Answer:
To generate haploid cells.
Explanation:
Previous to the first meiotic division, the genetic material duplicates, giving as a product two diploid cells. Then, these two diploid cells (it means, with chromosome pairs) will divide in the second meiotic division, giving rise to four haploid cells (two each). The gametes, sperm and eggs, should be haploid, so after fertilization they can form a normal, diploid cell.

Answer:
True
Explanation:
This statement is true. Medical researchers at Harvard and Stanford universities found that leading a sedentary lifestyle (sedentary meaning minimal exercise with little movement) leads to a higher risk of health complications (which can be more prevalent in older age).
This finding strongly recommends that middle-aged people should undertake some form of regular exercise so as to not fall into the category of "sedentary".

worsen over time, although the rate at which the disease growths varies.
The stage 1 of this disease is not detectable and
no memory problems or other symptoms of dementia are palpable, it is because changes in the brain associated to Alzheimer's
begin years before any signs of the disease arise. Stage 2 in which Bruno is experiencing
