1. There are lots of factors that can change the ecosystem and can affect populations. But the most common ones are 1 climate changes, 2 changes in resources of land or food or 3 changes in predation. All these 3 factors can alter the food web thus affecting the population of different species.

For example, if suddenly the number of sharks increases, the whole food web is altered. More sharks consume more fishes, so, the population of fishes are changed.

2. Climate changes are different in different part of the world. But in a whole, the main changes are 1 rising temperature 2 rising in sea level 3 increase in rainfall (or decrease in some places) 4 increase occurance of typhoons and floodings

Some of these changes actually bring benefits to certain people and places, for example, some dry areas can now have a longer crop growing period because they have more rainfall now. Or, less people die from coldness in temperate areas.

However, most of these changes also brings problems and harms to life. For example, tropical diseases like malaria or dengue fever are spreading to temperate areas too, or, animal habitats are destroyed due to flooding.

3. When we say human activities, we mining talk about activities like burning of fossil fuels, or deforestation etc. Many of these activities increases the amount of greenhouse gases like carbon dioxide in the atmosphere thus intensifying the greenhouse effect. Greenhouse effect is necessary for earth and lives, but, the thing is humans are intensifying too much. The whole earth is getting hotter and hotter.

When the earth gets hot, ice sheets in polar regions may melt and thus killing animals there like polar bears. It can also promote the occurrence of acid rain and more lives are killed, especially aquatic animals and plants.

What is true about elements and compounds elements contain two or more compounds conpounds contain two or more elements compound
statuscvo [17]

Answer:

Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.

Explanation:

Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.

The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.

The bonds types that form compounds can be:

  • <em>Ionic bond.</em>
  • <em>Covalent bond.</em>
  • <em>Coordinated covalent bond.</em>
  • <em>Metallic bond.</em>

It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.

Describe the function of sodium and potassium in the generation of an action<br> potential.
larisa [96]

Answer:

The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential. The sodium channels close at the peak of the action potential, while potassium continues to leave the cell.
