Answer:
Cells are the smallest unit of life. All living things are made of cells. Your whole body is made up of different kinds of cells, each with a different job to do.
Giemsa stain shows the staining of centromeres.
- C-banding, which involves denaturing the chromosomes in a saturated alkaline solution followed by Giemsa staining, is a technique specifically used to identify heterochromatin.
- Different banding methods can be selected when identifying chromosomes. Chromosome banding is an important technique used in chromosome karyotyping to distinguish between normal and defective chromosomes for clinical and scientific purposes.
- The most common dye-based chromosome banding methods are Giemsa (G), reverse (R), and centromere (C). G-banding stains trypsinized chromosomes, whereas R-banding uses hot acidic saline to denature the chromosomes prior to Giemsa staining.
- It contains a significant amount of AT-rich satellite DNA. Just as G-banding represents AT-rich sections of chromosomes, so does Q-banding.
Therefore, centromeres is the correct answer.

Both the Artic (North Pole) and the Antarctic (South Pole) do not receive direct sunlight, which leads to extremely cold temperatures.
In the Summer, the average temperature in the North Pole is around 32F (0C) and in the South Pole, the average in the summer is -18F (-28.2C).
In the winter, the average for the North Pole is -40F (-40C) and in the South Pole its -76F (-60C)
Answer:
1How does testosterone enhance performance? Testosterone acts on muscle cells by binding to a specific receptor protein, the androgen receptor. Upon testosterone binding, the androgen receptor signals to the muscle cell to activate the pathways that trigger an increase in muscle mass, called muscle hypertrophy.
2The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH. When oestrogen rises to a high enough level it causes a surge in LH from the pituitary which causes ovulation where an egg is released from the follicle (Day 14 of the cycle).
