Answer: The correct answer to the question is option D

APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

Explanation: To answer the question effectively,let's look at the options critically and the effects it will have on a bandaged lacerated elbow that still has blood soaking through the dressing and bandage.

A) Remove the dressing and bandage and start over again with a tighter bandage.

This is a big NO when it comes to wound dressing and care because removing the dressing and bandage will impair the blood clots that must have formed in the lacerated site,this blood clots helps to control the bleeding so when the bandage and dressing is removed,the blood clot will be distorted which will make the wound to start bleeding again.

B) Apply a tourniquet around the wrist.

Application of tourniquet is the last resort in control of bleeding,it is only employed when other measures to control the bleeding has been applied but proved abortive so application of tourniquet is not the right and appropriate measure to be taken at this time.

C) There is nothing else you can do.

This can be termed an act of negligence and its not expected of a healthcare provider,leaving the victims lacerated elbow to be soaking of blood through the dressing and bandage will cause the victim to loose much blood and this might result to shock.(hypovolemic shock)

D) APPLY ADDITIONAL DRESSINGS AND BANDAGES,KEEP APPLYING PRESSURE,LIFT ARM ABOVE THE HEART.

This is the right and most appropriate measure to be taken in the case of a laceration or wound that has blood still soaking through the wound and dressing. The goal is to apply more pressure inorder to maintain homeostasis (control the bleeding).

The arm should also be lifted above the heart to decrease the flow of blood,improve venous return and prevent obstruction of a blood vessel as a result of a blood clot. (thromboembolism).

After the measures has been ensured,the victim should be closely monitored for any skin discoloration (blueish discoloration especially of the extremities),signs indicative of shock,faster breathing or slower breathing and restlessness.

Answer:

La vacuola es el término correcto

(The vacuole is the correct term)

Explanation:

Las vacuolas son burbujas de almacenamiento que se encuentran en las células. Se encuentran tanto en células animales como vegetales, pero son mucho más grandes en células vegetales. Las vacuolas pueden almacenar alimentos o cualquier variedad de nutrientes que una célula pueda necesitar para sobrevivir. Incluso pueden almacenar productos de desecho para proteger el resto de la celda de la contaminación.

(Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.)

What nitrogen compounds are in the nitrogen cycle?
PSYCHO15rus [73]

Answer: In the atmosphere, nitrogen exists as a gas (N2), but in the soils it exists as nitrogen oxide, NO, and nitrogen dioxide, NO2, and when used as a fertilizer, can be found in other forms, such as ammonia, NH3, which can be processed even further into a different fertilizer, ammonium nitrate, or NH4NO3.

Question 1(Multiple Choice Worth 3 points)
shepuryov [24]

Answer:

1. It involves multiple trials

2. 2 red: 2 white

3. Process 1 describes cloning and process 2 describes artificial selection

4. Furry Feet

5. Large scale insulin could be produced in relatively lesser time

6. A lowercase letter

7. 0%

8. rr

9. 50%

10. The allele for white flowers is recessive in the pea plant

Explanation:

1. Repetition, this means to do over and over. This would involve multiple trials and this is done to test the reliability of the results and determine if the hypothesis holds true or not.

2. If you put your cross in a Punnett square it would look like this:

      R    r                            

r     Rr   rr                          

r     Rr   rr

Based on your problem: R = red; r = white

If the genotype would have a dominant allele (R), then the dominant trait will come out, if it has only recessive alleles (r) then the recessive trait will come out. So as you can see there are 2 red and 2 white. So the ratio would be 2:2 or 1:1.

3. Process 1 is considered as cloning, and to be more specific, reproductive cloning. The aim of this is to produce an offspring that has the same genetic make up as the original or parent organism. Process 2 is an example of artificial selection. This is also known as selective breeding where breeders choose certain traits to pass on to the off springs by selecting the organisms that have the traits desired.

4. Furry feet of polar bears provide them extra traction when they walk on snow. The fur also provides extra warmth. They also have foot pads on the soles of their feet that help them as well. Together, polar bear have something that works like snow boots.

5. Large-scale insulin could be produced in relatively lesser time because bacteria reproduce through asexual means. They produce copies of themselves that are genetically identical. An advantage of asexual reproduction is the process occurs in a much faster rate. With that said, insulin supply would increase, which will help many diabetic patients.

6. Recessive alleles in a genotype are represented by a lowercase letter. On the other hand, dominant alleles are represented by a capital letter. Squares and circles are used in pedigree charts to represent the whole genotype of an organism for a specific trait.

7. The answer would be 0% because cystic fibrosis is a RECESSIVE gene disorder. For it to be expressed or observable in an individual , t<u>hey should have two recessive alleles</u>. As you can see in the end result, none of the offsprings have 2 recessive alleles. The genotype Aa, has a recessive allele, but it will not be expressed because the dominant trait will mask it.

8. When we talk about homozygous, this means the alleles are the same. And when you say heterozygous, this means that the organism would have a dominant and recessive allele. the recessive llele is represented by a lowercase letter. So if the organism is homozygous recessive, the genotype would have two lowercase letters. (rr)

9. The scenario shows the genotype is pp. This means that the pea plant is homozygous recessive. As explained before, recessive traits are represented by lowercase letters. So this would mean that the white color is a recessive trait. The answer would then be the allele for white flowers is recessive in the pea plant.

10. Mitosis and meiosis are both forms of cell division. Mitosis produces daughter cells that are exactly the same as the parent cell, while Meiosis produces daughter cells that are different. They produce what we call haploid cells, which has only half the chromosomes of the parent cell. Gametes or sex cells are produced through meiosis, while body cells are produced through mitosis.
