Answer:
Down syndrome
Explanation:
Down syndrome is a genetic disorder that occurs when an abnormal cell division results in an extra copy of chromosome 21. <em>Some symptoms of this syndrome are distinct facial features (small ears, small head, flat face, etc.), short height and even heat defects.</em>

Any illness arising due to spoilage of food that is due to contaminated food, viruses, pathogenic bacteria or parasites that contaminates food is known as food-borne illness.
The large quantity of food can be chilled or heated quickly by dividing and placing the food into small and shallow containers.
Answer:
3.5 percent (3.5%)
Explanation:
In genetics, <em>crossing over</em> or 'recombination' refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes during meiosis I. The map units (m.u.), also known as centimorgans, represent a measure of genetic linkage between genes/<em>loci</em> located on the same chromosome. One map unit (1 m.u.) is equal to a 1 percent chance that two gene/<em>loci</em> (in this case, genes H and K) will be separated during meiosis by recombination. In the example above, it means that among their progeny, 3.5 percent (3.5%) will be recombinant for the two genes (H and K), and 96.5 percent (96.5%) will have the parental combination of these genes.
Answer:
Explanation:
Phototropism is the growth of organism characterize by their response to light stimulus. It occurs mainly in plant and some Algae.
The response of plant to light enable them use energy from light needed for photosynthesis.
Plant Phototropism characterise some plant growth and development such as flowering,fruiting and seedling formation.
Inability of plant to respond to light reduces it ability to photosynthesize and make sugar needed for their activities ,flower and fruits. It reduces it growth and development.
We have positive and negative response. Positive response is the response of plant towards the direction of light while negative response is the response of plant away from light.
