Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
UV light caused cancer because it damages the DNA in our cells. Changing the characteristic of a cell can cause cancer
When this occurs the neutrons released by a fission reaction continue striking more nuclei. If the fuel rods in a reactor vessel produce too much heat, this condition may occur.
Answer:
The question lacks options, the options are:
A. moisture content of seed must be at least 9%
B. Moisture content of the seed must be less than 9%
C. certain enzymes in the seed are activated
D. temperature must be above 80 degrees
E. temperature must be below 80 degrees
The answer is A
Explanation:
Germination is practically the very first step of every seed-producing plant. It is the process whereby seeds sprout or begin to grow. Germination requires certain conditions to be met in order to occur. This conditions include presence of moisture in the soil etc.
The water is absorbed by the seed helps to soften the seed coat, which protects the seed from damage. The seed coat ruptures, causing the emergence of growth structures from the seed. In general, seeds need water to activate their dormant physiology. Hence, the moisture content of the seed must not be lower than 9%.
