Answer: Lydia's answer is correct.

Explanation:

The solution used by Lydia is:

4/5 × 10 = 4 × 1/5 × 10

= 4 × 10/5

= 4 × 2

= 8

The above solution by Lydia is correct.

Given the question, 4/5 × 10, this will be:

= 4/5 × 10/1

Let's multiply the numerator first, this will be: = 4 × 10 = 40

The denominator will be: = 5 × 1 = 5

Therefore, 4/5 × 10/1 = 40/5

Now when we divide 40 by 5, we will get 8. Therefore Lydia is correct.

How does a scientist get the corrected version of a gene into the cells of a gene therapy patient?

Angelina_Jolie [31]

Answer:

In order to insert new genes directly into cells, scientists use a vehicle called a “vector” which is genetically engineered to deliver the gene. Viruses, for example, have a natural ability to deliver genetic material into cells, and therefore, can be used as vectors.

Draw two amino acids connected via a dehydration synthesis reaction.

sergejj [24]

Answer:

Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O

Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O

Explanation:

Dehydration

In chemistry, a dehydration reaction is one that involves the loss of water. In organic synthesis, where an acid is often used as a catalyst, there are numerous examples of dehydration reactions: Conversion of alcohols to ethers: 2 R-OH → R-O-R + H2O Conversion of alcohols to alkenes: R-CH2-CHOH-R → R-CH=CH-R + H2O Conversion of carboxylic acids to acid anhydrides 2 RCO2H → (RCO)2O + H2O Conversion of amides to nitriles: RCONH2 → R-CN + H2O

What are the 2 GENERAL CATEGORIES of illegal psychoactive drugs that<br> exist?

madreJ [45]

Answer:

There are actually 7 categories..

(1) Central Nervous System (CNS) Depressants

CNS depressants slow down the operations of the brain and the body. Examples of CNS depressants include alcohol, barbiturates, anti-anxiety tranquilizers (e.g., Valium, Librium, Xanax, Prozac, and Thorazine), GHB (gamma hydroxybutyrate), Rohypnol, and many other anti-depressants (e.g., Zoloft, Paxil).

(2) CNS Stimulants

CNS stimulants accelerate the heart rate and elevate the blood pressure and "speed-up," or over-stimulate, the body. Examples of CNS stimulants include cocaine, "crack" cocaine, amphetamines, and methamphetamine ("crank").

(3) Hallucinogens

Hallucinogens cause the user to perceive things differently than they actually are. Examples include LSD, peyote, psilocybin and MDMA (Ecstasy).

(4) Dissociative Anesthetics

Dissociative anesthetics include drugs that inhibit pain by cutting off or dissociating the brain's perception of the pain. PCP, its analogs, and dextromethoraphan are examples of dissociative anesthetics.

(5) Narcotic Analgesics

Narcotic analgesics relieve pain, induce euphoria, and create mood changes in the user. Examples of narcotic analgesics include opium, codeine, heroin, demerol, darvon, morphine, methadone, Vicodin, and oxycontin.

(6) Inhalants

Inhalants include a wide variety of breathable substances that produce mind-altering results and effects. Examples of inhalants include Toluene, plastic cement, paint, gasoline, paint thinners, hair sprays, and various anesthetic gases.

(7) Cannabis

Cannabis is the scientific name for marijuana. The active ingredient in cannabis is delta-9 tetrahydrocannabinol, or THC. This category includes cannabinoids and synthetics like Dronabinol.

When checking a conscious adult victim, you should interview bystanders and the victim and then?

Tpy6a [65]

You must then check the person from head to toe.

You can start looking for additional problems that could require treatment if the individual is aware and doesn't have any ailments that pose a life threatening concern.

Gently tap the individual to see whether they are cognizant, then inquire as to their well-being. If you don't get a response, there can be a problem that could endanger your life. A responsive individual who can talk or weep is one who is cognizant, breathing, has an unblocked airway, and has a pulse.

Two fundamental phases are involved in checking a conscious person who does not now face a life-threatening situation: interviewing both the person and bystanders, and checking the person from head to toe.

When splinting a possible fracture of the foot, it is most important for the emt to?

mario62 [17]

Leave the toes exposed.

Splinting, immobilization, or both are recommended for any suspected fracture (broken bone) or dislocation. A strong splint effectively reduces discomfort and helps to stop future damage. Splints can be purchased already manufactured or can be created using simple supplies.

One may, for instance, use a foam sleeping pad, boards, layers of cardboard, or branches. Bandanas, climbing webbing, shredded shirts, jeans, or other garments can be used as wrapping materials for the splint.

To secure the splint, these materials should fully encircle the affected extremity. However, they shouldn't be too tightly wrapped to restrict blood flow.
