Answer:
The human brain is the most complex organ in the body. This three-pound mass of gray and white matter sits at the center of all human activity—you need it to drive a car, to enjoy a meal, to breathe, to create an artistic masterpiece, and to enjoy everyday activities. The brain regulates your body's basic functions, enables you to interpret and respond to everything you experience, and shapes your behavior. In short, your brain is you—everything you think and feel, and who you are.
Explanation:
How does the brain work?
The brain is often likened to an incredibly complex and intricate computer. Instead of electrical circuits on the silicon chips that control our electronic devices, the brain consists of billions of cells, called neurons, which are organized into circuits and networks. Each neuron acts as a switch controlling the flow of information. If a neuron receives enough signals from other neurons that it is connected to, it fires, sending its own signal on to other neurons in the circuit.
The brain is made up of many parts with interconnected circuits that all work together as a team. Different brain circuits are responsible for coordinating and performing specific functions. Networks of neurons send signals back and forth to each other and among different parts of the brain, the spinal cord, and nerves in the rest of the body (the peripheral nervous system).
How do drugs work in the brain?
Image showing a neuron. The neurotransmitter and receptor are called out to show how signals are sent, received and processed through the neuron.
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body. This allows the drugs to attach onto and activate the neurons. Although these drugs mimic the brain’s own chemicals, they don’t activate neurons in the same way as a natural neurotransmitter, and they lead to abnormal messages being sent through the network.
Other drugs, such as amphetamine or cocaine, can cause the neurons to release abnormally large amounts of natural neurotransmitters or prevent the normal recycling of these brain chemicals by interfering with transporters. This too amplifies or disrupts the normal communication between neurons.
What parts of the brain are affected by drug use?
Drugs can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug use that marks addiction. Brain areas affected by drug use include:

These cells are located in the semicircular canal and vibrate in response to sound. These cells can become damaged due to loud noises and sometimes will die resulting in hearing loss. a vestibule hair cells b cochlea cells c auditory nerves d sensory hair cells
Answer: The correct option is D (Sensory hair cells)
Explanation:
The ear is one of the sense organs recognised in humans which helps in hearing and for balance maintenance. There are different parts of the ear which includes:
--> the outer ear,
--> the middle ear and
--> the inner ear.
The semicircular canals are made up of three interconnected tubes which are located in the inner part of the ear. It consists of sensory hair cells which vibrates in response to sound.
Sensory hair cells serves as receptors of both auditory and vestibular systems, therefore are necessary for hearing and balancing. These cells can become damaged due to loud noises and sometimes will die resulting in hearing loss.

Health: How can the failure to take antibiotics properly pose a risk to other people's health?
Answer:
Antibiotics will hold back a lot of stuff.
Explanation:
I said that wrong, so I'll try to explain it better. You know when you'd scrape your knee or get a cut and you'd put some antibiotic gel on it so it wouldn't get infected? Antibiotics also work the other way around, meaning they stop the spread of sickness by nullifying it and stopping it from multiplying. So if you don't take the proper antibiotics you'll have a higher chance of spreading it to other people.

I came out as gay to my close group of friends and they are really supportive, what are some of your peoples come out stories?
Answer:
Explanation:
You already know who you are. Should you tell other people?
It's normal to wonder about coming out (telling people that we're gay, lesbian, bisexual, or transgender). On the one hand, it might feel like a relief: Friends might be asking questions that you avoid or have trouble answering. On the other hand, you probably think about how your world could change: How will people react? Will the people you tell spread the word to someone you'd prefer didn't know?
There are lots of reasons why people choose to come out. Here are a few:
They're ready to start dating and want close friends and family members to know.
They don't want people making assumptions about them or gossiping.
They're tired of hearing other people use stereotypes or negative labels.
They feel like they're living a lie or not acting true to themselves and want to feel accepted for who they really are.
There are also plenty of reasons why people decide not to come out, such as:
They're not yet sure about who they are or how they feel. They're still trying to figure things out for themselves.
They feel that topics like sexual orientation or gender are private and see no reason to talk about them.
They're afraid they'll face bullying, harassment, discrimination, or even violence.
Their families don't know, and they worry about what might happen if parents or siblings find out.
Coming out can be a little trickier in our teens because we depend on parents or other adults for our care and well-being. Some people live in places where being LGBT is accepted. It's easier for them to come out because they're more likely to get support from family and friends. Others realize their family or social environments aren't supportive and choose to wait until they're living on their own.
Most people come out gradually. They start by telling a counselor or a few close friends or family. A lot of people tell a counselor or therapist because they want to be sure their information stays private. Some call an LGBT support group so they can have help working through their feelings about identity or coming out.
When Friends Influence Us
As kids, our lives center around family. But in middle school and high school, we start exploring new interests outside our families. We deepen our bonds with friends. This is a natural step in discovering who we are and becoming more independent.
These new friendships and experiences can be a lot for our brains to take in. Our minds might look for shortcuts by sorting people into groups. It's one reason why people form cliques. We might find ourselves thinking stuff like: "Brian is a real theatre kid. I like being around him because he's so creative and open to trying new things." Or, "Sara's so nerdy. She'll always be my friend from elementary school, but we don't have much in common anymore."
Putting people into categories is a normal part of figuring out where we fit in and what's important to us. But there are downsides to this kind of thinking: It leads us to assume things that might not be true.
If friends make assumptions about your sexuality, they might encourage you to come out — even if you're not sure yourself. Your friends might mean well. But they also could be trying to categorize and understand you, even if they don't realize they're doing it. You might feel pressured. You might think, "I'm not really sure, but maybe she knows me better than I do." Or, "He's being really supportive. I'm sure he'll be there for me if things get tough."
It's easy to get swept along by what others think you should do — whether those people are friends or well-meaning adults. But the truth is, no one knows better than you. Coming out is a very personal decision. You have to be ready.
Deciding to come out requires a lot of thought and planning so you can feel in control no matter what happens: Will the friend who says he's there for you stand by you if you get bullied? If you ask a teacher to keep your information private, what will you do if word gets back to your family?

Select all that apply. Human papillomaviruses cause: genital cancers HIV genital warts dementia
Answer:
genital warts
genital cancers
Explanation:
Human Papillomavirus (HPV) is a sexually transmitted disease that is common around the world. These causes genital warts that may or may not go away on its own. It doesn't necessarily mean that having an HPV can immediately lead to genital cancer like cervical cancer. Thus, it is very important to have a Pap Smear every 3 years if you're sexually active in order to detect cancer in the cervix at an early stage.
HIV (Human Immunodeficiency Virus) is also a sexually transmitted disease but it is not related to HPV.
Remember that HPV may also cause cancer in the throat, head and neck (other than the genital area).
