Answer:

Oceans upwelling decreases, reducing levels of nutrient-rich water

Explanation:

Typically, trade winds blow from east to west in the Pacific pushing warm surface ocean waters towards Asia. This causes upwelling of cold ocean currents from the depths of the oceans on the west coast of South America bringing up nutrients from the depths.

During Elnino, however, these trade winds weaken, and predominant winds blow eastwards, reducing this upwelling of colder deeper waters.

When weather conditions are disrupted by El Nino then Oceans upwelling decreases and levels of nutrient-rich water is reduced.

Further Explanation:

The Pacific Ocean is the Earth's largest and deepest Oceanic division that stretches from Arctic Ocean towards North to Southern Ocean towards South. It is also bounded Australia and Asia in the Western side and America on the eastern side. It covers consists of the Earth's 46% total surface water. The imaginary line Equator that splits the Earth Into two hemispheres passes through it centrally and divides the Earth into the Southern hemisphere and Northern Hemisphere.

Warm current in the Pacific Ocean is caused due to change in the temperature of the water that is called El Nino. It is related to the belt of warm ocean water developed in the central and eastern-central equatorial Pacific that includes the area of South America's Pacific coast. El Nino is conveyed by western Pacific high air pressure and eastern Pacific low air pressure. The countries that are under the developing stage get most affected by it, particularly those countries that depend on fishing and agriculture.

What is special about nitrogen, and what is its main function in the atmosphere

inna [77]

Nitrogen is the most abundant of the gases present in the atmosphere. 78 percent of the atmospheric air comprises of nitrogen, oxygen makes up for 21 percent and all other gases make up for the remaining one percent. Oxygen is a highly flammable gas and in the absence of nitrogen it would not have been possible to utilize this atmospheric oxygen, hence the presence of nitrogen reduces its flammability and also neutralizes the toxicity of other gases. Another way to explain this question is - The vital thing about Nitrogen is that it gives air to people to take in, 78% of the air we take in is Nitrogen and just 21% is oxygen, 1% is different gasses. On the off chance that the air was unadulterated oxygen then everything would be to a great degree flamable, and it would likewise be hurtful to people. Nitrogen assumes a vital part in our lives. Oxygen can be poisonious on the off chance that it was the main gas noticeable all around... Nitrogen is too much critical, else we would all die.... Also, I seek oxygen stays 21% after it can be hazardous. Definitely, you ought to realize that Nitrogen can likewise be risky in A few ways, you can look that up and take in more about it, however at this moment we're looking at something else and I would prefer not to be insignificant by any stretch of the imagination, so I'll simply adhere to the Inquiry on the point as apose to the Entire whole theme. I know I have addressed your inquiry, and I believe this was useful.

The La Brea Tar Pits in Los Angeles are the site of millions of fossils from the ice age. Woolly mammoths, giant sloths, dragonf

TiliK225 [7]

Answer:

Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits

Explanation:

La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.

Why insect mouth part is important for insect pest control?

Maslowich

Answer:

Insects with rasping/sucking mouthparts actually rasps or scrapes the surface of plant tissue (such as leaves or petals) and sucks up the fluids that ooze from the damaged area of tissue. Examples of pests with rasping-sucking mouthparts include thrips and mites. Thrips prefer to feed on succulent plant tissues.

Helppppppp plz thx........

Answer:

1) aa- affected

2) Aa- unaffected carrier

3) aa- affected

4) aa- affected

5) Aa - unaffected carrier

6) Aa- unaffected carrier

7) aa- affected

8) aa- affected

9) Aa- unaffected carrier

10) aa- affected

11) Aa- unaffected carrier.

This trait is recessive.

The F1 generation has a 50/50 chance of having unaffected offspring.

Explanation:

1) Given

2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier

3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)

4) They are also shaded in, so they have to have the trait

5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

6) Same reasoning as #5

7) This is shaded in, the box has to have the trait

8) Shaded in = has the trait/affected

9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

10) Shaded in = has the trait/affected

11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.

If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.
