Abstract -

The rapid increase of human population is putting an incredible strain on our environment. While developed countries continue to pollute the environment and deplete its resources, developing countries are under increasing pressure to compete economically and their industrial advancements are damaging as well. The demands that this growth places on our global environment are threatening the future of sustainable life on earth. One of the largest environmental effects of human population growth is the problem of global warming. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate. Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water. The growth of population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems that must be addressed in order to ensure that life on earth will be sustainable throughout the next century.

what is the purpose of motor nerve varicosities as they relate to smooth muscle?

Answers

Neuroeffector junctions are varicosities where motor neurons release neurotransmitters to non-neuronal target cells.  These junctions can be observed along the axon.

The motor nerve varicosities RELEASE neurotransmitters onto smooth muscle cells.

There are many varicosities along the axons of the neurons that feed smooth muscle cells.

When autonomic neurons are stimulated, varicosities release neurotransmitters along their axons.

These neurotransmitters then diffuse through the interstitial fluid to interact with receptors in the smooth muscle cells.

how does your body acquire the oxygen the cells in your body need to function?

Answers

Answer:

You take in oxygen and it goes to your lungs. It spreads through your body, going through your bloodstream, and going to your heart. The excess oxygen turns into carbon dioxide leaves through your mouth. When it leaves, the plants take the carbon dioxide and turn it back into oxygen, and repeating this process.

(I'm pretty sure this is the answer. Hope it helps:)

Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

What are the functions of hemoglobin?

Hemoglobin is a protein in your red blood cells that carries oxygen to your body's organs and tissues and transports carbon dioxide from your organs and tissues back to your lungs.

Hemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein present in red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the respiratory organs to the rest of the body.

Hemoglobin is essential for transferring oxygen in your blood from the lungs to the tissues. Myoglobin, in muscle cells, accepts, stores, transports and releases oxygen.

The core layer is located at the center of the Earth.

What is center of earth?All land surfaces on Earth have a geometric center that is located at the planet's geographic center. According to geometry, it is the centroid of all land areas inside the two dimensions of the geoid surface, which roughly represents the exterior shape of the planet.The extremely hot and dense core of our planet is called the Earth's core. Underneath the chilly, brittle crust and the largely solid mantle is the ball-shaped core. The Earth's core is around 2,900 kilometres (1,802 miles) below the surface and has a radius of about 3,485 kilometres.Since the temperature and pressure significantly rise as we travel more inside the planet, we are unable to reach the center of it.

of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?

Answers

Cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Cell A is more efficient at exchanging substances with the surrounding environment than cell B because it has the larger surface-area-to-volume ratio. Larger surface area of the cell exchanges more substances with the surrounding environment.

While on the other hand, lower surface area of the cell exchanges less materials with the environment so we can conclude that cell A is more efficient at exchanging substances due to larger surface area to volume ratio.

Rainbow trout are a freshwater fish native to streams and lakes along the western coast of North America. While studying streams in the eastern United States, an ecologist noticed that rainbow trout were abundant in the ecosystem, but other native species of fish were almost entirely missing. She also observed lower populations of macroinvertebrates. The ecologist wondered why there were so few native fish species and macroinvertebrates. By reading ecological reports of the area, the scientist learned that rainbow trout had been introduced to the streams for sport fishers to catch. Initially, 100 fish had been introduced, but the ecologist conducted a field survey and estimated that over 1,000 rainbow trout now lived in the streams. She also read from other studies that rainbow trout feed primarily on macroinvertebrates. Which question most closely relates to the ecologist's observations and the collected scientific data on river ecosystems? Do the native fish species have a disease? Are rainbow trout displacing native species by outcompeting them for food? Did pollution kill off the native fish species?
