Answer:
The possible fate of the cell that it may turn cancerous.
Explanation:
The cells present in the body generally work in harmony. However, if a cell attains a mutation, it can make it proliferate in the case when it should not do, and make it thrive in the case when other cells are dying. Due to proliferation, the unusual cell produces more abnormal cells also known as cancerous cells. These cancerous cells become more favorable in comparison to the normal cells due to the phenomenon of natural selection. These cells eventually result in a lethal form of tumors.
In the normal cells, the destructed gene or the damaged cells get repaired easily, in case if the damage is worse the cell dies. A protein known as p53 helps in repairing damaged cells or kills them if the damage is too severe. But in the case of cancer cells, the p53 protein does not work appropriately as they possess a mutated or changed form of p53 protein. Thus, in the case of cancerous cells, the rate of repair lags behind the rate of mutation, which makes the cancer cells thrive and increase in numbers resulting in further destruction.
Clean or green energy helps in releasing lesser air pollution and lesser carbon dioxide. That contributes in lowing down global warming and subsequent disasters like tsunami because of glacier melting , more unexpected climate changes like unexpected long-period storms, flood, typhoons, etc.
Hope this would help.
Physics is very common in our lives, and of course this also applies to the performance of a runner.
For example, he or she needs to understand the air resistance when running, they may need to find a way to reduce the most air resistance that is against them so that they can show their best performance.
Or another example is they may need to find out the friction acting on between their feet and the track, they may need to adjust their training in different textures of running tracks, as each acts a different amount of friction.
Answer:
b. <em>Homo neanderthalensis</em>
Explanation:
<em>Homo neanderthalensis </em>are extinct species of the Homo genus which lived in Eurasia until 40000 years ago. They initially lived in Europe and then migrated to Central and Southwest Asia. Compared to modern humans, they had shorter legs and bigger bodies.
They have been known to construct huts out of mammoth bones. Archaelogists discovered a Neanderthal hut structure made of mammoth bone which is considered to be 44000 years old. This structure was 26 feet wide and mostly used for domestic purposes. Previously <em>Homo neanderthalensis </em>were considered primitive creatures who lived in natural caves but after this discovery it has been accepted that they were also advanced.
