Answer:

Sacroiliac joint is the slightly movable articulation between the sacrum and posterior portion of the ilium.

Explanation:

Sacroiliac joint is also known as SKJ, and is a hip socket that lies on the bones of the pelvis. It is connected by strong ligaments and is one of the very strong joint that supports the weight of upper body.

Sacrum is the element that supports the spine in human body. This sacrum is further supported by the ilium on both sides.

How do the products of glycolysis and krebs cycle relate to the electron transport chain?

Snezhnost [94]

During the process of glycolysis and krebs cycle (which is also known as tricarboxylic acid (TCA) cycle or citric acid cycle), there is breakdown of large molecules to product smaller molecules and energy including ATP.

So the answer to this would be:

Glycolysis and Krebs cycle produce the molecules that shuttle electrons to the electron transport chain

The sperm-containing pollen grains of seed plants are dispersed by wind or animals to fertilize egg cells. Why is this type of s

Tom [10]

Answer:

Water is not required for the fertilization.

Explanation:

The plants can reproduce by the means of asexual reproduction and sexual reproduction. The pollen grains and egg cell fertilize with each other in the sexual reproduction.

The seedless vascular plants and non vascular plants required the means of dispersal for their fertilization. Their egg cell fuses with the pollen grains that are dispersed by animals or wind. Water is not required for the fertilization of the vascular plants.

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
