Answer 1

In summer,the body loses water in the form of sweat. So secondary capillaries try to absorb more water from the glomerular filtrate allowing less water to be sent out as urine.

In winter,we don't lose water in form of sweat. So,the secondary capillaries absorb less water from the glomerular filtrate allowing more water to be sent out as urine.
