What are the functions of the male reproductive system? production of semen and urine
production of gametes and hormones
production of progesterone and estrogen
production of urine and hormones

Answers

Answer 1
Answer:

Correct answer: B) Production of gametes and hormones  

The male reproductive system include a number of sex organs that play an important role in the human reproduction. All the male organ are located either on the outside of the body or within the pelvic region.

Male reproductive system includes external genital organs and internal genital organs . The external genital organs consists of penis, scrotum and internal genital organs include epididysis, accessory gland and vas deferens .

The main function of male reproductive system is the production and secretion of male sex hormones like testosterone which is required to maintain male reproductive system. It help in the production and transportation of sperm and discharge them in to the female reproductive system at the time of intercourse.
Answer 2
Answer: The answer here is the second option which is "production of gametes and hormones". Gametes equate to Sperm and the hormones will include testosterone.

Atomic mass is determined by the number of protons plus the number of _____. A. Electrons B. Neutrons C. Charges D. Atoms

Answers

The correct answer is option B that is neutrons.  

The atomic mass refers to the mass of an atom of a chemical element articulated in atomic mass units. It is about the same to the number of protons and neutrons in the atom (the mass number) or to the average number permitting for the relative abundances of distinct isotopes.  

The atomic mass of a single atom of an element is determined by supplementing the mass of protons and neutrons.  

Atomic mass is calculated by the sum of number of protons and the number of \boxed{{\text{B}}{\text{. neutrons}}}

Further explanation:

The smallest particle that is the building block of matter is known as an atom. Most of the space in an atom is empty and its mass is concentrated inside a small region called the nucleus.

Protons, electrons, and neutrons are the three subatomic particles that are present in the atom. The sum of protons and neutrons are called nucleons because these are located in the nucleus of the atom. Electrons revolve around the nucleus in fixed orbital path. The positively charged subatomic particle is called proton. Neutron is a subatomic particle that has no charge. Electron is the negatively charged subatomic particle. The number of electrons is equal to the number of protons in a neutral atom.

An atom is written as _{\text{Z}}^{\text{A}}{\text{X}}, where A is the atomic mass or mass number, Z is the atomic number, and X is the letter symbol of the element.

The total positive charge is known as the atomic number. It is represented by Z and is also equal to the number of protons present in the nucleus of the atom.

Atomic mass is the total number of nucleons within the atomic nucleus. It is also known as the mass number. Protons and neutrons together are known as nucleons because these are located in the nucleus of the atom. So atomic mass is the sum of number of protons and neutrons in the nucleus of an atom. Hence option (B) is correct.
