Based on the concept of the global conveyor belt, what happens to ocean water as it moves from Antarctica to the equator?
marta [7]

What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.

<h3>Concept conveyor belt </h3>

The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.

As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.

Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is  It becomes less dense and rises to the surface.

Answer:

Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.

Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.

Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.

"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

If you think of the earthworm body plan as a drinking straw within a pipe, where would you expect to find most of the tissues th
Otrada [13]

Option (A) lining the straw is correct.

<h3>What is the anatomy of Earthworm?</h3>
  • An earthworm is a terrestrial invertebrate and a member of the phylum Annelida.
  • They have a tube-within-a-tube body structure, corresponding external and internal segmentation, and typically include setae on each segment.
  • They can be found wherever the soil, water, and temperature permit.
  • The body of an earthworm is composed of a digestive tube and a thick cylindrical muscular tube that forms the body.
  • The body is divided into segments, and furrows on the surface of the body serve as markers for the segment boundaries.
  • The top of the first segment, which encloses the mouth, is a lobe made of muscle and flesh.

HELP PLEASE!!! ASAP I NEED QUICKLY!! DBA List the helpful interactions. List the harmful interactions.
Svetach [21]

1. Symbiosis is the interaction between two different living organisms living together to survive.

2. Parasitism is the relationship between two species of plants or animals in which one benefits at the expense of the other, sometimes without killing the host organism.

Example: Tapeworms attach themselves to the insides of the intestines of animals.They get food by eating the host's partly digested food, depriving the host of nutrients. Another example is fleas. they harm their hosts, by biting their skin, sucking their blood, and causing them to itch.

3. A predator is an animal that preys on other animals, usually for food.

Example: A lion or a bear.

4. The definition of prey is where one organism, the predator, kills and eats another organism.

Example: The prey to a lion would be a zebra, and the prey to a bear would be a fish.

5. Mutualism is where two different species live together to survive at each others advantage.

Example: Oxpeckers and rhinos.

6. Commensalism is where one organism benefits and the other is not harmed or benefited.

Example: Barnacles and Whales.

7. Predation helps keep herbivores from growing into too large of crowds, and predation keep the population of animals in general in check.

8. Competition both within and between species is an important topic in ecology, especially community ecology.

9. This is in your own words :)
