Mitosis - 48 chromosomes (diploid cells)
Meiosis - 24 chromosomes (haploid cells)
Diploid cells. Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.</span>
Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
Explanation:
algea bottom of foodchain with water worms and mice?
Answer:La transición de formas de vida unicelulares a multicelulares ha ocurrido en más de una ocasión a lo largo de la evolución. Las plantas, las algas marrones, los hongos y los animales han adquirido estilos de vida multicelulares de forma independiente y convergente.
La aparición de los animales representó un paso evolutivo clave en la historia de la vida. El desarrollo embrionario y todas las funciones que requiere la vida multicelular se hallan conservados en todos los animales, desde las esponjas a los humanos.
La secuenciación de los genomas de las especies unicelulares más cercanas a los animales ha revelado que estas ya contenían muchos de los genes necesarios para la multicelularidad. Estos habrían sido reutilizados para nuevas funciones multicelulares en el ancestro común de todos los animales.
