First-division nondisjunction will only yield gametes with an extra chromosome. True or False

Biology
1 answer:
frosja888 [35]3 years ago
5 0

Answer: False  

Explanation:

Non disjunction of the chromosomes can be defined as the condition in which homologous chromosome fails or the sister chromatids fails to separate properly during the time of cell division.

In case of the first division non disjunction will yield a cell with an extra chromosome besides normal and another cell with no chromosomes in it. Incase of the normal condition a parent cell divides into two daughter cells with one chromosome each.

This can be caused due to the failure of the homologous chromosomes to get separated during meiosis I. It results in the aneuploidy.

Why is mechanical digestion and important to chemical digestion
dangina [55]
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.

The taiga biome is sometimes called a coniferous forest. This is because it is home to many coniferous trees such as pine, spruce, fir, and hemlock.

Taiga biomes are found between 50 and 60 degrees north latitudes. The taiga is the largest land biome on Earth, covering over 15 percent of the Earth's land. A large area of taiga is located in the northernmost forests across Europe, Asia, and North America. The taiga generally has two seasons. The summers are short, moist, and warm. The winters are long, cold, and dry. Most precipitation is in the form of snow, though rain does occur during the summer. Most animals in the tundra hibernate or migrate during the winter. Hawks, bears, foxes, wolves, deer, bats, and chipmunks can be found in the taiga.

Pollen tube used to transport pollen from the stigma of a flower to the ovary. Actually, it begins to grow when lands on the stigma. It grows until it reaches an ovule which is inside the ovary. This way it is secured that a nucleus of pollen will fuse with a nucleus of the ovule and that fertilization will occur.
