laminar proteinic structures forming a plate where the spindle and kinetochore fibers will join during chromatids separation.
The position of the centromere defines the chromosomes as acrocentric, metacentric, or submetacentric.
Answer:
Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Answer:
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
Explanation:
Let the allele for dark brown pigment be represented by "B"
And the let allele for white (no pigment) be represented by "b"
Due to incomplete dominance, the phenotype of heterozygous species would be "light tan"
Genotype of heterozygous female - Bb
Genotype of heterozygous male - Bb
Bb * Bb
BB, Bb, Bb, bb
BB - Dark brown color - (1/4)
Bb - light tan (due to incomplete dominance) - (2/4 or 1/2)
bb - white color - (1/4)
