Answer:
If the paired chromosomes fail to separate during meiosis in the female, then the resulting daughter cells will receive either 2 or no copies of chromosome 21. If the resulting egg with 2 copies of chromosome 21 is fertilized with a normal sperm, the resulting zygote with be trisomy 21
Explanation:
Answer:
hey!!
Explanation:
The answer is 36
Mitosis is a cell division that produces 2 cells daughter that are genetically identical to both the other daughter cell and the parent cell. The process where the parent cell first duplicates its genetic material, then it divide so that both daughter cell receive the exact number and same DNA.
Therefore, the answer is 36, only 36 matches the description of genetically identical cells.
Answer:
light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.
Explanation:
lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.
