Expt. No.
SashulF [63]

Answer:

The process of the formation of Urine starts when the blood enters the kidney and is filtered by the nephrons to separate the water from the larger elements that compound it like blood cells and proteins. Then, they go to the blood, and the elements that passed the filtration membrane go to the renal tubule to be moved to the bladder or be reabsorbed in case they are necessary for the body.

Explanation:

The Urine creation process starts with the blood entering the nephron in the kidneys. Then it is filtrated blocking blood cells and large proteins, making only water and smaller elements pass the filtration membrane. Then, cells and proteins, as well as the elements that couldn't pass the filtration membrane, go back to the bloodstream. While the elements that passed the filtration membrane go to the nephron to enter the renal tubule. In this tube some of the components that can still be used by the body are reabsorbed, the rest continues its journey to the bladder.

The approximate water temperature at a depth of 125 meters would be closest to: (1) 15°C (2) 8°C (3) 13°C (4) 3°C
photoshop1234 [79]

Answer:

(2) 8 ºC

Explanation:

The range of the temperatures from the uppermost layers of the ocean - around 100 to 150 m -, which in this case is 125 m, is not always constant as they fluctuate due to the atmospheric heating and cooling, and also due to seasonal variations.

However, if we base our answer on the table below, we would determinate that the approximate water temperature at a depth of 125 meters is 8 ºC (2). This is because, if we observe, the temperature at 100 m is 12 ºC, while at 150 m is 5 ºC. Therefore, the temperature at 125 m should be higher than 5 ºC and lower than 12 ºC, that is 8 ºC.

a star's brightness if it were a standard distance from earth is its apparent brightness true or false
stepladder [879]

This is false. Absolute brightness is the term used to describe how bright a star would look if it were a standard distance from Earth. Apparent brightness is how bright it would look as far as it currently is from Earth. Hope this was helpful!
