Give two examples of how the endocrine system is important to the process of reproduction in humans?
Pepsi [2]
It wakes up the hormones in your body so you can reproduce in the first place, and it also helps to mature and prepare your body, and your cells, so it is able to reproduce. By waking up those hormones, your body is able to perform reproductive processes

How does semi-conservative replication help prevent mutations during DNA replications?
Llana [10]

DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.

Provide brief overview of the nervous system and its role in the maintenance of homeostasis.
Alona [7]
Explanation:

The nervous system has two major anatomical subdivisions:

Central Nervous System: Composed of the brain (inside the skull) and the spinal cord (inside the spinal column).

The brain and spinal cord are responsible for processing and integrating the various sources of information to allow us to develop a response. Therefore, the main function of the somatic nervous system is to connect the Central Nervous System with the organs and skeletal muscle to carry out our daily functions.

Peripheral nervous system: it is everything that is outside the bone cavity and is formed by the nerves and nerve ganglia that extend outside the central nervous system.

The peripheral nervous system has a somatic component, which is associated with the voluntary control of body movements through the use of skeletal muscles. This means that it is responsible for all the functions that we are aware of, including the movement of our arms, legs, and other parts of our body.

On the other hand, the autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiological processes. These processes include heart rate, blood pressure, breathing, digestion, and sexual arousal. The autonomic nervous system contains three divisions: sympathetic, parasympathetic, and enteric.

Due to the above relationships and anatomical subdivisions we can say that the nervous system is responsible for regulating and maintaining homeostasis. In fact, through its receptors, neurotransmitters, nervous inputs, and outputs, the nervous system keeps us in touch with our environment, both external and internal.

We can conclude that the correct answer is:
