fossil fuel burning

A climate change is a phenomenon that known that as greenhouse effect. burning fossil is one of the important effect of climate change. because it makes our earth warmer. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming. If this does not happen, the cold of the earth will cause lack of food, extinction of animals, freezing of plants and lack of oxygen for milions of peaple. Fossil fuels are formed from the decomposition of buried carbon-based organisms that died millions of years ago.

Most vehicles like cars, trucks, ships, and planes use fossil fuels, and this releases greenhouse gases, including carbon dioxide. When we package and produce food, it also lets out carbon dioxide, methane, and other gases that trap heat. The carbon dioxide, which sticks around for a very long time, is a big reason behind global warming and climate change caused by human actions.

Effects of climate change

Climate change means the weather getting hotter or colder and less or more rain and snow. If we use a lot of fossil fuels, gases go into the air that cause these changes.

These changes can bring many problems. For example, temperatures can get higher, there can be less or more rain, and there can be more water in the oceans. These problems can affect the lives of sea creatures and even the land. ·Right now, climate changes are already causing harm to people and animals. If we don’t solve these problems, in the future, we might lose a lot of crops, more animals and plants could disappear, and different communities could face big problems.

Materials

•   Four 12-inch pipe cleaners (2 of one colour and 2 of another)
• Four 6-inch pipe cleaners (2 of one colour and 2 of another)

Interphase

Interphase is the stage of the cell cycle in which a cell grows, duplicates its DNA, and prepares for division.

benefit of interphase is duplicates chromosomes. One of the limitation of interphase is growth issues.

Prophase

In prophase, chromosomes are in the nuclear member, also their beside centrioles.

there are 4 chromosomes in the prophase.

One of the benefits of prophase can be Chromosomes shorting and one of the limitations of prophase can be High energy combustion.

Metaphase

Chromosomes are on the middle of the shape of metaphase.

one of the benefits of metaphase is preventing cell division errors.

limitation on metaphase is possible chromosome alignment errors during cell division.

Anaphase 

chromosomes are dissociated in anaphase.

anaphase distributing chromosome.

anaphase limitation is genetic instability.

Telophase 

telophase is in tow part and chromosomes division in them.

telophase cleavage the cell.

telophase limitation is failure cytokinesis.
