Thy are related to evolution cause fossils show how long ago those creatures were made and compares to the the things we have now
It would be winter in Canada when it is summer in Australia. First off, they are on opposite sides of the world -- Australia is in the southern hemisphere, the earth is tilted to the sun, which of course would cause the hot weather. Canada is in the northern hemisphere, which is opposite and further away from the sun.
Answer:
rainfall made sufficiently acidic by atmospheric pollution that it causes environmental harm, typically to forests and lakes. The main cause is the industrial burning of coal and other fossil fuels, the waste gases from which contain sulfur and nitrogen oxides, which combine with atmospheric water to form acids.
Ozone depletion, gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
the concentration of toxins in an organism as a result of its ingesting other plants or animals in which the toxins are more widely disbursed.
an antigenic poison or venom of plant or animal origin, especially one produced by or derived from microorganisms and causing disease when present at low concentration in the body.
A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. Likewise, biodiversity loss describes the decline in the number, genetic variability, and variety of species, and the biological communities in a given area. This loss in the variety of life can lead to a breakdown in the functioning of the ecosystem where decline has happened.
Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund.Nov 6, 2019
Explanation:
The answer is chloroplasts.
Answer:
True
Explanation:
Water molecules can move across a membrane due to size of the molecule. Water molecules are small in size thus can diffuse easily. Big size molecules cannot move across the membrane because the membrane is selectively permeable with tiny pores that allow free passage of gases and water.
