The answer is <span>bird droppings that contain seeds from a different location.
</span><span>Gene flow includes a transfer of alleles from one population to another. So imagine a population of plant A on location 1 and another population of plant A on location 2. They cannot interchange their genes. But if birds drop seeds from location 1 and those seeds get to location 2, gene flow may occur.</span>

Explanation:
<em><u>Musca</u></em> <u><em>domestica</em></u> is the scientific name of an animal popularly known as Housefly. From the question, it is known that this organism has a haploid chromosome number of 6.
In a diploid chromosomes, the number of chromatids that will be present will be twice of that in haploid.
Since haploid (n) = 6, diploid (2n) will be; 2 × 6 = 12
Somatic cells on the other hand also exhibit diploid number of chromosomes, again it means we will have (2n) = 2 × 6 = 12
In metaphase cell, cells do make sure they complete the S'phase of the cell cycle before cellular division.Therefore, the DNA present in the chromatids in the S'phase actively engage in chromatids doubling, as a result, 24 chromatids (i.e 12 × 2= 24) exists in the metaphase cell.
Answer:
Our alimentary canal undergo a process or a movement called peristalsis, in which the walls continuously move to pass the food downwards. So if you eat hanging upside down, the food would surely move.
Explanation:
- Peristalsis is a series of wavelike muscle contractions that moves food to different processing stations in the digestive tract and the process begins in the oesophagus when a bolus of food is swallowed.
- The muscles of the oesophagus are strong enough to propel food and liquids into the stomach even when hanging upside down although there is a risk of choking
- It is advised that maintaining a correct body positioning during eating is very important for digestion to happen properly and avoid blockage of the airways by food and fluid.
- Leaning your body upright slightly and rounding your shoulders a bit so that your chin is tucked-up is a way of exercising safe chewing and swallowing.
