How could tides and ocean currents move plastics around the ocean?

1 answer:

6 0

The plastic trash gets transported all through the planet with the help of ocean currents. The term Great Pacific Garbage Patch was first named by Captain Charles Moore. He found that huge intact substances like cups, bottles, boxes, bags, and fishing nets, and other millions of smaller pieces of plastic over an estimated region covering about 650000 to 16000000 square kilometers.

The garbage patches are witnessed in the oceans of the world wherever there is gyre. The gyres refer to the enormous circulating regions of water comprising the prime surface currents of the globe, mediated by the existing winds. The plastics would have got caught up in a gyre and would have been ended up in a region, known as the garbage patch.

The currents present in the gyre take in the floating substance from around the periphery and trap it in the center. The currents and waves dissociate the plastic components into smaller pieces, however, it never goes away, and gets transported to different regions with the help of currents.

The ocean currents mediate and transport useful things like organic nutrients, heat energy, and marine species from one location to another of the planet. However, at the same time, they can also transport other unnecessary floating things like plastic garbage.

The plastic, mainly the larger pieces that float on the surface are transported at a faster rate than the water present beneath it, this is because the wind that moves the current also moves the plastic. In this sense, the plastic is flowing freely all over the ocean surfaces of the globe.

Correctly order the steps in which blood travels through the heart from the time it enters from the systemic circuit until it re

Sav [38]

Answer:

Steps in which blood travels through the heart from the time it enters from the systemic circuit until it returns to the systemic circuit are:

Aorta receives the oxygenated blood from the left ventricle.And gives it to systemic arteries.
Cells recieve the oxygenated blood and give out carbon dioxide laden blood.
The superior and inferior venacava bring deoxygenated blood to the right atrium.
The deoxygenated blood then moves into the right ventricle.
Deoxygenated blood reaches lungs through Pulmonary artery.
Left Atrium recieves blood from lungs through pulmonary veins..
Oxygenated then moves into Left Ventricle.
Aorta recieves the blood from the Left ventricle

Explanation:

There are Two types of circulation in human body; the pulmonary circulation and the systemic circulation.

In Pulmonary circuit the blood is pumped into the lungs from the right ventricle to the lungs through pulmonary arteries. In this circulation the blood gets oxygenated.

In Systemic circuit the oxygenated blood from the lungs is pumped into aorta by the Left ventricle so that it can reach the body tissues,

This circuit also brings deoxygenated blood from the body to the Right atrium of the heart.

Blood enters the systemic circuit when Aorta receives the oxygenated blood from the left ventricle.

The oxygenated blood then flows into the systemic Arteries and reaches the body tissues.

Cell consumes the the required oxygen and nutrients then adds carbon dioxide, hormones and waste material to the blood.

The systemic veins collect the deoxygenated blood.
The deoxygenetated blood from upper half of the body is carried by superior vena cava and the blood from lower half of the body is carried by inferior vena cava.
Both superior and inferior vena cava bring the blood to the right Atrium.
From the right atrium, the blood moves into right ventricle through tricuspid valve.
The Pulmonary artery carries the blood from right ventricle to the lungs.
After the carbon dioxide diffuses out and oxygen is added, the blood is taken up by pulmonary vein.
The Pulmonary vein brings the oxygenated blood to the left atrium of the heart.
The blood then moves into the left ventricle through the bicuspid valve.
The left ventricle then pumps the blood into the Aorta through aortic valve returning the circulating blood to the systemic circuit

narvez 5. Everyone in Dobby's family has a long nose and they brag that they are from a purebred line. Viola has a stubby nose.

mote1985 [20]

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

<h3 /><h3>SCENARIO 1 ⇒ long nose is the dominant trait</h3>

Let us say that

L is the dominant allele and codes for long nose

l is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nose

ll ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals) LL x ll

Gametes) L L l l

Punnett square) L L

l Ll Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long nose

There is 0% chances for a child to have a stubby nose

These children are not purebred

**********

<h3>SCENARIO 2 ⇒ Stubby nose is the dominant trait</h3>

Let us say that

S is the dominant allele and codes for stubby nose

s is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nose

ss ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals) SS x ss

Gametes) S S s s

Punnett square) S S

s Ss Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby nose

There is 0% chances for a child to have a long nose

These children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals) Ss x ss

Gametes) S s s s

Punnett square) S s

s Ss ss

F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

There is 50% chances for a child to have a stubby nose

There is 50% chances for a child to have a long nose

These children are not purebred
