Answer:

Heterozygous = When the offspring inherits two different alleles

Probability = The mathematical chance that something will happen

Trait = Characteristics of an organism that makes it unique

Dominant = The allele that always shows up and hides the weaker allele

Recessive = The allele that is always masked in the presence of the stronger allele

Heredity = The passing of traits from parent to offspring

Hope this helps!

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.

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

<u>Nasal</u>: 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!

<u>  Assessment & Stimulation</u>

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.

<u> </u><u>Verbal Stimulation </u>

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)

<u>Physical Stimulation</u><u> </u>

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.

<u>What to Say to 911</u>

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

Histones are essentially identical in sequence/structure in all eukaryotic organisms from yeast to plants to animals. What does
xxTIMURxx [149]

Answer:

It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals

Explanation:

Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.

Small, isolated populations of collared lizards remain in glades of desert-like habitat scattered throughout the oak-hickory for
dusya [7]

Answer:

Option A

Explanation:

Options

A. most populations were fixed for a single genotype, but genotypes varied among populations

B. average heterozygosity was declining steadily over time

C. individual populations were polymorphic for several loci and most populations were genetically similar to one another

D. all populations were fixed for the same allele at each locus studied

Solution

As per the study conducted by Templeton, it was found that human affect the biodiversity at all biological levels such as genetic, ecosystem, species etc. and behind genetic variation two important factors are genetic drift and gene flow.  

Both the gene flow and genetic drift produce opposite results as genetic drift increase variation with in the species but decrease variation with in the local population and the opposite of this happens in gene flow.  

Genetic drift has actually lead to speciation of collared lizards  among themselves for a specific genotype

Hence, option A is correct
