Answer:
b prostate gland
Explanation:
The prostate gland's main function is to secrete prostate fluid, one of the components of semen. The prostate is also a common site of cancer.
Explanation:
Protons are positively charged sub-atomic particles that are in the nucleus of an atom and have a relative mass of 1. Neutrons have a neutral charge, meaning they have no charge, and are also in the nucleus of an atom with a relative mass of 1.Electrons are negatively charged particles that orbit the nucleus in electron clouds. They are said to have a relative mass of 0.
For example, a sodium atom is number 11 on the periodic table. The atomic number of sodium tells us the no. of protons contained within its nucleus as well as the number of electrons orbiting. So we can say that sodiun has 11 electrons and 11 protons. To determine the number of neutrons, simply subtract the number of protons from the mass number( found on periodic table)
23-11=12 neutrons
Answer:
Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.
Our sun is a type G main-sequence star.
The temperature of these starts range between 5,300 and 6,000 kelvins and the surface ranges from 0.85 to 1.15 M☉ (solar masses).
