Human sperm and eggs contain 23 chromosomes. Human zygotes contain 46<span> chromosomes. The type of cell division that produces gametes with half the normal chromosome number is called meiosis. It is used to produce cells for repair and asexual reproduction.</span>
Answer:
Profase - Metafase - Anafase - Telofase - Citocinesis
Explanation:
Estas fases ocurren en orden estrictamente secuencial y la citocinesis —el proceso de dividir el contenido de la célula para hacer dos nuevas células— comienza en la anafase o telofase. Etapas de la mitosis: profase, metafase, anafase y telofase. La citocinesis típicamente se superpone con la anafase o telofase.
Explanation:
The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.
Answer: Photosynthesis: The process of synthesis of food form inorganic raw materials in chlorophyll
The reactants are water and carbon dioxide while glucose, water, and oxygen are products
Dark reactions occur in the grana of chlorophyll, and get energy from ATP and NADPH.
The reactants are water and carbon dioxide.
The products are organic sugar molecules
