Which of the following is NOT an accessory gland of the male reproductive system?
Answer:
a. Testosterone gland
Explanation:post protected
Testosterone gland is not an accessory gland of the male reproductive system.
What is Testosterone gland?Testosterone is a hormone that is primarily produced in the testicles in males and in small amounts in the ovaries and adrenal glands in females. It is a vital hormone that plays a critical role in the development of male reproductive tissues and secondary sexual characteristics, such as muscle mass, bone density, and body hair growth.
Testosterone is also essential for maintaining sex drive and overall physical health in both men and women. The production of testosterone is regulated by the hypothalamus and pituitary gland in the brain, which release signals to the testes to produce testosterone.
Certain medical conditions, lifestyle factors, and aging can affect testosterone production and levels, which can have significant impacts on health and wellbeing. Treatment options are available to address testosterone deficiencies and imbalances.

If you throw a ball straight up into the air, when is the kinetic energy the greatest?
Question 4 options:
Right before you catch it after it falls back down.
When the ball reaches the highest point and stops briefly.
Half the distance on the path traveling back down.
Half the distance on the path traveling up in the air.
Half distence on the path traveling up in the air.
Explanation:
When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy
If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.
What is Kinetic energy?Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.
When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.
Therefore, the correct option is D.
