What process signals the end of one cycle and the beginning of another in the menstrual cycle

Answers

Answer 1
Answer: The menstrual cycle is the set of physiological phenomena, occurring most often periodically (approximately one month), which prepare the body of the woman for a possible fertilization.
The process signal of the end of one cycle and the beginning of a new one is menstruation which is explained by the release of the unfertilized ovule with the placenta precursor (which is a blood).
In the case of fertilization, the menstrual cycles are "paused", and "resumed" after the childbirth.

Explain how artificial erosion is a problem even though erosion occurs naturally

Answers

The methods that stimulate artificial erosion may cause numerous negative problems like climate change, deterioration of the quality of the soil, soil infertility, etc.

What is Erosion?

Erosion may be characterized as a type of geological process through which soil and its components are worn away and transported by natural forces such as wind or water. In a more simple sense, erosion is the migration of pieces of the earth's surface from one place to another by various means.

Erosion whether it is artificial or natural causes various negative impacts on the earth's surface. Artificial erosion is caused by the construction of roads, urbanization, deforestation, etc. All these factors ruin the entire biodiversity present on the earth. Finally, makes an environment unbalanced with respect to the resources available.

Therefore, the methods that stimulate artificial erosion may cause numerous negative problems like climate change, deterioration of the quality of the soil, soil infertility, etc.

PLEASE HELP!!!!! Explain how infection might spread, how people fight off diseases, and why malnutrition can lead to the spread of disease in the time immediately following a natural disaster.

Answers

Answer:

When people are unable to access their homes due to a natural disaster, a(n)  

✔ shelter-in-place plan

advises them where to stay.

To lessen the likelihood of a wildfire spreading, a(n)  

✔ containment plan

might be enacted.

A(n)  

✔ evacuation plan

explains what people should do immediately following a disaster.

Explanation:
Infections spreading:
Infections are caused by bacteria, virus and other microscopic organisms. They spread through droplet (sneezing etc), they can spread through blood contact (used needles that are re-used), direct physical contact (skin infections), stool (germs from excretion) and contaminated objects.

How people fight off disease:
We have antibodies in us that fight off invading cells that contain foreign bodies. Our immune system secretes these antibodies and these antibodies will fight off the infection. The time it takes for the infection to be eradicated depends on the strength of your immune system and whether you have been vaccinated.

Natural disaster:
Natural disaster such a tsunami's and earthquakes can contaminate water supplies. In tsunami's the water from the sea will go into the drinking water which isn't safe because it could cause diseases such as cholera to spread. Earthquakes disrupt sewage structures. If these are broken, water regulation would not be as good so we end up drinking dirty water, which could also be contaminated with cholera!

Identify three of the seven common neurotransmitters and the functions of each. Then describe what each neurotransmitters controls or regulates in the body.

Answers

Answer:

One common neurotransmitter is dopamine. It is an excitatory neurotransmitter that is involved in movement, learning, attention, and emotion. GABA is another common neurotransmitter, and it is a major inhibitory neurotransmitter. It is involved in anxiety, arousal, and sleep. Glutamate is a major excitatory neurotransmitter, and it is involved in learning and memory.

Acetylcholine: Serves as a messenger between each motor neuron and skeletal muscles, which accounts for its role in helping to control skeletal muscles.

Serotonin: Affects sleep, hunger, mood, and arousal; connected to aggression and abnormal behavior

Norepinephrine: Helps control arousal and alertness; helps in regulating mood

Endorphins: Major excitatory neurotransmitter; linked to memory and learning processes; released in response to pain and intense exercise

Explanation:
