baherus [9]

Coconut milk is a liquid endosperm, and has been found to be a very significant enhancer of growth and proliferation of plant stem cell tissues in the culture. Cytokinins present in the cocnut milk are attributed to this effect. Cytokinins stimulate shoot initiation, root growth, cell division, and leaf senescence.

Answer:

**IF SOMEONE IS EXPERIENCING A MEDICAL EMERGENCY, CALL 911 IMMEDIATELY**

Is someone overdosing? The most important thing is to act right away!

It is rare for someone to die immediately from an overdose – it is usually a slowish process that takes anywhere from a few minutes to a few hours. When people survive, it’s because someone was there to respond.

If someone is overdosing, they will be

1) not breathing and 2) not responsive.

Below are the immediate steps you want to take in the event of an opioid overdose.

If someone is not breathing (skin turning blue/gray, pinpoint pupils, deep gurgling sound) and not responsive, follow these steps. You’ll find more info on each of these steps below.

STEP 1. Stimulate them awake by yelling their name and administering a hard sternum rub to the chest plate.

STEP 2. If you have naloxone/Narcan, use it. Administer one dose every two minutes.

Injectable: Draw up entire vial and inject into thigh muscle (must be muscle’ed to work)

Nasal: Stick the device all the way up one nostril and click the plunger, make sure the device is inserted fully (medication will absorb through the sinuses)

STEP 3. Call 911, explain someone is not responsive and not breathing

STEP 4. Provide rescue breathing

Get the person on their back, tip their head back to straighten the airway, pinch their nose, put your mouth over theirs and form a seal, one breath every five seconds

STEP 5. When the person starts to breathe regularly on their own, roll them into a recovery position on their side

STEP 6. Be gentle with them and yourself afterwards!

 Assessment & Stimulation

If you are unsure if the person is overdosing, there are obvious signs you can assess.

Is the person breathing?

Is the person responsive?

Do they answer when you ‘shake and shout’ their name?

Can the person speak?

How is their skin color (especially lips and fingertips)?

Stimulate the person

If the person is unconscious or in a heavy nod, try to stimulate them awake through verbal and/or physical stimulation.

Verbal Stimulation

Call his or her name and/or say something that they might not want to hear, like “I’m going to call 911” or “I’m going to give you naloxone.”

Sternal Rub – Photo: N.O.M.A.D (Not One More Anonymous Death)

Physical Stimulation

If this does not work, try to stimulate him or her with pain to wake them up.

rub your knuckles into the sternum (the place in the middle of your chest where your ribs meet)

rub your knuckles on their upper lip.

pinch the back of their arm.

If this causes the person to wake up try to get him or her to focus. Can they speak to you? Check their breathing. If this is shallow or the person tells you they have shortness of breath, or chest tightness call 911. Continue to monitor them, especially the breathing and pulse and try to keep him or her awake and alert.

If the person DOES NOT respond to stimulation and remains unconscious or the condition appears to get worse, do NOT try a different or alternative form of stimulation. Treat this as an emergency and call for help!

2. Call for Help!

It is recommended that you call 911 in the case of an overdose because it is important to have trained medical professionals assess the condition of the overdosing person.

Even though naloxone can fix the overdose, there may be other health problems going on. Also, people who survive any type of overdose are at risk of experiencing other health complications as a result of the OD, such as pneumonia and heart problems. Getting someone to be checked out by a medical professional is an important part of reducing the harms associated with overdosing.

What to Say to 911

What to say when calling 911 depends on the local emergency response to overdoses. In every community, it is important to report that the person’s breathing has slowed or stopped, he or she is unresponsive, and give the exact location. If Naloxone was given and it did not work, tell the dispatcher

9 - A group of living things of the same species, living in the same area

dusya [7]

what’s a population? It’s a group of individuals that all belong to the same species. Populations are geographically based; they live in a particular area. But the size or scale of that area can be variable – we can talk about the human population in a city, a state, a country or a hemisphere. Or we can talk about the population of palm trees on just one island in the Indian Ocean, or on all of the islands that make up the Republic of Seychelles, or all of the islands in the Indian Ocean. The person studying or writing about the population gets to decide what scale to use, what is most appropriate for what they want to study or explain. That’s one of the exciting things about science – there’s a lot of freedom in defining the scope and scale of your project, but that means it is also important to explain clearly what scale you are using.

Species are made up of populations. How many populations? It all depends. It depends on how widespread the species is and how small or large the geographic area is. Some species have very limited ranges or distributions, being restricted, for example, to a single island or the top of a single mountain in the whole world. The single population on the island or mountaintop makes up the entire species. From a conservation perspective, such populations are extremely vulnerable – if anything happens to that one population, the entire species will be lost; the species will go extinct. But many species are more widespread. There are populations of moose, for example, in Yellowstone National Park, Maine, Minnesota, Alberta, Manitoba and other U.S. states and Canadian provinces. If you want to know how many moose there are on Earth, you have to know the sizes of all the different populations in all the different locations.

Communities are made up of all the populations of different species in a given area. Why the vague term “in a given area?” Because once again the scale is flexible, determined by the person studying or writing about the community. We might be talking about the community of all the organisms living in the very top or canopy of a single rainforest tree or of all the trees in the forest. What’s most important about the community concept is that it involves multiple populations of all the different species in the given area and how these species interact with each other. Each of the populations is made up of individuals of a particular species, and the individuals interact with each other – with members of their own species (e.g., fighting, grooming, mating, pollinating each other) and with individuals of other species (e.g., hunting them for food, using them as a place to build a nest, growing on them). Community ecologists study the populations in a given area and their interactions. There’s another article in this tutorial about different types of ecological interactions.

That leaves us with the ecosystem level. What’s the difference between communities and ecosystems? When you’re talking about ecosystems, you’re not only looking at all the different populations and species in the given area, but you’re also looking at the physical environment, the non-living or abiotic conditions (language alert: the prefix “a” means “without” and the root word “bio” means life, so abiotic is literally “without life” or in other words, non-living), and not just what they are, but how they impact the organisms, and in some cases how the organisms impact the physical environment. For example, temperature and rainfall patterns influence where different terrestrial species of plants and animals live; some can survive dry desert conditions, others need the high rainfall found in rainforests. But the forests themselves also influence temperature and rainfall patterns. Have you ever noticed on a hot summer day how much cooler and moist it is in the shade of a forest than out in the open? And worms change the structure and composition of soil as they churn through it.

What size is an ecosystem? Guess what – it depends on how big or small the scientist or author wants to define it to be. It could be as small as your backyard, or Walden Pond, or the entire Australian outback. Different sizes or scales will be appropriate for different types of studies, reports and policies. The scientist or author just needs to explain what the size is and why it is appropriate.

here is the other ones as well as population
