Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
Answer;
Population; physiological modifications at the individual level.
The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Explanation;
-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.
-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
The answer would be C. A haploid cell.
Gametes are haploid cells made by meiosis. Male and female gametes fuse together during fertilization and form the diploid zygote.
