Answer:
The embryo passes through multiple rounds of the cell cycle, but cytokinesis does not occur during M phases.
Explanation:
The cell cycle includes a series of events that make new cells from the existing cells. During the process, nuclear division during the M phase produces daughter nuclei. Nuclear division is followed by cytokinesis. Cytokinesis is the division of cytoplasm and results in the formation of daughter cells.
If a cell undergoing cell cycle forms daughter nuclei by mitosis, all the daughter nuclei are genetically identical. In the absence of cytokinesis, cytoplasm would not divide and the daughter nuclei will remain in the parent cell only. Repeated nuclear division without cytokinesis would produce multiple nuclei present in the parent cell.
The answer is C. I hope this helps
The scientist is examining a disaccharide molecule.
Disaccharide is a form of sugar or carbohydrates or is an organic molecule that contains two simple sugars linked together. Like monosaccharides, disaccharides are the sugars soluble in water. Maltose, lactose, and sucrose are some examples.
Monosaccharides are joined to form disaccharide sugars through a condensation reaction, which requires the removal of a water molecule from the functional groups. A type of enzyme called a disaccharidase is used in the process of hydrolysis to separate a double sugar into its two monosaccharides.

This process is active transport.
Unlike other methods such as diffusion or osmosis, active transport requires extra energy provided by the organism from such as cellular respiration. In addition, they also require a carrier protein, which can change its shape to bring the substance through the cell membrane.
Some examples requiring active transport may include root hair cells absorbing mineral ions, or our small intestine absorbing digested nutrients into our body.
