Eukaryotes include options (A) and (D), while bacteria only pertains to (E), and both (B) and (C). (A) Eukaryotes are the only ones that possess a nucleus. (B) Both types duplicate their DNA prior to cell division, ensuring each cell retains a copy. (C) The structural element is known as a centromere in eukaryotes, whereas bacteria use the origin of replication for this function. (D) Centromeres are unique to eukaryotes. (E) Bacteria exclusively contain a replication origin.
C. Era del Precámbrico Tardío. El término eón se refiere a dos o más eras geológicas que componen un eón. Se divide principalmente en cuatro eones: Hadeano, Arcaico, Proterozoico y Fanerozoico. Este último incluye las eras Paleozoica, Mesozoica y Cenozoica. El Cámbrico forma parte de la era Paleozoica, la cual fue un período crucial en la escala de tiempo geológico por el repentino desarrollo de una gran diversidad de filos animales. Durante este tiempo, también apareció la primera planta terrestre, lo que fue un avance prometedor para el crecimiento de vegetación en condiciones estacionales adecuadas.
Answer:
1128.
Explanation:
The phenotype for dominant tasters is 1482.
The phenotype for recessive tasters = 2400 – 1482 = 918.
Recessive phenotypes = 2400 – 1482 = 918.
The frequency of the recessive phenotype = q² = 918 / 2400 = 0.38.
The frequency of the recessive allele q = √0.38 = 0.62.
For the dominant allele frequency, p = 1-q = 1- 0.62 = 0.38.
The heterozygous frequency = 2pq = 2 × 0.38 × 0.62 = 0.47.
The number of heterozygous individuals within the population = 0.47 × 2400 = 1128.
Thus, the result is 1128.
Answer:
The answers are - a, and b.
Explanation:
Plasticity refers to the brain's capacity to adapt and undergo changes throughout an individual's life. It showcases an impressive capability for recovery following surgical intervention or damage to the brain.
Neurogenesis signifies the ability to regenerate nerve cells, which can occur in adults but typically requires around six weeks to take place.
Consequently, the answers are - a, and b.
