One of the most common sources of phosphate pollution that has led to eutrophication has resulted from the use of

Answers

Answer:

Phosphate fertilizers

Explanation:

One of the most common sources of phosphate pollution is run-offs from phosphate fertilizer from agricultural processes. Farmers deploy phosphate-containing fertilizers to soils in other to improve the overall fertility of the soil and the yield of crops.

Some of these fertilizers find their ways into nearby water bodies through washing up by erosion thereby raising the phosphate levels of these water causing eutrophication.

Other common sources of phosphate pollution include industrial and domestic run-off as well as detergents although phosphate-containing detergents are now becoming a thing of the past.

How might a reduction in species diversity affect the other three components of biodiversity?

Answers

Answer:

if the species diversity in an ecosystem or on the Earth gets reduced, it will affect the balance biodiversity and its other components. The three components of biodiversity are: ecosystem, species, and genetic diversity.

Biodiversity is defined as the variety of life forms existing in different ecosystems on planet Earth.

The three components of biodiversity are:

genetic diversity, species diversity, ecosystem diversity.

If there is a reduction in the species diversity, there will be an imbalance in biodiversity, which is integrated, where each living being has an essential role in the maintenance and sustainability of the planet.

Biota reduction will therefore directly impact the ecosystem and will alter the correct flow of environmental balance.

It is possible to see through history, that many species of animals were extinct by human exploitation and this action cannot be reversed.

Therefore, it is essential to make each individual aware of the importance of developing sustainability for the preservation of nature and the quality of life of current and future generations.

why is cytoplasm present in all cells?

Answers

Answer: Cytoplasm is present in all cells because it is the placeholder of the cell. It helps to fill in the cell and holds all the organelles in their place. If the cell did not have cytoplasm, the cell would be deflated and some certain materials would not have the ability to pass easily from one organelle to another. Hope this helps!

Tissue

Tissues are groups of similar cells that have a common function. The four basic tissue types are epithelial, muscle, connective, and nervous tissue. Each tissue type has a characteristic role in the body:

Epithelium covers the body surface and lines body cavities.

Muscle provides movement.

Connective tissue supports and protects body organs.

Nervous tissue provides a means of rapid internal communication by transmitting electrical impulses.

Why do cells need to be able to control movement of substances across the plasma membrane?

Answers

Answer:

To move substances against a concentration or electrochemical gradient, the cell must use energy. Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances needed by living cells in the face of these passive movements.

Explanation:

Based on their half-life values, which radioisotope would be best suited to determine the age of a woolly mammoth bone

Answers

Answer:

Wolly mammoths existed about five million years ago. Therefore, based on their half-life, the radioisotope which would be best suited to determine the age of a wooly mammoth bone is Uranium - 235 whose half-life is approximately 700 million years.

Explanation:

Uranium 235 is a variant or an isotope of Uranium. Isotopes are a derivative of a particular chemical element which are alike but different in the number of nucleons they contain.

In relation to age testing, the time taken for any specified property to decrease by half of its original value is called a half-life.

Thus the radioactivity of Uranium - 235 takes about 700 million years to fall to half it's original value.

Because of its half-life, Uranium - 235 is the best used when dating very old fossils.

a. a virus is much larger in size than a bacterial cell

b. a virus always causes more severe disease than a bacterial cell

c. a virus can never reproduce on its own, but a bacterial cell can

d. a virus does not contain genetic material, but a bacterial cell does

Answer:

c. a virus can never reproduce on its own, but a bacterial cell can

Explanation:

a. a virus is much larger in size than a bacterial cell - this is false, a virus is much smaller than a bacterial cell

b. a virus always causes more severe disease than a bacterial cell - this is false, both can be deadly pathogens

c. a virus can never reproduce on its own, but a bacterial cell can - this is true. Viruses are not cellular and need a host cell to reproduce, but bacteria do not.

d. a virus does not contain genetic material, but a bacterial cell does - this is false, viruses contain either a DNA or RNA genome
