Answer:
1. The 2 bases forming each rung of the 'ladder' snap apart. This is caused by an enzyme that passes along the strands, 'unzipping' it
2. Spare nucleotides (in the nucleus of the cell) attach themselves to the 'broken rungs' to repair the break. Each repairing nucleotide is identical to the broken one
3. As each 'broken rung' is repaired, two 'ladders' form, that is 2 identical strands of DNA. The 'repairing' is really the process of replica

Answer: a
Explanation:
Because the top predictors only eat meat, and not the plants, so if you take out the primary consumers, then the top predictors will begin to die out.
The correct order of sequence is B-A-C.
Anaphase begins with separation of the duplicated centromeres of each pair of sister chromatids. The daughter chromosomes starts moving toward opposite poles due to the action of the spindle fibres. As this stage chromosomes appear like V or J shape. At the end of anaphase, a complete set of chromosomes has gathered at each pole of the cell.
The answer is C. exocytosis.
Exocytosis is a process in which vesicles in the cell moves to the cell membrane to fuse with it. This way, the vesicles release their contents to the extracellular matrix. The purpose of exocytosis is to transport large molecules out of the cell because they are too large to pass passively through the cell membrane.
Exocytosis is the opposite process of<span> endocytosis,</span><span> in which cell engulfs molecules, such as proteins. Pinocytosis is fluid endocytosis. In exocytosis, cell transports molecules, such as proteins, out of the cell.</span>
