Why do we pee and do we have to do it

Biology

Answer and Explanation:

We pee because our body needs a way to get rid of the excess waste and water in our system. And, yes, we do need to pee. It's as natural as breathing. So, when we drink, what do we do? We pee. Simple.

When you feel the urge to pee and have to sprint to the bathroom in case you can't make it by walking, the brain signals the bladder muscles to tighten, squeezing urine out of the bladder. At the same time, though, the brain signals the sphincter muscles to relax, and so, as these muscles relax, urine exits the bladder through the urethra. When all the signals happen in the correct order, normal urination, or peeing, occurs.

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place. mass of an oxygen-16 atom: 15.
Naya [18.7K]

Answer:

Explanation:

Given parameters:

Mass of oxygen atom = 15.994914amu

Mass of a proton = 1.00728amu

Mass of a neutron = 1.00866amu

Unknown:

Mass defect = ?

From the periodic table, the number of the elementary particles in a neutral Oxygen atom is given below:

           Number of protons = 8

           Number of neutrons = 8

          Number of electrons = 8

Solution

The mass defect examines the difference between the actual mass of an atom and sum of masses of the nucleons.

The mass of an atom is concentrated in the nucleus which contains protons and neutrons. Electrons have little to no weight compared with the nucleons.

    To calculate the mass defect, we first know the mass of the nucleons first:

           1 proton has a mass of  1.00728amu

           8 protons will weigh: (8 x 1.00728)amu = 8.05824amu

For the neutrons:

          1 neutron has a mass of 1.00866amu

          8 neutrons will weigh: (8 x 1.00866)amu = 8.06928amu

Mass of the nucleons = mass of protons + mass of neutrons

                                   = 8.05824amu + 8.06928amu

                                   = 16.12752amu

The mass defect = mass of the nucleons - mass of the atom

                             = 16.12752amu - 15.994914amu

                              = 0.132606amu ≅ 0.13261amu to 5 decimal places

Which does NOT occur in telophase? Cytokinesis is under way. The nuclear envelope is being reconstructed. The centromeres split
Lostsunrise [7]

Answer:

The centromeres split apart

Explanation:

Telophase is the last sage of cell cycle that ultimately result in the formation of daughter cells. The chromosome become more condense in this stage.

The nuclear envelope reconstructed and the cyotkinesis is under way in the telophase. The nucleolus reforms in the telophase. The centromeres are split part in the anaphase stage of the cell cycle.

Thus, the correct answer is option (3).
