Answer:39 chromosomes
Explanation; meiosis is a form of nuclear division that produces gametes with half the number of chromosomes in the parent cell.it involves two successive divisions to produce four daughter cells.meiosis occurs only in reproductive cells.
In this case,the dog has 39 pairs of chromosomes,which is 78 chromosomes.it would undergo meiotic division to produce the half number of chromosomes,which is 39 chromosomes.this 39 haploid chromosomes are contained in the sperm cells or in the egg cells.
When the egg and sperm fuses,the diploid number of chromosomes is restored.

Answer:
The correct answer is 7.5 ml
Explanation:
The medicine contains 100 mg in 5 ml, that means that the concentration of the active ingredient is 100 mg/5 ml= 20 mg/ml
If we divide a concentration (in mg/ml) into a mass (in mg) we obtaine a volume (in mL). Thus, in order to calculate the mililiters of medicine which contain 150 mg of the active, we have to only divide mass (150 mg) into the concentration of active ingredient as follows:
mL =
= 7.5 mL
Answer: Composition maybe?
Explanation:
Evidence supporting the Big Bang theory includes the presence of cosmic microwave background radiation, visual observation of redshifted objects and the abundance of primordial elements found throughout the universe.
